                                  The Offering

Trust...................  The GATX Rail Corporation 2000-1 Pass Through Trust
                          will be formed pursuant to a pass through trust
                          supplement to be entered into pursuant to the Pass
                          Through Trust Agreement between GATX Rail Corporation
                          and Bank One, NA (formerly The First National Bank of
                          Chicago), as trustee under the Trust.

Certificates Offered....  Series 2000-1. The Certificates will represent a
                          fractional undivided interest in the Trust.

Trust Property..........  The property of the Trust will consist of equipment
                          notes issued on a nonrecourse basis by two owner
                          trusts pursuant to two separate leveraged lease
                          transactions. The equipment notes will finance not
                          more than 80% of the purchase price of certain
                          railroad tank cars and covered hopper cars which are
                          to be purchased from GATX Rail Corporation, and
                          thereafter, leased back to GATX Rail Corporation. The
                          railcars to be purchased by an owner trust are
                          referred to as an "equipment group" and all of the
                          railcars being purchased in the transactions are
                          referred to collectively as the "equipment." The
                          composition of the equipment groups, each divided
                          into four subgroups by type of railcar, is described
                          in "Use of Proceeds" in this prospectus supplement.
                          Each subgroup is referred to as a "Basic Group."

                          Four equipment notes will be issued with respect to
                          each leveraged lease transaction, one with respect to
                          each Basic Group of equipment. The equipment notes
                          acquired by the Trust will bear interest at the same
                          rate as the rate of the Certificates issued by the
                          Trust. The final maturity date of the equipment notes
                          to be acquired by the Trust will occur on or before
                          the final distribution date of the Certificates. The
                          aggregate principal amount of the equipment notes to
                          be held in the Trust will be the same as the
                          aggregate principal amount of the Certificates.

Book-Entry                The Certificates will be issued in fully registered
Registration............  form and will be registered in the name of Cede & Co.
                          as the nominee of The Depository Trust Company
                          ("DTC"). The investment interests of investors will
                          be recorded through the book-entry registration
                          maintained by DTC.

                          on the equipment notes being prepaid will be
                          distributed on a Special Distribution Date after not

Same-Day Settlement.....  The Certificates will trade in DTC's Same Day Funds
                          Settlement System until maturity. Therefore,
                          purchases and sales of Certificates in the secondary
                          market must settle in immediately available funds.

Method of                 So long as the Certificates are registered in the
Distributions...........  name of Cede & Co., as nominee of DTC, distributions
                          by the Trustee will be made in same-day funds to DTC,
                          which will in turn make distributions to participants
                          in DTC in same-day funds. DTC participants will be
                          responsible for distributions to beneficial owners of
                          the Certificates.

Interest................  Certificateholders are entitled to receive interest
                          on the Certificates at the rate per annum indicated
                          on the cover of this prospectus supplement. This is
                          the same interest rate borne by the equipment notes
                          to be held in the Trust issuing such Certificates.
                          Interest is calculated on the basis of a 360-day year
                          of twelve 30-day months.

                          Payments of interest on each of the equipment notes
                          held in the Trust are scheduled to be received by the
                          Trustee on January 13 and July 13 of each year,
                          commencing July 13, 2000, and are to be distributed
                          to the Certificateholders on the corresponding
                          Regular Distribution Date.

Principal...............  Payments of principal on the equipment notes are
                          scheduled to be received in specified amounts by the
                          Trustee on January 13 or July 13, or both, of each
                          year, commencing July 13, 2002, and are to be
                          distributed to the Certificateholders on the
                          corresponding Regular Distribution Dates.

                          The principal repayment schedule for the equipment
                          notes is set forth under "Description of the
                          Equipment Notes--Principal Payments."

Equipment Notes:          All or a portion of the equipment notes may be
Prepayment..............  prepaid under the following circumstances:

                          (a) Upon the occurrence of an Event of Loss with
                              respect to one or more railcars, if the railcars
                              are not replaced, all or a portion, as the case
                              may be, of the equipment notes issued with
                              respect to the equipment group in which such
                              railcars were included are subject to prepayment
                              on a Regular Distribution Date. If prepayment is
                              required due to Events of Loss as to 15 or more
                              railcars within an equipment group, then the
                              related equipment notes are subject to prepayment
                              on a Special Distribution Date if earlier than
                              the next Regular Distribution Date. The required
                              prepayment price will be an amount equal to the
                              sum of:

                            (1) an amount of principal equal to the unpaid
                                principal amount (as of such prepayment date)
                                of the equipment notes issued with respect to
                                the Basic Group in which the related railcars
                                were included (after deducting the principal
                                installment, if any, due on such date)
                                multiplied by a fraction, the numerator of
                                which shall be the cost of the related
                                railcars and the denominator of which shall be
                                the aggregate cost of all railcars in such
                                Basic Group immediately prior to such
                                prepayment date; and

<PAGE>


                            (2) the aggregate amount of interest accrued and
                                unpaid in respect of the principal amount to
                                be prepaid pursuant to paragraph (1) above on
                                such prepayment date (after giving effect to
                                the application of any principal paid on or
                                prior to the date of such prepayment), but
                                without the payment of any premium.

