                                  THE COMPANY
 
   
     RailWorks Corporation was formed in March 1998 to become a leading
nationwide provider of rail system services, including construction and
rehabilitation, repair and maintenance, and related products. Management
selected the Founding Companies, which will be acquired by RailWorks Corporation
concurrently with the closing of the Offering, based on their regional or local
market leadership, diverse and long-standing customer relationships,
profitability and geographic diversity. The Combination will establish a
significant operating enterprise which management believes will serve as the
foundation for a consolidation of the highly-fragmented rail system services and
products industry. The Company's strategy is based on providing a full range of
rail-related services and products on a national basis and offering integrated
rail system solutions under the "RailWorks" brand. For the year ended December
31, 1997, on a pro forma as adjusted basis, the Company had revenue of $256.5
million, operating income of $11.2 million and net income of $5.4 million. For
the three months ended March 31, 1998, on a pro forma as adjusted basis, the
Company had revenue of $61.8 million, operating income of $1.5 million and net
income of $655,000. Based on estimates of the Founding Companies, management
estimates that approximately 68.4% of the Company's pro forma as adjusted
revenue for the year ended December 31, 1997 was derived from rail-related
operations and 31.6% was derived from non-rail related operations.
    
 
     The rail passenger and freight industries have undergone significant
changes in recent years. As a result, management believes that the rail system
services and products industry presents a significant growth opportunity for the
Company due to (i) increased governmental and private investment in new
construction projects and rehabilitation of rail systems, (ii) ongoing
reconfiguration and rationalization of rail infrastructure primarily due to
industry consolidation, (iii) the use of fewer vendors by rail system operators
and (iv) the fragmented nature of the rail system services and products
industry. Based on information from the American Association of Railroads
("AAR") and the American Public Transit Association ("APTA"), management
believes that expenditures by rail system operators for new construction,
rehabilitation, repair and maintenance were approximately $14 billion in 1997.
Shortline railroads, industrial companies and transit authorities generally
outsource rail-related work because they lack the know-how, specialized
equipment and resources to cost-effectively install signal systems or build and
maintain their own tracks. Management believes that as Class I railroads
continue to seek to reduce costs they will increasingly outsource rail-related
                                        1
<PAGE>   5
 
work to companies that can offer integrated rail system services and products in
multiple locations. Finally, the rail system services and products industry is
highly fragmented, presenting a consolidation opportunity for the Company.
Management believes that an integrated rail system services and products
provider would have a competitive advantage over smaller competitors. While
there are competitors that have the bonding capacity required to undertake large
projects, many competitors do not have such capacity and are unable to provide
the integration of design, construction, rehabilitation, repair and maintenance
services increasingly sought by rail system operators.
 
COMPETITIVE STRENGTHS
 
     Breadth of Services and Products.  Management believes that rail system
operators are increasingly seeking to purchase services and supplies on an
integrated basis from fewer vendors. Management further believes that the
Company will offer a broader range of services and products than most industry
participants. The Company's service and product offerings include (i)
construction and rehabilitation of track, signaling, communications, electrical
and other track-related systems, (ii) repair and maintenance of these systems,
(iii) a broad range of rail-related products, including rail, ties, spikes,
frogs (rail intersections), tie plates and ballast and (iv) for non-rail
customers, electrical installation services and concrete products. Based on
estimates of the Founding Companies, management estimates that revenue from
rail-related (i) construction and rehabilitation, (ii) repair and maintenance
and (iii) other track materials ("OTM") and products accounted for 46.5%, 15.4%
and 6.5%, respectively, of the Company's pro forma as adjusted revenue for the
year ended December 31, 1997 and non-rail services and products accounted for
31.6% of this revenue.
 
     Diverse Customer Base.  The Founding Companies have long-standing
relationships with a wide variety of customers, including: (i) commercial and
industrial companies such as Commonwealth Edison, United States Steel, and
Terminal One at JFK International Airport, which have contracted with the
Company for track construction and maintenance or non-rail electrical
contracting work; (ii) transit authorities such as the New York Metropolitan
Transit Authority, the Los Angeles Metropolitan Transit Authority and the
Baltimore Metropolitan Transit Authority, which have contracted with the Company
for electrical installations, signaling, communications or station projects;
(iii) shortline railroads such as Indiana Southern Railroad Company, Branford
Steam Railroad and I&M Rail Link, which have contracted with the Company for
track construction and maintenance work or product supply; and (iv) Class I
railroads such as Illinois Central Railroad, Union Pacific Railroad and CSX
Transportation, which have utilized the Company for repair, maintenance,
construction or engineering.
 
     Expansive Geographic Coverage.  The Company has offices in 17 states and
has provided services and products to customers throughout the United States.
The Company's 33 facilities provide it with a geographically diverse mix of
established operating bases which enable it to undertake projects in a more cost
effective manner than would be possible absent a local facility. The Company
also has the ability to mobilize equipment and technical specialists throughout
the United States to maximize asset utilization and to complete projects in
remote locations.
 
STRATEGY
 
     The Company's goal is to become a leading provider of integrated rail
system solutions, offering a full range of rail-related services and products to
a diverse base of customers throughout the United States. In addition, the
Company expects to continue to provide non-rail services and products in
response to market opportunities. Key elements of the Company's strategy include
the following:
 
     - Provide Integrated Solutions for Rail Systems.  Management believes that
       rail system operators are increasingly seeking to outsource their
       construction, rehabilitation, repair and maintenance requirements and to
       utilize fewer vendors to provide a full range of these services and
       related products. As a result of the Combination, the Company will be
       able to
 
                                        2
<PAGE>   6
 
       provide its customers with integrated rail system solutions that
       management believes can be efficiently designed, constructed, maintained,
       operated and supplied, resulting in lower costs over the life cycle of
       customers' rail assets.
 
     - Capitalize on Scale and Geographic Coverage.  The Company believes that
       the increased scale that will be achieved through the Combination will
       position it to undertake larger rail-related projects that were beyond
       the scope of those previously undertaken by the individual Founding
       Companies. Each of the Founding Companies was previously constrained by
       applicable bonding limits and the limited size of its workforce. The
       Company also intends to utilize its geographic scope to develop a
       national accounts program to serve rail customers with multiple sites and
       "cross-sell" its broad range of rail-related services and products. The
       Company currently has very limited international operations but over time
       it may increase its activity in international markets, where
       privatizations of railroads and large transit projects are creating
       increased demand for sophisticated design and construction management
       services.
 
     - Reduce Operating Costs.  The Company believes that the scale of its
       operations and administrative integration of the Founding Companies
       following the Combination will provide it with a better cost structure
       than its regional and smaller competitors. Key areas in which the Company
       expects to achieve cost savings include (i) purchasing of equipment and
       supplies, (ii) insurance expenses, (iii) financing costs and (iv)
       utilization of equipment and the Company's workforce. The Company also
       expects to reduce administrative expenses through the integration of
       certain accounting, financing, human resources and other functions.
 
     - Expand Through Acquisitions.  The rail system services and products
       industry is highly fragmented, and the Company believes that it is
       well-positioned to pursue the consolidation of these segments on a
       nationwide basis. Following the Offering, the Company expects to pursue
       an acquisition program that will include (i) strategic acquisitions
       intended to expand the Company's geographic coverage throughout the
       United States and broaden its lines of services and products, (ii)
       acquisitions intended to position the Company to offer its customers
       complementary services and products and (iii) smaller "tuck-in"
       acquisitions intended to add density and operating leverage within the
       Company's current markets. The Company believes that the experience and
       industry reputations of the senior managers of the Founding Companies and
       senior corporate management of the Company will provide it with a
       competitive advantage in identifying, completing and integrating these
       acquisitions. The Company does not intend to expand its non-rail business
       through acquisitions.
 
     - Leverage Management Expertise.  The senior managers of each of the
       Founding Companies have an average of 14 years of experience in the rail
       system services and products industry. The Company will utilize a
       management structure which will enable these individuals to focus on
       operations rather than administrative tasks. In addition, the Company's
       Chief Executive Officer, Chief Financial Officer and Chief Operating
       Officer each have in excess of 15 years of experience in the
       transportation industry, including, in the case of John Larkin (the
       Company's Chief Executive Officer), approximately 11 years of experience
       as an equity research analyst focusing on the transportation industry.
       Senior management of the Company will coordinate the operations of the
       Founding Companies, provide strategic guidance for the Company, implement
       the Company's acquisition program and promote the development of national
       accounts. As part of this strategy, the Company intends to foster a
       culture of cooperation and teamwork among the Founding Companies that
       emphasizes dissemination of "best practices" among its regional and local
       management teams and joint bidding on larger projects. For example,
       management believes it can successfully implement best practices in the
       areas of 24-hour emergency rerailment services, annual maintenance
       contracts and efficient inventory management.

                                THE COMBINATION
 
   
     Simultaneously with and as a condition to the closing of the Offering,
RailWorks Corporation will consummate the Combination pursuant to agreements
that it has entered into with the Founding Companies and their stockholders
(each an "Acquisition Agreement" and together the "Acquisition Agreements").
Assuming an initial public offering price of $12.00 per share, the aggregate
consideration to be paid by RailWorks Corporation in the Combination will be
$158.3 million (subject to adjustment), which consists of (i) $51.9 million in
cash to be paid from the proceeds of the Offering (representing 93.6% of the
estimated net proceeds of the Offering) and (ii) the $106.4 million estimated
fair value of 8,367,648 shares of Common Stock to be issued to the stockholders
of the Founding Companies. In addition, in connection with the Combination, the
Company will assume $36.5 million of indebtedness of certain of the Founding
Companies (including approximately $1.6 million of indebtedness incurred to
partially finance the redemption of shares of common stock of a Founding Company
held by an employee stock ownership plan (an "ESOP")). Such indebtedness will be
repaid with a portion of the proceeds of the Offering (representing 7.1% of the
estimated net proceeds of the Offering and with borrowings under the Company's
Credit Facility). The purchase price for each Founding Company was determined
based on negotiations between RailWorks Corporation and the Founding Companies.
The factors considered by the parties in determining the purchase price were
historical operating results, growth rates and assets and liabilities of the
Founding Companies, and such factors were applied consistently to each Founding
Company. For additional information regarding the consideration to be paid to
the owners of each Founding Company, see "Formation of the Company -- The
Combination."
    
 
   
     As a result of the Combination, all 22 Founding Companies will become
wholly-owned subsidiaries of RailWorks Corporation. The consummation of each
acquisition that is a part of the Combination (each an "Acquisition" and
together the "Acquisitions") is contingent upon the consummation of the Offering
and customary closing conditions. The Acquisition Agreements require certain
executive officers of each of the Founding Companies to enter into employment
agreements with their respective Founding Companies effective upon consummation
of the Combination. In addition, executive officers of certain of the Founding
Companies will be elected to the Board of Directors of the Company following the
consummation of the Offering. After the Offering, the stockholders of the
Founding Companies, management of the Company and IPO Development Company L.L.P.
("IPODC") will own in the aggregate 66.8% of the outstanding Common Stock,
assuming the Underwriters' over-allotment option is not exercised. The Selling
Stockholders will sell shares of Common Stock received by them in the
Combination if the Underwriters exercise their over-allotment option and,
therefore, the Selling Stockholders may be deemed to be "statutory underwriters"
for purposes of the Securities Act of 1933 (the "Securities Act"). As such, the
Selling Stockholders may be liable under the securities laws for material
misstatements or omissions made in connection with the Offering. See "Formation
of the Company," "Use of Proceeds," "Management's Discussion and Analysis of
Financial Condition and Results of Operations," "Management -- Employment
Agreements," "Certain Relationships and Related Party Transactions," "Shares

Statements and the notes thereto appearing elsewhere in this Prospectus.

                  SUMMARY PRO FORMA AS ADJUSTED FINANCIAL DATA
 
   
     RailWorks Corporation was formed in March 1998 to acquire the Founding
Companies simultaneously with and as a condition to the consummation of the
Offering. For accounting and financial statement purposes, Comstock has been
identified as the "accounting acquiror" consistent with the accounting
requirements of Staff Accounting Bulletin ("SAB") No. 97 of the Securities and
Exchange Commission (the "Commission") because its owners will receive the
largest portion (32.8%) of the shares of Common Stock issued to the Founding
Companies in the Combination. The acquisitions of the remaining Founding
Companies will be accounted for as purchases in accordance with Accounting
Principles Board ("APB") No. 16. The summary pro forma as adjusted data are not
necessarily indicative of the operating results or financial position that would
have been achieved had the Combination and Offering been consummated and should
not be construed as representative of the Company's future operating results or
financial position. The summary pro forma as adjusted financial data should be
read in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations," the Unaudited Pro Forma As Adjusted
Financial Statements and the notes thereto and the historical financial
statements of the Founding Companies and the notes thereto included elsewhere in
this Prospectus. The Company anticipates that following the Combination it will
realize savings from: (i) more efficient utilization of equipment and the
Company's workforce; (ii) the combination of administrative functions such as
accounting, finance and human resources and certain other functions at the
corporate level; (iii) better pricing on purchases of equipment and supplies;
and, to a lesser extent, (iv) joint bidding on larger rail projects. Those
savings, which cannot be quantified or reasonably estimated, have not been
reflected in the Unaudited Pro Forma As Adjusted Financial Statement or in the
summary data presented below.

                                  RISK FACTORS
 
     An investment in the shares of Common Stock offered hereby involves a high
degree of risk. Prospective investors should consider carefully the following
risk factors, in addition to the other information contained in this Prospectus,
in evaluating an investment in the shares of Common Stock offered hereby.
 
     Absence of Combined Operating History.  RailWorks Corporation was formed in
March 1998 and has conducted no operations to date. RailWorks Corporation has
entered into agreements to acquire the Founding Companies simultaneously with
the closing of the Offering. The Founding Companies have been operating
independently and the Company may not be able to integrate these businesses
successfully on an economic basis. The Company's management group has been
assembled only recently and the management control structure is still in its
formative stages. The pro forma as adjusted results of operations of RailWorks
and the Founding Companies cover periods when RailWorks and the Founding
Companies were not under common control or management and may not be indicative
of the Company's future results of operations. Most of the senior managers of
the individual Founding Companies will remain at the Founding Company level, in
accordance with the Company's decentralized management philosophy. Currently,
the executive officers of RailWorks consist of John G. Larkin, its Chairman of
the Board and Chief Executive Officer, Michael R. Azarela, its Executive Vice
President and Chief Financial Officer, John Kennedy, its Vice President and
Chief Operating Officer, and Harold C. Kropp, Jr., its Vice President and Chief
Accounting Officer. Upon consummation of the Combination, these officers will be
responsible for the Company's day-to-day management as a combined entity.
Management may not be able to oversee the combined entity effectively or to
implement effectively the Company's operating strategies. Any failure by the
Company to implement its strategies, integrate the Founding Companies without
substantial costs, delays or other operational or financial difficulties, or
oversee effectively the combined entity could have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Formation of the Company," "Business -- The Founding Companies" and
"Management."
 
   
     Valuations of the Founding Companies Unrelated to Appraisals or Asset
Values.  Valuations of the Founding Companies have not been established by
independent appraisals, but have been determined through negotiations between
RailWorks and representatives of each of the Founding Companies. The
consideration being paid for each of the Founding Companies, including Founding
Companies whose stockholders will become affiliates of the Company upon
consummation of the Offering, is based exclusively on these private negotiations
between RailWorks and the representatives of each Founding Company. The factors
considered by the parties in determining the purchase prices for the Founding
Companies were historical operating results, growth rates and the assets and
liabilities of the Founding Companies. Such factors were applied consistently to
each Founding Company. The consideration to be paid does not necessarily bear
any relationship to the net book value of the acquired assets or to any other
recognized indicia of value. For example, valuations of the Founding Companies
determined solely by appraisals of the acquired assets would be less than the
consideration being paid by RailWorks for the Founding Companies. In particular,
the aggregate purchase price to be paid in the Combination is $124.7 million
greater than the estimated fair value of the net assets acquired. Since Comstock
is deemed the "accounting acquiror," no goodwill is being recorded with respect
to the Acquisition of Comstock. As a result, only $78.5 million of this excess
is reflected as goodwill in the Unaudited Pro Forma As Adjusted Financial
Statements as a result of the Combination. The future performance of the
Founding Companies may not be commensurate with the consideration being paid to
acquire the Founding Companies or the price of the Common Stock offered hereby.
See "-- Amortization of Intangible Assets" and "Formation of the Company -- The
Combination."
    
 
     Risks Associated with Acquisition Strategy and Financing.  The Company
intends to grow significantly through the acquisition of additional businesses
in the rail system services and products industry. See "Business -- Strategy."
This strategy will entail reviewing and potentially reorganizing
                                        8
<PAGE>   12
 
acquired business operations, corporate infrastructure and systems and financial
controls. Unforeseen expenses, difficulties, complications and delays frequently
encountered in connection with the rapid expansion of operations could inhibit
the Company's growth.
 
     There can be no assurance that the Company will maintain or accelerate its
growth or anticipate all of the changing demands that expanding operations will
impose on its management personnel, operational and management information
systems and financial systems. The Company may not be able to identify, acquire
or manage profitably additional businesses or to integrate successfully any
acquired businesses into the Company without substantial costs, delays or other
operational or financial difficulties. Any failure by the Company to do so could
have a material adverse effect on its business, financial condition and results
of operations.
 
     The timing, size and success of the Company's acquisition efforts and any
associated capital commitments cannot be readily predicted. The Company
currently intends to finance future acquisitions by using shares of its Common
Stock, cash or a combination of Common Stock and cash. If the Common Stock does
not maintain a sufficient market value, or if potential acquisition candidates
are otherwise unwilling to accept Common Stock as part of the consideration for
the sale of their businesses, the Company may be required to utilize more of its
cash resources, if available, in order to initiate and maintain its acquisition
program. If the Company does not have sufficient cash resources, its growth
could be limited unless it is able to obtain additional capital through debt or
equity financings. There can be no assurance that the Company will be able to
obtain additional financing for its acquisition program on terms that the
Company considers acceptable. To the extent the Company uses Common Stock for
future acquisitions, dilution may be experienced by existing stockholders,
including the purchasers of Common Stock in the Offering. See "Use of Proceeds"
and "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Pro Forma As Adjusted Liquidity and Capital Resources."
 
     Risks Related to Internal Growth and Operating Strategies.  Key elements of
the Company's strategy are to increase the revenue of the Founding Companies and
any subsequently acquired businesses and to reduce their operating expenses. The
Company's ability to increase revenue will be affected by various factors,
including demand for rail system services and products, the success of
cross-selling and the Company's ability to develop a national accounts program.
The growth of the Company may also be dependent on increased outsourcing by rail
system operators. Many of these factors are beyond the control of the Company,
and the Company's strategies may not be successful or the Company may be unable
to generate cash flow adequate for its operations and to support internal
growth. A key component of the Company's strategy is to operate on a
decentralized basis, with management of the Founding Companies retaining
responsibility for day-to-day operations. If proper business controls are not
implemented, this decentralized operating strategy could result in inconsistent
operating and financial practices at the Founding Companies and subsequently
acquired businesses, which could have a material adverse effect on the Company's
business, financial condition and results of operations. See
"Business -- Strategy."
 
     Rail System Cyclicality.  Demand for rail system services and products
could fluctuate in conjunction with overall economic conditions. In economic
downturns, rail system operators may defer certain construction, rehabilitation,
repair and maintenance projects and purchases of related products to conserve
cash in the short term. Also, reductions in freight traffic due to economic
downturns or other factors may reduce demand for the Company's construction,
rehabilitation, repair and maintenance services and related products. In
economic upturns, railroads, particularly Class I railroads, experience heavier
traffic demands that can cause problems associated with congestion. The
operational problems related to congestion have an unpredictable impact on
railroad expenditures for construction, rehabilitation, repair and maintenance
services and related products, including those provided by the Company. During
periods of peak usage, rail system owners may defer certain expenditures due to
their need to address the operational challenges caused by these conditions.
Such uncertainties may be exacerbated by certain other issues, such as
 
                                        9
<PAGE>   13
 
the possibility of heightened government regulation during periods of congestion
and the internal challenges of managing railroad operations as the Class I
railroads continue to consolidate.
 
     Exposure to Downturns in Commercial Construction.  Approximately 26.2% of
the Company's pro forma as adjusted revenue for the twelve months ended December
31, 1997 was derived from installation of electrical systems in newly
constructed or renovated commercial buildings and power and industrial plants.
The demand for electrical installation services is affected by fluctuations in
the level of new construction and renovation of commercial buildings, which
reflect the cyclical nature of the construction industry and depend upon general
economic conditions, changes in interest rates and other related factors.
Downturns in levels of commercial construction and renovation would have a
material adverse effect on the Company's business, financial condition and
results of operations. Further, the Company's electrical installation business
is focused in the Northeastern United States and is therefore particularly
susceptible to economic downturns in that region. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Results of
Operations of the Founding Companies -- Comstock Holdings, Inc."
 
     History of Losses; Fluctuations in Quarterly Operating Results.  From time
to time, primarily due to industry cyclicality and uncertainties inherent in the
competitive bidding process, certain of the Founding Companies have experienced
net losses. See "-- Competitive Bidding; Risks of Fixed Price Contracts." For
the year ended December 31, 1995, Comstock incurred a net loss of approximately
$20 million, primarily as a result of a one-time accounting charge for the
impairment of certain long-lived assets. In addition, Comtrak Construction, Inc.
and Merit Railroad Contractors, Inc. incurred net losses in 1997 and U.S.
Trackworks, Inc. incurred a net loss in 1996 primarily due to insufficient
revenues to support fixed overhead. There can be no assurance that these
Founding Companies, other Founding Companies or the Company will be profitable
in the future. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
     In addition, the Founding Companies have in the past experienced quarterly
variations in revenue, operating income (including operating losses), net income
(including net losses) and cash flows (including cash flow deficits) as a result
of projects commenced and completed during a quarter, the number of business
days in a quarter and the size and scope of projects. A variation in the number
of projects, progress on projects or the timing of the initiation or completion
of projects can cause periods in which certain operating resources are not
generating revenue and can cause significant variations in operating results
between reporting periods. Negative fluctuations have been particularly
pronounced, and net losses have been incurred, in the first and fourth calendar
quarters, generally due to adverse weather conditions. For example, over the
last two years each of Comtrak Construction, Inc., H.P. McGinley, Incorporated,
Kennedy Railroad Builders, Inc., Merit Railroad Contractors, Inc., New England
Railroad Construction Company, Inc., Railroad Service, Inc., and U.S.
Trackworks, Inc. have experienced losses in the first quarters of certain fiscal
years. The Company expects to continue to experience such quarterly fluctuations
in operating results (including possible net losses) and may also experience
quarterly fluctuations as a result of other factors, including the loss of a
major customer and additional general and administrative expenses to acquire and
support new business. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
   
     Amortization of Intangible Assets.  Approximately $83.5 million, or 42.6%,
of the Company's pro forma as adjusted total assets as of March 31, 1998,
consists of goodwill and other intangibles arising from the Combination
(assuming an initial public offering price of $12.00 per share). Goodwill is an
intangible asset that represents the difference between the aggregate purchase
price for the assets acquired and the amount of such purchase price allocated to
such assets for purposes of the Company's pro forma as adjusted balance sheet.
The Company is required to amortize the goodwill and other intangibles from the
Combination over a period of time, with the amount amortized in a particular
period constituting an expense that reduces the Company's net income for that
period. The amount of goodwill amortization, however, will not give rise to a
deduction for tax purposes. In addition, the Company will be required to
amortize the goodwill and other intangibles,
    
                                       10
<PAGE>   14
 
   
if any, from any future acquisitions. A reduction in net income resulting from
the amortization of goodwill and other intangibles may have an adverse impact
upon the market price of the Company's Common Stock. The Company plans to
amortize goodwill associated with the Combination over a period of 40 years and
amortize other intangibles associated with the Combination over a period of 10
years, and will continue to evaluate whether events or circumstances have
occurred that indicate that the remaining useful life of goodwill and other
intangibles may warrant revision. Additionally, in accordance with the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of," the Company will evaluate any potential goodwill for
impairments by reviewing the future cash flows of the operations of the acquired
entities and comparing these amounts with the carrying value of the associated
goodwill and other intangibles.
    
 
     Competition.  The rail system services and products industry is highly
competitive. The Company competes with other companies that provide rail system
construction and rehabilitation, repair and maintenance, electrical signaling,
communication and installation services and related products, some of which have
significantly greater resources than the Company. An inability of the Company to
compete successfully against its existing and future competitors would have a
material adverse effect on its business, financial condition and results of
operations. Management believes that the Founding Companies compete effectively
in their industries. There are no substantial barriers to entry and additional
competitors with greater resources than the Company may enter the industry and
compete effectively against the Company. Certain competitors may also provide a
broad range of services and products and may have sufficient bonding capacity to
undertake large projects. The Company also provides electrical contracting
services to non-rail industrial and commercial customers. While management
believes that the Company will be able to compete effectively in the non-rail
electrical contracting business, this industry is highly competitive and is
served by small, owner-operated private companies, public companies and several
large regional companies. Additionally, the Company could face competition in
the future from other competitors entering this market. See
"Business -- Competition."
 
     Public Sector Contracts and Funding.  The rail system services and products
business involves contracts that are supported by funding from federal, state
and local governmental agencies, as well as contracts with such agencies
("public sector contracts"). Public sector contracts are subject to detailed
regulatory requirements and public policies, as well as funding priorities.
These contracts may be conditioned upon the continuing availability of public
funds, which in turn depends upon lengthy and complex budgetary procedures, and
may be subject to significant pricing constraints. Moreover, public sector
contracts may generally be terminated for reasons beyond the control of the
contractor, including when such termination is in the best interests of the
governmental agency. There can be no assurance that these factors or others
unique to public sector contracts will not have a material adverse effect on the
Company's business, financial condition and results of operations.
Based on estimates of the Founding Companies, management estimates that the
Company derived approximately 55% of its pro forma as adjusted revenue for the
year ended December 31, 1997 from public sector contracts and funding. See
"Business -- Government Regulation."
 
     Competitive Bidding; Risks of Fixed Price Contracts.  Fixed price contracts
are typically awarded in the rail system services and products industry pursuant
to a competitive bidding process. In compiling its bid on a particular project,
each Founding Company must estimate the time it will take to complete the
project, along with the project's labor and supply costs. These costs may be
affected by a variety of factors, some of which may be beyond the Company's
control. If the Company is unable to predict accurately the costs of fixed price
contracts, certain projects could have lower margins than anticipated or the
Company could suffer a loss on a project, which could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     Reliance on Subcontractors and Suppliers.  The Company generally performs
its electrical contracting services for signaling and communication systems as a
subcontractor to companies which design the systems and manufacture or purchase
the necessary equipment. In other instances,
                                       11
<PAGE>   15
 
the Company acts as the prime contractor and subcontracts the design of the
signal or communication system and necessary equipment. When the Company is a
prime contractor for such projects, it generally requires subcontractors to post
performance bonds. The Company may not require a subcontractor to post a
performance bond in situations where (i) the subcontractor has strong experience
with a specific type of project and demonstrates financial stability and (ii)
the customer does not require bonds from the Company as prime contractor.
However, the Company is dependent upon the subcontractor to perform design and
other services and provide equipment. For certain projects there are a limited
number of companies which can perform the subcontract should the initial
subcontractor default. As a result, the Company is dependent upon its
subcontractors to perform under the subcontracts. Further, the major components
of electrical signaling and communication systems for transit authorities are
manufactured to specifications and require long lead times for production.
Should a subcontractor or supplier default, or should a supplier refuse to do
business with the Company, it could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     Bid and Performance Bonds.  Institutional and public works projects are
frequently long-term, complex projects requiring significant technical and
managerial skills and financial strength to, among other things, obtain bid and
performance bonds, which are often a condition to bidding for, and the awarding
of, contracts for such projects. There can be no assurance that the Company will
be able to obtain bid and performance bonds in the future, and the inability to
procure such bonds could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     Availability of Raw Materials.  Historically, the cost of both the lumber
used to produce wooden ties and steel has fluctuated significantly due to market
and industry conditions. Increasing demand for these raw materials may result in
cost increases, and there can be no assurance that the Company will be able to
recoup any such increases through price increases for its products. Further, a
reduction in supply of lumber or steel due to increased demand or other factors
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
     Labor Relations.  On a pro forma combined basis, as of March 31, 1998
approximately 67% of the Company's employees were covered under various
collective bargaining agreements. In June 1994, one of the Founding Companies
was affected by a strike by the United Brotherhood of Teamsters. There can be no
assurance that future work stoppages will not affect the Founding Companies. In
addition, labor agreements are generally negotiated on an industry-wide basis
and the determination of the terms and conditions of future labor agreements
could be beyond the Company's control. There can be no assurance that the
Company will not be subject to terms and conditions in future labor agreements
that could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Employees."
 
   
     Risks Related to Decentralized Operations.  The Company intends to conduct
business operations on a decentralized basis. In accordance with this
decentralized operating strategy, most of the senior managers of the individual
founding companies will remain at the Founding Company level. However, without
proper overall business controls, the Company's decentralized operating strategy
may result in inconsistent operating and financial practices at the Founding
Companies and subsequently acquired businesses. In such event, the Company's
business, financial condition and results of operations could be adversely
affected.
    
 
     Environmental Compliance and Government Regulation.  The Founding
Companies' operations are subject to extensive federal, state and local
regulation under environmental laws and regulations concerning, among other
things, emissions to the air, discharges to waters and the generation, handling,
storage, transportation, treatment and disposal of waste, hazardous substances,
underground and aboveground storage tanks and soil and groundwater
contamination. Environmental liability can extend to previously owned
properties, leased properties and properties owned by third parties, as well as
to properties currently owned and used by the Founding Companies.
 
                                       12
<PAGE>   16
 
Environmental liabilities can also arise from claims asserted by adjacent
landowners or other third parties in toxic tort litigation. The Company could
incur significant ongoing costs associated with environmental regulatory
compliance. Furthermore, certain of the Founding Companies use hazardous
materials in their own operations. Although the Company believes that the
Founding Companies are in material compliance with all of the various
regulations applicable to their businesses, there can be no assurance that
requirements will not change in the future or that the Company will not incur
significant costs to comply with such requirements.
 