                          (b) GATX Rail Corporation has the right to purchase
                              railcars from either of the owner trusts at any
                              time if the related owner participant or any of
                              its affiliates engages in a business that is in
                              competition with GATX Rail Corporation's full
                              service railcar leasing business. If GATX Rail
                              Corporation elects to exercise this right, all of
                              the equipment notes issued by the applicable
                              Owner Trustee are required to be prepaid on a
                              Special Distribution Date. In the alternative,
                              GATX Rail Corporation may elect to assume the
                              related equipment notes on a full recourse basis.
                              If prepaid, the required prepayment price is the
                              unpaid principal amount, computed as provided in
                              paragraph (a) above, together with accrued
                              interest thereon to the date of prepayment,
                              computed as provided in paragraph (a) above plus
                              the applicable premium. See "Description of the
                              Equipment Notes--Prepayments" for a description
                              of the manner of computing the applicable
                              premium.

                          (c) In the event of a refinancing of the equipment
                              notes issued with respect to any equipment group,
                              all of the equipment notes issued by the
                              applicable Owner Trustee will be prepaid on the
                              date of such refinancing, which may be any
                              business day, and the prepayment price shall be
                              equal to the unpaid principal amount of such
                              equipment notes, together with accrued interest
                              thereon, plus the applicable premium referred to
                              in paragraph (b) above.

                          (d) At any time on or after April 13, 2007, GATX Rail
                              Corporation has the right to terminate the Lease
                              with respect to all or some of the railcars
                              within any Basic Group, in which case it would be
                              required to prepay the related equipment notes.
                              It also has certain rights to purchase all or
                              some of the railcars within any Basic Group on
                              different specified dates on or after July 13,
                              2010. If GATX Rail Corporation elects to exercise
                              any of these purchase rights, it can either
                              assume the related equipment notes on a full
                              recourse basis or prepay the equipment notes
                              related to the affected railcars. If the related
                              equipment notes are to be prepaid, the amounts
                              due will equal the prepayment price computed as
                              provided in paragraph (a) above, plus the
                              applicable premium referred to in paragraph (b)
                              above, and will be payable on a Regular
                              Distribution Date (or, in certain limited
                              circumstances, a Special Distribution Date).

                          (e) Each Owner Trustee may elect to purchase all of
                              the then outstanding equipment notes issued by
                              the related owner trust at a price equal to the
                              aggregate unpaid principal amount, together with
                              accrued interest, but without the payment of any
                              premium, if under the applicable Indenture:

                            (1) the payment date of such equipment notes has
                                been accelerated;

<PAGE>


                            (2) the applicable Indenture Trustee, as assignee
                                of the related Lease, declares the Lease to be
                                in default and begins to exercise any
                                additional remedy in respect of the equipment
                                under such Lease; or

                            (3) one or more Lease Events of Default under the
                                related Lease occurs and continues for 180
                                days or more during which time the equipment
                                notes issued under such Indenture could have
                                been accelerated. See "Description of the
                                Equipment Notes--Prepayments."

Equipment Notes:          The equipment notes issued under each Indenture will
Security................  be secured by a security interest in the
                          corresponding equipment group leased by GATX Rail
                          Corporation under the Lease with the related Owner
                          Trustee and by an assignment to the Indenture Trustee
                          of certain of the Owner Trustee's rights under the
                          Lease covering such equipment, including the right to
                          receive rentals payable by GATX Rail Corporation in
                          respect of the related equipment.

                          The equipment notes issued under one Indenture will
                          not be secured by any of the equipment securing the
                          other Indenture or by the Lease relating to the other
                          equipment group. There are no cross-default
                          provisions in the Indentures and events resulting in
                          a default under an Indenture, or a default under any
                          other indebtedness of GATX Rail Corporation, will not
                          necessarily result in a default under the other
                          Indenture.

                          In the event of the bankruptcy of an owner
                          participant, it is possible that, notwithstanding
                          that the related equipment group is owned by an Owner
                          Trustee in trust, such equipment group and the
                          related Lease and equipment notes might become part
                          of the bankruptcy proceeding. Such an event could
                          cause payments on the related equipment notes to be
                          interrupted and the ability of the Indenture Trustee
                          to exercise its remedies under the applicable
                          Indenture might be restricted. However, the Indenture
                          Trustee would retain its status as a secured creditor
                          relating to such Lease and equipment group. See
                          "Description of the Equipment Notes--Indenture Events
                          of Default and Remedies" in the accompanying
                          prospectus.