     In addition to safety, health and other regulations of general
applicability, the operations of the Company may be significantly affected by
regulations of the Surface Transportation Board ("STB"), the Federal Railroad
Administration ("FRA"), the Occupational Safety and Health Administration
("OSHA"), state departments of transportation and other state and local
regulatory agencies. Changes in regulation of the rail and transit industries
through legislative, administrative, judicial or other action could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Government Regulation."
 
     Dependence on Key Personnel.  The Company believes that its success will
depend to a significant extent upon the efforts and abilities of John G. Larkin,
its Chairman of the Board and Chief Executive Officer, Michael R. Azarela, its
Executive Vice President and Chief Financial Officer, John Kennedy, its Vice
President and Chief Operating Officer, and Harold C. Kropp, Jr., its Vice
President and Chief Accounting Officer and, due to the Company's decentralized
operating strategy, senior management of the Founding Companies. While the
Company has entered into employment agreements with Messrs. Larkin, Azarela,
Kennedy, and Kropp and certain executive officers of each of the Founding
Companies will enter into employment agreements with their respective Founding
Companies in connection with the Combination, there can be no assurance that
such individuals will remain with the Company throughout the terms of their
agreements, or thereafter. The Company likely will depend on the senior
management of any significant business it acquires in the future. The loss of
the services of one or more of these key employees before the Company is able to
attract and retain qualified replacement personnel could have a material adverse
effect on the Company's business, financial condition and results of operation.
The Company does not maintain any life insurance policies on its executive
officers or senior management personnel. See "Management."
 
     Compensation Differential.  In connection with the Combination, certain
executive officers of each of the Founding Companies will enter into employment
agreements with their respective Founding Companies. The total compensation
packages to be paid under such agreements are considerably lower than those
historically received by certain owners of the Founding Companies in profitable
years. However, approximately 45% of the historical compensation of the owners
of the Founding Companies in 1997 was comprised of bonus compensation, often
tied to profitability. Following the initial two-year term of the employment
agreements, the Company will reevaluate its compensation structure after
examining operating results and the value of the services such individuals are
providing to the Company. To the extent that salaries following the initial term
are materially higher than those currently contemplated, the Company's business,
financial condition and results of operations could be adversely affected. See
"Management -- Employment Agreements."
 
   
     Substantial Proceeds of Offering to Benefit Affiliates.  At an assumed
initial public offering price of $12.00 per share, net proceeds of $55.8 million
from the Offering will be used to pay the cash portion of the purchase price for
the Founding Companies in the Combination and $3.9 million will be used to repay
outstanding indebtedness of certain of the Founding Companies (including
approximately $1.6 million of indebtedness incurred to partially finance the
redemption of shares of common stock of a Founding Company held by an ESOP). An
additional $32.5 million of indebtedness will be repaid with borrowings under
the Company's Credit Facility. Approximately $10.8 million of this indebtedness
has been guaranteed by, or is payable to, stockholders or affiliates of Founding
Companies. See "Formation of the Company -- The Combination."
    
                                       13
<PAGE>   17
 
     Potential Conflicts of Interest.  The Company is subject to risks
associated with potential conflicts of interest that may arise out of the
interrelationships among certain of the officers of the Founding Companies and
related third party entities with which the Founding Companies conduct business
transactions. For a detailed description of these and certain other related
party transactions, see "Certain Relationships and Related Party Transactions."
While the Company intends to conduct all related party transactions on terms no
less favorable than those the Company could negotiate with an unrelated third
party, the interests of officers of the Founding Companies in their capacities
with related third party entities may come into conflict with the interests of
such persons in their capacities with the Company.
 
   
     Potential Influence of Existing Stockholders.  After the Offering, the
Company's executive officers and directors will beneficially own an aggregate of
18.2% of the outstanding shares of Common Stock (16.9% if the Underwriters'
over-allotment option is exercised in full). The Company's executive officers
and directors if acting together may be able to substantially influence the
election of directors and matters requiring the approval of the stockholders of
the Company. This concentration of ownership may also have the effect of
delaying or preventing a change in control of the Company. See "Principal and
Selling Stockholders."
    
 
   
     Shares Eligible for Future Sale.  Upon completion of the Offering, the
Company will have 15,073,530 shares of Common Stock outstanding. The 5,000,000
shares sold in the Offering will be freely tradeable without restriction or
further registration under the Securities Act, unless acquired by an "affiliate"
of the Company, as that term is defined in Rule 144 promulgated under the
Securities Act ("Rule 144"). Shares held by affiliates will be subject to resale
limitations of Rule 144 described below. All of the remaining 10,073,530 shares
of Common Stock will be available for resale at various dates beginning 180 days
after the date of this Prospectus, upon expiration of applicable lock-up
agreements described below and subject to compliance with Rule 144 as the
holding provisions of Rule 144 are satisfied. In addition, 2,000,000 shares of
Common Stock are reserved for issuance pursuant to the Incentive Plan. The
Company intends to file a registration statement on Form S-8 as soon as
practicable after the consummation of the Offering with respect to the shares of
Common Stock issuable pursuant to the Incentive Plan. In addition, within (i) 90
days after the consummation of the Offering the Company intends to register
shares of Common Stock under the Securities Act for its use in connection with
future acquisitions and (ii) 180 days after the Offering the Company intends to
file a shelf registration statement to register up to 1.4 million shares of
Common Stock to permit sales of such shares by the Selling Stockholders and
IPODC.
    
 
     Sales of substantial amounts of Common Stock in the public market following
the Offering, or the perception that such sales could occur, could adversely
affect prevailing market prices of the Common Stock or the ability of the
Company to raise capital through sales of its equity securities. The Company has
agreed that it will not offer, sell or issue any shares of Common Stock or
options, rights or warrants to acquire any Common Stock for a period of 180 days
after the date of this Prospectus without the prior written consent of BT Alex.
Brown Incorporated, except for grants of options under the Incentive Plan and
shares issued (i) in connection with acquisitions and (ii) pursuant to the
exercise of options granted under the Incentive Plan. In addition, the Company's
directors and executive officers and the Selling Stockholders have agreed not to
directly or indirectly offer for sale, sell or otherwise dispose of any Common
Stock for a period of 180 days after the date of this Prospectus without the
prior written consent of BT Alex. Brown Incorporated, except for sales of Common
Stock by the Selling Stockholders upon the exercise of the Underwriters'
over-allotment option, if any. See "Underwriting." Further, the stockholders of
each of the Founding Companies have agreed with the Company that they will not
sell, pledge, transfer or otherwise dispose of any shares of Common Stock for a
period of one year from the date of the closing of the Combination.
 
     From the first anniversary of the consummation of the Offering to the
fourth anniversary of the consummation of the Offering the Company will make
available selling opportunities for the recipients of Common Stock in the
Combination to sell at various dates a certain number of shares of
 
                                       14
<PAGE>   18
 
Common Stock owned by them. Every quarter during the foregoing period, these
owners of Common Stock will be permitted to sell up to 8% of the Common Stock
received by them. If such owner does not sell such shares in a given quarter,
such owner may sell such shares in any later quarter, provided that in no event
may an owner sell more than 20% of the shares of Common Stock received by such
owner in any one quarter. The Company may elect to make available (i) additional
opportunities to sell shares of Common Stock and/or (ii) the opportunity to sell
an amount in excess of such amount in any particular quarter. Such sales will
take place either through block trades or registered offerings.
 
   
     No Prior Market for the Common Stock; Possible Volatility of Stock
Price.  Prior to the Offering, there has been no public market for the Company's
Common Stock. There can be no assurance that an active public market for the
Common Stock will develop or be sustained after the Offering or that purchasers
of Common Stock will be able to resell their Common Stock at prices equal to or
greater than the initial public offering price. The initial public offering
price of the Common Stock will be determined by negotiation between the Company
and the representatives of the Underwriters based on the factors described under
"Underwriting" and may not be indicative of the market price for the Common
Stock after the Offering.
    
 
     The trading price of the Common Stock could fluctuate in response to
various factors related to the Company, its competitors, the transportation
industry or the financial markets in general. Such factors include, but are not
limited to, quarterly operating results, changes in financial analysts'
recommendations or earnings estimates and changes in general or regional
economic conditions. Moreover, the stock market has experienced extreme price
and volume fluctuations in recent periods, which have not necessarily been
related to corporate operating performance. The volatility of the market could
adversely affect the market price of the Common Stock and the ability of the
Company to raise equity in the public markets. See "Underwriting."
 
   
     Dilution to New Investors.  After giving effect to the Combination,
purchasers of Common Stock in the Offering will experience immediate and
substantial dilution in the pro forma as adjusted net tangible book value of
their shares in the amount of $9.99 per share, or 83.3% assuming an initial
public offering price of $12.00 per share. See "Dilution." Within 90 days after
consummation of the Offering the Company intends to register additional shares
of Common Stock for issuance in future acquisitions. If the Company issues
additional shares of Common Stock in the future, including shares which may be
issued pursuant to the exercise of stock options and future acquisitions,
purchasers of Common Stock in the Offering may experience further dilution in
the net tangible book value per share of the Common Stock.
    
 
     Certain Antitakeover Provisions.  Certain provisions of the Company's
Restated Certificate of Incorporation (the "Certificate of Incorporation") and
Bylaws and Delaware law may make a change in the control of the Company more
difficult to effect, even if a change in control were in the stockholders'
interest. The Company is subject to the anti-takeover provisions of Section 203
of the Delaware General Corporation Law (the "DGCL"), which prohibit the Company
from engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an "interested stockholder," unless the business combination is approved
in a prescribed manner. In addition, the Company's Certificate of Incorporation
and Bylaws provide for a nine member Board of Directors to be elected to
staggered one-, two- and three- year terms and, thereafter, for successive
three-year terms. Additionally, the Certificate of Incorporation provides that
the Company may issue up to 10,000,000 shares of preferred stock with rights and
preferences determined by the Board of Directors. Such issuance may make it more
difficult for a third party to obtain a majority of the Company's outstanding
stock. See "Description of Capital Stock -- Certain Provisions of Delaware Law
and the Company's Certificate of Incorporation and Bylaws."

                            FORMATION OF THE COMPANY
 
INCORPORATION
 
     RailWorks Corporation was incorporated in Delaware in March 1998 as a
holding company to acquire companies that provide rail system services,
including construction and rehabilitation, repair and maintenance, and related
products. Prior to the Combination and the Offering, RailWorks Corporation
issued shares of Common Stock for cash to John G. Larkin, the Chairman of the
Board and Chief Executive Officer of the Company, in connection with its
incorporation. See "Certain Relationships and Related Party
Transactions -- Organization of RailWorks Corporation."
 
THE COMBINATION
 
   
     Simultaneously with and as a condition to the closing of the Offering,
RailWorks Corporation will acquire in separate transactions all of the issued
and outstanding capital stock of each of the Founding Companies for an aggregate
consideration (assuming an initial public offering price of $12.00 per share) of
$158.3 million (subject to adjustment), which consists of (i) $51.9 million in
cash, which will be paid from the proceeds of the Offering (representing 92.9%
of the estimated net proceeds of the Offering) and (ii) the $106.4 million fair
value of 8,867,648 shares of Common Stock to be issued to the stockholders of
the Founding Companies. In addition, in connection with the Combination, the
Company will assume $35.0 million of indebtedness of certain of the Founding
Companies (including approximately $1.6 million of indebtedness incurred to
partially finance the redemption of shares of common stock of a Founding Company
held by an ESOP). Such indebtedness will be repaid with a portion of the
proceeds of the Offering (representing 7.1% of the estimated net proceeds of the
Offering) and with borrowings under the Company's Credit Facility. The purchase
price for each Founding Company was determined based on negotiations between
RailWorks Corporation and the Founding Companies. The factors considered by the
parties in determining the purchase price were historical operating results,
growth rates and assets and liabilities of the Founding Companies, and such
factors were applied consistently to each Founding Company. The following table
contains information concerning the aggregate cash to be paid and Common Stock
expected to be issued (at an assumed initial public offering price of $12.00 per
share) in connection with the Combination (subject to adjustment):

(1) Fees to be paid to IPODC on behalf of the Founding Companies are set forth
    separately in the table and are excluded from the amounts set forth for the
    Founding Companies.
    
(2) Excludes assumed indebtedness.
(3) Includes Mize Construction Company, Railroad Specialities, Inc. and U.S.
    Railway Supply Inc., all of which are under common control.
   
(4) Includes approximately $1.6 million of indebtedness incurred to partially
    finance the redemption of shares of common stock of a Founding Company held
    by an ESOP.
    
(5) Includes Alpha-Keystone Engineering, Inc. and Railcorp, Inc., all of which
    are under common control.
(6) Includes Minnesota Railroad Service, Inc., which is under common control.
(7) Includes Northern Rail Service and Supply Co., which is under common
    control.
(8) Includes Wm. A. Smith Rerailing Service, Inc., which is under common
    control.
   
(9) In exchange for services provided by IPODC, the Founding Companies have
    agreed to pay IPODC a fee equal to 3 1/2% of the total consideration paid to
    the Founding Companies (excluding the cash portion of Comstock's
    consideration) in the Combination. Such fee will be paid in cash and shares
    of Common Stock in the amounts reflected in the table. See "-- Organizer."
    
 
   
     The consummation of each Acquisition is contingent upon the consummation of
the Offering and the satisfaction of customary closing conditions, including the
absence of any material adverse change in the business, operations and financial
condition of the Founding Companies and certification by the parties to each
Acquisition Agreement that the representations and warranties made by such party
in the Acquisition Agreement are true and correct as of the consummation of the
Acquisition and that such party has performed its obligations under the
Acquisition Agreement. Each Acquisition is subject to substantially the same
terms and conditions. The Acquisition Agreements provide that the stockholders
of the Founding Companies will indemnify RailWorks from certain liabilities that
may arise in connection with the Combination. The Acquisition Agreements require
certain executive officers of each of the Founding Companies to enter into
employment agreements with their respective Founding Companies effective upon
consummation of the Combination. In addition, executive officers of certain of
the Founding Companies will be elected to the Board of Directors of the Company
following the consummation of the Offering. After the Offering, the stockholders
of the Founding Companies, management of the Company and IPODC will in the
aggregate own 66.8% of the outstanding Common Stock, assuming the Underwriters'
over-allotment option is not exercised.
    
 
ORGANIZER
 
   
     The Company was organized by IPODC, which was not previously affiliated
with any of the Founding Companies. IPODC identified the Founding Companies,
arranged for the Company's retention of its executive officers and managed the
initial organizational stages of the Combination and the Offering. In exchange
for the services provided by IPODC, the Founding Companies have agreed to pay
IPODC or its designees upon the completion of the Combination and the Offering,
a fee equal to 3 1/2% of the total consideration paid to the Founding Companies
in the Combination (excluding Comstock's cash consideration). Such fee will be
paid out of the cash and shares of Common Stock to be received by the Founding
Companies.

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the shares of Common Stock
offered by it hereby (at an assumed initial public offering price of $12.00 per
share), after deducting estimated underwriting discounts and commissions payable
by the Company, are $55.8 million. Of such net proceeds, the Company intends to
use (i) $51.9 million to pay the cash portion of the aggregate purchase price
for the Founding Companies in the Combination and (ii) $3.9 million to repay a
portion of the indebtedness of certain of the Founding Companies (including $1.6
million of indebtedness incurred to partially finance the redemption of shares
of common stock of a Founding Company held by an ESOP). The expenses of the
Offering incurred by the Company and the remaining indebtedness of the Founding
Companies will be paid from the Credit Facility and cash on hand. See "Formation
of the Company -- The Combination" and "Certain Relationships and Related Party
Transactions -- The Combination."
    
 
     The Company will not receive any proceeds from the sale of shares of Common
Stock to be sold by the Selling Stockholders.
 
                                DIVIDEND POLICY
 
     The Company does not anticipate paying any cash dividends on its Common
Stock in the foreseeable future because it intends to retain any earnings to
finance the expansion of its business and for general corporate purposes. Any
payment of future dividends will be at the discretion of the Board of Directors
of the Company and will depend upon, among other factors, the Company's
earnings, financial condition, capital requirements, level of indebtedness,
contractual restrictions with respect to the payment of dividends and other
considerations that the Company's Board of Directors deems relevant.

                                    DILUTION
 
   
     At March 31, 1998, the Company had a deficit in pro forma combined net
tangible book value of $23.3 million, or $2.31 per share of Common Stock. Pro
forma combined net tangible book value per share is determined by dividing the
pro forma combined net tangible book value of the Company (tangible assets less
liabilities) by the number of shares of Common Stock outstanding prior to the
Offering. Adjusting for the sale by the Company of 5,000,000 shares of Common
Stock offered hereby (at an assumed initial public offering price of $12.00 per
share) and the application of the estimated net proceeds therefrom as described
under "Use of Proceeds," the pro forma as adjusted net tangible book value of
the Company at March 31, 1998 would have been $30.3 million, or $2.01 per share.
This represents an immediate dilution in pro forma as adjusted net tangible book
value to new investors of $9.99 per share, or 83.3%, and an immediate increase
in pro forma as adjusted net tangible book value to existing stockholders of
$4.32 per share. The following table illustrates this per share dilution to new
investors:

                 SELECTED PRO FORMA AS ADJUSTED FINANCIAL DATA
 
   
     RailWorks Corporation was formed in March 1998 to acquire the Founding
Companies simultaneously with and as a condition to the consummation of the
Offering. For accounting and financial statement purposes, Comstock has been
identified as the accounting acquiror consistent with SAB No. 97 of the
Commission because its owners will receive the largest portion (32.8%) of the
shares of Common Stock issued to the owners of the Founding Companies in the
Combination. The acquisitions of the remaining Founding Companies will be
accounted for as purchases in accordance with APB No. 16. The selected pro forma
as adjusted data are not necessarily indicative of the operating results or
financial position that would have been achieved had the Combination and
Offering been consummated and should not be construed as representative of the
Company's future operating results or financial position. The selected pro forma
as adjusted financial data should be read in conjunction with "Management's
Discussion and Analysis of Financial Condition and Results of Operations," the
Unaudited Pro Forma As Adjusted Financial Statements and the notes thereto and
the historical financial statements of the Founding Companies and the notes
thereto included elsewhere in this Prospectus. The Company anticipates that
following the Combination it will realize savings from: (i) more efficient
utilization of equipment and the Company's workforce; (ii) the combination of
administrative functions such as accounting, finance and human resources and
certain other functions at the corporate level; (iii) better pricing on
purchases of equipment and supplies; and, to a lesser extent, (iv) joint bidding
on larger rail projects. Those savings, which cannot be quantified or reasonably
estimated, have not been reflected in the Unaudited Pro Forma As Adjusted
Financial Statements or in the selected data presented below.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
   
     RailWorks Corporation was formed in March 1998 to become a leading
nationwide provider of rail system services, including construction and
rehabilitation, repair and maintenance, and related products. The Company
primarily performs services pursuant to contracts for the completion of specific
projects, some of which take up to five years to complete. On most projects, the
Company contracts directly with rail system operators, while on other projects
the Company acts as a subcontractor. RailWorks Corporation, which has conducted
no operations to date, has entered into agreements to acquire the Founding
Companies simultaneously with the consummation of the Offering. In 1997, on a
pro forma as adjusted basis, the Company had revenue of $256.5 million,
operating income of $11.2 million and net income of $5.4 million. For the three
months ended March 31, 1998, on a pro forma as adjusted basis, the Company had
revenue of $61.8 million, operating income of $1.5 million and net income of
$655,000.
    
 
     While the Company intends to conduct the operations of the Founding
Companies on a decentralized basis, the Company will integrate certain aspects
of its operations, such as administrative functions, in order to achieve
potential cost savings through the elimination of duplicative functions. Such
integration may also necessitate additional costs and expenditures for corporate
management and administration, systems integration, employee relocation and
severance and facilities expansion. The Company does not anticipate any material
reduction in its workforce to result from this integration. As a result of these
various additional costs and potential cost savings, comparison of future
operating results with historical operating results may not be meaningful.
 
     In addition, the Founding Companies have operated historically under
varying tax structures, including both S and C Corporations, which have
influenced the historical level of owners' compensation. As a result of varying
practices regarding employee-stockholder compensation among the Founding
Companies, comparison of operating results among the Founding Companies and from
period to period in respect of a particular Founding Company may not be
meaningful. Upon consummation of the Combination, certain executive officers of
each of the Founding Companies will enter into employment agreements with their
respective Founding Companies. The aggregate compensation to be paid to such
executive officers will be reduced as reflected in the Unaudited Pro Forma As
Adjusted Statements of Income included elsewhere in this Prospectus. Following
the initial two-year term of the employment agreements, the Company will
reevaluate its compensation structure after examining operating results and the
value of the services such individuals are providing the Company. See "Risk
Factors -- Compensation Differential."
 
REVENUE AND COSTS
 
     The Company recognizes revenues from fixed price contracts using the
percentage-of-completion method, measured by the percentage of costs incurred to
date to management's estimated total cost for each contract. Changes in job
performance, job conditions and estimated profitability may result in revisions
to cost and income, which are recognized in the period in which the revisions
are determined. Revenues from time-and-material contracts are recognized
currently as the work is performed.
 
     Contract costs consist principally of wages and benefits of employees,
subcontracted services, materials, parts and supplies, depreciation, fuel and
other vehicle expenses and equipment rental, as well as indirect costs related
to contract performance. Contract costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted contracts are made in the period
in which such losses are determined.
 
                                       26
<PAGE>   30
 
     In the case of product sales, the Company recognizes revenue when products
are delivered to customers pursuant to shipping agreements. Cost of goods sold
includes raw materials cost and production cost.
 
     The Company's gross margin for a project depends on the relative proportion
of costs related to labor and materials and on whether the Company functions as
a prime contractor or as a subcontractor. The Company generally realizes higher
gross margins on projects in which it functions as a prime contractor. A
significant portion of the Company's revenue is attributable to materials and
supplies installed in connection with its contracting activities. Costs of
materials and supplies are typically passed through to the customer and revenue
from these items has a significantly lower profit margin than revenue related to
other activities. For projects in which a higher percentage of the contract
costs consists of labor, the Company's bid price includes a higher gross margin
than for projects in which materials represent more of the contract costs due to
the greater difficulty in estimating the required labor. Material costs can be
estimated with greater accuracy and prices often can be fixed by placing orders
at the time a project is bid or commenced.
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
     The Founding Companies have in the past experienced quarterly variations in
revenue, operating income (including operating losses), net income (including
net losses) and cash flows (including cash flow deficits) as a result of various
factors, including projects commenced and completed during a quarter, the number
of business days in a quarter and the size and scope of projects. A variation in
the number of projects, progress on projects or the timing of the initiation or
completion of projects can cause periods in which certain operating resources
are not generating revenue and can cause significant variations in operating
results between reporting periods. Negative fluctuations have been particularly
pronounced, and net losses have been incurred, in the first and fourth calendar
quarters, generally due to adverse weather conditions. The Company expects to
continue to experience such quarterly fluctuations in operating results,
including possible net losses. See "Risk Factors -- Rail System Cyclicality" and
"-- History of Losses; Fluctuations in Quarterly Operating Results."
 
PRO FORMA AS ADJUSTED RESULTS OF OPERATIONS
 
     The pro forma as adjusted results of operations of the Company for the
periods presented may not be comparable to, and may not be indicative of, the
Company's post-Combination results of operations because (i) the Founding
Companies were not under common control or management during the periods
presented and (ii) the pro forma as adjusted data do not reflect all of the
potential benefits and cost savings the Company expects to realize as a result
of operating as a combined entity. The following discussion should be read in
conjunction with the Unaudited Pro Forma As Adjusted Financial Statements and
the related notes thereto and the historical financial statements of the
Founding Companies and the related notes appearing elsewhere in this Prospectus.

decreased to 11.6% for the three months ended March 31, 1998 from 13.4% for the
three months ended March 31, 1997. The decline in gross profit as a percentage
of revenue was the result of the completion of several large contracts with
unusually high margins which were in process during the three months ended March
31, 1997. See "-- Quarterly Fluctuations in Results of Operations."
 
     General and Administrative Expenses.  General and administrative expenses
decreased to $5.1 million for the three months ended March 31, 1998 from $5.5
million for the three months ended March 31, 1997, a decrease of $447,000 or
8.1%. This decrease was the result of improved workers' compensation claims
experience and reduced costs at Comstock due to cost reductions implemented
following its acquisition from Spie (as described below). As a percentage of
revenue, general and administrative expenses decreased to 8.2% for the three
months ended March 31, 1998 from 10.4% for the three months ended March 31,
1997. The decline in general and administrative expenses as a percentage of
revenue was principally the result of leveraging general and administrative
expenses over a higher sales volume.
 
     Net Income.  Net income increased to $749,000 for the three months ended
March 31, 1998 from $600,000 for the three months ended March 31, 1997, an
increase of $149,000 or 24.8%. As a percentage of revenue, net income increased
to 1.2% for the three months ended March 31, 1998 from 1.1% for the three months
ended March 31, 1997.
 
PRO FORMA AS ADJUSTED LIQUIDITY AND CAPITAL RESOURCES
 
     The Company expects capital expenditures of approximately $1.0 million and
$3.0 million in 1998 and 1999, respectively, primarily to support expansion of
its management information systems.
 
   
     Cash for future acquisitions and working capital will be financed by funds
generated from operations, together with borrowings under a three-year, $75.0
million senior revolving credit facility (the "Credit Facility") which
NationsBank, N.A. ("NationsBank") has committed to extend upon consummation of
the Offering and the satisfaction of certain customary closing conditions. Upon
consummation of the Offering the Company intends to draw down the Credit
Facility by $31.0 million to repay the indebtedness of the Founding Companies
that is not repaid with the proceeds of the Offering. Availability of borrowings
will be subject to a borrowing base formula that initially will limit borrowings
to approximately $35 million. The Credit Facility will be secured by a first
lien on all of the capital stock of the Company's subsidiaries and on all
accounts receivable of the Company and its subsidiaries. The credit agreement
(the "Credit Agreement") governing the Credit Facility
    
 
                                       28
<PAGE>   32
 
   
will contain a negative pledge on all other assets of the Company and its
subsidiaries and other usual and customary covenants and events of default for
transactions of the type contemplated by the Credit Facility. Borrowings under
the Credit Facility will bear interest, at the option of the Company, at an
interest rate equal to (i) LIBOR plus the applicable margin for LIBOR loans,
which ranges from 125 basis points to 250 basis points based on the ratio of
Funded Debt to EBITDA (as such terms will be defined in the Credit Agreement) or
(ii) the Alternate Base Rate (defined as the higher of (a) the NationsBank prime
rate and (b) the Federal Funds rate plus 50 basis points) plus up to 125 basis
points based on the ratio of Funded Debt to EBITDA. The Company may also finance
future acquisitions with shares of Common Stock.
    
 
RESULTS OF OPERATIONS OF THE FOUNDING COMPANIES
 
   
     Prior to the Combination, the Founding Companies (other than affiliates of
Annex Railroad Builders, Inc., Comstock Holdings, Inc., CPI Concrete Products
Incorporated, H.P. McGinley, Incorporated, Kennedy Railroad Builders, Inc., New
England Railroad Construction Company, Inc., and Wm. A. Smith Construction Co.,
Inc.) elected to be treated as S Corporations for federal income tax purposes.
As a result, these S Corporations were not subject to federal income taxes. The
selling, general and administrative expenses of the Founding Companies include
compensation to employee-stockholders of the Founding Companies for the years
ended December 31, 1996 and 1997 and the three months ended March 31, 1998. Upon
consummation of the Combination, certain executive officers of each of the
Founding Companies will enter into employment agreements with their respective
Founding Companies. The aggregate compensation to be paid to such executive
officers will be reduced as reflected in the Unaudited Pro Forma As Adjusted
Statements of Income included elsewhere in this Prospectus. Following the
initial two-year term of the employment agreements, the Company will reevaluate
its compensation structure after examining operating results and the value of
the services such individuals are providing the Company. See "Risk
Factors -- Compensation Differential." As a result of varying practices
regarding compensation to employee-stockholders among the Founding Companies,
the comparison of operating margins among the Founding Companies and from period
to period in respect of a particular Founding Company may not be meaningful.
    
 
     The following information describes the results of operations for certain
of the Founding Companies.
 
COMSTOCK HOLDINGS, INC.
 
   
     Founded in 1904, L.K. Comstock & Co., Inc. ("L.K. Comstock"), a
wholly-owned subsidiary of Comstock, is one of the largest electrical
contractors in the United States based on revenue. L.K. Comstock specializes in
power, communication and signaling installations for rail-based transit systems
and also provides electrical contracting services for commercial buildings,
heavy industrial and manufacturing plants and power plants. Through incremental
investments from 1986 through 1989, L.K. Comstock's former parent company,
Comstock Group, Inc. ("CGI"), was acquired by Spie Enertrans S.A. ("Spie"), a
multinational electrical engineering firm headquartered in Paris, France. During
Spie's ownership, L.K. Comstock sought to increase revenue by expanding its non-
transit operations in California and entering into joint ventures to design and
build large power and industrial projects in other locations. Effective January
1, 1997, L.K. Comstock was acquired (the "Comstock Acquisition") from Spie by
Comstock, a corporation owned by certain employees of L.K. Comstock. Comstock's
revenue in fiscal 1997 was $153.6 million, representing 59.9% of the Company's
pro forma as adjusted revenue for 1997.
    
 
     Following the Comstock Acquisition, Comstock's management instituted a plan
to reduce Comstock's costs and improve profitability. As a result of this plan,
Comstock has reduced general and administrative expenses by eliminating certain
management positions, including those of
 
                                       29
<PAGE>   33
 
several French expatriates, and reducing its Los Angeles-based staff. Comstock
has also been improving gross profit margins through (i) improved control over
contract costs by consolidating transit project estimating and bidding functions
and (ii) exiting unprofitable, risky operations which had been expanded under
Spie's ownership (such as electrical projects for traffic systems, non-rail
projects in California and large joint ventures for the design and construction
of power and industrial plants). Under joint ventures with general construction
contractors, as preferred by Spie, Comstock had limited management control and
was subject to increased costs due to general contract conditions. Following the
Comstock Acquisition, management has focused the business to benefit from its
core competencies, including rail-based transit projects. However, Comstock's
electricians and supervisors are capable of performing services on rail and
non-rail projects, thus enabling the efficient use of experienced labor on
projects in response to demand. Additionally, its accounting and management
systems are designed to provide necessary information for both rail and non-rail
projects. In 1997, Comstock derived 56.7% of its revenue and 58.6% of its gross
profit from rail-related projects as compared to 48.1% and 48.5%, respectively,
in 1996.
 
     The following table sets forth certain selected financial data and data as
a percentage of revenue for the periods indicated.

</TABLE>
 
 Three Months Ended March 31, 1998 Compared to Three Months Ended March 31, 1997
 
     Revenue.  Revenue increased to $41.6 million for the three months ended
March 31, 1998 from $32.4 million for the three months ended March 31, 1997, an
increase of $9.2 million, or 28.5%. This increase was a result of a $12.3
million increase in revenue from commercial and other operations due to the
commencement of work on certain large projects, including those at John F.
Kennedy International Airport in New York ("JFK").
 
     Gross Profit.  Gross profit remained stable at $4.4 million for the three
months ended March 31, 1998 and 1997. As a percentage of revenue, gross profit
decreased to 10.6% for the three months ended March 31, 1998 from 13.6% for the
three months ended March 31, 1997. This decrease was the result of costs
associated with the JFK projects.
 
     General and Administrative Expenses.  General and administrative expenses
decreased to $3.2 million for the three months ended March 31, 1998 from $3.9
million for the three months ended March 31, 1997, a decrease of $671,000, or
17.2%. As a percentage of revenue, general and administrative expenses decreased
to 7.7% for the three months ended March 31, 1998 from 12.0% for the three
months ended March 31, 1997. This decline was a result of reductions in
executive and administrative staff and tighter cost controls by management.
 
     Net Income.  Net income increased to $666,000 for the three months ended
March 31, 1998 from $440,000 for the three months ended March 31, 1997, an
increase of $226,000, or 51.4%. As a percentage of revenue, net income increased
to 1.6% for the three months ended March 31, 1998 from 1.4% for the three months
ended March 31, 1997. The increase in net income was primarily due to the
reduction in general and administrative expenses described above and a decrease
in interest expense due to lower average borrowings.

<PAGE>   34
 
  Year Ended December 31, 1997 Compared to Year Ended December 31, 1996
 
     Revenue.  Revenue decreased to $153.6 million for the year ended December
31, 1997 from $188.8 million for the year ended December 31, 1996, a decrease of
$35.2 million, or 18.6%. This decrease was due to a decrease in revenue from
Comstock's power and industrial operations attributable to the completion of
certain large projects in 1996 and early 1997 that were not immediately
replaced, as well as a decrease in revenue from Comstock's traffic operations,
offset in part by an increase in revenue from Comstock's commercial operations.
The decrease in revenue from traffic operations, as well as a portion of the
decrease in revenue from power and industrial operations, were due to the change
in strategic focus discussed above and it is unlikely that such projects will be
replaced. Rail-related revenue did not change significantly from 1996 to 1997
due to limited bonding capacity.
 
     Gross Profit.  Gross profit decreased to $16.9 million for the year ended
December 31, 1997 from $19.5 million for the year ended December 31, 1996, a
decrease of $2.5 million, or 13.0%. As a percentage of revenue, gross profit
increased to 11.0% for the year ended December 31, 1997 from 10.3% for the year
ended December 31, 1996. Gross profit decreased as a result of the decline in
revenue, offset in part by tighter cost controls implemented by management and a
reduction in the amount of activity in traffic and Los Angeles-based non-rail
projects which had significantly lower margins. Additionally, 1996 gross profit
benefitted from a reduction in contract reserves of approximately $3 million
related to the settlement of outstanding project contingencies. See "Certain
Transactions and Related Party Transactions -- Other Transactions."
 
     General and Administrative Expenses.  General and administrative expenses
decreased to $13.7 million for the year ended December 31, 1997 from $15.1
million for the year ended December 31, 1996, a decrease of $1.3 million, or
8.8%. This decrease was a result of the tighter cost controls implemented by
management, including reductions in executive and administrative staff in the
power, industrial and Los Angeles-based non-rail operations. As a percentage of
revenue, general and administrative expenses increased to 8.9% for the year
ended December 31, 1997 from 8.0% for the year ended December 31, 1996. This
increase was the result of the decrease in revenue.
 
     Net Income.  Net income increased to $1.4 million for the year ended
December 31, 1997 from $58,000 for the year ended December 31, 1996, an increase
of $1.4 million. For each period, net income as a percentage of revenue was less
than 1%. The increase in net income was partially due to the reduction of
general and administrative expenses discussed above and the elimination of
management expenses of $941,000 paid to Spie and related entities in 1996. In
addition, as a result of the Comstock Acquisition and the related purchase
accounting, approximately $1.5 million of depreciation and amortization were
eliminated in 1997 as compared to 1996. These factors which increased net income
were partially offset by the decrease in gross profit due to the factors
discussed above.
 
  Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
     Revenue.  Revenue increased to $188.8 million for the year ended December
31, 1996 from $181.6 million for the year ended December 31, 1995, an increase
of $7.2 million, or 3.9%. This increase was due to a $22.1 million increase in
revenue from Comstock's rail-related operations, resulting from the commencement
of several projects in the metropolitan New York area, partially offset by a
reduction of approximately $13 million in revenue from Comstock's commercial and
other operations due to the completion of several projects in 1995 or early 1996
that were not immediately replaced.
 
     Gross Profit.  Gross profit increased to $19.5 million for the year ended
December 31, 1996 from $16.8 million for the year ended December 31, 1995, an
increase of $2.6 million, or 15.6%. As a percentage of revenue, gross profit
increased to 10.3% for the year ended December 31, 1996 from 9.3% for the year
ended December 31, 1995. Gross profit increased principally as a result of a
reduction in contract reserves of approximately $3 million related to the
settlement of outstanding
                                       31
<PAGE>   35
 
project contingencies (see "Certain Transactions and Related Party
Transactions -- Other Transactions") and, to a lesser extent, increased revenue.
 
     General and Administrative Expenses.  General and administrative expenses
decreased to $15.1 million for the year ended December 31, 1996 from $15.6
million for the year ended December 31, 1995, a decrease of $571,000, or 3.7%.
As a percentage of revenue, general and administrative expenses decreased to
8.0% for the year ended December 31, 1996 from 8.6% for the year ended December
31, 1995. This decrease was primarily the result of a reduction in
administrative staff and expenses at Comstock's Los Angeles office.
 
     Net Income (Loss).  Net income increased to $58,000 from a net loss of
$20.0 million for the year ended December 31, 1995, an improvement of $20.0
million. The improvement in net income was primarily due to a charge of $20.1
million incurred in 1995 for the impairment of long-lived assets and the
increase in gross profit due to the factors discussed above. These factors were
partially offset by an increase in interest expense of $1.2 million due to
higher average borrowings.
 
LIQUIDITY AND CAPITAL RESOURCES OF COMSTOCK HOLDINGS, INC.
 
     At March 31, 1998, Comstock had cash and cash equivalents of $945,000 and
working capital of $25.6 million. For the three months ended March 31, 1998,
cash flow from operations was $1.5 million which was principally used to reduce
the outstanding balance on Comstock's credit line described below.
 
     At December 31, 1997, Comstock had cash and cash equivalents of $1.1
million and working capital of $26.5 million. For the year ended December 31,
1997, Comstock had a cash flow deficit from operations of $3.2 million primarily
due to the commencement of certain new rail-related projects which increased the
unbilled accounts receivable. In connection with the Comstock Acquisition, L.K.
Comstock received $14.9 million in cash from Spie and issued a contingent
promissory note for such amount. See "Certain Transactions and Related Party
Transactions -- Other Transactions." The proceeds of the contingent promissory
note were used primarily to reduce long-term borrowings.
 
   
     L.K. Comstock has a $17.0 million revolving credit line pursuant to two
separate agreements with Harris Trust and Savings Bank. Borrowings bear interest
at either 1% over the prime rate or 3.25% over LIBOR. These borrowings are
secured by substantially all of the assets of L.K. Comstock and are subject to
various financial covenants. Comstock, and to a limited extent, certain members
of Comstock's management, have guaranteed a portion of the borrowings. The total
amount of borrowings including letters of credit outstanding under these credit
lines was $15.0 million at March 31, 1998. After the closing of the Offering,
RailWorks will assume the obligations under the credit line and repay all
outstanding borrowings. See "Use of Proceeds."
    
 
     During the remainder of 1998, Comstock is obligated to make aggregate
payments of $750,000, together with interest accruing at 8.5% per annum, in full
satisfaction of a note to BW Capital. RailWorks will assume this obligation and
repay the amount outstanding. In the first quarter of 1998, Comstock made
payments of $950,000 on such note.
 
     The contracts under which Comstock performs services generally require
retainage ranging from 2% to 10% of the total contract price until the project
is complete. At March 31, 1998, $14.6 million of Comstock's accounts receivable
consisted of retainage. In some instances, the terms of the contract allow
Comstock to replace the amount withheld with certain marketable securities, such
as treasury bonds, and retain the yield on such investments. At March 31, 1998,
$4.9 million of Comstock's retainage was invested in marketable securities.
Comstock estimates that $7.3 million of this retainage will be collected by
March 31, 1999.
 
     Prior to the Comstock Acquisition, Comstock maintained a deductible of
$250,000 per incident on its auto and general liability insurance policies. At
December 31, 1997, Comstock carried a $3.6 million liability on its balance
sheet as a reserve against these liabilities. Currently, Comstock
                                       32
<PAGE>   36
 
maintains considerably lower deductibles on its insurance policies to provide
greater predictability and consistency in insurance and liability costs.
 
ANNEX RAILROAD BUILDERS, INC. AND AFFILIATES
 
     Founded in 1961, Annex Railroad Builders, Inc. and its affiliates ("Annex")
provide construction, rehabilitation, repair and maintenance services for
railroad track in the Midwestern and Southern United States. In calender year
1997, Annex estimates that it derived approximately 69% of its revenue from
maintenance and repair and 31% of its revenue from new construction and
rehabilitation. Annex's revenue in calendar year 1997 was $19.1 million,
representing 7.4% of the Company's pro forma as adjusted revenue for 1997.
 
     The following table sets forth certain selected combined financial data and
data as a percentage of revenue for the periods indicated.

  Three Months Ended March 31, 1998 Compared to Three Months Ended March 31,
1997
 
     Revenue.  Revenue decreased to $2.9 million for the three months ended
March 31, 1998 from $5.3 million for the three months ended March 31, 1997, a
decrease of $2.4 million, or 44.7%, primarily as a result of two large
government projects that were completed in 1997.
 
     Gross Profit.  Gross profit decreased to $643,000 for the three months
ended March 31, 1998 from $774,000 for the three months ended March 31, 1997, a
decrease of $131,000, or 16.9%. As a percentage of revenue, gross profit
increased to 22.0% for the three months ended March 31, 1998 from 14.6% for the
three months ended March 31, 1997. Gross profit decreased as a result of the
decline in revenue. Despite the decrease in gross profit, gross profit as a
percentage of revenue increased due to an improvement in the types of jobs
performed.
 
     General and Administrative Expenses.  General and administrative expenses
decreased to $370,000 for the three months ended March 31, 1998 from $453,000
for the three months ended March 31, 1997, a decrease of $82,000, or 18.3%. As a
percentage of revenue, general and administrative expenses increased to 12.7%
for the three months ended March 31, 1998 from 8.6% for the three months ended
March 31, 1997. Despite the decrease in salaries and wages that caused the
decline in general and administrative expenses, general and administrative
expenses as a percentage of revenue increased due to significant fixed general
and administrative expenses that did not decrease with the lower revenue.
 
     Net Income.  Net income remained relatively stable at $218,000 for the
three months ended March 31, 1998 and $206,000 for the three months ended March
31, 1997. As a percentage of revenue, net income increased to 7.5% for the three
months ended March 31, 1998 from 3.9% for the three months ended March 31, 1997.
The increase in net income as a percentage of revenue resulted from the decrease
in revenue, offset in part by the decrease in general and administrative
expenses, as described above.

  Nine Months Ended December 31, 1997 Compared to Year Ended March 31, 1997
 
     Because Annex changed its fiscal year end in 1997 from March 31 to December
31, the period ended December 31, 1997 is a nine-month period as compared to a
twelve-month period for the year ended March 31, 1997.
 
   
     Revenue.  Revenue was $15.1 million for the nine months ended December 31,
1997 and $15.5 million for the year ended March 31, 1997. Revenue increased to
$18.0 million for the twelve-month period ended March 31, 1998 from $15.5
million in the year ended March 31, 1997, an increase of $2.5 million, or 16.5%.
This increase was attributable to an increase in the number of contracts in
process due to strong demand for government projects.
    
 
     Gross Profit.  Gross profit was $2.7 million for the nine months ended
December 31, 1997 and $2.5 million for the year ended March 31, 1997. Gross
profit increased to $3.3 million for the twelve-month period ended March 31,
1998 from $2.5 million for the year ended March 31, 1997, an increase of
$817,000, or 32.4%. As a percentage of revenue, gross profit increased to 18.5%
for the twelve-month period ended March 31, 1998 from 16.3% for the year ended
March 31, 1997. Gross profit increased principally as a result of higher margin
contracts which generated higher revenue with a less than proportional increase
in cost.
 
     General and Administrative Expenses.  General and administrative expenses
were $1.3 million for the nine months ended December 31, 1997 and $1.7 million
for the year ended March 31, 1997. General and administrative expenses remained
relatively stable at $1.7 million for the twelve-month period ended March 31,
1998 and for the year ended March 31, 1997. As a percentage of revenue, general
and administrative expenses decreased to 9.4% for the twelve-month period ended
March 31, 1998 from 10.8% for the year ended March 31, 1997. This decrease was
the result of relatively stable expenses despite the increase in revenue.
 
     Net Income.  Net income was $970,000 for the nine months ended December 31,
1997 and $599,000 for the year ended March 31, 1997. Net income increased to
$1.2 million for the twelve-month period ended March 31, 1998 from $599,000 for
the year ended March 31, 1997, an increase of $589,000, or 98.3%. As a
percentage of revenue, net income increased to 6.6% for the twelve-month period
ended March 31, 1998 from 3.9% for the year ended March 31, 1997. The increase
in net income was the result of the increase in gross profit discussed above.

months ended March 31, 1997.
 
  Nine Months Ended December 31, 1997 Compared to Year Ended March 31, 1997
 
     Because Kennedy, Alpha-Keystone and Railcorp changed their fiscal year ends
from March 31 to December 31 in 1997, the period ended December 31, 1997 is a
nine-month period as compared to a twelve-month period for the year ended March
31, 1997.
 
     Revenue.  Revenue was $8.3 million for the nine months ended December 31,
1997 and $9.7 million for the year ended March 31, 1997. Revenue increased to
$10.7 million for the twelve-month period ended March 31, 1998 from $9.7 million
for the year ended March 31, 1997, an increase of $1.0 million, or 10.1%. This
increase was the result of an increase in the number of construction projects in
process during the twelve months ended March 31, 1998.
 
     Gross Profit.  Gross profit was $1.7 million for the nine months ended
December 31, 1997 and for the year ended March 31, 1997. Gross profit increased
to $2.0 million for the twelve-month period ended March 31, 1998 from $1.7
million for the year ended March 31, 1997, an increase of $260,000, or 15.0%. As
a percentage of revenue, gross profit increased to 18.7% for the twelve-month
period ended March 31, 1998 from 17.9% for the twelve-month period ended March
31, 1997. Gross profit increased primarily due to higher revenue with a less
than proportional increase in contract costs.
 
   
     General and Administrative Expenses.  General and administrative expenses
were $1.2 million for the nine months ended December 31, 1997 and $1.5 million
for the year ended March 31, 1997. General and administrative expenses increased
to $1.6 million for the twelve-month period ended March 31, 1998 from $1.5
million for the year ended March 31, 1997, an increase of $82,000, or 5.5%. This
increase in general and administrative expenses was due to higher salaries and
wages. As a percentage of revenue, general and administrative expenses decreased
to 14.8% for the twelve-month period ended March 31, 1998 from 15.4% for the
twelve-month period ended March 31, 1997.

$157,000 for the twelve-month period ended March 31, 1998 from $78,000 for the
year ended March 31, 1997. As a percentage of revenue, net income increased to
1.5% for the twelve-month period ended March 31, 1998 from 0.8% for the year
ended March 31, 1997. The increase was the result of the increase in gross
profit discussed above.
 
  Year Ended March 31, 1997 Compared to Year Ended March 31, 1996
 
     Revenue.  Revenue increased to $9.7 million for the year ended March 31,
1997 from $6.7 million for the year ended March 31, 1996, an increase of $3.1
million, or 45.9%. This increase was the result of expanding into new markets
and the commencement of operations by Alpha-Keystone, which added revenue from
engineering services and facilitated the award of additional construction
contracts.
 
     Gross Profit.  Gross profit increased to $1.7 million for the year ended
March 31, 1997 from $1.5 million for the year ended March 31, 1996, an increase
of $204,000, or 13.3%. Despite the increase in gross profit, gross profit as a
percentage of revenue decreased to 17.9% for the year ended March 31, 1997 from
23.0% for the year ended March 31, 1996 due to lower profit margins on certain
contracts.
 
   
     General and Administrative Expenses.  General and administrative expenses
increased to $1.5 million for the year ended March 31, 1997 from $1.3 million
for the year ended March 31, 1996, an increase of $151,000, or 11.2%. As a
percentage of revenue, general and administrative expenses decreased to 15.4%
for the year ended March 31, 1997 from 20.2% for the year ended March 31,
    
                                       37
<PAGE>   41
 
1996. The decline in general and administrative expenses as a percentage of
revenue was a result of leveraging general and administrative expenses over a
higher sales volume despite an increase in salaries and wages.
 
     Net Income.  Net income decreased to $78,000 for the year ended March 31,
1997 from $123,000 for the year ended March 31, 1996, a decrease of $45,000, or
36.6%. As a percentage of revenue, net income decreased to 0.8% for the year
ended March 31, 1997 from 1.8% for the year ended March 31, 1996. The decrease
was the result of the lower margins on certain contracts discussed above.

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996
 
     Revenue.  Revenue decreased to $9.7 million for the year ended December 31,
1997 from $10.8 million for the year ended December 31, 1996, a decrease of $1.2
million, or 10.8%. This decrease was due to fewer contracts awarded through
competitive bidding.
 
     Gross Profit.  Gross profit decreased to $1.0 million for the year ended
December 31, 1997 from $1.5 million for the year ended December 31, 1996, a
decrease of $464,000, or 30.9%. As a percentage of revenue, gross profit
decreased to 10.7% for the year ended December 31, 1997 from 13.9% for the year
ended December 31, 1996. The decrease in gross profit was due to higher material
costs as a percentage of revenue.
 
     General and Administrative Expenses.  General and administrative expenses
remained constant at approximately $645,000 for the year ended December 31, 1997
and 1996. As a percentage of revenue, general and administrative expenses
increased to 6.7% for the year ended December 31, 1997 from 6.0% for the year
ended December 31, 1996. Although general and administrative expenses remained
stable, they increased as a percentage of revenue because a significant portion
of these expenses were fixed and did not decrease with revenue.
 
     Net Income.  Net income decreased to $433,000 for the year ended December
31, 1997 from $893,000 for the year ended December 31, 1996, a decrease of
$460,000, or 51.5%. As a percentage of revenue, net income decreased to 4.5% for
the year ended December 31, 1997 from 8.2% for the year ended December 31, 1996.
The decrease was the result of the decrease in revenues discussed above.
 
  Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
     Revenue.  Revenue increased to $10.8 million for the year ended December
31, 1996 from $9.3 million for the year ended December 31, 1995, an increase of
$1.5 million, or 16.4%. This increase was the result of incremental maintenance
projects in process during 1996.
 
     Gross Profit.  Gross profit increased to $1.5 million for the year ended
December 31, 1996 from $1.4 million for the year ended December 31, 1995, an
increase of $137,000, or 10.0%. As a percentage of revenue, gross profit
decreased to 13.9% for the year ended December 31, 1996 from 14.7% for the year
ended December 31, 1995 as a result of an increase in revenue from lower margin
contracts.
 
     General and Administrative Expenses.  General and administrative expenses
remained relatively constant for the years ended December 31, 1996 and 1995. As
a percentage of revenue, general and administrative expenses decreased to 6.0%
for the year ended December 31, 1996 from 6.9% for the year ended December 31,
1995 as result of leveraging general and administrative expenses over a higher
sales volume.
 
     Net Income.  Net income increased to $893,000 for the year ended December
31, 1996 from $804,000 for the year ended December 31, 1995, an increase of
$89,000, or 11.1%. As a percentage of revenue, net income decreased to 8.2% for
the year ended December 31, 1996 from 8.6% for the year ended December 31, 1995.

RAILROAD SERVICE, INC. AND AFFILIATE
 
     Founded in 1972, Railroad Service, Inc. ("Railroad Service") provides
construction, maintenance and rehabilitation services primarily to industrial
companies located in the Northern and Midwestern United States. Minnesota
Railroad Service, Inc. ("Minnesota Railroad"), an affiliate of Railroad Service,
provides the same services as Railroad Service but utilizes unionized laborers.
For 1997, Railroad Service and Minnesota Railroad estimate that, collectively,
they derived approximately 64% of revenue from new construction, approximately
32% from maintenance and repair and
 
                                       39
<PAGE>   43
 
approximately 4% from other services. Collectively, Railroad Service's and
Minnesota Railroad's revenue for 1997 was $9.4 million, representing 3.7% of the
Company's pro forma as adjusted revenue for 1997.
 
     The following table sets forth certain selected combined financial data and
data as a percentage of revenue for the periods indicated.

  Three Months Ended March 31, 1998 Compared to Three Months Ended March 31,
1997
 
     Revenue.  Revenue increased to $1.3 million for the three months ended
March 31, 1998 from $238,000 for the three months ended March 31, 1997, an
increase of $1.0 million. This increase was the result of the commencement of a
large contract pursuant to which most materials were installed initially, as
well as unseasonably good weather which increased the available working days
during the period.
 
   
     Gross Loss.  Gross loss decreased by $195,000 to $22,000 for the three
months ended March 31, 1998 from a gross loss of $217,000 for the three months
ended March 31, 1997. Contract costs exceeded revenue for the three-month
periods ended March 31, 1997 and 1998. The improvement in gross loss was due to
the increased absorption of fixed costs as revenue increased.
    
 
     General and Administrative Expenses.  General and administrative expenses
increased to $721,000 for the three months ended March 31, 1998 from $268,000
for the three months ended March 31, 1997, an increase of $453,000 due to a
transfer of stock between the owners of Railroad Service in 1998, which resulted
in a $400,000 charge to executive compensation. As a percentage of revenue,
general and administrative expenses decreased to 56.9% for the three months
ended March 31, 1998 from 112.6% for the three months ended March 31, 1997. The
decline in general and administrative expenses as a percentage of revenue was a
result of higher sales volume.
 
   
     Net Loss.  Net loss increased to $750,000 for the three months ended March
31, 1998 from $332,000 for the three months ended March 31, 1997, an increase of
$418,000, or 125.9%. As a percentage of revenue, net loss improved to 59.1% for
the three months ended March 31, 1998 compared to 139.5% for the three months
ended March 31, 1997. The increase in net loss and decrease in loss as a
percentage of revenue was the result of items discussed above.
    
 
  Year Ended December 31, 1997 Compared to Year Ended December 31, 1996
 
     Revenue.  Revenue decreased to $9.4 million for the year ended December 31,
1997 from $10.7 million for the year ended December 31, 1996, a decrease of $1.3
million, or 12.6%, due to the sale of a division of Railroad Service and, as a
result, fewer construction projects in process during the period.
 
     Gross Profit.  Gross profit decreased to $2.3 million for the year ended
December 31, 1997 from $2.5 million for the year ended December 31, 1996, a
decrease of $212,000, or 8.4%. As a percentage of revenue, gross profit
increased to 24.5% for the year ended December 31, 1997 from 23.4% for the year
ended December 31, 1996. The decrease in gross profit was a result of lower
revenue, offset in part by the higher profitability of remaining contracts.

     General and Administrative Expenses.  General and administrative expenses
increased to $1.5 million for the year ended December 31, 1997 from $1.4 million
for the year ended December 31, 1996, an increase of $32,000, or 2.3%. As a
percentage of revenue, general and administrative expenses increased to 15.5%
for the year ended December 31, 1997 from 13.2% for the year ended December 31,
1996. The slight increase in general and administrative expenses as a percentage
of revenue was a result of the fixed nature of a significant portion of general
and administrative expenses.
 
     Net Income.  Net income remained relatively stable at $977,000 for the year
ended December 31, 1997 compared to $1.0 million for the year ended December 31,
1996. Net income as a percentage of revenue increased to 10.4% from 9.4%. The
increase as a percentage of revenue was the result of the higher profitability
on contracts discussed above.
 
  Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
     Revenue.  Revenue increased to $10.7 million for the year ended December
31, 1996 from $9.0 million for the year ended December 31, 1995, an increase of
$1.7 million, or 18.4%, due to several incremental contracts in process.
 
     Gross Profit.  Gross profit increased to $2.5 million for the year ended
December 31, 1996 from $1.7 million for the year ended December 31, 1995, an
increase of $796,000, or 46.4%. As a percentage of revenue, gross profit
increased to 23.4% for the year ended December 31, 1996 from 19.0% for the year
ended December 31, 1995. The increase in gross profit as a percentage of revenue
was due to improved contract performance and a more favorable competitive
environment.
 
     General and Administrative Expenses.  General and administrative expenses
increased to $1.4 million for the year ended December 31, 1996 from $1.3 million
for the year ended December 31, 1995, an increase of $129,000, or 10.0%. As a
percentage of revenue, general and administrative expenses decreased to 13.2%
for the year ended December 31, 1996 from 14.3% for the year ended December 31,
1995. This decrease was a result of leveraging general and administrative
expenses over a higher sales volume, despite an increase in administrative
expense and wages.
 
     Net Income.  Net income increased to $1.0 million for the year ended
December 31, 1996 from $357,000 for the year ended December 31, 1995, an
increase of $649,000, or 181.8%. As a percentage of revenue, net income
increased to 9.4% for the year ended December 31, 1996 from 3.9% for the year
ended December 31, 1995. The increase was a result of the improved contract
performance discussed above
 
INFLATION
 
     The Company does not believe that inflation has had a material effect on
its results of operations in recent years. However, there can be no assurance
that the Company's business will not be affected by inflation in the future.
 
YEAR 2000
 
     The Company intends to replace all of the Founding Companies' computer
systems with a new integrated management information system during 1999. The new
system will be Year 2000 compatible. The Company believes that the effects, if
any, that Year 2000 issues may have on its business will not be material to the
Company's business, financial condition or results of operations.

OVERVIEW
 
   
     RailWorks Corporation was formed in March 1998 to become a leading
nationwide provider of rail system services, including construction and
rehabilitation, repair and maintenance, and related products. Management
selected the Founding Companies, which will be acquired by RailWorks Corporation
concurrently with the closing of the Offering, based on their regional or local
market leadership, diverse and long-standing customer relationships,
profitability and geographic diversity. The Combination will establish a
significant operating enterprise which management believes will serve as the
foundation for a consolidation of the highly-fragmented rail system services and
products industry. Based on their experience in the rail system services and
products industry, management believes that there is a trend among rail system
operators toward increased outsourcing of services and the use of fewer vendors,
although management is not aware of any independent corroborating data that
objectively confirms their belief. Management believes that the Combination and
future acquisitions will enable it to capitalize on this trend. The Company's
strategy is based on providing a full range of rail-related services and
products on a national basis and offering integrated rail system solutions under
the "RailWorks" brand. In 1997, on a pro forma as adjusted basis, the Company
had revenue of $256.5 million, operating income of $11.2 million and net income
of $5.4 million. For the three months ended March 31, 1998, on a pro forma as
adjusted basis, the Company had revenue of $61.8 million, operating income of
$1.5 million and net income of $655,000. Based on estimates of the Founding
Companies, management estimates that approximately 68.4% of the Company's pro
forma as adjusted revenue for the year ended December 31, 1997 was derived from
rail-related operations and 31.6% was derived from non-rail related operations.
    
 
INDUSTRY OVERVIEW
 
     The rail passenger and freight industries have undergone significant
changes in recent years. Changes in the industry have affected transit systems,
passenger railroads, regional and shortline railroads and Class I railroads. In
addition, industrial and other commercial companies that own and maintain their
own rail systems have become more focused on transportation logistics and
achieving cost efficiencies. These changes have resulted in an ongoing
reconfiguration of the country's rail infrastructure, significant new
construction projects and emerging demand for outsourced construction,
rehabilitation, repair and maintenance services.
 
     Companies install trackwork in their plants to transport raw materials,
equipment and finished goods. This trackwork consists of connector lines that
provide access to Class I or shortline railroads and railyards to coordinate the
shipment and delivery of cargo to and from their plants. Companies are
responsible for maintaining their own track and typically construct and
reconfigure trackage as part of plant construction and expansion. In addition,
many large companies that have previously relied on a single railroad for the
delivery of large quantities of raw materials or for the shipment of their
finished products have constructed rail lines to connect to alternate railroads.
Industrial companies build these "customer-owned" lines to improve the service
that they receive and to lower freight expenses, and typically use independent
contractors to design, construct and maintain these rail lines.
 
     The growth of major metropolitan areas and the aging of existing rail
systems have resulted in significant developments in passenger rail transit
services over the last 20 years. Heavy rail, commuter rail (service between
metropolitan and suburban areas) and light rail (typically, short trains
operating on rights-of-way that are not separated from other traffic) have
emerged as attractive alternatives to bus or automobile transit and older
commuter rail systems have been rehabilitated and extended to handle increased
ridership. Many older urban systems (such as the New York City subway system)
are undergoing significant rehabilitation and/or modernization, while major
heavy rail systems built in the 1970s (such as the systems in San Francisco and
Atlanta) are being extended and upgraded. Additionally, there have been several
recent initiatives to develop high-speed rail
                                       42
<PAGE>   46
 
transit networks between major urban areas (for example, in Florida and the
Northeast corridor). According to APTA, there are now 16 commuter rail agencies
in 13 urban areas and 22 light rail agencies nationwide. According to APTA,
commuter and light rail ridership has increased 28% and 56%, respectively, from
1985 to 1995. Since 1979, approximately 15 cities have constructed new light
rail-based transit systems and other cities have either extended or refurbished
their existing systems, with ridership increasing by approximately 150% over the
period from 1978 through 1996. On June 9, 1998, the President signed the
Transportation Equity Act for the 21st Century ("TEA 21"), which provides $42
billion of funds for transit projects during the next six fiscal years. See
"Government Regulation -- TEA 21." This represents more than a 40% increase of
funding from the previous six-year period. Accordingly, opportunities to provide
rail-related signaling, communication, electrical and track system construction,
rehabilitation, repair and maintenance services for transit systems have
increased and are expected to continue to increase significantly.
 