                          If a default occurs under an Indenture and is not
                          cured, the Trustee will be entitled to control the
                          exercise of certain remedies under that Indenture or
                          to sell all or part of the equipment notes issued
                          under such Indenture. If the institution acting as
                          Trustee is acting as trustee of other pass through
                          trusts formed pursuant to the Basic Agreement and
                          there are also defaults under such trusts, the
                          Trustee may have a conflict of interest in deciding
                          from which trust to sell equipment notes to any
                          available buyers. If the Trustee sells any of the
                          equipment notes held by the Trust for less than their
                          outstanding principal amount, the Certificateholders
                          will receive a smaller principal distribution than
                          anticipated and will not have any claim for the
                          shortfall against GATX Rail Corporation, the related
                          Owner Trustee, the related owner participant or the
                          Trustee. See "Description of the Pass Through
                          Certificates--Events of Default and

                          accompanying prospectus.

                          Although the equipment notes are not direct
                          obligations of, or guaranteed by, GATX Rail
                          Corporation, the amounts unconditionally payable by
                          GATX Rail Corporation under the Leases will be
                          sufficient to pay in full all scheduled payments of
                          principal of, and interest on, the equipment notes
                          when due.

Use of Proceeds.........
                          All of the proceeds from the sale of the Certificates
                          will be used to purchase the equipment notes, at par,
                          being issued concurrently by two owner trusts to
                          finance a portion of their acquisition of the
                          railcars from GATX Rail Corporation. The net proceeds
                          to GATX Rail Corporation from the sale of the
                          railcars will be used by GATX Rail Corporation to
                          repay outstanding indebtedness.

Trustee; Paying Agent
and Registrar...........  Bank One, NA (formerly The First National Bank of
                          Chicago) will act as Trustee, and as paying agent and
                          registrar, for the Certificates. Bank One, NA
                          (formerly The First National Bank of Chicago) will
                          also act as the Indenture Trustee under each
                          Indenture.

Certain U.S. Federal
Income Tax                The Trust will be classified as a grantor trust for
Consequences............  federal income tax purposes. Each beneficial owner of
                          a Certificate generally will be required to report on
                          its federal income tax return its pro rata share of
                          income from such equipment notes and such other
                          property held in the Trust in accordance with such
                          Certificateholder's method of accounting.

ERISA Considerations....  The Certificates, with certain exceptions, are
                          eligible for purchase by employee benefit plans. See
                          "ERISA Considerations" in this prospectus supplement
                          and in the accompanying prospectus.

                              DIAGRAM OF PAYMENTS

   The following diagram shows the structure resulting from the sale-leaseback
transactions and illustrates certain aspects of the payment flows.

   In each of the two separate transactions, GATX Rail Corporation will sell a
specified group of railcars to an owner trust and then lease the railcars back
under a Lease with the Owner Trustee. Each owner trust will issue equipment
notes under an Indenture, and the Trustee will purchase all of the equipment
notes from the two owner trusts for the benefit of the Certificateholders. Rent
is payable by GATX Rail Corporation to each Owner Trustee under the
corresponding Lease. However, as a result of the assignment of certain rights
of each Owner Trustee under the related Lease to the related Indenture Trustee,
GATX Rail Corporation will make rental payments directly to each Indenture
Trustee. From these rental payments, each Indenture Trustee will, on behalf of
the related Owner Trustee, first make payments to the Trustee on the equipment
notes and then pay the remaining balance to such Owner Trustee, for the benefit
of the applicable owner participant. The Trustee will distribute payments
received to the Certificateholders. Bank One, NA (formerly The First National
Bank of Chicago) will act initially both as Trustee of the Trust and as
Indenture Trustee under each Indenture.

                                USE OF PROCEEDS

   All of the proceeds from the sale of the Certificates will be used by the
Trust to purchase equipment notes that will provide debt financing for the two
sale-leaseback transactions. In the transactions, equipment notes will be
issued by two separate owner trusts that are purchasing specific groups of
railcars--the equipment groups--from GATX Rail Corporation and then leasing the
railcars back to GATX Rail Corporation. GATX Rail Corporation will use the net
proceeds from the sale of the railcars, after deducting expenses of this
offering and underwriting commissions, to repay outstanding indebtedness.

   The aggregate principal amount of the equipment notes to be held in the
Trust will be the same as the aggregate principal amount of the Certificates.
The equipment notes acquired by the Trust will bear interest at the same rate
as the Certificates. In addition to the debt funding, the owner participant for
each owner trust will provide equity funding in an amount equal to at least 20%
of the equipment cost of the equipment group being acquired by that owner
trust.

   The following table provides information about the two equipment groups
expected to be purchased by the owner trusts. In total, there are an aggregate
of 2,718 railcars comprising the equipment. All of the railcars were
manufactured in 1996, 1997 or 1998.

   GATX Rail Corporation has entered into a $350.0 million revolving credit
facility which expires in 2003. Borrowings under this credit facility will be
unsecured. The full amount of the facility can be used for general corporate
purposes. No borrowings were outstanding under the facility at December 31,
1999. However, because GATX Rail Corporation had $132.6 million of commercial
paper outstanding at December 31, 1999, the line of credit remaining available
under the facility was reduced by the same amount. As of December 31, 1999,
GATX Rail Corporation also had borrowings of $115.0 million under unsecured
money market lines.

    amortization of debt discount and expenses. "Earnings" consist of
    consolidated net income before income taxes and fixed charges, less share
    of affiliates' earnings, net of distributions received.

(B) In 1997, net loss included restructuring charges of $123.8 million.
    Excluding the charges, the "ratio of earnings to fixed charges" was 1.34x.

GATX Rail/Railcar Leasing and Management Business Segment

   The discussion below relates to the company's GATX Rail/railcar leasing and
management segment. GATX Rail leases specialized railcars, primarily tank cars,
under full service leases. As of December 31, 1999, its total North American
fleet consisted of approximately 87,800 railcars, comprised of 67,900 tank cars
and 19,900 specialized freight cars, including conventional and Airslide(TM)
covered hopper cars. In addition to 76,000 railcars in the United States, as of
December 31, 1999, GATX Rail had 9,200 railcars in its Canadian fleet and 2,600
railcars in its Mexican fleet. The utilization rate of GATX Rail's North
American railcar fleet as of December 31, 1999 was approximately 95%. GATX
Rail's railcars have a useful life of 20 to 33 years. As of December 31, 1999,
the average age of the railcars was approximately 16 years.

   In addition to the North American fleet, GATX Rail has ownership interests
in two European fleets through investments in affiliated companies. GATX Rail
owns a 46% interest in KVG Kesselwagen Vermietgesellschaft mbH, a German and
Austrian-based tank car and specialty railcar leasing company, and an 18.8%
interest in AAE Cargo, headquartered in Switzerland.

   Included in the total North American fleet numbers shown above are fleets of
railcars leased by General American Railcar Corporation, General American
Railcar Corporation II, and General American Railcar Corporation III, separate
wholly owned special purpose subsidiaries of GATX Rail formed in 1997, 1998 and
1999, respectively, which GATX Rail manages. According to the terms of the
management agreements with these entities, GATX Rail, as manager, is prohibited
from discriminating between the railcars owned by these entities and any other
railcars in its fleet, whether owned or managed, on the basis of ownership or
any other potentially discriminating basis. In the future, GATX Rail may manage
the leasing of fleets of railcars owned or leased by other affiliates as well.

   GATX Rail leases railcars to over 700 customers, including major chemical,
oil, food and agricultural companies. Customers use the railcars to ship over
700 different commodities, primarily chemicals, petroleum, and food products.
For 1999, approximately 47% of railcar leasing revenue was attributable to
shipments of chemical products, 31% to food and other products, and 22% to
petroleum products. No single customer accounts for more than 3% of total
railcar leasing revenue.

   GATX Rail typically leases new railcars to its customers for a term of five
years or longer, whereas renewals of leases of existing railcars are typically
for periods ranging from less than a year to seven years, with an average lease
term of about three years. GATX Rail purchases most of its new railcars from
Trinity Industries, Inc., a Dallas-based metal products manufacturer.

   Under its full service leases, GATX Rail maintains and services its
railcars, pays ad valorem taxes, and provides many ancillary services. Through
its Internet website, GATX Rail provides customers with timely analysis,
performance statistics, and mechanical record information to enhance and
maximize the utilization of their leased railcars. GATX Rail also maintains a
network of major service centers consisting of four domestic, four Canadian and
one Mexican facility. To supplement the nine major service centers, GATX Rail
utilizes a fleet of mobile trucks and also utilizes independent third-party
repair shops.

   The full-service railcar leasing industry is comprised of GATX Rail
Corporation, Union Tank Car Company, General Electric Railcar Services
Corporation, and many smaller companies. As of the end of 1999, GATX Rail
managed 23% of the 266,000 tank cars owned and leased in the United States.
Principal competitive factors include price, service and availability.

   Because GATX Rail's obligation under the Leases to make payments sufficient
to pay in full the equipment notes will be unconditional, and its obligations
are not affected by the financial performance of any of the railcars covered by
the Leases, no historical, financial or operating information is being
furnished about the specific equipment groups covered by the Leases.