     As a result of industry consolidation there are only eight Class I
railroads (as defined by the STB) operating primarily in the United States
today, compared to 27 in 1980. These railroads are Burlington Northern Sante Fe
Railway, CSX Transportation, Kansas City Southern Lines, Norfolk Southern
Railway Company, Union Pacific, Consolidated Rail Corporation, Canadian National
and Canadian Pacific. According to the AAR, these railroads accounted for 73% of
the rail mileage operated in the United States and 91% of railroad revenue in
1996. In recent years, the Class I railroads have sought to rationalize their
systems, for example by "double-tracking" certain high traffic main lines and
abandoning portions of their systems that generate lower volumes of traffic.
Mergers of Class I systems have also created significant construction projects
as the systems are reconfigured and integrated. Historically, the major
railroads have been vertical organizations that sought to perform their own
construction and maintenance by utilizing specialized workforces and equipment
for these functions. Management believes that as Class I railroads seek to
continue to improve their cost structures, they will increasingly outsource
certain construction and maintenance functions to independent contractors.
 
     In recent years, the number and coverage of shortline and regional
railroads (i.e., those railroads which are not Class I railroads) have increased
significantly. The Staggers Rail Act of 1980 provided for partial deregulation
of the railroad industry and created mechanisms by which larger railroads could
more easily dispose of portions of rail line. Since that time, the larger
railroad systems in the United States have streamlined their operations by
disposing of portions of their systems that generate lower volumes of traffic
and other companies have acquired portfolios of shortline railroads. According
to the AAR, there are approximately 550 shortline and regional railroads, which
in the aggregate generated approximately 9% of all railroad revenue in 1997. The
percentage of total track miles operated by shortline and regional railroads in
the United States increased to 27% in 1995 from approximately 17% in 1986.
Shortline and regional railroads spend a relatively large portion of their
capital and operating budgets on maintenance of their track assets, because
these assets are often in poor condition when they are acquired. These railroads
typically utilize independent contractors for their maintenance and construction
programs, since they do not have systems large enough to support the purchases
of equipment and development of workforces that would be required for these
functions.
 
     Based on information published by the AAR and APTA, the Company estimates
that in 1997, expenditures by rail-based transit systems, railroads and
industrial companies on domestic rail system construction and maintenance
services of the types offered by the Founding Companies were approximately $14
billion, consisting of approximately $6 billion by passenger rail authorities
and transit authorities (including Amtrak), approximately $6 billion by Class I
railroads, approximately $1 billion by regional and shortline railroads and
approximately $1 billion by industrial companies. Additionally, the Company
believes that expenditures for these services outside the United States have
increased significantly in recent years as a result of infrastucture
construction and modernization programs, as well as privatization of large rail
systems. In many instances, foreign governments
 
                                       43
<PAGE>   47
 
and companies have sought the expertise of American designers, engineers and
construction managers.
 
     The Company believes that larger customers are seeking to establish
relationships with contractors that specialize in rail system services and
products and that can provide efficient, integrated solutions over the entire
life cycle of their assets. While there are numerous smaller rail system
construction, rehabilitation, repair and maintenance companies working in local
or regional markets, they are unable to compete with the larger companies
because their limited financial resources make it difficult for them to bid on
larger jobs and because they are unable to utilize their equipment and
workforces beyond their local and regional markets. Additionally, management
believes that larger rail systems and industrial companies are increasingly
seeking to enter into arrangements with a smaller number of contractors that can
provide services on a national or regional basis, in order to ensure centralized
management of their rail assets, adherence to uniform quality standards and more
cost-effective procurement practices.
 
COMPETITIVE STRENGTHS
 
     Breadth of Services and Products.  Management believes that rail system
operators are increasingly seeking to purchase services and supplies on an
integrated basis from fewer vendors. Management further believes that the
Company will offer a broader range of services and products than most industry
participants. The Company's service and product offerings include (i)
construction and rehabilitation of track, signaling, communications, electrical
and other track-related systems, (ii) repair and maintenance of these systems,
(iii) a broad range of rail-related products, including rail, ties, spikes,
frogs (rail intersections), tie plates and ballast and (iv) for its non-rail
customers, electrical installation services and concrete products. Based on
estimates of the Founding Companies, management estimates that revenue from
rail-related (i) construction and rehabilitation, (ii) repair and maintenance
and (iii) OTM and products accounted for 46.5%, 15.4% and 6.5%, respectively, of
the Company's pro forma as adjusted revenue for the year ended December 31, 1997
and non-rail services and products accounted for 31.6% of this revenue.
 
     Diverse Customer Base.  The Founding Companies' have long-standing
relationships with a wide variety of customers, including: (i) commercial and
industrial companies such as Commonwealth Edison, United States Steel and
Terminal One at JFK International (Airport), which have contracted with the
Company for track construction and maintenance or non-rail electrical
contracting work; (ii) transit authorities such as the New York Metropolitan
Transit Authority, the Los Angeles Metropolitan Transit Authority and the
Baltimore Metropolitan Transit Authority, which have contracted with the Company
for electrical installations, signaling, communications or station projects;
(iii) shortline railroads such as Indiana Southern Railroad Company, Branford
Steam Railroad and I&M Rail Link, which have contracted with the Company for
track construction and maintenance work or product supply; and (iv) Class I
railroads such as Illinois Central Railroad, Union Pacific Railroad and CSX
Transportation, which have utilized the Company for repair and maintenance,
construction or engineering.
 
     Expansive Geographic Coverage.  The Company has offices in 17 states and
has provided services and products to customers throughout the United States.
The Company's 33 facilities provide it with a geographically diverse mix of
established operating bases which enable it to undertake projects in a more cost
effective manner than would be possible absent a local facility. The Company
also has the ability to mobilize equipment and technical specialists throughout
the United States to maximize asset utilization and to complete projects in
remote locations.
 
STRATEGY
 
     The Company's goal is to become the leading provider of integrated rail
system solutions, offering a full range of rail-related services and products to
a diverse base of customers throughout the United States. In addition, the
Company expects to continue to provide non-rail services and products in
response to market opportunities. Key elements of the Company's strategy include
the following:
 
     Provide Integrated Solutions for Rail Systems.  Management believes that
rail system owners are increasingly seeking to outsource their construction,
rehabilitation, repair and maintenance requirements and to utilize fewer vendors
to provide a full range of these services and related products. As a result of
the Combination, the Company will be able to provide its customers with
 
                                       44
<PAGE>   48
 
integrated rail system solutions which management believes can be efficiently
designed, constructed, maintained, operated and supplied, resulting in lower
costs over the life cycle of customers' rail assets.
 
     Capitalize on Scale and Geographic Coverage.  The Company believes that the
increased scale that will be achieved through the Combination will position it
to undertake larger rail-related projects that are beyond the scope of those
previously undertaken by the individual Founding Companies. Each of the Founding
Companies was constrained by applicable bonding limits and the limited size of
its workforce. The Company also intends to utilize its geographic scope to
develop a national accounts program to serve rail customers with multiple sites
and "cross-sell" its broad range of rail-related services and products. The
Company currently has very limited international operations but over time the
Company may increase its activity in international markets, where privatizations
of railroads and large transit projects are creating increased demand for
sophisticated design and construction management services.
 
     Reduce Operating Costs.  The Company believes that the scale of its
operations and administrative integration of the Founding Companies following
the Combination will provide it with a better cost structure than its regional
and smaller competitors. Key areas in which the Company expects to achieve cost
savings include (i) purchasing of equipment and supplies, (ii) insurance
expenses, (iii) financing costs and (iv) utilization of equipment and the
Company's workforce. The Company also expects to reduce administrative expenses
through the integration of certain accounting, financing, human resources and
other functions.
 
     Expand Through Acquisitions.  The rail system services and products
industry is highly fragmented, and the Company believes that it is
well-positioned to pursue the consolidation of these segments on a nationwide
basis. Following the Offering, the Company expects to pursue an acquisition
program that will include (i) strategic acquisitions intended to expand the
Company's geographic coverage throughout the United States and broaden its lines
of services and products, (ii) acquisitions intended to position the Company to
offer its customers complementary services and products and (iii) smaller
"tuck-in" acquisitions intended to add density and operating leverage within the
Company's current markets. The Company believes that the experience and industry
reputations of the senior managers of the Founding Companies and senior
corporate management of the Company will provide it with a competitive advantage
in identifying, completing and integrating these acquisitions. The Company does
not intend to expand its non-rail business through acquisitions. The key
elements of the Company's acquisition strategy include the following:
 
          Enter New Geographic Markets.  The Company intends to expand into
     geographic markets it does not currently serve by acquiring
     well-established contractors and related supply companies that, similar to
     the Founding Companies, are leaders in their regional or local markets. In
     addition, the Company believes that after an initial emphasis on
     acquisitions within the United States, it may pursue international
     acquisition opportunities for further expansion.
 
          Enter Complementary Services and Product Markets.  The Company intends
     to acquire companies offering complementary services and products to those
     currently offered by the Founding Companies. Specifically, the Company
     believes that there will be attractive acquisition opportunities with
     respect to design and engineering firms, designers and manufacturers of
     signaling and communication systems and suppliers of electrical equipment,
     rail, switches and panels and concrete and steel ties.
 
          Expand Within Existing Geographic Markets.  The Company also plans to
     acquire additional companies in many of the regions in which it currently
     operates in order to expand the volume and scope of its operations in a
     particular market. The Company will pursue "tuck-in" acquisitions of
     smaller companies to increase utilization of its existing fixed assets and
     equipment or to gain access to new customers, thereby improving operating
     efficiencies and more effectively using its capital resources without a
     proportionate increase in administrative costs.
 
     Leverage Management Expertise.  The senior managers of each of the Founding
Companies have an average of 14 years of experience in the rail system services
and products industry. The Company will utilize a management structure which
will enable these individuals to focus on operations rather than administrative
tasks. In addition, the Company's Chief Executive Officer, Chief Financial
Officer and Chief Operating Officer each have in excess of 15 years of
experience in
 
                                       45
<PAGE>   49
 
the transportation industry, including, in the case of John Larkin (the
Company's Chief Executive Officer) approximately 11 years of experience as an
equity research analyst focusing on the transportation industry. Senior
management of the Company will coordinate the operations of the Founding
Companies, provide strategic guidance for the Company, implement the Company's
acquisition program and promote the development of national accounts. As part of
this strategy, the Company intends to foster a culture of cooperation and
teamwork among the Founding Companies that emphasizes dissemination of best
practices among its regional and local management teams and joint bidding on
larger projects. For example, management believes it can successfully implement
best practices in the areas of 24-hour emergency rerailment services, annual
maintenance contracts and efficient inventory management.
 
     The Company's non-rail related business consists primarily of commercial
and industrial electrical contracting provided by Comstock and the manufacture
and sale of concrete products by CPI Concrete. The Company intends to continue
to focus Comstock's business to benefit from its core competencies, including
rail-based transit projects, and to utilize Comstock's market position in its
non-rail business to exploit opportunities as they arise, but not to expand such
business significantly. The Company intends to expand both CPI Concrete's rail
and non-rail businesses by leveraging its customer base and geographic coverage.
The Company expects that its non-rail business, as a percentage of revenue, will
decrease over time.
 
SERVICES AND PRODUCTS
 
     The following is a summary of the primary services and products offered by
the Company.
 
     Rail-Related New Construction and Rehabilitation.  New construction
projects undertaken by the Company consist primarily of the installation of
traction, power, signalling and communication systems for rail-based transit
authorities and the construction of trackwork for commercial and industrial
companies and, to a lesser extent, transit authorities. Trackwork projects may
involve adding turnouts (i.e., connections between main lines and sidings),
expanding rail infrastructure or rebuilding outdated systems. In connection with
new track construction, the Company will assist with permits governing railroad
approvals, other regulatory requirements and subcontractor direction. Based on
estimates of the Founding Companies, management estimates that the Company
derived 46.5% of its pro forma as adjusted revenue for the year ended December
31, 1997 from new rail construction and rehabilitation.
 
     Rail-Related Repair and Maintenance.  The Company's repair services include
moving turnouts, adding rail car storage, and replacing ties, rail and/or
surfacing. The Company assists its customers with the design and implementation
of preventive maintenance programs that lengthen the life and provide for the
safer operation of the track components of their rail systems. Such maintenance
projects include tightening bolts, checking gauges, checking the track for
deviations in gauge, line and surface, surfacing the track, and lining the
track. The Company intends to focus on establishing regular maintenance programs
for its customers and believes that the industry is moving toward more
sophisticated maintenance programs. The Company also provides site services to
its customers, including excavation of the railbed, cutting, filling and
preparing the railbed, grading and subgrading, drainage and paving. Based on
estimates of the Founding Companies, management estimates that the Company
derived 15.4% of its pro forma as adjusted revenue for the year ended December
31, 1997 from rail-related repair and maintenance services.
 
     Rail-Related Products.  The Company believes its ability to offer materials
and supplies in conjunction with its construction, rehabilitation and
maintenance services will provide it with a competitive advantage in bidding on
rail system projects. Additionally, the Company's network of contractors
throughout the country will strive to provide leads for the Company's sales of
materials and supply. The Company seeks to provide its customers with a broad
range of products and materials required for the construction, rehabilitation
and maintenance of rail systems. Based on estimates of the Founding Companies,
management estimates that the Company derived 6.5% of its pro forma as adjusted
revenue for the year ended December 31, 1997 from the sale of products. Major
categories of products supplied by the Company include the following:
 
     - Rail.  The Company provides "relay" rail (previously used rail that
       remains suitable for use in yard, branch and secondary tracks). The
       Company offers products in a broad range of weights, including all major
       types of heavy and light rail.
 
                                       46

       including spikes, tie plates, joint bars, anchors, gage drives and bolts.
       Most of the products are offered in both new and "relay" forms.
 
     Non-Rail System Services and Products.  Through Comstock, the Company
provides a complete range of electrical and instrumentation installation
services, with a special emphasis on commercial buildings, heavy industrial and
manufacturing plants and power plants. Through CPI Concrete, the Company
provides a range of pre-stressed and pre-cast concrete products used in airport,
highway and bridge construction. Based on estimates of the Founding Companies,
management estimates that the Company derived 31.6% of its pro forma as adjusted
revenue for the year ended December 31, 1997 from these services and products.
 
     - Commercial.  Comstock provides electrical power and lighting installation
       services for commercial buildings primarily in the New York City
       metropolitan area. In recent years, Comstock has worked with commercial
       builders and developers on installations in office buildings, financial
       institutions, airport facilities, broadcast studios and retail complexes.
       Financial institution installations have included data/communications
       systems for brokerage firms, insurance companies and banks, with a
       specialization in large trading floors. Comstock provides electrical
       services for new construction, as well as on-site maintenance service for
       existing buildings.
 
     - Industrial and Manufacturing.  Comstock provides electrical and
       instrumentation installation services for heavy industrial and
       manufacturing plants throughout the United States. Services include both
       new construction and maintenance/modification, with recent projects
       including pulp and paper facilities, steel mills, chemical and
       petrochemical plants, oil refineries and automotive assembly plants.
 
     - Power.  Comstock provides electrical installation services for power
       plant construction and renovation projects throughout the United States.
       In addition to new plant construction, services provided by Comstock
       include life extensions, control upgrades, substations/switch yards and
       emissions control projects. Facilities services include coal-fired,
       hydroelectric, waste-to-energy and cogeneration plants.
 
     - Concrete Products.  CPI Concrete provides pre-stressed and pre-cast
       concrete products for highways and bridges, locks and dams, airports,
       power and light companies and buildings. Specifically, CPI Concrete
       offers its customers an assortment of decorative and utility poles and
       bridge girders along with wall panels, floors and roofs, columns, beams
       and other structural support elements.

THE FOUNDING COMPANIES
 
     The Founding Companies were selected based on their regional or local
market leadership, diverse and long-standing customer relationships,
profitability and geographic diversity. Furthermore, except for Comstock (which
accounts for 59.9% of the Company's pro forma as adjusted revenue for the year
ended December 31, 1997), no Founding Company accounts for more than 10.0% of
the Company's pro forma as adjusted revenue for that year. See "Risk
Factors -- History of Losses; Fluctuations in Quarterly Operating Results."
Following the Combination, the Company will offer a variety of services and
products throughout the United States to a variety of customer types. The
following charts represent the estimated breakdown of service/product revenue
mix, geographic region and customer type as a percentage of the Company's pro
forma as adjusted revenue for the year ended December 31, 1997:

(1) The information contained in these charts was compiled by the Company on the
    basis of an estimate by each Founding Company of the breakdown of its
    revenue for the 12 months ended December 31, 1997 by service/product,
    geographic region and customer type. During 1997, each Founding Company was
    independently owned and operated and, as a result, the methods for
    determining the revenue breakdown by service/product may not be uniform. For
    example, a Founding Company may have historically classified one type of
    project as rail-related maintenance and repair and another Founding Company
    may have historically classified the same type of project as rail-related
    rehabilitation. The Company aggregated these estimates to present the
    information contained above and elsewhere in this Prospectus.

ONGOING ACQUISITION PROGRAM
 
     The Company believes that it will be regarded by acquisition candidates as
an attractive acquiror based on: (i) the Company's strategy for creating a
professionally managed, integrated rail system construction, rehabilitation and
maintenance company that will operate throughout the United States and in
selected international markets; (ii) the Company's decentralized operating
strategy, which emphasizes an ongoing role for owners, management and key
personnel of acquired businesses, as well as meaningful equity positions for
these individuals, enabling them to participate in the Company's growth; (iii)
the Company's increased visibility and access to financial resources as a public
company; and (iv) the potential for increased profitability of the acquired
company due to savings in workforce and equipment utilization, improvements in
the purchasing and financing of equipment, centralization of administrative
functions and improved information systems capabilities.
 
     The Company believes that management of the Founding Companies will be
instrumental in identifying future acquisitions. Several of the principals of
the Founding Companies have leadership roles in industry trade associations,
which have enabled these individuals to become personally acquainted with the
owners of numerous acquisition targets across the country. See
"Management -- Executive Officers, Directors and Key Employees." The Company
expects that the visibility of these individuals and the Company within the rail
system industry will increase the awareness and interest of acquisition
candidates in the Company and its acquisition program. In addition, the Company
intends to utilize an internal acquisition team that will devote substantial
time to pursuing the Company's acquisition strategy. The Company currently has
no agreements, arrangements or understandings to effect any acquisitions other
than the Combination. There can be no assurance that the Company will identify,
acquire or manage profitably additional businesses or that financing will be
available for future acquisitions. See "Risk Factors -- Risks Associated with
Acquisition Strategy and Financing."
 
     The Company's acquisition program is expected to (i) expand its geographic
coverage throughout the United States, (ii) add density and operating leverage
within its current markets through smaller "tuck-in" acquisitions and (iii)
position the Company to offer its customers complementary services and products.
The Company intends initially to focus on acquisition opportunities within the
United States. However, the Company believes that after its initial domestic
emphasis it may look to international acquisition opportunities for further
expansion.
 
     As consideration for future acquisitions, the Company intends to use
various combinations of its Common Stock, cash and notes. The consideration for
each future acquisition will vary on a case-by-case basis, with the major
factors in establishing the purchase price being historical operating results,
future prospects of the target and the ability of the target to complement the
services and products offered by the Company. Within 90 days following the
completion of this Offering, the Company intends to register additional shares
of Common Stock under the Securities Act for its use in connection with future
acquisitions. The Company believes that it can structure acquisitions as
tax-free reorganizations by using its Common Stock as consideration.
 
SOURCES OF SUPPLY
 
     The Company purchases new rail from a limited number of suppliers. New rail
is generally installed only on main lines, where the track may carry high
volumes of heavy traffic at high speeds. Over time, rail is removed, inspected
and, if in appropriate condition, refurbished for sale as "relay" rail. Relay
rail is typically installed on secondary (non-main line) tracks, as well as yard
or branch tracks. Total rail life before scrapping may be as long as 60 years.
The Company also purchases a large volume of relay rail that is refurbished by
third parties and resold.
 
     Similarly, the Company regularly purchases entire sections of track that
are removed and subsequently disassembled at the Company's facilities. The
Company inspects the various track components -- rail, ties, and
accessories -- and items are placed into the Company's inventory
                                       50
<PAGE>   54
 
(either in their "as removed" condition or after being refurbished by third
parties) or sold by the Company for scrap. Additionally, in connection with
certain repair and rehabilitation projects, the Company acquires trackwork that
is removed.
 
     The Company believes that upon completion of the Combination, it will be
able to purchase materials in sufficient quantities to permit it to realize
purchasing economies and discounts from its suppliers. Additionally, the
Company's network of contractors is expected to position the Company to acquire
previously-used track on comparatively advantageous terms.
 
     In its installation of electrical signaling and communication systems for
transit authorities, the Company purchases equipment from a limited number of
suppliers. See "Risk Factors -- Reliance on Subcontractors and Suppliers."
 
     Two of the Founding Companies process creosote-treated wooden ties. Their
operations include the purchase of raw lumber, trimming the lumber to specified
sizes, pressurized impregnation of the lumber with creosote preservative and
finishing of the ties (which would include the pre-drilling of spike holes and
the attachment of plates, as specified by the customer). The service life of
pressure treated ties has been extended to a range of 25 to 40 years.
 
SALES AND MARKETING
 
     Upon completion of the Combination, the Company intends to implement a
targeted national sales program to further develop the business of each of the
Founding Companies. The focus of this initiative will be on the Class I
railroads and other large industrial companies with facilities in multiple
areas, which the individual Founding Companies have previously been unable to
serve on a comprehensive, nationwide basis. In addition, the Company's ability
to offer electrical installation services together with rail-related
construction, rehabilitation, repair and maintenance services and related
products is expected to result in opportunities for the Company to cross-sell
its services to large industrial companies. The Company believes that it will
have an advantage over its competitors since it will be able to offer
consistent, high-quality service and products in most regions of the United
States, thereby enabling customers to use the Company's services and products in
multiple locations rather than dealing with numerous regional or local
companies.
 
     The Combination will significantly broaden the respective offerings of
services and products of the Founding Companies, and management believes that
the Company will be positioned to achieve significant synergies in its marketing
programs. Management also believes that it will be able to develop cross-selling
programs under which (i) its design and engineering groups will provide timely
leads to its construction, product supply and electrical installation
subsidiaries, (ii) its electrical signaling and communications groups, which
have previously utilized third parties for track engineering and construction,
will be able to utilize the other Founding Companies for these projects, and
(iii) its track construction subsidiaries will be able to contract with Comstock
for signaling, communication and electrical installation services. Similarly,
the Company's product supply subsidiaries have, over the years, developed
long-term relationships with the Class I railroads and large industrial
companies, and the Company believes that these relationships will provide a
basis for marketing its construction and maintenance services.
 
     A majority of the Company's pro forma as adjusted revenue for the year
ended December 31, 1997 was derived from contracts entered into through a
competitive bidding process. Many projects that are competitively bid require
the company that is awarded the project to post a bond, which varies according
to the size of the project. Each company has a bonding limit, which is based on
the company's working capital and work in progress. The bond provides the
customer with insurance in the event that the company is unable to complete the
project. Accordingly, the ability of each of the Founding Companies to bid on
larger projects has been limited by its ability to obtain the required bonding.
The increased size of the Company following the Combination compared to the size
of each individual Founding Company will increase the bonding limits for each
Founding Company. Therefore, upon completion of the Combination and the
Offering, the Company believes that each
                                       51
<PAGE>   55
 
of the Founding Companies, as a subsidiary of the Company, will be positioned to
bid on and undertake significantly larger construction and maintenance projects.
Similarly, the Company also expects that the increased bonding capacity will
permit it to bid on and undertake more projects than could smaller companies.
 
CUSTOMERS
 
     Based on estimates of the Founding Companies, management estimates that the
Company derived 61.6% of its pro forma as adjusted revenue for the year ended
December 31, 1997 from industrial companies, commercial enterprises and
governmental entities (excluding transit authorities), 30.9% from rail-based
transit authorities, 6.0% from shortline and commuter railroads, and 1.5% from
Class I railroads. No single customer accounted for more than 6.0% of the
Company's pro forma as adjusted revenue for the year ended December 31, 1997.
The following table lists the top four customers of the Company in each category
on a pro forma as adjusted basis:

</TABLE>
                             
     Many of the customers that purchase products and supplies from the Founding
Companies, such as Class I railroads, have not historically used external
providers for their rail system construction, rehabilitation and maintenance
services. Following the Combination, the Company expects to leverage its
relationships with these customers into an additional source of customers for
its service businesses.
 
     A majority of the Company's business is generated through competitive
bidding, and the Company's track construction and repair suppliers generally do
not enter into long-term contracts with its customers. To a limited extent, the
Founding Companies have historically been suppliers to and customers of each
other. The Company expects that these relationships will continue following the
Combination, and that the Company's strategy of fostering cooperation and
teamwork will yield new opportunities for the Founding Companies and
subsequently acquired companies.
 
COMPETITION
 
     The rail system services and products industry is highly competitive, and
projects are often awarded through competitive bidding. The Company competes
with other rail system construction, rehabilitation and maintenance companies,
electrical contractors and suppliers of products, some of which have
significantly greater resources than the Company. An inability of the Company to
compete successfully against its existing and future competitors would have a
material adverse effect on its business, results of operations and financial
condition. Management believes the Founding Companies compete effectively in
their industries. Further, the Company believes that each Founding Company that
competes in the non-rail industry, competes effectively within its industry.
There are no substantial barriers to entry and additional competitors with
greater resources than the Company may enter the industry and compete
effectively against the Company. Certain competitors may also provide a broad
range of services and products and may have sufficient bonding capacity to
undertake large projects. Moreover, the Company may depend in part upon
opportunities for
 
                                       52
<PAGE>   56
 
consolidation in the rail system industry in order to execute effectively its
acquisition and vertical integration strategy. If the Company's customers do not
receive the Company's vertical integration strategy favorably, such customers
have numerous alternative sources of services and supply.
 
RISK MANAGEMENT AND SAFETY
 
     Because the Founding Company's businesses are labor intensive, workers'
compensation will be a significant operating expense for the Company. In
addition, the Company could be exposed to possible claims by its customers
alleging discrimination or harassment by the Company's employees. The Company
could also be exposed to liability for the acts or negligence of its employees
who cause personal injury or damage while on assignment, as well as claims of
misuse of client proprietary information or theft of client property. The
Company has adopted policies and procedures intended to reduce its exposure to
these risks.
 
     The Founding Companies maintain insurance against these risks with policy
limits they consider sufficient which they believe are consistent with industry
standards. The Company intends to retain a risk management professional who,
with the assistance of the Founding Company presidents, would be responsible for
claims management and the establishment of appropriate reserves for the
deductible portion of claims. The Company also expects to implement quarterly
safety committee meetings with the Founding Company presidents and conduct
routine safety inspections of local work sites.
 
EQUIPMENT AND FACILITIES
 
     The Founding Companies operate specialized equipment used in rail
construction, rehabilitation, repair and maintenance. This equipment is portable
and, consequently, the Company intends to share equipment where it is
appropriate and cost effective. For example, during the winter months, the
Founding Companies located in the Northern United States could relocate their
equipment to the Founding Companies located in the south. Each of the Founding
Companies generally performs its own equipment maintenance.
 
     The Company's corporate offices are in approximately 3,000 square feet of
leased space in a suburb of Baltimore, Maryland. In addition to its corporate
offices, upon consummation of the Combination, the Company will maintain the
following facilities:

GOVERNMENT REGULATION
 
     Overview.  In addition to the environmental, safety and other regulations
generally applicable to all businesses, the Company's business is impacted by
regulations that are administered by the STB, the successor to the Interstate
Commerce Commission ("ICC"), and the FRA and by regulatory agencies in the
various states in which the Company and its customers do business. Since 1980,
there has been a significant relaxation in regulations governing the sale,
leasing or other transfer of railroad properties, and this change has favorably
affected the operations of many of the Company's customers. Various interests in
the United States have sought and continue to seek reimposition of government
controls on the railroad industry in areas deregulated in whole or in part since
1980, including stricter rate regulation and more onerous labor protection
conditions for rail line transfers.
 
     Railroad Regulations.  The ICC Termination Act, which was enacted on
December 29, 1995, eliminated the ICC as an independent agency and created the
STB, a new agency within the Department of Transportation which began
functioning on January 1, 1996. The ICC Termination Act changed the procedure
and timing for federal approval of rail projects, including abandonments, line
sales, mergers, rates and tariffs, simplifying and streamlining the abandonment
process. The FRA regulates railroad safety and equipment standards, including
track maintenance and train speed standards, special procedures for handling
hazardous shipments, locomotive and railcar inspection and repair requirements,
operating practices and crew qualifications. The Roadway Worker Protection
Rules, which were promulgated by the FRA, apply to rail contractors and
establish certain safety criteria that must be complied with on rail projects.
 
     TEA 21.  On June 9, 1998, the President signed TEA 21, the six-year surface
transportation program that represents a significant development in the federal
transit program. TEA 21, the largest infrastructure funding bill in U.S.
history, authorizes funding for transit in the amount of $42 billion over six
years. TEA 21 authorizes over 40 percent more than the 1991 Intermodal Surface
Transportation Efficiency Act, whose funding has expired.
 
     State Regulatory Agencies.  State regulatory agencies no longer have
authority to engage in economic regulation of railroads that are part of the
intrastate network. State and local governments generally retain jurisdiction
over local rail safety matters, such as the installation of grade crossings and
grade crossing warnings devices.

ENVIRONMENTAL MATTERS
 
     The principal environmental regulatory requirements applicable to the
Company's operations relate to the use of creosote to treat lumber, and the
generation, storage, transportation and off-site treatment or disposal of solid
and hazardous wastes. The Company intends to implement environmental compliance
programs designed to maintain compliance with applicable technical and
operations requirements. The Founding Companies believe that their operations
have all required environmental permits and currently are in compliance, in all
material respects, with such regulatory requirements, except where the failure
to comply, either individually or in the aggregate, would not have a material
adverse effect on the Company's business, results of operations or financial
condition.
 
     The historical and current uses of the Company's facilities may have
resulted in spills or releases of various solid or hazardous wastes that may
contain hazardous substances ("Hazardous Substances"), which now, or in the
future, could require remediation. The Company also may be subject to
requirements related to remediation of Hazardous Substances that have been
released into the environment at properties that it owns or operates, or owned
or operated in the past or at properties to which it sends, or may have sent,
Hazardous Substances for treatment or disposal. Such remediation requirements
generally are imposed without regard to fault, and liability for any required
environmental remediation can be substantial. There are currently no claims,
either threatened or pending, against the Company for environmental remediation
of Hazardous Substances which individually or in the aggregate would have a
material adverse effect on the Company's business, results of operations or
financial condition.
 
EMPLOYEES
 
     On a pro forma combined basis as of March 31, 1998, the Company employed
approximately 1,748 employees, all of whom were full-time employees.
Approximately 1,533 of the Company's employees were engaged in operations, and
215 were engaged in a variety of sales, administrative and managerial functions.
The Company believes that its relations with all of its employees are good.
 
     An aggregate of approximately 1,175 people employed by Annex, Comstock,
Kennedy, Merit, Midwest, New England and U.S. Trackworks are members of certain
labor unions and are employed pursuant to a collective bargaining agreement.
Certain of the Founding Companies are parties to collective bargaining
agreements with the International Brotherhood of Electrical Workers, Laborers'
International Union of North America, the International Union of Operating
Engineers, United Brotherhood of Carpenters and Joiners of America and the
United Brotherhood of Teamsters. Certain of the Founding Companies' customers
only hire unionized labor. Furthermore, except for a one-week work stoppage in
Connecticut by the United Brotherhood of Teamsters in June 1994, the Founding
Companies have experienced no work stoppages in the past five years.
 
INFORMATION TECHNOLOGY SYSTEMS
 
     The Company will require integrated information technology systems in order
to effectively integrate, manage and optimize its operations, particularly as it
executes its growth strategy. The Company is in the process of selecting and
implementing the required systems and plans to complete the process following
the Combination. The Company believes that these information technology systems
will be used for a variety of purposes, including monitoring inventory levels,
tracking the progress of construction projects and integrating of the Company's
financial, general ledger, payables and receivables function. In addition, the
Company will network its corporate offices to the offices of the Founding
Companies and will have e-mail capability to all offices. The Company expects
that the required systems will be purchased and installed in 1999 and that its
expenditures for these systems will not be material to the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Pro Forma As Adjusted Liquidity and Capital Resources." All of the
new systems will be Year 2000 compatible. Until these new systems are fully
operational, each of the Founding Companies will continue using the information
systems that are currently being utilized.

LEGAL PROCEEDINGS
 
     From time to time, the Company may be involved in routine legal proceedings
incidental to the conduct of its business. In the opinion of management, the
litigation, individually or in the aggregate, to which the Company is currently
a party, is not likely to have a material adverse effect on the Company's
business, financial condition and results of operations.
 
ORGANIZER
 
   
     The Company was organized by IPODC, which was not previously affiliated
with any of the Founding Companies. IPODC identified the Founding Companies,
arranged for the Company's retention of its executive officers and managed the
initial organizational stages of the Combination and the Offering. In exchange
for the services provided by IPODC, the Founding Companies have agreed to pay
IPODC or its designees upon the completion of the Combination and the Offering,
a fee equal to 3 1/2% of the total consideration paid to the Founding Companies
in the Combination excluding the cash portion of the consideration paid to
Comstock. Such fee will be paid out of the cash and shares of Common Stock to be
received by the Founding Companies.

EMPLOYMENT AGREEMENTS
 
     The Company has conducted limited operations and generated no revenue to
date and did not pay any of its executive officers compensation during 1997. The
Company anticipates that during 1998 its most highly compensated executive
officers will be Messrs. Larkin, Azarela, Kennedy and Kropp.
 
                                       60
<PAGE>   64
 
   
     The Company has entered into employment agreements with each of the Named
Executive Officers. The agreements expire on December 31, 2001 (the "Expiration
Date") and will continue on a year-to-year basis, unless terminated by either
party. Each agreement is terminable by the Company with or without cause or upon
the employee's death or inability to perform his duties on account of a
disability for a period of six months during any consecutive twelve month period
or by the employee. The agreements provide for annual base salaries of $275,000,
$200,000, $100,000 and $135,000 for Messrs. Larkin, Azarela, Kennedy and Kropp,
respectively, and provide that these executive officers will receive 5%, 2%,
1.5% and 1.5% respectively, of the Company's first bonus pool (the "First Bonus
Pool") and 33.3%, 13.3%, 10.0% and 10.1%, respectively, of the Company's second
bonus pool (the "Second Bonus Pool"). The First Bonus Pool will consist of 10%
of the Company's pre-tax profits and the Second Bonus Pool will consist of 15%
of the amount by which the Company's net income exceeds certain benchmarks. In
addition, the agreements provide that each Executive Officer of the Company will
be granted shares of restricted stock and options to purchase Common Stock, as
set forth herein. At any time after the Offering, the employee may request a
loan from the Company in the amount of the income taxes due on stock granted to
the employee under his employment agreement. The loan will be collateralized
only by the stock granted and the employee otherwise will not be personally
obligated to repay the loan. The term of the loan will be five years, requiring
annual interest payments; however, the term will be accelerated following
termination of employment. Each agreement will also contain noncompetition,
nonsolicitation and confidential information provisions.
    
 
     Upon consummation of the Combination, the Company will enter into
employment agreements with certain employee-stockholders of each Founding
Company. The agreements will expire on the second anniversary of the closing
date of the Offering. On and after such date, the employees may give twelve
months written notice of termination of the agreement (the "Expiration Date").
Each agreement will be terminable by the Company with or without cause or upon
the employee's death or inability to perform his duties on account of a
disability for a period of six months during any consecutive twelve-month period
or by the employee. Each agreement will provide for an annual base salary and
will provide that the salary will be adjusted after the initial term of the
agreement to reflect the employee's duties and responsibilities. Furthermore,
each employee will be entitled to a portion of the First Bonus Pool and the
Second Bonus Pool. As a group, the owners of the Founding Companies will be
entitled to an aggregate of 40% of the First Bonus Pool and 33.3% of the Second
Bonus Pool.
 
EXECUTIVE COUNCIL
 
     Upon consummation of the Combination, each Founding Company President will
be appointed to the Company's Executive Council, which will be chaired by John
Kennedy, the Company's Vice President and Chief Operating Officer. The Executive
Council will meet weekly to participate in short- and long-term planning
sessions, coordinate the Company's marketing efforts, discuss new jobs that are
out for bid and establish best practices. In addition, the Executive Council
will present its views regularly to the Board of Directors.
 
1998 STOCK INCENTIVE PLAN
 
     The Company's Board of Directors has adopted, and the Company's
stockholders have approved, the Company's Incentive Plan. There are 2,000,000
shares of Common Stock reserved for issuance under the Incentive Plan. The
purpose of the Incentive Plan is to provide executive officers, directors and
key employees with additional incentives by enabling such persons to increase
their ownership interests in the Company. Individual awards under the Incentive
Plan may take the form of one or more of: (i) either incentive stock options
("ISOs") or non-qualified stock options ("NQSOs," and together with ISOs,
"Options"); (ii) stock appreciation rights ("SARs"); (iii) restricted or
deferred stock; (iv) dividend equivalents; (v) bonus shares and awards in lieu

whole or in part upon the value of the Common Stock. Upon a change of control of
the Company (as defined in the Incentive Plan), certain conditions and
restrictions relating to an award with respect to the exercisability or
settlement of such award will lapse.
 
     The Compensation Committee will administer the Incentive Plan and generally
select the individuals who will receive awards. In addition, the Compensation
Committee will determine the type and number of awards and the terms and
conditions of those awards (including exercise prices, vesting and forfeiture
conditions, performance conditions and periods during which awards will remain
outstanding). The Incentive Plan also provides that no participant may be
granted in any calendar year awards which may be settled by delivery of more
than 100,000 shares and limits payments under cash-settled awards in any
calendar year to an amount equal to the fair market value of that number of
shares.
 
     The Company generally will be entitled to a tax deduction equal to the
amount of compensation realized by a participant through awards under the
Incentive Plan, except that (i) no deduction is permitted in connection with
ISOs if the participant holds the shares acquired upon exercise for the required
holding periods, and (ii) deductions for some awards could be limited under the
$1.0 million deductibility cap of Section 162(m) of the Internal Revenue Code of
1986, as amended (the "Code"). This limitation, however, should not apply to
awards granted under a plan during a grace period of up to three years following
the Offering, and should not apply to certain options, SARs and
performance-based awards granted thereafter if the Company complies with certain
requirements under Section 162(m) of the Code.
 
     The Incentive Plan will remain in effect until terminated by the Board of
Directors. The Incentive Plan may be amended by the Board of Directors without
the consent of the stockholders of the Company, except that any amendment,
although effective when made, will be subject to stockholder approval if
required by any federal or state law or regulation or by the rules of any stock
exchange or automated quotation system on which the Common Stock may then be
listed or quoted.

              CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
 
     Set forth below is a description of certain transactions and relationships
between RailWorks Corporation and certain persons who will become officers,
directors and principal stockholders of the Company following the Combination
and the Offering. In addition, set forth below is certain information regarding
transactions and relationships prior to the Combination between certain of the
Founding Companies and their respective officers, directors and principal
stockholders.
 
ORGANIZATION OF RAILWORKS CORPORATION
 
     RailWorks Corporation was formed in March 1998 as a holding company to
acquire businesses in the rail service and supply industry. Prior to the
Combination and the Offering, RailWorks Corporation issued 10 shares of Common
Stock for cash to Mr. Larkin, the Company's Chairman and Chief Executive
Officer. For information regarding certain employment arrangements between the
Company and certain directors, officers and key employees, see
"Management -- Employment Agreements."
 
THE COMBINATION
 
   
     Simultaneously with and as a condition to the closing of the Offering,
RailWorks Corporation will consummate the Combination pursuant to the
Acquisition Agreements pursuant to which it will acquire each Founding Company
in a reverse subsidiary merger. Assuming an initial public offering price of
$12.00 per share, the aggregate consideration to be paid by RailWorks
Corporation in the Combination will be approximately $158.3 million (subject to
adjustment), which consists of (i) $51.9 million in cash, which will be paid
from the proceeds of the Offering (representing 92.9% of the estimated net
proceeds of the Offering) and (ii) the $106.4 million estimated fair value of
8,867,648 shares of Common Stock to be issued to the stockholders of the
Founding Companies. For information regarding the consideration paid to each
Founding Company, see "Formation of the Company -- the Combination." In
addition, in connection with the Combination, the Company will assume $35.0
million of indebtedness of certain of the Founding Companies (including $1.6
million of indebtedness incurred to partially finance the redemption of shares
of Common Stock of a Founding Company held by an ESOP). Such indebtedness will
be repaid with a portion of the proceeds (representing 7.1% of the estimated net
proceeds of the Offering) of the Offering and with borrowings under the
Company's Credit Facility.
    
 
   
     As a result of the Combination, all 22 Founding Companies will become
wholly-owned subsidiaries of RailWorks Corporation. The consummation of each
Acquisition Agreement is contingent upon the consummation of the Offering and
customary closing conditions. The Acquisition Agreements require certain of the
executive officers of each of the Founding Companies to enter into employment
agreements with their respective Founding Companies effective upon consummation
of the Combination. In addition, one or more executives of certain of the
Founding Companies will be elected to the Board of Directors of the Company
following the consummation of the Offering. After the Offering, the stockholders
of the Founding Companies, management of the Company and IPODC will own in the
aggregate 63.5% of the outstanding Common Stock, assuming the over-allotment
option is not exercised. The recipients of shares of Common Stock in the
Combination are Selling Stockholders and, therefore, they may be deemed to be
"statutory underwriters" for purposes of the Securities Act. See "Formation of
the Company," "Management -- Employment Agreements," "Shares Eligible for Future
Sale," and the Unaudited Pro Forma As Adjusted Financial Statements and the
notes thereto appearing elsewhere in this Prospectus.

OTHER TRANSACTIONS
 
     Certain of the Founding Companies have engaged in transactions with
companies that are under common ownership, which transactions are described
below. Any future transactions between the Company and its officers, directors
or principal stockholders will be approved by a majority of the disinterested
members of the Board of Directors.
 
  Comstock
 
   
     RailWorks will acquire all of the outstanding stock of Comstock in a
reverse subsidiary merger for (i) $13.1 million in cash and (ii) 2,803,555
shares of Common Stock. In connection with the acquisition, Peter Alan Pasch,
the President and Chief Operating Officer of Comstock, will become a
    
 
                                       64
<PAGE>   68
 
director of the Company. Mr. Pasch will enter into a two-year employment
agreement with Comstock after the acquisition.
 
   
     Effective January 1, 1997, Comstock acquired all of the outstanding stock
of L. K. Comstock from Spie for $5.0 million plus a contingent payment of up to
$5.0 million based on 1997, 1998 and 1999 pre-tax income. In May 1998, Comstock
agreed to pay Spie $1.6 million in lieu of such contingent payment. Such
payment, which will be paid by the Company, is due on September 9, 1998, subject
to the completion of the Combination.
    
 
     In connection with the Comstock Acquisition, Comstock, L. K. Comstock, Spie
and CGI entered into an Indemnity and Cooperation Agreement pursuant to which
L.K. Comstock issued a contingent promissory note to Spie in the amount of
approximately $14.9 million (the "Contingent Note") collateralized by any
proceeds derived from three projects (the "Spie Projects") for which Comstock
had not been fully paid. Each of these projects is the subject of a lawsuit in
which L.K. Comstock is suing for payment of a portion of the contract price. In
each proceeding, the defendant has filed a counterclaim against L.K. Comstock
for breach of contract. Spie is obligated to indemnify L.K. Comstock for all
losses and expenses incurred with respect to these lawsuits. The Contingent Note
is payable only from amounts collected by L.K. Comstock with respect to the Spie
Projects prior to April 3, 2007, at which time the Contingent Note will be
canceled. As such, Spie and any successor or creditor may not look to any other
assets of L.K. Comstock or the Company to satisfy the Contingent Note. Because
there is a right of offset for any gains or losses incurred in connection with
the Spie Projects, neither the Contingent Note nor the right to receive proceeds
from the Spie Projects is reflected in Comstock's financial statements or the
Company's Unaudited Pro Forma As Adjusted Financial Statements.
 
  Kennedy
 
   
     RailWorks will acquire all of the outstanding stock of Kennedy,
Alpha-Keystone and Railcorp in reverse subsidiary mergers for an aggregate of
(i) $2.8 million in cash and (ii) 365,984 shares of Common Stock. Mr. Fulton
Kennedy, the President of Kennedy, is the brother of John Kennedy, the Vice
President and Chief Operating Officer and a director of the Company. Fulton
Kennedy will enter into a two-year employment agreement with Kennedy after the
Acquisition.
    
 
  Merit
 
   
     RailWorks will acquire all of the outstanding stock of Merit in a reverse
subsidiary merger for (i) $2.0 million in cash and (ii) 303,782 shares of Common
Stock. In connection with the acquisition, Mr. Steve C. Goggin, the President of
Merit, will become a director of the Company. Mr. Goggin will enter into a
two-year employment agreement with Merit after the Acquisition.
    
 
     Mr. Goggin is the sole shareholder of Shelter Rail Leasing. Annex leases
certain equipment from Shelter Rail Leasing and lease payments to Shelter Rail
Leasing totaled $181,500 in 1997. All payments to Shelter Rail Leasing will be
terminated upon consummation of the Combination.
 
  Railroad Service
 
   
     RailWorks will acquire all of the outstanding stock of Railroad Service and
Minnesota Railroad in reverse subsidiary mergers for an aggregate of (i) $3.5
million in cash and (ii) 509,017 shares of Common Stock. Mr. Scott D. Brace, the
President of Railroad Service, will become a director of the Company. Mr. Brace
will enter into a two-year employment agreement with Railroad Service after the
Acquisition.
    
 
     Mr. Brace is a 44% shareholder of Railroad Services and Minnesota Railroad.
Railroad Services and Minnesota Railroad periodically make payments for
subcontracting and administrative services to each other throughout the year.
 
  U.S. Trackworks
 
   
     RailWorks will acquire all of the outstanding stock of U.S. Trackworks and
Northern Rail in reverse subsidiary mergers for an aggregate of (i) $1.3 million
in cash and (ii) 304,450 shares of Common Stock. In connection with the
acquisition, Mr. Lambertus L. Tameling, the President of U.S. Trackworks, will
become a director of the Company. Mr. Tameling will enter into a two-year
employment agreement with U.S. Trackworks after the Acquisition.

                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 100,000,000 shares
of Common Stock, par value $0.01 per share, and 10,000,000 shares of preferred
stock, par value $0.01 per share. The following summary description of the
capital stock of the Company does not purport to be complete and is subject to
the detailed provisions of, and qualified in its entirety by reference to, the
Company's Certificate of Incorporation and Bylaws, copies of which have been
filed as exhibits to the registration statement of which this Prospectus forms a
part, and to the applicable provisions of the DGCL.
 
COMMON STOCK
 
     The holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. Subject to the
rights of any holders of Preferred Stock, holders of Common Stock are entitled
to receive ratably such dividends as may be declared by the Board of Directors
out of funds legally available. See "Dividend Policy." In the event of a
liquidation, dissolution or winding up of the Company, holders of the Common
Stock are entitled to share ratably in the distribution of all assets remaining
after payment of liabilities, subject to the rights of any holders of preferred
stock of the Company. The holders of Common Stock have no preemptive rights to
subscribe for additional shares of the Company and no right to convert their
Common Stock into any other securities. In addition, there are no redemption or
sinking fund provisions applicable to the Common Stock. All of the outstanding
shares of Common Stock are, and the shares of Common Stock offered hereby will
be, fully paid and nonassessable.
 
PREFERRED STOCK
 
     The Company has 10,000,000 shares of authorized but undesignated preferred
stock. The Board of Directors is authorized to provide for the issuance of
additional classes and series of preferred stock out of these undesignated
shares, and the Board of Directors may establish the voting powers,
designations, preferences and relative, participating, optional or other special
rights and qualifications, limitations or restrictions of any such additional
class or series of preferred stock, including the dividend rights, dividend
rate, terms of redemption, redemption price or prices, conversion rights and
liquidation preferences of the shares constituting any series, without any
further vote or action by the stockholders of the Company. The issuance of
preferred stock by the Board of Directors could have the effect of making it
more difficult for a third party to acquire a majority of the outstanding voting
stock of the Company, thereby delaying, deferring or preventing a change in
control of the Company.
 
CERTAIN PROVISIONS OF DELAWARE LAW AND THE COMPANY'S CERTIFICATE OF
INCORPORATION AND BYLAWS
 
     The Company is subject to the provisions of Section 203 of the DGCL.
Section 203 prohibits a publicly-held Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed manner.
A "business combination" includes a merger, asset sale or other transaction
resulting in a financial benefit to the interested stockholder. Subject to
certain exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns or within three years prior to the proposed
business combination has owned 15% or more of the corporation's voting stock.
 
     The Company's Certificate of Incorporation provides that liability of
directors of the Company is eliminated to the fullest extent permitted under
Section 102(b)(7) of the DGCL. As a result, no director of the Company will be
liable to the Company or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for liability: (i) for any breach of the
director's duty of loyalty to the Company or its stockholders; (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law; (iii) for any willful or negligent
 
                                       67
<PAGE>   71
 
payment of an unlawful dividend, stock purchase or redemption; or (iv) for any
transaction from which the director derived an improper personal benefit.
 
     The Company's Bylaws provides that the Board of Directors be elected to
staggered one-, two-and three-year terms and, thereafter, for successive
three-year terms. In addition, directors may only be removed from office for
cause. These provisions of the Bylaws could discourage potential acquisition
proposals and could delay or prevent a change in control of the Company.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock is First Union
Shareholder Services.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of the Offering, the Company will have 15,073,530 shares of
Common Stock outstanding, assuming consummation of the Combination. The
5,000,000 shares sold in the Offering will be freely tradeable without
restriction or further registration under the Securities Act, unless acquired by
an "affiliate" of the Company, as that term is defined in Rule 144. Shares held
by affiliates will be subject to resale limitations of Rule 144 described below.
All of the remaining 10,073,530 outstanding shares of Common Stock will be
available for resale at various dates beginning 180 days after the date of this
Prospectus, upon expiration of applicable lock-up agreements described below and
subject to compliance with Rule 144 as the holding provisions of Rule 144 are
satisfied. In addition, 2,000,000 shares of Common Stock are reserved for
issuance pursuant to the Company's Incentive Plan. Upon consummation of the
Offering, options to purchase 20,000 shares of Common Stock will be granted
pursuant to the Incentive Plan to non-employee directors of the Company. Such
options will vest and become exercisable 25% per year commencing on the date of
grant. The Company intends to file a registration statement on Form S-8 as soon
as practicable after the consummation of the Offering with respect to the
restricted shares and the shares of Common Stock issuable upon exercise of all
such options. In addition, within (i) 90 days following the completion of the
Offering, the Company intends to register shares of Common Stock under the
Securities Act for its use in connection with future acquisitions and (ii) 180
days after the Offering the Company intends to file a shelf registration
statement to register up to 1.4 million shares of Common Stock to permit sales
of such shares of Common Stock by the Selling Stockholders and IPODC.
    
 
     In general, under Rule 144 as currently in effect, a stockholder who has
beneficially owned for at least one year shares privately acquired directly or
indirectly from the Company or from an affiliate of the Company, and persons who
are affiliates of the Company who have acquired the shares in registered
transactions, will be entitled to sell within any three-month period a number of
shares that does not exceed the greater of: (i) one percent of the outstanding
shares of Common Stock (approximately 150,735 shares immediately after
completion of the Offering); or (ii) the average weekly trading volume in the
Common Stock during the four calendar weeks preceding such sale. Sales under
Rule 144 are also subject to certain requirements relating to the manner and
notice of sale and the availability of current public information about the
Company.
 
     The Company has agreed with the Underwriters that it will not offer, sell
or issue any shares of Common Stock or options, rights or warrants to acquire
any Common Stock for a period of 180 days after the date of this Prospectus
without the prior written consent of BT Alex. Brown Incorporated, except for
grants of options under the Incentive Plan and shares issued (i) in connection
with acquisitions and (ii) pursuant to the exercise of options granted under the
Incentive Plan. In addition, the Company's directors and executive officers and
the Selling Stockholders have agreed with the Underwriters not to directly or
indirectly offer for sale, sell or otherwise dispose of any Common Stock for a
period of 180 days after the date of this Prospectus without the prior written
consent of BT Alex. Brown Incorporated, except for sales of Common Stock by the
Selling Stockholders upon the exercise of the Underwriters' over-allotment
option, if any. Further, the stockholders of each of the Founding Companies have
agreed with the Company that they will not
 
                                       68
<PAGE>   72
 
sell, pledge, transfer or otherwise dispose of any shares of Common Stock for a
period of one year from the date of the closing of the Combination.
 
     From the first anniversary of the consummation of the Offering to the
fourth anniversary of the consummation of the Offering the Company will make
available selling opportunities for the recipients of Common Stock in the
Combination to sell at various dates a certain number of shares of Common Stock
owned by them. Every quarter during the foregoing period, these owners of Common
Stock will be permitted to sell up to 8% of the Common Stock received by them.
If such owner does not sell such shares in a given quarter, such owner may sell
such shares in any later quarter, provided that in no event may an owner sell
more than 20% of the shares of Common Stock received by such owner in any one
quarter. The Company may elect to make available (i) additional opportunities to
sell shares of Common Stock and/or (ii) the opportunity to sell an amount in
excess of such amount in any particular quarter. Such sales will take place
either through block trades or registered offerings.
 
     Prior to this Offering, there has been no market for the Common Stock. No
predictions can be made with respect to the effect, if any, that public sales of
shares of the Common Stock or the availability of shares for sale will have on
the market price of the Common Stock after the completion of the Offering. Sales
of substantial amounts of Common Stock in the public market following the
Offering, or the perception that such sales may occur, could adversely affect
the market price of the Common Stock or the ability of the Company to raise
capital through sales of its equity securities. See "Risk Factors -- No Prior
Market for the Common Stock; Possible Volatility of Stock Price."

     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will purchase all of the shares of Common Stock offered hereby if
any such shares are purchased.
 
     The Company and the Selling Stockholders have been advised by the
Representatives that the Underwriters propose to offer the shares of Common
Stock to the public at the initial public offering price set forth on the cover
page of this Prospectus and to certain dealers at such prices less a concession
not in excess of $          per share. The Underwriters may allow, and such
dealers may reallow, a concession not in excess of $          per share to
certain other dealers. After commencement of the initial public offering, the
offering price and certain other terms may be changed by the Representatives.
 
   
     The Selling Stockholders have granted to the Underwriters an option,
exercisable not later than 30 days from the date of this Prospectus, to purchase
up to 750,000 additional shares of Common Stock at the initial public offering
price less the underwriting discounts and commissions set forth on the cover
page of this Prospectus. To the extent that the Underwriters exercise such
option, each of the Underwriters will have a firm commitment to purchase
approximately the same percentage thereof that the number of shares of Common
Stock to be purchased by it in the above table bears to 5,000,000 and the
Selling Stockholders will be obligated, pursuant to the option, to sell such
shares to the Underwriters. The Underwriters may exercise such option only to
cover over-allotments made in connection with the sale of the Common Stock
offered hereby. If purchased, the Underwriters will offer such additional shares
on the same terms as those on which the 5,000,000 shares are being offered.
    
 
     The Common Stock has been approved for quotation on The Nasdaq National
Market under the symbol "RWKS."
 
   
     At the request of the Company, the Underwriters have reserved up to 250,000
shares of Common Stock offered hereby for sale at the initial public offering
price to certain employees of the Company and to certain other persons. The
number of shares available for sale to the general public will be reduced to the
extent that such persons purchase such reserved shares. Any reserved shares not
so purchased will be offered by the Underwriters to the general public on the
same basis as the other shares of Common Stock offered hereby.

     The Underwriting Agreement contains covenants of indemnity and contribution
between the Underwriters, the Company and the Selling Stockholders regarding
certain liabilities, including liabilities under the Securities Act.
 
     To facilitate the Offering of the Common Stock, the Underwriters may engage
in transactions that stabilize, maintain or otherwise affect the market price of
the Common Stock. Specifically, the Underwriters may over-allot shares of the
Common Stock in connection with this Offering, thereby creating a short position
in the Underwriters' syndicate account. Additionally, to cover such over-
allotments or to stabilize the market price of the Common Stock, the
Underwriters may bid for, and purchase, shares of the Common Stock in the open
market. Any of these activities may maintain the market price of the Common
Stock at a level above that which might otherwise prevail in the open market.
The Underwriters are not required to engage in these activities, and, if
commenced, any such activities may be discontinued at any time. The
Representatives, on behalf of the Underwriters, also may reclaim selling
concessions allowed to an Underwriter or dealer, if the syndicate repurchases
shares distributed by that Underwriter or dealer.
 
     The Company has agreed that it will not offer, sell or issue any shares of
Common Stock or options, rights or warrants to acquire any Common Stock for a
period of 180 days after the date of this Prospectus without the prior written
consent of BT Alex. Brown Incorporated, except for grants of options under the
Incentive Plan and shares issued (i) in connection with acquisitions and (ii)
pursuant to the exercise of options granted under the Incentive Plan. In
addition, the Company's directors and executive officers and the Selling
Stockholders have agreed not to directly or indirectly offer for sale, sell or
otherwise dispose of any Common Stock for a period of 180 days after the date of
this Prospectus without the prior written consent of BT Alex. Brown
Incorporated, except for sales of Common Stock by the Selling Stockholders upon
the exercise of the Underwriters' over-allotment option, if any.
 
     The Representatives have informed the Company that the Underwriters do not
intend to confirm sales to any account over which they exercise discretionary
authority.
 
     From time to time, each of the Underwriters and their respective affiliates
may provide investment banking services to the Company.
 
   
     Prior to this Offering, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock will be determined
by negotiations between the Company and the Representatives. Among the factors
to be considered in determining the initial public offering price will be
prevailing market conditions, the future prospects of the Company and its
industry in general, revenue, earnings and certain other financial and operating
information of the Founding Companies in recent periods, and the price-earnings
ratios, price-sales ratios, market prices of securities and certain financial
and operating information of companies engaged in activities similar to those of
the Company.

                    CERTAIN U.S. FEDERAL TAX CONSIDERATIONS
                      FOR NON-U.S. HOLDERS OF COMMON STOCK
 
     The following is a general discussion of certain U.S. federal income and
estate tax consequences of the ownership and disposition of Common Stock
applicable to a beneficial owner thereof that is a "Non-U.S. Holder." A
"Non-U.S. Holder" is a person or entity other than (i) a citizen or resident of
the United States, (ii) a corporation or partnership created or organized in or
under the laws of the United States or of any state, (iii) an estate the income
of which is subject to U.S. federal income tax, regardless of its source or (iv)
a trust if (a) a court within the United States is able to exercise primary
supervision over the administration of the trust and (b) one or more United
States persons have the authority to control all substantial decisions of the
trust.
 
     An individual may, subject to certain exceptions, be deemed to be a
resident alien (as opposed to a non-resident alien) by virtue of being present
in the United States at least 31 days in the calendar year and for an aggregate
of at least 183 days during a three-year period that includes the current
calendar year (counting for such purposes all of the days present in the current
year, one-third of the days present in the immediately preceding year, and
one-sixth of the days present in the second preceding year). Resident aliens are
subject to U.S. federal tax as if they were U.S. citizens and, thus, are not
Non-U.S. Holders for purposes of this discussion.
 