Terminals and Pipelines Business Segment

   The discussion below relates to the terminals and pipelines segment of the
company's business. This business is conducted by GATX Terminals Corporation,
which is engaged in the storage, handling and transfer of petroleum and
chemical commodities at key points in the bulk liquid distribution chain. Its
terminals and pipelines facilities are located near major transportation points
and are capable of receiving and shipping bulk liquids by ship, rail, barge and
truck. Many of the terminals are also linked with major interstate pipelines.
In addition to storing, handling and transferring bulk liquids, the company
provides blending and testing services at most of its facilities. GATX
Terminals Corporation, headquartered in Chicago, Illinois, owns and operates 15
terminals in the United States and also has interests in European, Asian and
Mexican facilities. In addition to storage facilities, GATX Terminals owns or
holds interests in four refined products pipeline systems.

   For 1999, 49% of the terminals and pipelines revenue was derived from
petroleum storage, 24% from chemical storage and 27% from pipelines. Demand for
these facilities depends in part upon demand for petroleum and chemical
products and is also affected by refinery output, foreign imports, availability
of other storage facilities, and the expansion of its customers into new
geographical markets.

   GATX Terminals serves over 500 customers, including major oil and chemical
companies as well as trading firms and larger independent refiners. No single
customer accounted for more than 8% of this segment's gross income.

   Within the worldwide public petroleum and chemical terminalling industry,
Koninkliijke Vopak ("Vopak") is the company's principal competitor. Vopak is
the largest in terms of capacity, followed by GATX Terminals Corporation. Vopak
was formed in 1999 through the merger of two Dutch companies, PAKHOED N.V. and
Van Ommeren N.V. GATX Terminals also competes with smaller terminalling
companies as well as oil and chemical companies that have significant storage
capacity in a number of markets. In the pipeline business, GATX Terminals
competes with rail, trucks, and other pipelines in the movement of liquid
petroleum products. In early 2000, GATX Terminals Corporation purchased Vopak's
ownership interests in Gamatex N.V. located in Belgium, and in Tankstore Ltd.,
located in Singapore. As a result, GATX Terminals Corporation now owns 100% of
both Gamatex N.V. and Tankstore Ltd. In turn, GATX Terminals Corporation sold
to Vopak its 50% ownership interest in Tees Storage Company Ltd., a terminal
facility in Middlesborough, England.

Relationship with GATX Corporation

   All of GATX Rail Corporation's outstanding common stock is owned by GATX
Corporation. GATX Corporation will not guarantee the Certificates and does not
guarantee any other indebtedness of GATX Rail Corporation. GATX Rail
Corporation, in the normal course of business, declares dividends to GATX
Corporation to provide for GATX Corporation's normal operating expenses.
Additional amounts have been advanced to GATX Corporation from time to time for
corporate purposes, the redemption of GATX Corporation preferred stock and the
retirement of debt. In addition, GATX Corporation may make advances to
subsidiaries of GATX Rail Corporation in the normal course of business.
Interest income on advances by GATX Rail Corporation to GATX Corporation was
$26.4 million in 1999, $27.2 million in 1998 and $28.9 million in 1997.

   GATX Rail Corporation and its subsidiaries contribute to GATX Corporation
pension plans which cover substantially all of GATX Rail Corporation's
employees. Costs are allocated to GATX Rail Corporation on the basis of payroll
costs with respect to normal cost and on the basis of actuarial determinations
for prior service cost. In addition to pension benefits, GATX Rail
Corporation's employees participate in life insurance and dental and medical
programs sponsored by GATX Corporation.

   GATX Rail Corporation and GATX Corporation have policies allocating income
tax liabilities. These policies provide generally for the filing of
consolidated tax returns by GATX Corporation, but with payments to or from GATX
Rail Corporation as though it had filed a separate return, except that GATX
Rail Corporation might not benefit from its investment tax credits and foreign
taxes paid to the same extent as if separate returns had been filed.

Legal Proceedings

   GATX Rail Corporation and its subsidiaries have been named as defendants in
a number of pending lawsuits.

   GATX Rail Corporation and GATX Terminals Corporation are two of the nine
defendants named in In re New Orleans Tank Car Leakage Fire Litigation, Civil
Action No. 87-16374, Civil District Court for the Parish of Orleans, State of
Louisiana. The litigation arises from the September 1987 leak of butadiene from
a tank car owned by GATX Rail Corporation and the subsequent fire. The
butadiene was loaded into the tank car at a facility owned and operated by GATX
Terminals Corporation. Discovery taken to date has shown the leak and fire did
not cause any deaths or serious personal injuries, but did result in an
approximate 36-hour evacuation of persons in the affected area.