     This discussion is based on the Code existing and proposed regulations
promulgated thereunder and administrative and judicial interpretations thereof
as of the date hereof, all of which are subject to change, including changes
with retroactive effect. This discussion does not address all aspects of U.S.
federal income and estate taxation that may be important to Non-U.S. Holders in
light of their particular circumstances (including tax consequences applicable
to Non-U.S. Holders that are, or hold interests in Common Stock through,
partnerships or other fiscally transparent entities) and does not address United
States state and local or non-United States tax consequences. Prospective
Non-U.S. Holders should consult their own tax advisors with respect to the
particular U.S. federal income and estate tax consequences to them of owning and
disposing of Common Stock, as well as the tax consequences arising under the
laws of any other taxing jurisdiction.
 
DIVIDENDS
 
     Subject to the discussion below, dividends, if any, paid to a Non-U.S.
Holder of Common Stock generally will be subject to United States withholding
tax at a rate of 30% of the gross amount of the dividend or such lower rate as
may be specified by an applicable income tax treaty. Non-U.S. Holders (and in
the case of Non-U.S. Holders that are treated as partnerships or other fiscally
transparent entities, partners, shareholders or other beneficiaries of such
Non-U.S. Holders) may be required to satisfy certain certification requirements
and provide certain information in order to claim treaty benefits. Special rules
regarding the availability of treaty benefits apply with respect to entities
that are treated as partnerships or other fiscally transparent entities for U.S.
federal income tax purposes but treated as corporations for purposes of the tax
laws of an applicable treaty country (or, conversely, treated as corporations
for U.S. federal income tax purposes but treated as partnerships or other
fiscally transparent entities for purposes of the tax laws of an applicable
treaty country). Any such entities that hold Common Stock, and partners,
beneficiaries and shareholders of such entities, should consult their tax
advisors as to the applicability of such rules to their particular
circumstances.
 
     Dividends paid to a Non-U.S. Holder that are (i) effectively connected with
the Non-U.S. Holder's conduct of a trade or business within the United States
and (ii) if a tax treaty applies, attributable to a permanent establishment
maintained by the Non-U.S. Holder, will not be subject to the withholding tax
(provided in either case the Non-U.S. Holder files the appropriate documentation
with the Company or its Paying Agent), but, instead, will be subject to regular
U.S. federal income tax at the graduated rates in the same manner as if the
Non-U.S. Holder were a U.S. resident. In addition to such graduated tax in the
case of a Non-U.S. Holder that is a corporation, effectively
 
                                       72
<PAGE>   76
 
connected dividends or, if a tax treaty applies, dividends attributable to a
U.S. permanent establishment of the corporate Non-U.S. Holder, may be subject to
a "branch profits tax" which is imposed, under certain circumstances, at a rate
of 30% (or such lower rate as may be specified by an applicable tax treaty) of
the non-U.S. corporation's effectively connected earnings and profits, subject
to certain adjustments.
 
GAIN ON DISPOSITION OF COMMON STOCK
 
     A Non-U.S. Holder generally will not be subject to U.S. federal income tax
(and no tax will generally be withheld) with respect to gain realized on a sale
or other disposition of Common Stock unless (i) the gain is effectively
connected with a trade or business of such Non-U.S. Holder in the United States
or, if a tax treaty applies, attributable to a United States permanent
establishment of the Non-U.S. Holder, (ii) in the case of certain Non-U.S.
Holders who are nonresident alien individuals and hold the Common Stock as a
capital asset, such individuals are present in the United States for 183 or more
days in the taxable year of the sale or other disposition and certain other
conditions are met, (iii) the Non-U.S. Holder is subject to tax pursuant to the
provisions of the Code regarding the taxation of U.S. expatriates or (iv) the
Company is or has been a "U.S. real property holding corporation" within the
meaning of the Code and the Non-U.S. Holder owned directly or pursuant to
certain attribution rules more than 5% of the Company's Common Stock (assuming
the Common Stock is regularly traded on an established securities market within
the meaning of the Code) at any time within the shorter of the five-year period
preceding such disposition or such Non-U.S. Holder's holding period. The Company
is not, and does not anticipate becoming, a U.S. real property holding
corporation.
 
     If a Non-U.S. Holder who is an individual falls under clause (i) of the
preceding paragraph, he or she will, unless an applicable treaty provides
otherwise, be taxed on the net gain derived from the sale at regular graduated
U.S. federal income tax rates. If an individual Non-U.S. Holder falls under
clause (ii) of the preceding paragraph, he or she will be subject to a flat 30%
tax on the gain derived from the sale, which may be offset by certain United
States-source capital losses. If a Non-U.S. Holder that is a corporation falls
under clause (i) in the preceding paragraph, it will be taxed on the net gain
from the sale at regular graduated U.S. federal income tax rates and may be
subject to an additional branch profits tax at a rate of 30% (or such lower rate
as may be specified by an applicable tax treaty) on the non-U.S. corporation's
effectively connected earnings and profits, subject to certain adjustments.
 
INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING
 
     Generally, the Company must report annually to the Internal Revenue Service
(the "IRS") the amount of dividends paid to a Non-U.S. Holder and the amount, if
any, of tax withheld with respect to, such Non-U.S. Holder. A similar report is
sent to the Non-U.S. Holder. Pursuant to tax treaties or certain other
agreements, the Internal Revenue Service may make its reports available to tax
authorities in the recipient's country of residence.
 
     Currently, United States backup withholding tax (which generally is a
withholding tax imposed at a rate of 31% on certain payments to persons that
fail to furnish the information required under the United States information
reporting requirements) will generally not apply to dividends paid on Common
Stock to a Non-U.S. Holder at an address outside the United States, unless the
payor has actual knowledge that the payee is a U.S. Holder. Backup withholding
tax generally will apply to dividends paid on Common Stock at addresses inside
the United States to Non-U.S. Holders who fail to provide certain identifying
information in the manner required.
 
     In addition, information reporting and backup withholding imposed at a rate
of 31% will apply to the proceeds of a disposition of Common Stock paid to or
through a U.S. office of a broker unless the disposing holder, under penalties
of perjury, certifies as to its non-U.S. status or otherwise establishes an
exemption. Generally, U.S. information reporting and backup withholding will not
 
                                       73
<PAGE>   77
 
apply to a payment of disposition proceeds if the payment is made outside the
United States through a non-U.S. office of a non-U.S. broker. However, U.S.
information reporting requirements (but not backup withholding) will apply to a
payment of disposition proceeds outside the United States if the payment is made
through an office outside the United States of a broker that is (i) a U.S.
person, (ii) a foreign person which derives 50% or more of its gross income for
certain periods from the conduct of a trade or business in the United States or
(iii) a "controlled foreign corporation" for U.S. federal income tax purposes,
unless the broker maintains documentary evidence that the holder is a Non-U.S.
Holder and certain other conditions are met, or the holder otherwise establishes
an exemption.
 
     Recently adopted United States Treasury regulations, (the "New Withholding
Regulations") alter the foregoing rules in certain respects. The New Withholding
Regulations generally are effective for payments made after December 31, 1998,
subject to certain transition rules. The IRS recently issued a notice announcing
the intent of the Treasury Department and the IRS to amend the New Withholding
Regulations so that they generally will not apply to payments made before
January 1, 2000. Among other things, the New Withholding Regulations provide
certain presumptions under which a Non-U.S. Holder is subject to backup
withholding at the rate of 31% and information reporting unless the Company
receives certification from the holder of non-U.S. status. Depending on the
circumstances, this certification will need to be provided (i) directly by the
Non-U.S. Holder, (ii) in the case of a Non-U.S. Holder that is treated as a
partnership or other fiscally transparent entity, by the partners, shareholders
or other beneficiaries of such entity, or (iii) by certain qualified financial
institutions or other qualified entities on behalf of the Non-U.S. Holder.
 
     Backup withholding is not an additional tax. Rather, the tax liability of
persons subject to backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained, provided that the required information is furnished to the IRS.
 
FEDERAL ESTATE TAX
 
     An individual holder who is not a citizen or resident (as defined for U.S.
federal estate tax purposes) of the United States and at the time of death is
treated as the owner of, or has made certain lifetime transfers of, an interest
in the Common Stock will be required to include the value thereof in his gross
estate for U.S. federal estate tax purposes, and may be subject to U.S. federal
estate tax unless an applicable estate tax treaty provides otherwise.

                             RAILWORKS CORPORATION
 
              UNAUDITED PRO FORMA AS ADJUSTED FINANCIAL STATEMENTS
                             BASIS OF PRESENTATION
 
   
     The following unaudited pro forma as adjusted financial statements give
effect to the acquisitions by RailWorks Corporation (the "Company") of Annex
Railroad Builders, Inc. and Affiliates ("Annex"), Comstock Holdings, Inc.
("Comstock"), Comtrak Construction, Inc. ("Comtrak"), Condon Brothers,
Inc.("Condon"), CPI Concrete Products Incorporated ("CPI"), H.P. McGinley,
Incorporated ("McGinley"), Kennedy Railroad Builders, Inc. and Affiliates
("Kennedy"), Merit Railroad Contractors, Inc. ("Merit"), Midwest Construction
Services, Inc. ("Mid-West"), New England Railroad Construction Company, Inc.
("New England"), Railroad Service, Inc. and Affiliate ("Railroad Service"),
Southern Indiana Wood Preserving Company, Inc. ("Southern Indiana"), U.S.
Trackworks, Inc. and Affiliate ("Trackworks"), and Wm. A. Smith Construction
Co., Inc. and Affiliate ("Smith"), (together, the "Founding Companies"). These
acquisitions (the "Combination") will occur simultaneously with the closing of
the Company's initial public offering (the "Offering") and will be accounted for
using the purchase method of accounting. Pursuant to the requirements of SAB 97,
Comstock has been identified as the accounting acquiror for accounting and
financial statement purposes as its owners will receive the largest portion
(32.8%) of the shares of Common Stock issued to the Founding Companies in the
Combination.
    
 
     The unaudited pro forma as adjusted balance sheet gives effect to the
Combination and the Offering as if they had occurred on March 31, 1998. The
unaudited pro forma as adjusted statement of income for the year ending December
31, 1997, gives effect to these transactions as if they had occurred on January
1, 1997, while the unaudited pro forma as adjusted statement of income for the
three months ended March 31, 1998, gives effect to these transactions as if they
had occurred on January 1, 1998.
 
     The Company has identified certain savings which are expected to occur as a
result of the Combination. These savings have been reflected in the unaudited
pro forma as adjusted statements of income. The Company has analyzed certain
additional savings that it expects to realize by consolidating certain
operational and general and administrative functions. The Company has not and
cannot quantify these savings until completion of the Combination of the
Founding Companies. These anticipated additional savings have not been included
in the pro forma as adjusted financial information of the Company.
 
     The pro forma adjustments are based on preliminary estimates, available
information and certain assumptions and may be revised as additional information
becomes available. The pro forma as adjusted financial data does not purport to
represent what the Company's financial position or results of operations would
actually have been if such transactions in fact had occurred on those dates or
to project the Company's financial position or results of operations for any
future period. Since the Founding Companies were not under common control or
management, historical combined results may not be comparable to, or indicative
of, future performance. The unaudited pro forma as adjusted financial statements
should be read in conjunction with the other financial statements and notes
thereto included elsewhere in this Prospectus. See "Risk Factors" included
elsewhere herein.

     The purchase price will be allocated to the assets purchased and
liabilities assumed based on their estimated fair values. As Comstock has been
determined to be the accounting acquiror, the excess of the amount paid for
Comstock over its net book value, $46.2 million, is not included in the purchase
price allocation. The estimated fair values of the assets purchased and

     Management is currently evaluating the assets purchased and liabilities
assumed. Any change in the estimated fair values will result in a corresponding
change in goodwill. Additionally, any difference between the estimated price of
$12.00 per share of the Company common stock issued to the owners of the
Founding Companies in connection with the Combination and the actual price per
share will result in a corresponding change to goodwill.
    
 
4. PRO FORMA BALANCE SHEET AND STATEMENT OF INCOME ADJUSTMENTS
 
     a. Records the elimination of the historical stockholders' equity of the
Founding Companies (excluding Comstock).
 
     b. Adjusts the carrying value of property, plant and equipment purchased
from the Founding Companies (excluding Comstock) to estimated fair market value
and records the related deferred income taxes.
 
   
     c. Records an estimate of the goodwill and other intangible assets and the
related deferred income taxes to be recorded in connection with the Combination
as the result of the related issuance of shares and notes payable to the
stockholders of the Founding Companies and expenses associated with the
Combination. The total purchase price related to the shares issued is based upon
an estimated fair value of $12.00 per share which represents the estimated
initial public offering price.
    
 
     d. Records the pro forma goodwill amortization expense using a 40-year
estimated life and the pro forma other intangible assets amortization using a
10-year estimated life.
 
     e. Records the pro forma depreciation of the increased carrying value of
property, plant and equipment.
 
     f. Records contingent purchase price due to the former owner of a Founding
Company.
 
   
     g. Records the (1) planned purchase of a minority shareholder and (2)
planned distributions to owners of Founding Companies prior to the Combination.
The purchase price of the minority shareholder is estimated based on the value
assigned to the Founding Company in the Combination.
    
 
   
     h. Records the granting of 1,205,872 shares to management at an estimated
price of $12.00 per share. This amount will be charged to expense in the period
in which the grant occurs, but has not been reflected in the unaudited pro forma
as adjusted statements of income herein.

     i. Reduces compensation expense to the level that the owners of the
Founding Companies have contractually agreed to receive subsequent to the
Combination. In 1997, the owners of the Founding Companies received total
compensation of $6,914,000, consisting of salary of $3,826,000 and bonuses of
$3,088,000. Subsequent to the Combination, they will receive total estimated
compensation of $3,141,000. The change in compensation structure reflects the
conversion from the compensation arrangements normally paid to owners of
closely-held companies to those found in a publicly-held company and the change
in responsibilities of the individuals. Additionally, this adjustment reduces
compensation expense for personnel which have been terminated in conjunction
with Comstock's cost reduction initiatives.
    
 
     j. Records estimated expenses for the Company's new corporate office,
including compensation for the executive officers.
 
     k. Reflects the savings to be realized on a lease renewal by a Founding
Company.
 
     l. Reflects the reduction of insurance costs to be realized by the Company
as a group as opposed to the combined historical cost to the Founding Companies.
 
     m. To eliminate identifiable, incremental costs incurred by the Founding
Companies in conjunction with the Combination which are not expected to be
recurring.
 
     n. To eliminate the compensation expense recorded by a Founding Company in
connection with transfers of stock between existing stockholders.
 
     o. To eliminate a $295,000 nonrecurring fee earned by a Founding Company in
connection with services provided for its former owner.
 
     p. Records the incremental provision for federal and state income taxes
assuming a 39% statutory tax rate increased by goodwill amortization which is
not deductible for income tax purposes.
 
   
     q. Includes: (i) 8,867,648 shares issued to the stockholders of the
Founding Companies in connection with the Combination, (ii) 5,000,000 shares
issued by the Company in connection with this Offering, and (iii) 1,205,882
shares to be issued to management.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
     RailWorks Corporation ("RailWorks" or the "Company"), was formed in March
1998 to become a leading nationwide provider of rail services, including system
construction and rehabilitation, repair and maintenance services and related
products. RailWorks intends to acquire fourteen U.S. businesses (the
"Acquisitions"), complete an initial public offering (the "Offering") of its
common stock and, subsequent to the Offering, continue to acquire, through
merger or purchase, similar companies to expand its national operations.
 
     RailWorks has not conducted any operations, and all activities to date have
related to the Acquisitions and the Offering. Cash of $100 was generated from
the initial capitalization of the Company (see Note 2). Accordingly, cash flows
would not provide meaningful information and have been omitted. There is no
assurance that the pending acquisitions discussed below will be completed and
that RailWorks will be able to generate future operating revenues.
 
2. STOCKHOLDER'S EQUITY
 
     In connection with the organization and initial capitalization of
RailWorks, the Company issued 10 shares of common stock for $100.
 
3. SUBSEQUENT EVENTS (UNAUDITED)
 
     RailWorks and its newly formed, wholly owned subsidiaries have signed
definitive agreements to acquire by merger the Founding Companies to be
effective with the Offering. The companies to be acquired are: Annex Railroad
Builders, Inc. and Affiliates, Comtrack Construction, Inc., Comstock Holdings,

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Annex Railroad Builders, Inc. and Affiliates:
 
     We have audited the accompanying combined balance sheets of ANNEX RAILROAD
BUILDERS, INC. (an Indiana corporation) AND AFFILIATES (collectively, the
"Company") as of March 31, 1997 and December 31, 1997, and the related combined
statements of operations, stockholders' equity and cash flows for the year ended
March 31, 1997 and the nine months ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Annex Railroad Builders,
Inc. and Affiliates as of March 31, 1997 and December 31, 1997, and the results
of their operations and their cash flows for the year ended March 31, 1997 and
the nine months ended December 31, 1997 in conformity with generally accepted
accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS ACTIVITIES
 
     The accompanying combined financial statements of Annex Railroad Builders,
Inc. and Affiliates (collectively the "Company") include the accounts of Annex
Railroad Builders, Inc. ("Annex") (an Indiana corporation), R. & M. B. Rail Co.,
d/b/a Mize Construction Company ("Mize") (an Indiana corporation), Railroad
Specialties, Inc., ("RSI") (an Indiana corporation) and U.S. Railway Supply,
Inc. ("US Rail") (an Indiana corporation). These entities are included in the
combined financial statements due to certain shareholder's majority ownership in
each. The majority of the Company operates as a construction contractor
constructing, repairing, and maintaining railroad tracks for private and
government customers located throughout the Midwest. This work is performed
under various forms of contracts, including fixed-fee and time-and-material
contracts. One entity operates a supply company that provides railroad
construction supplies to certain railroad construction contractors.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF COMBINATION
 
     The above companies have been included in the combined financial
statements. All material intercompany transactions and balances have been
eliminated. Although the fiscal year of Annex ends March 31, the affiliates are
included in the combined financial statements on the basis of fiscal years
ending December 31. In 1997, Annex changed its financial reporting year-end to
December 31.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could vary from the estimates that were assumed
in preparing the financial statements.
 
REVENUE AND COST RECOGNITION
 
     The Company recognizes revenues from fixed-fee contracts using the
percentage-of-completion method, measured by the percentage of cost incurred to
date to management's estimated total cost for each contract. This method is used
because management considers total cost to be the best available measure of
progress on the contracts. Changes in job performance, job conditions and
estimated profitability may result in revisions to cost and income, which are
recognized in the period in which the revisions are determined.
 
     Revenues from time-and-material contracts are recognized currently as the
work is performed.
 
     Contract costs include all direct material, labor and equipment costs and
those indirect costs related to contract performance and are charged to expense
as incurred. Provisions for estimated losses on uncompleted contracts are made
in the period in which such losses are determined.
 
     The asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts," represents billings in excess of revenues recognized.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
CASH AND CASH EQUIVALENTS
 
     The Company considers cash and cash equivalents to include cash on hand and
temporary cash investments purchased with an original maturity of three months
or less.
 
FINANCIAL INSTRUMENTS AND CREDIT RISK
 
     The Company operates primarily in the Midwest. As such, the Company's
accounts receivable are from the same geographic region. The terms of the sales
give rise to unsecured accounts receivable, as is common industry practice.
Contract revenue earned from three customers comprised approximately 29% of
total contract revenue for the nine months ended December 31, 1997.
 
INVENTORY
 
     Inventory, consisting principally of stored materials and parts to be used
for contracts, is stated at the lower of cost or market. Cost is determined by
the first-in, first-out (FIFO) method.
 
PROPERTY, PLANT AND EQUIPMENT
 
     The Company records property, plant and equipment at cost. Depreciation is
computed using the straight-line and accelerated methods over the estimated
useful life of the asset as follows:
 
<TABLE>
<S>                                                       <C>
Buildings...............................................  27.5 - 39 years
Machinery and equipment.................................          5 years
Office furniture and equipment..........................          7 years
</TABLE>
 
     As assets are retired or otherwise disposed of, the cost and accumulated
depreciation are eliminated from the accounts, and any gain or loss is reflected
in net income.
 
INCOME TAXES
 
     Mize, RSI and U.S. Rail operate as Sub-Chapter S Corporations. Accordingly,
the taxable income of Mize, RSI, and US Rail included in the combined financial
statements of the Company is reported by the owners in their respective
individual tax returns; therefore, the combined financial statements of the
Company do not reflect an income tax provision for these entities.
 
     The provision for income taxes is based on earnings reported by Annex. In
accordance with Statement of Financial Accounting Standards No. 109, a deferred
income tax asset or liability is determined by applying currently enacted tax
laws and rates to the expected reversal of the cumulative temporary differences
between the carrying value of assets and liabilities for financial statement and
income tax purposes.
 
INTERIM FINANCIAL STATEMENTS
 
     The unaudited financial statements included herein have been prepared,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission ("SEC"). In the opinion of management, the accompanying
unaudited financial statements reflect all adjustments necessary to present
fairly the financial position as of March 31, 1998 and the results of operations
and cash flows for the three months ended March 31, 1997 and 1998.

11. COMMITMENTS AND CONTINGENCIES
 
LITIGATION
 
     The Company is engaged in various lawsuits arising in the ordinary course
of business. In the opinion of management, based upon the advice of counsel, the
ultimate outcome of these lawsuits will not have a material impact on the
Company's financial statements.
 
12. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following disclosure of estimated fair values of financial instruments
is made in accordance with the requirements of SFAS No. 107, "Disclosures about
Fair Value of Financial Instruments." The estimated fair value amounts have been
determined by the Company using available market information and appropriate
valuation methodologies.
 
CASH, ACCOUNTS RECEIVABLE AND ACCOUNTS PAYABLE
 
     The carrying amounts of these items are a reasonable estimate of their fair
value due to their short-term nature.
 
LINE OF CREDIT, LONG-TERM DEBT AND CAPITAL LEASE OBLIGATIONS
 
     The carrying amount of the line of credit facility approximates fair value
as the interest rate fluctuates with changes in market conditions. The carrying
amount of long-term debt and capital lease obligations based on borrowing rates
currently available to the Company is a reasonable estimation of fair value.
 
13. SUBSEQUENT EVENT (UNAUDITED)
 
     On May 21, 1998, the stockholders of the Company entered into an Agreement
and Plan of Reorganization (the "Agreement") with RailWorks Corporation. Under

related statements of income, shareholder's equity and cash flows for each of
the two years in the period ended December 31, 1996. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Comstock Holdings, Inc. and
subsidiary as of December 31, 1997, and the results of their operations and
their cash flows for the year ended December 31, 1997 and of the financial

                         NOTES TO FINANCIAL STATEMENTS
 
(1) BASIS OF FINANCIAL STATEMENT PRESENTATION
 
     Comstock Holdings, Inc. (formerly LKC Acquisition Corp.) (together with its
predecessor company, "Holdings" or the "Company"), was incorporated on November
20, 1996 as a Delaware corporation for the purpose of acquiring L.K. Comstock &
Company, Inc. (the "Predecessor Company"). Holdings had no operations from
incorporation through January 1, 1997.
 
     Effective January 1, 1997, the Company purchased the stock of the
Predecessor Company. The accompanying financial statements, including those of
the Predecessor Company prior to the acquisition date, have been prepared by
Holdings management and present the financial position and results of operations
of Holdings from the acquisition date and of the Predecessor Company for the
periods prior to the acquisition date. Accordingly, the financial information
for periods prior to the acquisition date does not reflect the significant
impact of the acquisition or of the purchase accounting adjustments on the
financial position and results of operations of Holdings.
 
     The Predecessor Company was acquired by Holdings through various agreements
(the "Agreements") entered into by Comstock Group, Inc. ("Group", the
Predecessor Company's former parent), Spie Group Inc. ("Spie", the parent of
Group), Spie Enertrans SA ("Enertrans", the former parent of Spie) and Schneider
Electric Holdings Inc. ("Schneider", the parent of Spie). The Agreements
principally called for: (1) the sale of the common stock of the Predecessor
Company to Holdings (the "Sale"), (2) the issuance of various contingent
promissory notes by the Company to Enertrans and Group in exchange for
approximately $18,903,000, (3) the transfer of various intangible assets of Spie
to the Company, (4) the provision for various income tax elections and
indemnifications, and (5) certain other indemnifications and cooperative
understandings, all as described below. Also in connection with Agreements, the
Company entered into certain borrowing arrangements with its lenders (see Note
6). The effects of the Agreements have been accounted for as a purchase in the
accompanying financial statements as of January 1, 1997.
 
     The principal terms of the Agreements are as follows:
 
          (1) The payment at closing of $5,105,000 to Group by Holdings. Such
     payment was substantially funded by the Predecessor Company.
 
          (2) Contingent payments by Holdings to Group of 30% of the Company's
     annual pre-tax income, as defined, through 1999 up to an aggregate of

     $2,500,000.
 
     Accordingly, a distribution of $294,000 has been accrued to fund the
estimated 1997 contingent purchase price payment with a corresponding reduction
of excess of acquired net assets over cost.
 
     Also under the terms of the Agreement, under certain conditions, Enertrans
has the right of first refusal for a period of three years for the subsequent
resale of the Predecessor Company's common shares by Holdings.
 
     As part of the Agreements, certain intangible assets (recorded at no value)
were assigned to the Company. In addition, the Company issued a promissory note
(the "Contingent Promissory Note"), collateralized by certain investments
related to customer contracts involving claims and an investment in a joint
venture (the "Investments"). The remaining balance of the Contingent Promissory
Note of $14,451,000 at December 31, 1997 is payable only from amounts collected
by the Company relating to the Investments until April 3, 2007, at which time
the note is cancelled. As such, Enertrans and any successor to it or creditor
may not look to any other Company assets to satisfy this

indebtedness. Accordingly, management believes a right of offset exists for
financial reporting purposes and the Investments and the Contingent Promissory
Note have been offset in the accompanying balance sheet at December 31, 1997 in
accordance with SFAS No. 125 "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities."
 
     In connection with the sale, $5,095,000 of cash from the Predecessor
Company was used by Holdings to fund its acquisition of the Predecessor Company.
Accordingly, and as a result of the purchase price adjustments, the fair value
of the net assets acquired exceeds the purchase price funded solely by Holdings.
In accordance with Accounting Principles Board Opinion 16 "Business
Combinations", the excess of the cost of net assets acquired first reduced the
non current assets to zero with the remainder allocated to "Excess of Acquired
Net Assets Over Cost", (negative goodwill) which amount will be amortized over
40 years.
 
     Group was acquired by Spie through a series of incremental investments
completed in 1989 and accounted for as a purchase. The principal accounting
effect on the Predecessor Company of this purchase was the push down of the
excess of the purchase price over net assets acquired (goodwill), which amount
was amortized over 40 years. In March 1995, the Financial Accounting Standards
Board issued, and the Predecessor Company adopted, Statement No. 121 "Accounting
for the Impairment of Long-Lived Assets", (SFAS No. 121). Management of the
Predecessor Company reviewed its long-lived assets, including goodwill, in
connection with adopting SFAS No. 121 and concluded, after considering the
Predecessor Company's projected levels of profitability based on the then
current expected market conditions, that certain long-lived assets (consisting
primarily of goodwill) were impaired and, accordingly, recorded a charge to
reflect this impairment.
 
(2) DESCRIPTION OF BUSINESS
 
     The Company provides electrical contracting services directly to end users
and, indirectly, by acting as a subcontractor for construction managers, general
contractors and other subcontractors. Services are provided to a broad range of
customers including corporations, municipalities and other governmental
entities, primarily in the Northeast and, to a lesser extent, in the Midwestern
and West Coast regions of the United States.
 
(3) ACCOUNTING POLICIES
 
PRINCIPLES OF PREPARATION
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
ACCOUNTING FOR CONTRACTS
 
     Earned revenues and cost of earned revenues represent the portion of the
contract price and the related cost recognized under the Company's accounting
policies for construction contracts.
 
     The Company recognizes earned revenues and costs using the percentage of
completion method based on the ratio of costs incurred to total estimated costs.
 
     Contract losses are provided for when they become known. In forecasting
ultimate profitability on certain contracts, estimated recoveries may be
included for work performed under customer change orders to contracts for which
firm prices have not yet been negotiated. Due to uncertainties inherent in the
estimation and performance processes, it is possible that completion costs,
including

                            COMSTOCK HOLDINGS, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
those arising from contract penalty provisions and final contract settlements,
will be revised in the near-term. Such revisions to costs and income are
recognized in the period in which the revisions are determined.
 
DEPRECIATION AND AMORTIZATION
 
     Equipment is depreciated principally on the straight-line method over the
estimated useful life. Leasehold improvements are amortized using the
straight-line method over the life of the lease.
 
INVENTORY
 
     Inventory is recorded at cost.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers cash and cash equivalents to include cash on hand and
temporary cash investments purchased with an original maturity of three months
or less.
 
INTERIM FINANCIAL STATEMENTS
 
     The unaudited financial statements included herein have been prepared,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission ("SEC"). In the opinion of management, the accompanying
unaudited financial statements reflect all adjustments necessary to present
fairly the financial position as of March 31, 1998 and the results of operations
and cash flows for the three months ended March 31, 1997 and 1998.
 
(4) INCOME TAXES
 
     In accordance with the terms of the Agreements, the Company and Group
elected to treat the sale of the Company under Section 338(h)(10) of the
Internal Revenue Code. The effect of this election eliminated the Company's
ability to use net operating loss carryforwards and certain other related tax
attributes generated prior to the Sale.
 
     Also as a result of this election and the terms of the Agreements, the
financial reporting basis of Holding's investment in the Predecessor Company is
less than its income tax reporting basis. Such difference may result in future
deductions for income tax purposes and, under Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes", is treated as a temporary
difference. The effect of this difference was recorded as a deferred tax asset
at the time of the Sale. Such temporary differences primarily relate to
long-term contracts and other reserves. The net deferred tax asset of
approximately $1,684,000 resulting from these differences increased the excess
of acquired net assets over cost by the same amount. Also, under the Agreements,
Group has indemnified the Company for all liabilities for income taxes and any
related litigation imposed on the Predecessor Company for any period prior to
the Sale.
 
     The Predecessor Company's results were included in the consolidated federal
income tax return of Spie. During 1996, the Company utilized a portion of its
net operating loss carryforwards ("NOLs") to eliminate its statutory federal
income tax provision. State and local returns were filed and the related
provisions recorded on a separate company basis.

     Retainages of approximately $4,045,000 and $4,388,000 at December 31, 1996
and 1997 are invested in U.S. government obligations and municipal bonds. These
securities are classified as held to maturity and are valued at cost which
approximates market value. The Company anticipates that 53% of all retainages at
December 31, 1997 will be collected within one year.
 
     Costs and estimated earnings in excess of billings on uncompleted contracts
arise when revenues have been recorded but the amounts cannot be billed under
the terms of the contracts. Such amounts are recoverable from customers upon
various measures of performance, including achievement of certain milestones,
completion of specified units or completion of the contract. The Company
anticipates that substantially all amounts, other than unanticipated additional
contract costs (see below), will be billed and collected within one year.
 
     The Company has recorded as costs and estimated earnings in excess of
billings on uncompleted contracts amounts that it seeks or will seek to collect
from customers or others for errors or changes in contract specifications or
design, contract change orders in dispute or unapproved as to both scope and
price, or other customer-related causes of unanticipated additional contract
costs (pending change orders and claims). These amounts are recorded at their
estimated net realizable value when realization is probable and can be
reasonably estimated. No profit is recognized on the

construction costs incurred in connection with these amounts. Pending change
orders and claims involve the use of estimates and it is reasonably possible
that revisions to the estimated recoverable amounts of recorded pending change
orders and claims may be made in the near-term. Claims made by the Company
involve negotiation and, in certain cases, litigation. The Company expenses such
costs as incurred, although it may seek to recover these costs as part of the
claim. The Company believes that it has established legal bases for pursuing
recovery of recorded claims and it is management's intention to pursue and
litigate these claims, if necessary, until a decision or settlement is reached.
 
     The Company is pursuing unanticipated additional contract costs on certain
completed contracts. Costs and estimated earnings in excess of billings on
uncompleted contracts includes unbilled revenues of approximately $2,200,000 and
$3,915,000 at December 31, 1996 and 1997, respectively, related to these
contracts. In addition, billed accounts receivable and retainages include
contractually billed amounts related to these contracts of approximately
$1,600,000 and $2,257,000 at December 31, 1996 and 1997, respectively. Certain
contractually billed amounts related to these contracts may not be paid by the
customer to the Company until final resolution of the contract. The Company has
established reserves of approximately $2,200,000 and $2,285,000 related to
unbilled revenues at December 31, 1996 and 1997, respectively.

(a)  On April 4, 1997, the Company entered into a secured revolving credit
     agreement (the "Revolver") with a maximum aggregate principal amount of
     $15,000,000 (the "Commitment"). The Revolver expires December 31, 1999.
     Loans under the Revolver may be Base Rate or Eurodollar loans. Interest on
     Base Rate loans is at a rate of 1% plus the Base Rate, as defined,
     (approximately the prime rate); interest on Eurodollar loans is at 3.25%
     plus the Eurodollar Rate, as defined, (approximately LIBOR). An annual
     facility fee of 1% and a commitment fee of 1/2 of 1% is payable on the
     total Commitment and the total unused Commitment, respectively. Up to
     $10,000,000 of letters of credit may be drawn against the Commitment,
     $2,911,655 of which was drawn at December 31, 1997.
(b)  On December 11, 1997, the Company entered into a short-term secured
     revolving credit agreement (the "Temporary Revolver") with a maximum
     principal amount of $2,000,000. The Temporary Revolver expires on April 30,
     1998. Interest on the unpaid principal is at a rate of 2% plus the Base
     Rate (approximately prime rate).
(c)  Interest on this agreement is payable semi-annually at the rate of 8.5% and
     the principal is due in 1998.
 
     The Revolver and the Temporary Revolver are secured by substantially all
the assets of the Company and are guaranteed by Holdings and certain of its
shareholders. The Revolver and Temporary Revolver contain restrictive covenants
that, among other things, impose limitations on the Company with respect to its
ability to incur additional indebtedness, make certain investments, sell assets
or pay dividends. The Revolver and the Temporary Revolver also contain various
financial covenants which require the Company to meet certain targets including,
but not limited to, the maintenance of tangible net worth, a current ratio, a
debt to equity ratio and quarterly earnings before interest, taxes and
depreciation (EBITDA). The most restrictive of these convenants is the
requirement of a minimum of $750,000 of EBITDA per quarter.
 
(7) EMPLOYEE BENEFIT PLANS
 
     Group sponsored a qualified employee incentive savings plan which was
assumed by Holdings. Under the plan, nonunion employees who have completed one
year of service could elect to contribute to the plan from 1% to 15% of their
compensation. The Company makes a base contribution to the plan equal to 2% of
covered payroll and a partial matching contribution (as defined) not to exceed
4% of a participant's covered payroll. The Company's expense for contribu-

tions under the plan was approximately $342,000, $337,000, and $321,000 during
1995, 1996, and 1997, respectively.
 
     Prior to the Sale, the Company was generally self-insured for its
automobile and general liability insurance and, to a lesser extent, for workers'
compensation. Included primarily in accrued payroll and related withholdings at
December 31, 1996 and 1997 are reserves of $5,419,000 and $3,574,000,
respectively, relating to these insurance liabilities. The Company currently
participates in a paid indemnity plan for these insurance coverages.
 
     The Company sponsored an unfunded, fully insured postretirement medical
plan covering eligible retirees and their dependents which it elected to
terminate effective December 31, 1997. In 1995 and 1996 the Company offered, at
group rates, comprehensive medical care benefits to retirees and their covered
dependents. The Company contributed approximately one-half of the total premium
medical cost. Under the plan, employees were eligible to enroll on the first day
of the month following retirement from the Company after age 55 and ten years of
service. Upon adoption of Financial Accounting Standard No. 106, "Employers'
Accounting for Postretirement Benefits other than Pensions" the accumulated
postretirement benefit obligation was $943,000. This amount was amortized over
20 years.
 
     The postretirement benefit cost for 1995 and 1996 included the following

     The assumed discount rate used to measure the accumulated postretirement
benefit obligation was of 7.25% in 1995 and 1996. The assumed health care cost
trend rate was 10% and 9.5% in December 31, 1995 and 1996, respectively
gradually decreasing to an ultimate rate of 5% in 2004 for participants under
age 65. For those above age 65, 8% was used in 1995 and 7.5% in 1996, gradually
decreasing to an ultimate rate of 5% in 2004. A one percent increase in the
assumed health care cost trend rate would increase costs by $24,000 and $25,000
in 1995 and 1996 respectively. The accumulated postretirement benefit obligation
would increase by approximately $194,000 and $158,000 in 1995 and 1996,
respectively. This plan was discontinued in 1997.
 
     The Company has nonqualified defined benefit plans covering certain current
and former employees which provide benefits based on years of service and
compensation. In aggregate, at

     As inducement for entering into a new lease agreement for office space in
1994, the Predecessor Company was granted a tenant work allowance of
approximately $1,138,000. Such allowance was included in other liabilities and
was amortized on a straight-line basis over the term of the lease. The
unamortized balance at December 31, 1996 was $930,000. Such balance was written
off in 1997 as part of the purchase accounting adjustments in the acquisition of
the Predecessor Company. Rental expense for 1995, 1996, and 1997, including
amounts charged to cost of earned revenues, was approximately $3,710,000,
$3,527,000, and $2,685,000.
 
     The Company's performance under certain construction contracts is secured
by performance bonds for which the Company pays a separate fee.
 
(9) LEGAL MATTERS
 
     The Company is party to various legal actions, arising in the normal course
of business and including matters related to construction contract claims, some
of which involve substantial sums. The Company believes that the disposition of
all such actions, individually or in the aggregate, will not have a material
adverse effect on the consolidated financial position or results of operations
of the Company taken as a whole.
 
(10) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following disclosure of estimated fair value of financial instruments
is made in accordance with the requirements of SFAS No. 107, "Disclosures about
Fair Value of Financial Instruments." The estimated fair value amounts have been

business of railroad track construction, maintenance, salvage and related sales
primarily in the Pacific Northwest. The majority of construction and maintenance
work is performed under fixed price contracts. The duration of the Company's
contracts is typically less than one year.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE AND CONTRACT COST RECOGNITION
 
     The Company recognizes revenues from fixed-fee contracts using the
percentage-of-completion method, measured by the percentage of contract cost
incurred to date to management's estimated total cost for each contract.
Management considers comparison of costs incurred to date to total cost to be
the best available measure of progress on the contracts. Changes in job
performance, job conditions and estimated profitability may result in revisions
to total expected project costs and the anticipated gross profit and are
recognized in the period in which determined.
 
     Revenues from time-and-material contracts are recognized as the work
progresses.
 
     Contract costs include all direct material, labor and equipment costs and
those indirect costs related to contract performance and are charged to expense
as incurred. Provisions for estimated losses on uncompleted contracts are made
in the period in which such losses are determined.
 
     The asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts", represents revenues recognized in excess of amounts
billed. The liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts", represents billings in excess of revenues recognized.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers cash and cash equivalents to include cash on hand and
temporary cash investments purchased with an original maturity of three months
or less.
 
FINANCIAL INSTRUMENTS AND CREDIT RISK
 
     The Company operates primarily in the Pacific Northwest. As such, the
Company's revenues and related accounts receivable are principally from the same
geographic region. The terms of the sales give rise to unsecured accounts
receivable, as is common industry practice.
 
INVENTORY
 
     Inventory consists principally of stored rails, ties and other track
materials ("OTM") and parts to be used for contracts or resale and are stated at
the lower of cost or market. Market is based on estimated proceeds expected to
be obtained upon ultimate sale.
 
     The Company's principal method of acquiring inventory items is through
salvage operations. Items acquired through salvage operations are valued based
on costs incurred to acquire the items, including payments to third parties,
direct labor and other direct contract costs, and those indirect costs related
to contract performance. These costs are netted with any third party payments
received for the salvage operations. The Company compares total cost of salvaged
materials to market for rails, ties and OTM recovered and adjustments are made
if the calculated market value is less than the total salvage cost. In addition,
the Company evaluates amounts held in inventory and adjusts for rails, ties and
OTM quantities that exceed anticipated usage.

</TABLE>
 
     The Company has salvaged and recorded at cost $195,431 of inventory which
is comprised of various mine equipment, small locomotives and other items. The
Company believes it will realize amounts recorded upon disposition.
 
PLANT AND EQUIPMENT
 
     The Company records plant and equipment at cost. Depreciation is computed
using the straight-line method over the estimated useful life of the asset as
follows:
 
<TABLE>

Vehicles...................................................    5 - 7 years
Office furniture and equipment.............................        5 years
</TABLE>
 
     As assets are retired or otherwise disposed of, the cost and accumulated
depreciation are eliminated from their respective accounts and any gain or loss
is reflected in net income.
 
     Maintenance, repairs and minor replacements are expensed as incurred and
were $179,343 in 1995, $256,727 in 1996, and $353,428 in 1997.
 
INVESTMENTS -- LAND
 
     The Company has recorded $114,700 in accounts payable and accrued expenses
in the Balance Sheets related to amounts owed for materials recovered during a
1993 salvage operation. Included in this salvage operation was land acquired for
$20,800. Upon satisfaction of the obligation for the salvaged materials, clear
title will be presented to the Company by the seller for the land.
 
INCOME TAXES
 
     The Company operates as a sub-chapter S corporation. Accordingly, the
income taxes for the earnings of the Company are the responsibility of the
owners; therefore, these financial statements do not reflect any current or
deferred federal or state income taxes for the Company.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could vary from the estimates that were assumed
in preparing the financial statements.

related party in the Balance Sheets and are $12,788 and $10,000 as of December
31, 1996 and 1997, respectively.
 
     In 1995, the Company transferred a building and related leasehold
improvements to C. B. Enterprises, a related party, in exchange for a reduction
in amounts owed by the Company to C. B. Enterprises. No gain or loss was
recognized on this transaction. For purposes of the Statements of Cash Flows,
this transfer of approximately $120,000, net, has been treated as a noncash
transaction.
 
     No other material related party transactions have occurred.
 
9. PROFIT SHARING PLAN
 
     The Company has adopted a profit-sharing plan (the Plan) covering all full
time employees with one year of service. Participants become fully vested after
six years of service. Contributions made to the Plan for the years ended
December 31, 1995, 1996 and 1997, were $5,000, $50,000 and $100,000,
respectively.
 
10. DEFERRED COMPENSATION PAYABLE
 
     In 1993, the Company and one of its officers entered into a discretionary
deferred compensation agreement. The deferred compensation was to be payable to
the officer 90 days following the date on which he gives written notification to
Condon Brothers, Inc. of his retirement from the Company. During 1995, the
Company made the decision to suspend the agreement. At December 31, 1996 and
1997, the Company has an $85,410 and an $82,910 deferred compensation liability,
respectively, to the officer which will be paid to him upon his retirement. The
amount charged to operations was $30,000 for 1995 and zero for 1996 and 1997.
 
11. CASH SURRENDER VALUE OF LIFE INSURANCE
 
     The Company maintains life insurance policies on two officers. The face
value of these policies was $300,000 each at December 31, 1996 and 1997. The
cash surrender value on these policies was $20,411 and $28,338 as of December
31, 1996 and 1997, respectively.
 
12. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following estimated fair values of financial instruments are provided
pursuant to the requirements of Statement of Financial Accounting Standards No.

Value of Financial Instruments." The estimated fair value amounts have been
determined by the Company using available market information and appropriate
valuation methodologies.
 
ACCOUNTS RECEIVABLE AND ACCOUNTS PAYABLE
 
     The carrying amounts of these items at December 31, 1996 and 1997, are a
reasonable estimate of their fair value due to their short-term and liquid
nature.
 
LONG-TERM DEBT
 
     The carrying amount of the line of credit facility approximates fair value
as the interest rate fluctuates with changes in market conditions. It is
estimated that the fair value of the long-term debt is approximately market.
Management estimated the fair value of the long-term debt based on the remaining
term to maturity and a comparison of their current interest rates to market
rates for similar obligations.
 
13. CONTINGENCIES
 
     The Company is engaged in various lawsuits arising in the ordinary course
of business. In the opinion of management, based upon the advice of counsel, the
ultimate outcome of these lawsuits will not have a material adverse impact on
the Company's financial position, operations or liquidity.
 
     The Company has accrued $120,000 in accounts payable and accrued expenses
in the Balance Sheets associated with a 1997 railroad salvage contract. The
total amount of the salvage contract was originally $174,000. Due to a reduction
in the amount of rail, ties and OTM allowed to be salvaged, the Company is
presently in negotiations to have the contract obligation reduced. If the
Company is unsuccessful in obtaining a change-order for the contract, an
additional cost of $54,000 will be recognized in the financial statements as
inventory to the extent the value is supported by comparison to the Company's

     We have audited the accompanying balance sheets of CPI Concrete Products
Incorporated, as of January 31, 1997 and 1998, and the related statements of
earnings and retained earnings and cash flows for the years ended January 31,
1996, 1997 and 1998. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of CPI Concrete Products
Incorporated, as of January 31, 1997 and 1998, and the results of its operations
and its cash flows for the years ended January 31, 1996, 1997 and 1998, in
conformity with generally accepted accounting principles.

     These statements reflect the accrual basis of accounting which requires
recognition of revenues when earned and expenses when incurred without regard to
the exchange of each.
 
     Property, plant and equipment are stated at cost. Depreciation is provided
on the straight-line and declining balance methods over the estimated useful
lives of the various assets. Lives used for calculating depreciation are:
buildings 15-20 years and machinery and equipment 3-10 years. Amortization of
loan costs is made over a 120 month period.
 
     Expenditures for maintenance, repairs and minor renewals are expenses as
incurred; expenditures for improvements, replacements and major renewals are
capitalized. Assets retired, or otherwise disposed of, are eliminated from the
asset accounts along with related amounts of accumulated depreciation. Any gains
or losses from disposals are included in income.
 
     The Company has adopted Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes", which requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns. Under this
method, deferred tax liabilities and assets are determined based on the
difference between the financial statement and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse (see Note 5).
 
     As of January 31, 1997, and 1998 the Company has deposits in a financial
institution which exceed the FDIC insured limit by $82,372, and $421,898,
respectively.
 
     For the purposes of the statement of cash flows, the Company considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
 
     Amortizable assets are recorded at cost. Amortization is calculated by the
straight-line method over a 5 year life. Amortization expense for the years
ended, January 31, 1996, 1997 and 1998 was $2,625, $2,625 and $2,625,
respectively.
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires the use of management estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period.

NOTE 6. -- EMPLOYEE BENEFIT PLANS
 
     In 1986, the Company established an Employee Stock Ownership Plan (ESOP) to
provide additional retirement benefits to employees. The vesting provisions of
the ESOP trust instrument are based on vesting years of service. A participant
will always be 100% vested at normal retirement age. At January 31, 1996, 1997
and 1998 the ESOP owned 253 shares of the Company's common stock at a cost of
$212,995. Contributions by the Company to the ESOP for the years ended January
31, 1996, 1997 and 1998 totaled $40,000, $10,000 and $1,000, respectively.
 
     In June 1996, the Company adopted a 401(k) plan covering substantially all
employees who have met the minimum age requirements and who have completed one
year of continuous service. The Company's contribution is equal to 50% of each
participant's contribution of up to 3% of salary. Contributions totaled $0,
$29,509, and $41,460 for the years ended January 31, 1996, 1997 and 1998,
respectively.

statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on

reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of H.P. McGinley, Incorporated

                         NOTES TO FINANCIAL STATEMENTS
 
1. NATURE OF BUSINESS
 
     H.P. McGinley, Inc. (the "Company"), a Pennsylvania corporation, operates
as a manufacturer of specialty hardwood products, including railroad ties and
shipping materials. The Company services customers in Pennsylvania and
surrounding states.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
YEAR-END
 
     In 1997, the Company changed its financial reporting year-end to December
31. These financial statements reflect the results of operations for the years
ended February 29, 1996 and February 28, 1997 and the ten months ended December
31, 1997.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could vary from the estimates that were assumed
in preparing the financial statements.
 
REVENUE AND COST RECOGNITION
 
     The Company recognizes revenue when products are delivered to customers
pursuant to shipping agreements. Cost of goods sold includes the raw materials
cost and costs of producing the product, including milling and preservative
treatment.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers cash and cash equivalents to include cash on hand and
temporary cash investments purchased with an original maturity of three months
or less.
 
FINANCIAL INSTRUMENTS AND CREDIT RISK
 
     The Company operates primarily in the northeast United States. As such, the
Company's accounts receivable are from the same geographic region. In addition,
the Company's customers are primarily in the railroad/railroad construction
business or the transportation business. The terms of the sales give rise to
unsecured accounts receivable, as is common industry practice.
 
INVENTORY
 
     Inventory, consisting principally of raw materials and finished goods, is
stated at the lower of cost (first-in, first-out (FIFO)) or market.
 
PROPERTY, PLANT AND EQUIPMENT
 
     The Company records property, plant and equipment at cost. Depreciation is
computed using the straight-line and accelerated methods over the estimated
useful lives of the assets as follows:
 
<TABLE>
<S>                                                         <C>
Buildings and improvements................................  15 to 30 years
Machinery and equipment...................................    5 to 7 years
Office furniture and equipment............................    5 to 7 years
Transportation equipment..................................    5 to 7 years

                          H.P. MCGINLEY, INCORPORATED
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     As assets are retired or otherwise disposed of, the cost and accumulated
depreciation are eliminated from the accounts, and any gain or loss is reflected
in net income. Normal maintenance and repairs are charged to expense as
incurred; major renewals or betterments which extend the life or increase the
value of assets are capitalized.
 
INCOME TAXES
 
     The provision for income taxes is based on earnings reported by the
Company. In accordance with Statement of Financial Accounting Standards ("SFAS")
No. 109, a deferred income tax asset or liability is determined by applying
currently enacted tax laws and rates to the expected reversal of the cumulative
temporary differences between the carrying value of assets and liabilities for
financial statement and income tax purposes.
 
INTERIM FINANCIAL INFORMATION
 
     The unaudited financial statements included herein have been prepared,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission ("SEC"). In the opinion of management, the accompanying
unaudited financial statements reflect all adjustments necessary to present
fairly the financial position as of March 31, 1998 and the results of operations
and cash flows for the three months ended February 28, 1997 and March 31, 1998.
 
3. INVENTORIES
 
     The principal components of inventories are as follows:

</TABLE>
 
4. EMPLOYEE BENEFIT PLANS
 
     The Company had a defined benefit pension plan (the "Plan") for all
employees meeting certain age and length of service requirements. Benefits were
based primarily on years of service and average annual compensation during the
highest five consecutive years. In fiscal 1997, the Company terminated the Plan
and distributed vested benefits in accordance with ERISA requirements. The
Company made a contribution of $25,000 during the year ended February 29, 1996
and a final contribution to the Plan of $26,377 during the year ended February
28, 1997.
 
     The Company maintains a defined contribution benefit plan which covers
substantially all eligible employees. Contributions to the defined contribution
benefit plan during the years ended February 29, 1996 and February 28, 1997 and
the ten months ended December 31, 1997 amounted to $8,865, $40,922 and $0,
respectively.
 
5. INCOME TAXES
 
     Under the asset and liability method of SFAS 109, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. Under SFAS
 
                                      F-66

109, the effect on deferred tax assets and liabilities of a change in tax rates
is recognized in income in the period that includes the enactment date.

     The carrying amounts of these items are a reasonable estimate of their fair
value due to their short-term nature.
 
9. SIGNIFICANT CUSTOMERS
 
     A significant portion of the Company's sales were to one unaffiliated
customer. Amounts due from this customer represented 25% of the total accounts
receivable at December 31, 1997 and 14% of sales for the period then ended. The
loss of this customer would have a material effect on the Company's business if
this loss was not offset by additional business from other sources.
 
10. SUBSEQUENT EVENT (UNAUDITED)
 
     On May 21, 1998, the stockholders of the Company entered into an Agreement
and Plan of Reorganization (the "Agreement") with RailWorks Corporation. Under
the terms of the Agreement, the stockholders will exchange their stock of the
Company for cash and stock of RailWorks Corporation. The transaction is expected
to be completed in August 1998.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Kennedy Railroad Builders, Inc.:
 
     We have audited the accompanying combined balance sheets of KENNEDY
RAILROAD BUILDERS, INC. (a Pennsylvania corporation) AND ASSOCIATED COMPANIES
(collectively, the "Company") as of March 31, 1997 and December 31, 1997, and
the related combined statements of operations, stockholders' equity and cash
flows for the years ended March 31, 1996 and 1997 and the nine month period
ended December 31, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of Kennedy
Railroad Builders, Inc. and Associated Companies as of March 31, 1997 and
December 31, 1997, and the results of their operations and their cash flows for
the years ended March 31, 1996 and 1997 and the nine months ended December 31,
1997 in conformity with generally accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND NATURE OF BUSINESS
 
     The accompanying combined financial statements include the accounts of
Kennedy Railroad Builders, Inc. ("Kennedy"), Railcorp, Inc. ("Railcorp") and
Alpha-Keystone Engineering, Inc. ("Alpha") (collectively, referred to as the
"Company"). Each of these companies are subject to common control and are
presented on a combined basis.
 
     The Company operates as a contractor, constructing, repairing and
maintaining railroad tracks for private and government customers located
throughout the northeastern region of the United States. The work is performed
under various forms of contracts, including fixed-fee and time-and-material
contracts.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
YEAR-END
 
     In 1997, the Company changed its financial reporting year-end to December
31. These combined financial statements reflect the results of operations for
the years ended March 31, 1996 and 1997 and the nine months ended December 31,
1997.
 
COMBINATION POLICIES
 
     The Company includes the combined accounts of three companies subject to
common control. All significant transactions between the three companies are
eliminated in combination. Alpha was incorporated in February 1996. The results
for Alpha for the period from inception to March 31, 1997 are included in the
Company's financial statements for the year ended March 31, 1997.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could vary from the estimates that were assumed
in preparing the financial statements.
 
REVENUE AND COST RECOGNITION
 
     The Company recognizes revenues from fixed-fee contracts using the
percentage-of-completion method, measured by the percentage of cost incurred to
date to management's estimated total cost for each contract. That method is used
because management considers total cost to be the best available measure of
progress on the contracts. Changes in job performance, job conditions and
estimated profitability may result in revisions to cost and income, which are
recognized in the period in which the revisions are determined.
 
     Revenues from time-and-material contracts are recognized currently as the
work is performed.
 
     Contract costs include all direct material, labor and equipment costs and
those indirect costs related to contract performance and are charged to expense
as incurred. Provisions for estimated losses on uncompleted contracts are made
in the period in which such losses are determined.
 
     The asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts", represents revenues recognized in excess of amounts
billed. The liability, "Billings in excess of
 
                                      F-74

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
costs and estimated earnings on uncompleted contracts", represents billings in
excess of revenues recognized.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers cash and cash equivalents to include cash on hand and
temporary cash investments purchased with an original maturity of three months
or less.
 
FINANCIAL INSTRUMENTS AND CREDIT RISK
 
     The Company operates primarily in the northeastern region of the United
States. As such, the Company's accounts receivable are from the same geographic
region. The terms of the sales give rise to unsecured accounts receivable, as is
common industry practice.
 
INVENTORIES
 
     Inventories, consisting principally of stored materials and parts to be
used for contracts, are stated at the lower of cost or market. Cost is
determined by the first-in, first-out (FIFO) method.
 
PROPERTY, PLANT AND EQUIPMENT
 
     The Company records property, plant and equipment at cost. Depreciation is
computed using the straight-line and the accelerated methods over the estimated
useful life of the asset as follows:
 
<TABLE>
<S>                                                       <C>
Buildings...............................................       39 years
Machinery and equipment.................................    3 - 7 years
Office furniture and equipment..........................    5 - 8 years
Leasehold improvements..................................  31 - 39 years
</TABLE>
 
     As assets are retired or otherwise disposed of, the cost and accumulated
depreciation are eliminated from the accounts, and any gain or loss is reflected
in net income. The cost of maintenance and repair is charged to income as
incurred. Significant renewals and betterments are capitalized and depreciated
over the assets remaining useful life.
 
INCOME TAXES
 
     The provision for income taxes is based on earnings reported by the
Company. In accordance with Statement of Financial Accounting Standards ("SFAS")
No. 109, a deferred income tax asset or liability is determined by applying
currently enacted tax laws and rates to the expected reversal of the cumulative
temporary differences between the carrying value of assets and liabilities for
financial statement and income tax purposes.
 
     Kennedy and Railcorp are both C corporations for Federal income tax
purposes. Alpha is a S corporation. As a result, the income of the Alpha is not
taxed at the corporate level. For purposes of the accompanying financial
statements, Alpha has been treated as a C corporation and income taxes have been
provided at the statutory rate and recorded using the provisions of SFAS No.
109.
 
INTERIM FINANCIAL STATEMENTS
 
     The unaudited financial statements included herein have been prepared,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission ("SEC"). In the opinion of management, the accompanying
unaudited financial statements reflect all adjustments

satisfactory settlement of certain contingencies) in fiscal 1997. The total
proceeds of $547,364 were reduced by expenses of the transaction totaling

shareholders and employees of the Company that were primarily responsible for
this transaction.

9. INCOME TAXES
 
     In accordance with SFAS No. 109, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates expected to apply to taxable income in the years in
which those temporary differences are expected to be recovered or settled. Under
SFAS 109, the effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.

CASH, ACCOUNTS RECEIVABLE AND ACCOUNTS PAYABLE
 
     The carrying amounts of these items are a reasonable estimate of their fair
value due to their short-term nature.
 
LONG-TERM DEBT
 
     The carrying amount of the line of credit facility approximates fair value
as the interest rate fluctuates with changes in market conditions. The carrying
value of other loans relating to real estate, vehicles and equipment approximate
fair value as the interest rates are comparable to market rates today.

                         NOTES TO FINANCIAL STATEMENTS
 
1. NATURE OF BUSINESS
 
     Merit Railroad Contractors, Inc. (the "Company"), a Missouri corporation
operates as a construction contractor, constructing, repairing and maintaining
railroad tracks for private and government customers located throughout
Illinois, Kentucky, Missouri, Tennessee and Wisconsin. The work is performed
under various forms of contracts, including fixed-fee, unit-price and time-
and-material contracts. The length of the contracts vary, but is typically less
than one year.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could vary from the estimates that were assumed
in preparing the financial statements.
 
REVENUE AND COST RECOGNITION
 
     The Company recognizes revenues from fixed-fee contracts using the
percentage-of-completion method, measured by the percentage of cost incurred to
date to management's estimated total cost for each contract. This method is used
because management considers total cost to be the best available measure of
progress on the contracts. Changes in job performance, job conditions and
estimated profitability may result in revisions to cost and income, which are
recognized in the period in which the revisions are determined.
 
     Revenues from time-and-material contracts are recognized as the work is
performed.
 
     Contract costs include all direct material, labor and equipment costs and
those indirect costs related to contract performance and are charged to expense
as incurred. Provisions for estimated losses on uncompleted contracts are made
in the period in which such losses are determined.
 
     The asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts", represents revenues recognized in excess of amounts
billed. The liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts", represents billings in excess of revenues recognized.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers cash and cash equivalents to include cash on hand and
temporary cash investments purchased with an original maturity of three months
or less.
 
FINANCIAL INSTRUMENTS AND CREDIT RISK
 
     The Company operates primarily in Illinois, Kentucky, Missouri, Tennessee
and Wisconsin. As such, the Company's accounts receivable are from the same
geographic region. The Company's customers are not concentrated in any specific
industry group. Although the Company limits its credit risk by exercising lien
rights when available, terms of the majority of sales give rise to unsecured
accounts receivable, as is common industry practice.
 
     During the years ended December 31, 1995, 1996 and 1997, one customer
accounted for 11% of revenue, one customer accounted for 37% of revenue and one
customer accounted for 11% of revenue, respectively.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
INVENTORIES
 
     Inventories, consisting principally of stored materials and parts to be
used for contracts, are stated at the lower of cost or market. Cost is
determined by the first-in, first-out (FIFO) method.
 
PROPERTY AND EQUIPMENT
 
     The Company records property and equipment at cost. Depreciation is
computed using the straight-line and the declining-balance method over the
estimated useful lives of the assets as follows:
 
<TABLE>
<S>                                         <C>
Machinery and equipment...................                         5-7 years
Automobiles and trucks....................                           5 years
Office furniture and equipment............                         5-7 years
Leasehold improvements....................  Lesser of 5 years or lease terms
</TABLE>
 
     As assets are retired or otherwise disposed of, the cost and accumulated
depreciation are eliminated from the accounts, and any gain or loss is reflected
in other income.
 