   The tank car litigation was certified as a class action in 1993. A trial of
the compensatory damage claim of 20 selected plaintiffs and of the punitive
damage claims of the class was conducted in 1997. In September 1997, the jury
awarded approximately $1.9 million plus interest as compensatory damages to the
20 plaintiffs and $3.4 billion as punitive damages in favor of the class,
including $190 million against GATX Terminals Corporation. GATX Rail
Corporation is not liable for punitive damages. In July 1999, the court
conducted a trial on the compensatory claims of an additional twenty
plaintiffs; the jury awarded a total of $344,300 in compensatory damages.

   In October 1999, GATX Rail Corporation, GATX Terminals Corporation, three
other defendants and the Plaintiffs' Management Committee acting on behalf of
the class executed a preliminary settlement agreement. The agreement provides
for the release of any and all claims against the five defendants, including
GATX Rail Corporation and GATX Terminals Corporation, arising out of the tank
car incident, including all of the claims asserted by the class, as
consideration for the payment of a negotiated cash amount. A sixth defendant
has entered into a separate settlement agreement with the class. In November
1999, the court gave preliminary approval to the settlement and directed that
notice of the proposed settlement be given to all class members and other
interested persons. The court also ordered that a final hearing on the fairness
of the settlement be conducted on March 22, 2000.

   At the conclusion of the March 22 fairness hearing, the court found that the
settlement is fair, reasonable and adequate and complies with all of the
constitutional and statutory requirements. Based upon that finding, the court
entered a judgment which dismisses the litigation with prejudice as to GATX
Rail Corporation, GATX Terminals Corporation and the other settling defendants,
releases them from any and all claims arising out of or relating to the tank
car incident, including all claims of the class and class members for
compensatory damages, and requires that the class and class members indemnify
GATX Rail Corporation, GATX Terminals Corporation and the other settling
defendants with respect to all such claims. The dismissal and the release and
indemnity shall become effective upon the judgment becoming final and no longer
subject to appeal or writ of certiorari. As there were no objections presented
to the settlement, GATX Rail Corporation believes that the prospect that an
appeal will result in the reversal of the judgment is extremely remote.

   GATX Rail Corporation and its subsidiaries are engaged in various matters of
litigation including but not limited to those matters described above, and have
a number of unresolved claims pending, including proceedings under governmental
laws and regulations related to environmental matters. While the amounts
claimed are substantial and the ultimate liability with respect to such
litigation and claims cannot be determined at this time, it is the opinion of
management that damages, if any, required to be paid by GATX Rail Corporation
and its subsidiaries in the discharge of such liability are not likely to be
material to GATX Rail Corporation's consolidated results of operations or
financial position.

Environmental Matters

   Certain operations of GATX Rail Corporation and its subsidiaries present
potential environmental risks principally through the transportation or storage
of various commodities. Recognizing that some risk to the

                                      S-16
<PAGE>

environment is intrinsic to its operations, GATX Rail Corporation is committed
to protecting the environment, as well as complying with applicable
environmental protection laws and regulations. GATX Rail Corporation, as well
as its competitors, is subject to extensive regulation under federal, state and
local environmental laws which have the effect of increasing the costs and
liabilities associated with the conduct of its operations. In addition, GATX
Rail Corporation's foreign operations are subject to environmental laws in
effect in each respective jurisdiction.

   GATX Rail Corporation's policy is to monitor and actively address
environmental concerns in a responsible manner. GATX Rail Corporation has
received notices from the U.S. Environmental Protection Agency ("EPA") that it
is a potentially responsible party ("PRP") for study and clean-up costs at 13
sites under the requirements of the Federal Comprehensive Environmental
Response, Compensation and Liability Act of 1980. Under these Acts and
comparable state laws, GATX Rail Corporation may be required to share in the
cost to clean-up various contaminated sites identified by the EPA and other
agencies. The company has also received notice that it is a PRP at one site to
undertake a Natural Resource Damage Assessment. In all instances, GATX Rail
Corporation is one of a number of financially responsible PRPs and has been
identified as contributing only a small percentage of the contamination at each
of the sites. Due to various factors such as the required level of remediation
or restoration and participation in clean-up or restoration efforts by others,
GATX Rail Corporation's total clean-up costs at these sites cannot be predicted
with certainty; however, GATX Rail Corporation's best estimates for remediation
and restoration of these sites have been determined and are included in its
environmental reserves.

   Future costs of environmental compliance cannot be determined due to
unknowns such as the magnitude of possible contamination, the timing and extent
of the corrective actions that may be required, the determination of the
company's liability in proportion to other responsible parties, and the extent
to which such costs are recoverable from third parties including insurers.
Also, GATX Rail Corporation may incur additional costs relating to facilities
and sites where past operations followed practices and procedures that were
considered acceptable at the time but in the future may require investigation
and/or remedial work to ensure adequate protection to the environment under
current or future standards. If future laws and regulations contain more
stringent requirements than presently anticipated, expenditures may be higher
than the estimates, forecasts, and assessments of potential environmental costs
provided below. However, these costs are expected to be at least equal to the
current level of expenditures. In addition, GATX Rail Corporation has provided
indemnities for environmental issues to the buyers of two divested companies
and a number of divested terminals facilities for which the company believes it
has adequate reserves.