ASSET IMPAIRMENT
 
     If facts and circumstances suggest that a long-lived asset may be impaired,
the carrying value is reviewed. If this review indicates that the value of the
asset will not be recoverable, as determined based on projected undiscounted
cash flows related to the asset over its remaining life, then the carrying value
of the asset is reduced to its estimated fair value.
 
OTHER INCOME (EXPENSE)
 
     Other income (expense) includes gain and loss on disposition of property
and equipment, sale of scrap and other miscellaneous income and expense, all of
which are not directly related to the Company's primary business. During 1997,
the Company incurred $107,000 of costs related to the movement of inventory and
equipment from an old location to a new location.
 
INCOME TAXES
 
     The Company operates as a sub-chapter S corporation. Accordingly, the
income taxes are the responsibility of the owners; and the accompanying
financial statements do not reflect any federal or state income taxes for the
Company.
 
     The Company uses different methods of accounting for tax and financial
reporting. The primary difference relates to the use of the accrual basis for
financial reporting and the cash basis for tax reporting.
 
INTERIM FINANCIAL STATEMENTS
 
     The unaudited financial statements included herein have been prepared,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission ("SEC"). In the opinion of management, the accompanying
unaudited financial statements reflect all adjustments necessary to present
fairly the financial position as of March 31, 1998 and the results of operations
and cash flows for the three months ended March 31, 1997 and 1998.

established pursuant to the Internal Revenue Code. The Company's contribution to
the 401(k) Plan is discretionary and determined annually by the Board of
Directors. The Company contributed $30,000, $-0-and $-0- to the 401(k) Plan for
the years ended December 31, 1995, 1996 and 1997, respectively.
 
     The Company also maintains a Money Purchase Plan whereby mandatory

9. RELATED PARTY TRANSACTIONS
 
     The Company's office and storage yard in St. Louis are leased from an
affiliated company under a five year lease that expires in June 2001, with
monthly payments of $4,100. In addition to the minimum rent, the Company is
required to pay a percentage rent amount equal to 1% of gross receipts in excess
of $6,100,000. The amount of rent charged to operations was $58,700 and $57,200
for the years ended December 31, 1996 and 1997, respectively. There was no such
lease agreement in 1995. The Company also leases certain equipment from another
affiliated entity on a month-to-month basis and was charged $71,200, $89,800 and
$181,500 during 1995, 1996 and 1997, respectively.
 
     The payable to affiliate arose in 1996 and is payable on demand. No
interest is due on the note.
 
10. COMMITMENTS AND CONTINGENCIES
 
LITIGATION
 
     The Company is engaged in various lawsuits arising in the ordinary course
of business. In the opinion of management, based upon the advice of legal
counsel, the ultimate outcome of these lawsuits will not have a material adverse
impact on the Company's financial position or results of operations.
 
CONTINGENCY
 
     The Company completed a contract during 1995 on which a dispute arose with
a subcontractor to the job. The subcontractor has indicated additional charges
are due as a result of work performed over the amounts due under its original
contract with the Company. Specifically, the subcontractor alleges the
engineering firm contracted by the Company's customer grossly underestimated the
amount of excavation work required at the job site. Although no evaluation of
the threatened litigation can be determined at this time, management believes
the Company's exposure for monetary damages should be minimal due to the fact
that the subcontractor's claims are essentially against the Company's customer
and the customer's engineering firm. At December 31, 1996 and 1997, the Company
was owed $81,000 from its customer that is being withheld pending resolution of
the dispute and owed its subcontractor $38,053 in connection with the original
contract terms. An allowance of $40,000 has been specifically provided for the
potential uncollectibility of amounts due from the customer.
 
11. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts of cash, accounts receivable and accounts payable are
a reasonable estimate of their fair value due to their short-term nature.
 
     The carrying amount of the line of credit facility approximates fair value
as the interest rate fluctuates with changes in market conditions. The carrying
amount of long-term debt approximates fair value.
 
12. SUBSEQUENT EVENT (UNAUDITED)
 
     On May 21, 1998, the stockholders of the Company entered into an Agreement
and Plan of Reorganization (the "Agreement") with RailWorks Corporation. Under
the terms of the Agreement, the stockholders will exchange their stock of the
Company for cash and stock of RailWorks Corporation. The transaction is expected
to be completed in August 1998.

To Midwest Construction Services, Inc.:
 
     We have audited the accompanying balance sheets of MIDWEST CONSTRUCTION
SERVICES, INC. ("the Company") (an Indiana corporation), as of December 31, 1996

cash flows for each of the three years ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Midwest Construction
Services, Inc. as of December 31, 1996 and 1997, and the results of its

                       NOTES TO THE FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
NATURE OF OPERATIONS
 
     Midwest Construction Services, Inc. (the "Company") operates as a
construction contractor, constructing, repairing and maintaining railroad tracks
primarily to steel processors throughout Northwest Indiana. The work is
performed under various forms of contracts, including fixed-fee and
time-and-material contracts.
 
REVENUE AND COST RECOGNITION
 
     The Company recognizes revenues from fixed-price construction contracts
using the percentage-of-completion method, measured by the percentage of cost
incurred to date to management's estimated total cost for each contract. That
method is used because management considers total cost to be the best available
measure of progress on the contracts. Changes in job performance, job conditions
and estimated profitability may result in revisions to cost and income, which
are recognized in the period in which the revisions are determined.
 
     Revenues from time-and-material contracts are recognized as the work is
performed.
 
     Contract costs include all direct material and labor costs and those
indirect costs related to contract performance. General and administrative costs
are charged to expense as incurred. Provisions for estimated losses on
uncompleted contracts are made in the period in which such losses are
determined.
 
     The asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts," represents billings in excess of revenues recognized.
 
USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could vary from the estimates that were assumed
in preparing the financial statements.
 
CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents, as reported on the accompanying balance sheets
and statements of cash flows, includes all amounts in non-interest-bearing
checking accounts and interest-bearing money market accounts.
 
FINANCIAL INSTRUMENTS AND CREDIT RISK
 
     The Company operates primarily in Northwest Indiana and primarily serves
the steel industry. As such, the Company's accounts receivable are from the same
geographic region. The terms of the sales give rise to unsecured accounts
receivable, as is common industry practice. The Company is dependent on the
steel industry and the economic trends that affect the steel industry.

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)
 
INVESTMENTS
 
     Management determines the appropriate classifications of securities at the
time of purchase. If management has the intent and the Company has the ability
at the time of purchase to hold securities until maturities or on a long-term
basis, they are classified as held to maturity securities and carried at
amortized historical cost. Securities to be held for indefinite periods of time
and not intended to be held to maturity or on a long-term basis are classified
as available for sale and carried at fair value.
 
     Realized gains and losses on dispositions are based on the net proceeds and
the amortized historical cost of the securities sold, using the specific
identification method. Unrealized gains and losses on available for sale
securities are based on the difference between book value and fair value of each
security. These gains and losses are credited or charged to stockholders'
equity, whereas realized gains and losses are reported on the Company's
statements of income.
 
INVENTORY
 
     Inventories are stated at the lower of cost or market. Cost is determined
by the first-in, first-out ("FIFO") method. Market is based on estimated net
realizable value.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment is recorded at cost. Depreciation is computed using
the straight-line and the accelerated method over the estimated useful life of
the asset as follows:
 
<TABLE>
<S>                                                           <C>
Autos and trucks............................................   5 years
Construction equipment......................................  5-7 years
Office equipment............................................  3-10 years
Leasehold improvements......................................   39 years
</TABLE>
 
     When assets are retired or otherwise disposed of, the cost and related
accumulated depreciation are removed from the accounts and any gain or loss is
reflected in net income. Maintenance and repairs are charged to income as
incurred; significant renewals and betterments are capitalized.
 
INCOME TAXES
 
     Effective April 1, 1991, the Company has elected to be taxed as an "S"
Corporation under the provision of Subchapter "S" of the Internal Revenue Code.
As such, the Corporation pays no income tax, and revenue and expenses pass
through to the shareholders who pay income taxes on the earnings at their
respective tax rates. Therefore, these financial statements do not reflect any
federal or state income taxes for the Company.

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)
 
11. COMMITMENTS AND CONTINGENCIES
 
LITIGATION
 
     In the ordinary course of business, the Company enters into contracts that
require the Company to provide general liability insurance coverage which names
their customer as the co-insured policyholder. In addition, some contracts
require that the Company indemnify their customers against certain legal claims
related to the contracted work the Company will perform. As a result, the
Company from time to time is involved in their customer's lawsuits and is
contingently liable for the outcome of such legal cases.
 
     In 1994, an accident occurred on a customer's property that resulted in the
death of two Company employees and the injury of two other Company employees.
Settlements have been achieved in the fatality cases which were funded by the
Company's insurance carriers and the customer. The two injured employees have
sued the customer. Though the Company is not party to these personal injury
suits, the customer has indicated that they may seek a contribution from the
Company toward any settlement.
 
     The Company is direct party to an uninsured personal injury suit resultant
from a 1994 accident at a customer location that occurred in proximity to where
the Company was working. The Company is vigorously defending this case and
believes that it has both adequate reserves and good defenses to any claim of
liability that may be asserted against it related to this personal injury case.
 
     The Company is involved in three other personal injury suits (one in which
the Company is direct party and two in which the Company is indirectly involved)
that are all covered by the Company's insurance policies.
 
     In the case of all known contingencies, the Company accrues a charge for a
loss when it is probable and the amount is reasonably estimable. Based on the
current available information, the Company believes that the established
reserves are adequate to cover all known contingencies and that future costs
related to these contingent liabilities will not have a material adverse effect
on the Company's financial statements.
 
12. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following estimated fair values of financial instruments is made in
accordance with the requirements of Statement of Financial Accounting Standards
No. 107, "Disclosure about Fair Value of Financial Instruments." The estimated
fair value amounts have been determined by the Company using available market
information and appropriate valuation methodologies.
 
CASH, ACCOUNTS RECEIVABLE AND ACCOUNTS PAYABLE
 
     The carrying amounts of these items are a reasonable estimate of their fair
value due to their short-term nature.
 
LINE-OF-CREDIT FACILITY
 
     The carrying amount of the line-of-credit facility approximates fair value
as the interest rate fluctuates with changes in market conditions.
 
13. SUBSEQUENT EVENT (UNAUDITED)
 
     On May 21, 1998, the stockholders of the Company entered into an Agreement
and Plan of Reorganization (the "Agreement") with RailWorks Corporation. Under
the terms of the Agreement, the stockholders will exchange their stock of the
Company for cash and stock of RailWorks Corporation. The transaction is expected
to be completed in August 1998.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors
New England Railroad Construction Company, Inc.
Bridgeport, Connecticut
 
     We have audited the accompanying balance sheets of New England Railroad
Construction Company, Inc. as of December 31, 1997 and February 28, 1997, and
the related statements of operations and shareholders' equity and cash flows for
the ten months ended December 31, 1997 and each of the two years in the period
ended February 28, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of New England Railroad
Construction Company, Inc. as of December 31, 1997 and February 28, 1997, and
the results of its operations and its cash flows for the ten months ended
December 31, 1997 and each of the two years in the period ended February 28,
1997, in conformity with generally accepted accounting principles.

1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
DESCRIPTION OF BUSINESS:
 
     The Company performs railroad repair and construction projects primarily
for state and city governments located in the Northeastern United States.
 
ESTIMATES AND ASSUMPTIONS:
 
     Management uses estimates and assumptions in preparing financial statements
in accordance with generally accepted accounting principles. Those estimates and
assumptions affect the reported amounts of assets and liabilities and the
reported revenue and expenses. Actual results could vary from the estimates that
were used.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     The carrying amounts of cash and cash equivalents, contract and retainage
receivable and accounts payable approximate fair value because of their
short-term nature. The carrying amount of long-term debt approximates fair value
based on the borrowing rates currently available to the Company for bank loans
with similar terms and maturities.
 
REVENUE AND COST RECOGNITION:
 
     Earnings on long-term construction contracts are recognized on the
percentage-of-completion method in the ratio of costs incurred to total
estimated costs. Earnings and costs on contracts are subject to revision
throughout the terms of the contracts; required adjustments are made in the
period revisions become known. Because of inherent uncertainties in estimating
costs, it is at least reasonably possible that the Company's estimates of costs
and revenues will change in the near term. Provisions are made for the full
amounts of anticipated losses when first determinable. Claims for additional
contract revenues are recognized at the point it is probable that the claim will
result in additional revenue and the amount can be estimated reliably.
 
     Balances billed but not paid according to retainage provisions under
construction contracts generally become due upon contract completion and
acceptance by the owners. Construction contracts normally are completed within
one to two years.
 
INVENTORY:
 
     Inventory, principally materials and supplies, is stated at the lower of
cost or net realizable value. Cost is determined by the first-in, first-out
(FIFO) method.
 
PROPERTY, PLANT AND EQUIPMENT:
 
     Property, plant and equipment is stated at cost. Depreciation is provided
principally by use of the straight-line method over the estimated useful life of
the related asset. Accelerated methods are used for income tax reporting
purposes.

                NEW ENGLAND RAILROAD CONSTRUCTION COMPANY, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
INCOME TAXES:
 
     Deferred income taxes are determined based on the difference between the
financial statement and income tax basis of assets and liabilities using tax
rates expected to be in effect in the years in which the differences are
expected to reverse. The temporary differences relate primarily to the reporting
of revenue recognition on long-term contracts, depreciation and net operating
loss carryforwards.
 
CASH AND CASH EQUIVALENTS:
 
     From time to time, the Company's cash balance with financial institutions
exceeds the maximum FDIC insured balance of $100,000. The Company has not
experienced any losses in such accounts and believes it is not exposed to any
significant credit risk on cash and cash equivalents.
 
     For the reporting of cash flows, the Company considers savings accounts and
certificate of deposits with original maturities of three months or less to be
cash and cash equivalents.
 
YEAR-END:
 
     In 1997, the Company changed its financial reporting year-end to December
31. These financial statements reflect the results of operations for the years
ended February 29, 1996 and February 28, 1997 and the ten months ended December
31, 1997.

3. CLAIMS:
 
     During the year ended February 28, 1997, the Company settled two claims for
$230,000. These claims represent additional costs incurred and profits lost by
the Company due to performing work out of sequence, drawing revisions and
specification changes by the project owners. The settlements are included in
contract and retainage receivables and earned revenue as of and for the year
ended February 28, 1997.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Railroad Service, Inc. and Minnesota Railroad Service, Inc.:
 
     We have audited the accompanying combined balance sheets of RAILROAD
SERVICE, INC. (a Nevada corporation) and MINNESOTA RAILROAD SERVICE, INC. (a
Tennessee corporation) as of December 31, 1996 and 1997, and the related
combined statements of operations, stockholders' equity and cash flows for each
of the three years in the period ended December 31, 1997. These combined
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these combined financial statements
based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of Railroad
Service, Inc. and Minnesota Railroad Service, Inc. as of December 31, 1996 and
1997, and the results of their combined operations and their combined cash flows
for the years then ended in conformity with generally accepted accounting
principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. NATURE OF BUSINESS
 
     Railroad Service, Inc. (RSI) and Minnesota Railroad Service, Inc. (MRSI)
(together the "Companies") operate as a construction contractor, constructing,
repairing and maintaining railroad tracks for private and government customers
located throughout the United States with concentrations of work primarily in
the upper midwest. The work is performed under various forms of contracts,
including fixed-fee and time-and-material contracts. The time period of the
contracts vary, but they are generally less than one year.
 
     The Companies have common ownership and share management personnel and
facilities. The combined statements of financial position, income and cash flows
are presented in these financial statements. All intercompany transactions and
balances have been eliminated.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could vary from the estimates that were assumed
in preparing the financial statements.
 
REVENUE AND COST RECOGNITION
 
     The Companies recognize revenues from fixed-fee contracts using the
percentage-of-completion method, measured by the percentage of cost incurred to
date to management's estimated total cost for each contract. That method is used
because management considers total cost to be the best available measure of
progress on the contracts. Changes in job performance, job conditions and
estimated profitability may result in revisions to cost and revenue, which are
recognized in the period in which the revisions are determined.
 
     Revenues from time-and-material contracts are recognized currently as the
work is performed.
 
     Contract costs include all direct material, labor, equipment costs and
those indirect costs related to contract performance which are charged to
expense as incurred. Provisions for estimated losses on uncompleted contracts
are made in the period in which such losses are determined.
 
CASH AND CASH EQUIVALENTS
 
     The Companies consider cash and cash equivalents to include cash on hand
and temporary cash investments purchased with an original maturity of three
months or less.
 
FINANCIAL INSTRUMENTS AND CREDIT RISK
 
     The Companies operate primarily in the upper midwestern region of the
United States. The Companies' accounts receivable are from the same geographic
region. The terms of the sales give rise to unsecured accounts receivable, as is
common industry practice. The Companies periodically assess collection of its
receivables and provide allowance for doubtful accounts as appropriate. No such
allowances were deemed necessary as of December 31, 1996 and 1997.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
CONCENTRATIONS OF CUSTOMERS
 
     Approximately 55% of accounts receivable at December 31, 1997 were with
four customers. In 1995 approximately 27% of revenues were earned from two
customers. In 1997 three customers accounted for approximately 40% of revenues.
 
MATERIAL ON HAND
 
     Material on hand principally consists of stored materials and parts to be
used for contracts and have been stated at the lower of cost or market. Cost is
determined by the first-in, first-out (FIFO) method.

     The Companies record property, plant and equipment at cost. Depreciation
and amortization is computed using the straight-line method over the estimated
useful life of the asset as follows:
 
<TABLE>
<S>                                                           <C>
Tools and equipment.........................................   4 - 7 years
Vehicles and trailers.......................................   4 - 7 years
Office equipment............................................  4 - 10 years
Leasehold improvements......................................  7 - 18 years
</TABLE>
 
     As assets are retired or otherwise disposed of, the cost and accumulated
depreciation and amortization are eliminated from the accounts, and any gain or
loss is reflected in net income.
 
INCOME TAXES
 
     The Companies operate as sub-chapter S corporations for Federal and certain
state income tax reporting purposes. Accordingly, the income taxes for the
earnings of the Companies are the responsibility of the owners. Therefore, these
financial statements do not reflect any Federal income taxes for the Companies.

Companies and related parties provide products and services to each other.
Transactions with related parties included in the combined financial statements
resulted in the recognition of approximately $14,900, $26,900 and $15,300 of
income and approximately $91,700, $86,400 and $72,400 of expense for the years
ended December 31, 1995, 1996 and 1997, respectively.
 
     Due from related parties consists of charges from the Companies to
affiliated companies for labor, equipment and administrative services.
 
11. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following estimated fair values of financial instruments is made in
accordance with the requirements of SFAS No. 107, "Disclosures about Fair Value
of Financial Instruments." The estimated fair value amounts have been determined
by the Companies using available market information and appropriate valuation
methodologies.
 
CASH, ACCOUNTS RECEIVABLE AND ACCOUNTS PAYABLE
 
     The carrying amounts of these items are a reasonable estimate of their fair
value due to their short-term nature.
 
LONG-TERM DEBT
 
     The line of credit facility approximates fair value as the interest rate
fluctuates with changes in market conditions. It is estimated that the carrying
amount of the long-term debt approximates market. Management estimated the fair
value of the long-term debt based on the remaining term to maturity and the
current interest rate environment as a market does not exist for the debt or
similar debt of the Companies.
 
12. SUBSEQUENT EVENTS (UNAUDITED)
 
     Effective January 2, 1998, the majority stockholder gifted 55 shares of
Railroad Service, Inc. stock and 5 shares of Minnesota Railroad Service, Inc.
stock to another shareholder. Accordingly, $399,651 was recorded as a charge to
compensation expense and a contribution of paid-in capital in the three months
ended March 31, 1998.
 
     On May 21, 1998, the stockholders of the Company entered into an Agreement
and Plan of Reorganization (the "Agreement") with RailWorks Corporation. Under
the terms of the Agreement, the stockholders will exchange their stock of the
Company for cash and stock of RailWorks Corporation. The transaction is expected
to be completed in August 1998.

                 SOUTHERN INDIANA WOOD PRESERVING COMPANY, INC.
 
                         NOTES TO FINANCIAL STATEMENTS
 
1. NATURE OF BUSINESS
 
     Southern Indiana Wood Preserving Company, Inc. (the "Company") (an Indiana
corporation) operates as a wood preserving company specializing in producing
pressure, creosote treated wood products for private and government customers
located throughout the United States, primarily in the Midwest.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could vary from those estimates.
 
REVENUE RECOGNITION
 
     The Company recognizes revenues at the time of shipment of goods.
 
FINANCIAL INSTRUMENTS AND CREDIT RISK
 
     The Company operates in Indiana. However, the Company's accounts receivable
include other geographic regions of the United States. The terms of the sales
give rise to unsecured accounts receivable, as is common industry practice.
During 1997, no single customer provided for greater than 10% of sales.
 
INVENTORY
 
     Inventory, consisting principally of trimmed and graded railroad ties, is
stated at the lower of cost or market. Cost is determined by the average cost
method.
 
PROPERTY, PLANT AND EQUIPMENT
 
     The Company records property, plant and equipment at cost. Depreciation is
computed using straight-line and accelerated methods over the estimated useful
lives of the assets as follows:
 
<TABLE>
<S>                                                          <C>
Buildings..................................................      25 Years
Machinery and equipment....................................  7 - 10 Years
Office furniture and equipment.............................  5 - 10 Years
Leasehold improvements.....................................      10 Years
</TABLE>
 
     As assets are retired or otherwise disposed of, the cost and accumulated
depreciation are eliminated from the accounts, and any gain or loss is reflected
in the statement of income.
 
INCOME TAXES
 
     The Company operates as an S corporation. Accordingly, the income taxes for
the earnings of the Company are the responsibility of the owner; therefore,
these financial statements do not reflect any Federal or state income taxes.

</TABLE>
 
     Total rental expense for 1997 was $9,119.

of credit has a limit of $2,000,000 and is secured by the Company's trade
receivables and inventories. The maturity date of the line of credit agreement

ordinary course of business.
 
     The Company is subject to certain Federal, state and local environmental
laws and regulations relating to the use of creosote. Creosote is used in the
Company's manufacturing process to treat the ties so that they can withstand
exposure to outside elements. Creosote, a coal tar treated derivative, has been
recognized by environmental regulating agencies as a hazardous material. The
Company currently believes that it is in compliance with the environmental laws
and regulations surrounding creosote. The Company has not been notified of any
violations of the regulations by regulatory agencies.

accordance with the requirements of Statement of Financial Accounting Standards
No. 107, "Disclosures About Fair Value of Financial Instruments." The carrying
value of receivables, accounts payable and the line of credit have been
determined by the Company to approximate their fair value using available market
information and appropriate valuation methodologies.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To U.S. Trackworks, Inc. and
Northern Rail Service and Supply Co.:
 
     We have audited the accompanying combined balance sheets of U.S.
TRACKWORKS, INC. AND NORTHERN RAIL SERVICE AND SUPPLY CO. (Michigan
corporations) as of December 31, 1996 and 1997, and the related combined
statements of operations, changes in stockholders' equity and cash flows for the
years then ended. These financial statements are the responsibility of the
Companies' management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of U.S. Trackworks,
Inc. and Northern Rail Service and Supply Co. as of December 31, 1996 and 1997,
and the results of their operations and their cash flows for the years then
ended in conformity with generally accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     U.S. Trackworks, Inc. (a Michigan corporation) operates as a construction
contractor, constructing, repairing and maintaining railroad tracks for private
and government customers located primarily in the Midwest United States. The
work is performed under various forms of contracts, including fixed-fee and
time-and-material contracts. Northern Rail Service and Supply Co. (a Michigan
corporation) operates in Michigan and provides maintenance services on railroad
tracks primarily under time-and-material contracts.
 
BASIS OF PRESENTATION
 
     These combined financial statements include the accounts and results of
operations of both U.S. Trackworks, Inc. and Northern Rail Service and Supply
Co., which are commonly owned. U.S. Trackworks, Inc. and Northern Rail Service
and Supply Co. are collectively referred to as the "Company." All significant
intercompany transactions and balances have been eliminated in combination.
 
CASH AND CASH EQUIVALENTS
 
     For purposes of the combined balance sheets and the combined statements of
cash flows, the Company considers cash and cash equivalents to include cash on
hand and highly liquid debt instruments with an original maturity of three
months or less.
 
INVENTORY
 
     Inventory, consisting principally of stored materials and parts to be used
for contracts, is stated at the lower of cost or market. Cost is determined by
the first-in, first-out (FIFO) method.
 
PROPERTY AND EQUIPMENT
 
     The Company records property and equipment at cost. Depreciation is
computed using the straight-line method over the estimated useful life of the
asset. Newly purchased equipment is depreciated over eight years and used
equipment is depreciated over five years. Repairs to existing equipment that
lengthen the asset's useful life are depreciated over three years.
 
     When assets are retired or otherwise disposed of, the cost and accumulated
depreciation are removed from the accounts and any gain or loss is reflected in
the combined statements of operations.
 
CONCENTRATION OF CREDIT RISKS
 
     The Company's credit risks primarily relate to cash and accounts
receivable. Cash is primarily held in bank accounts. Accounts receivable
represent amounts due from the Company's customers. The Company performs
continual credit evaluations of its customers and, from time to time, an
individual customer's accounts receivable balance may represent a significant
portion of the Company's total accounts receivable balance. At December 31,
1997, one customer accounted for approximately 36% of the accounts receivable
balance.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
REVENUE AND COST RECOGNITION
 
     The Company recognizes revenues from fixed-fee contracts using the
percentage-of-completion method, measured by the percentage of cost incurred to
date to management's estimated total cost for each contract. That method is used
because management considers total cost to be the best available measure of
progress on the contracts. Changes in job performance, job conditions and
estimated profitability may result in revisions to cost and income, which are
recognized in the period in which the revisions are determined.
 
     Revenues from time-and-material contracts are recognized currently as the
work is performed.
 
     Contract costs include all direct material, labor and equipment costs
related to contract performance. General and administrative costs are charged to
expense as incurred. Provisions for estimated losses on uncompleted contracts
are made in the period in which such losses are determined.
 
     The asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts", represents revenues recognized in excess of amounts
billed. The liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts", represents billings in excess of revenues recognized.
 
INCOME TAXES
 
     The Company operates as an S Corporation. Accordingly, the income taxes
related to the earnings of the Company are the responsibility of the owners;
therefore, these combined financial statements do not reflect any federal or
state income taxes for the Company.
 
SINGLE BUSINESS TAX
 
     The Company is subject to a single business tax in its incorporated state
of Michigan. The tax is calculated on the apportioned activity of the Company in
Michigan and is included in general and administrative expenses in the
accompanying combined statements of income.
 
USE OF ESTIMATES
 
     Management uses estimates and assumptions in preparing financial
statements. Those estimates and assumptions affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities, and
the reported revenues and expenses. Actual results could vary from the estimates
that were assumed in preparing the financial statements.
 
INTERIM FINANCIAL STATEMENTS
 
     The unaudited financial statements included herein have been prepared,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission ("SEC"). In the opinion of management, the accompanying
unaudited financial statements reflect all adjustments necessary to present
fairly the financial position as of March 31, 1998 and the results of operations
and cash flows for the three months ended March 31, 1997 and 1998.

Value of Financial Instruments." The estimated fair value amounts have been
determined by the Company using available market information and appropriate
valuation methodologies.
 
  Cash, accounts receivable and accounts payable
 
     The carrying amounts of these items are a reasonable estimate of their fair
value due to their short-term nature.
 
  Line of credit and long-term debt
 
     The carrying amount of the line of credit facility approximates fair value
as the interest rate fluctuates with changes in market conditions. The carrying
amount of long-term debt, based on borrowing rates currently available to the
Company, is a reasonable estimation of fair value.
 
11. SUBSEQUENT EVENT (UNAUDITED)

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 102(b)(7) of the Delaware General Corporation Law (the "DGCL")
permits a corporation, in its certificate of incorporation, to limit or
eliminate, subject to certain statutory limitations, the liability of directors
to the corporation or its stockholders for monetary damages for breaches of
fiduciary duty, except for liability (a) for any breach of the director's duty
of loyalty to the corporation or its stockholders, (b) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (c) under Section 174 of the DGCL, or (d) for any transaction from which
the director derived an improper personal benefit. Article 10 of the
registrant's restated Certificate of Incorporation provides that the personal
liability of directors of the registrant is eliminated to the fullest extent
permitted by Section 102(b)(7) of the DGCL.
 
     Under Section 145 of the DGCL, a corporation has the power to indemnify
directors and officers under certain prescribed circumstances and subject to
certain limitations against certain costs and expenses, including attorneys'
fees actually and reasonably incurred in connection with any action, suit or
proceeding, whether civil, criminal, administrative or investigative, to which
any of them is a party by reason of being a director or officer of the
corporation if it is determined that the director or officer acted in accordance
with the applicable standard of conduct set forth in such statutory provision.
Article 7 of the registrant's Bylaws provides that the registrant will indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding by reason of the
fact that he is or was a director, officer, employee or agent of the registrant,
or is or was serving at the request of the registrant as a director, officer,
employee or agent of another entity, against certain liabilities, costs and
expenses. Article 7 further permits the registrant to maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
registrant, or is or was serving at the request of the registrant as a director,
officer, employee or agent of another entity, against any liability asserted
against such person and incurred by such person in any such capacity or arising
out of his status as such, whether or not the registrant would have the power to
indemnify such person against such liability under the DGCL. The registrant
expects to maintain directors' and officers' liability insurance.
 
     Under the Underwriting Agreement, the Underwriters are obligated, under
certain circumstances, to indemnify directors and officers of the registrant
against certain liabilities, including liabilities under the Securities Act of
1933, as amended (the "Securities Act"). Reference is made to the form of
Underwriting Agreement filed as Exhibit 1.1 hereto.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreements, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer, or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer, or controlling person
in connection with the securities being registered hereunder, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
     The Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to
 
                                      II-4
<PAGE>   228
 
     Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to
     be part of this Registration Statement as of the time it was declared
     effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

                        SIGNATURES AND POWER OF ATTORNEY
 
   
     Pursuant to the requirements of the Securities Act of 1933, the Registrant
has duly caused this Amendment to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Atlanta, State of Georgia, on July 29,