   GATX Rail Corporation's environmental reserve at the end of 1999 was $72
million and reflects the company's best estimate of the cost to remediate known
environmental conditions. Additions to the reserve were $12 million in both
1999 and 1998. Expenditures charged to the reserve amounted to $8 million and
$9 million in 1999 and 1998, respectively.

   In 1999, GATX Rail Corporation made capital expenditures of $8 million for
environmental and regulatory compliance compared to $5 million in 1998. These
projects included marine vapor recovery, discharge prevention compliance, waste
water systems, impervious dikes, tank modifications for emissions control, and
tank car cleaning systems. Environmental projects authorized or planned would
require capital expenditures of approximately $11 million in 2000. GATX Rail
Corporation anticipates it will make annual expenditures at approximately the
same level over the next three years.

                      FORMATION OF THE PASS THROUGH TRUST

   The Trust will be formed pursuant to a trust supplement between the Trustee
and GATX Rail Corporation in accordance with the terms of the Pass Through
Trust Agreement, dated as of August 1, 1992 between GATX Rail Corporation and
The First National Bank of Chicago (predecessor to Bank One, NA) (the "Basic
Agreement"). All Certificates issued with respect to the Trust will represent
fractional undivided interests in the Trust and the property held in the Trust,
and will have no rights, benefits or interest in respect of any other

                                      S-17
<PAGE>

trust or the property held therein. Concurrently with the execution and
delivery of the trust supplement, the Trustee, on behalf of the Trust, will
enter into a Participation Agreement with respect to each of the two leveraged
lease transactions. Pursuant to the Participation Agreements, the Trustee, on
behalf of the Trust, will purchase all of the equipment notes issued by the
owner trusts. The equipment notes held in the Trust will have an interest rate
equal to the interest rate applicable to the Certificates issued by the Trust.
The maturity dates of the equipment notes will occur on or before the final
distribution date of the Certificates. The Trustee will distribute the payments
of principal, premium and interest received by it as holder of the equipment
notes to the Certificateholders. See "Description of the Certificates" and
"Description of the Equipment Notes."

                        DESCRIPTION OF THE CERTIFICATES

   The Certificates will be issued pursuant to a trust supplement, to be
entered into between GATX Rail Corporation and the Trustee pursuant to the
Basic Agreement. The following summary of the particular terms of the
Certificates supplements, and to the extent inconsistent therewith replaces,
the description of the general terms and provisions of the Certificates set
forth in the accompanying prospectus under the heading "Description of the Pass
Through Certificates." The summary makes use of terms defined in and is
qualified in its entirety by reference to all of the provisions of the Basic
Agreement, a copy of which has been filed as an exhibit to the Registration
Statement of which the prospectus is a part, and to all the provisions of the
trust supplement which, together with the forms of the related equipment notes,
Indentures, Leases, Trust Agreements and Participation Agreements, will be
filed as exhibits to a Current Report on Form 8-K to be filed by GATX Rail
Corporation with the Securities and Exchange Commission.

General

   Each Certificate will represent a fractional undivided interest in the
Trust. The property of the Trust will consist of the equipment notes to be
issued on a nonrecourse basis by each of the owner trusts in connection with
two separate leveraged lease transactions. The equipment notes will finance not
more than 80% of the cost to each of the Owner Trustees to purchase a specified
equipment group from GATX Rail Corporation and then lease the equipment group
back to GATX Rail Corporation. See "Use of Proceeds."

   Four equipment notes will be issued by each owner trust. All of the
equipment notes will have an interest rate equal to the interest rate of the
Certificates and will mature on or before the final distribution date of the
Certificates. The aggregate principal amount of the equipment notes held in the
Trust will be the same as the aggregate principal amount of the Certificates.
For a description of the equipment notes and the Indentures, see "Description
of the Equipment Notes" in this prospectus supplement and the accompanying
prospectus.

Payments and Distributions

   Payments of interest on the equipment notes are scheduled to be received by
the Trustee on January 13 and July 13 of each year, commencing July 13, 2000,
until the final distribution date for the Trust. Payments of principal on the
equipment notes are scheduled to be received in specified amounts by the
Trustee on January 13 or July 13, or both, of each year commencing July 13,
2002. January 13 and July 13 of each year are referred to in this prospectus
supplement as "Regular Distribution Dates."

   The following Special Payments, if any, will also be distributed on the next
Regular Distribution Date or, in certain circumstances if sooner, the 13th day
of a month (a "Special Distribution Date"):

  (1) payments of principal, premium and interest received by the Trustee on
      account of a partial or full prepayment of the equipment notes; and

  (2) payments received by the Trustee following a default in any equipment
      notes, including payments received by the Trustee on account of a
      purchase by the related Owner Trustee of such equipment notes or
      payments received on account of the sale of such equipment notes by the
      Trustee.

                                      S-18
<PAGE>

In the case of a refinancing of equipment notes, payments of principal, premium
and interest will be distributed on the date of such refinancing, which may
occur on any business day. The Trustee is required to provide not less than 20
days' notice of Special Payments or refinancing to the holders of the
Certificates. See "Description of the Pass Through Certificates--Payments and
Distributions" in the accompanying prospectus, "Description of the Equipment
Notes--Prepayments" in this prospectus supplement and "Description of the

                       DESCRIPTION OF THE EQUIPMENT NOTES

   The following summary of the particular terms and provisions of the
equipment notes supplements, and to the extent inconsistent therewith replaces,
the description of the general terms and provisions of the equipment notes set
forth in the accompanying prospectus under the heading "Description of the
Equipment Notes." The summaries make use of terms defined in and are qualified
in their entirety by reference to all of the provisions of the equipment notes,
the Indentures, the Leases, the Participation Agreements and the Trust
Agreements, the forms of which will be filed as exhibits to a Current Report on
Form 8-K to be filed by GATX Rail Corporation with the SEC. Except as otherwise
indicated, the following summaries relate to the equipment notes, the
Indenture, the Lease, the Participation Agreement and the Trust Agreement
relating to each equipment group.

General

   Four equipment notes will be issued with respect to each of the two
leveraged lease transactions. For each leveraged lease transaction there will
be a separate Trust Indenture and Security Agreement (each an "Indenture")
between Wilmington Trust Company, as Owner Trustee of a trust for the benefit
of the owner participant who is the beneficial owner of such equipment group,
and Bank One, NA (formerly The First National Bank of Chicago), as Indenture
Trustee.

   The related Owner Trustee will lease each equipment group to GATX Rail
Corporation pursuant to a separate Lease between such Owner Trustee and GATX
Rail Corporation. GATX Rail Corporation is obligated to make or cause to be
made rental and other payments to each Indenture Trustee on behalf of the
related Owner Trustee in amounts that will be at least sufficient to pay the
principal of, premium and interest on the equipment notes issued with respect
to such equipment group when and as due and payable. Any excess over the amount
of scheduled principal, premium and interest will be paid to the related Owner
Trustee.

   GATX Rail Corporation's rental obligations under the Leases are general
obligations of GATX Rail Corporation. The equipment notes are not, however,
direct obligations of, or guaranteed by, GATX Rail Corporation or any affiliate
thereof.

Interest Payments

   Interest will be payable on the unpaid principal amount of each equipment
note on January 13 and July 13 of each year, commencing July 13, 2000. Interest
is computed on the basis of a 360-day year of twelve 30-day months.

Principal Payments

   The following table shows for each equipment group the principal amounts of
equipment notes issued with respect to each Basic Group:

Prepayments

   Mandatory Prepayments. If there is an Event of Loss, as defined in the
Leases and described below, with respect to one or more railcars, unless such
railcars are replaced within a 60-day period following notice of such Event of
Loss, all or a portion, as the case may be, of the equipment notes issued with
respect to the equipment group in which such railcars were included are
required to be prepaid. The prepayment is payable on the first Regular
Distribution Date that follows the date 25 days after the 60-day replacement
period elapses or, if earlier, 25 days after GATX Rail Corporation gives notice
of its election to pay the stipulated loss value of such railcars. However, if
payment of the stipulated loss value is so required with respect to an
aggregate of 15 or more railcars in such equipment group, then the prepayment
is required to be made on a Special Distribution Date occurring not less than
25 days after such notice. The prepayment price is the amount equal to the sum
of:

  (1) as to principal, an amount equal to the product obtained by multiplying
      the unpaid principal amount (as of such prepayment date) of the
      equipment notes issued with respect to the applicable railcars (after
      deducting therefrom the principal installment, if any, due on such
      date) by a fraction, the numerator of which shall be the cost of such
      equipment and the denominator of which shall be the aggregate cost of
      all equipment in such equipment group of the same car type immediately
      prior to such prepayment date; and

  (2) as to interest, the aggregate amount of interest accrued and unpaid in
      respect of the principal amount to be prepaid pursuant to clause (1)
      above on such prepayment date, but without the payment of any premium.
      See "Description of the Equipment Notes--The Leases--Events of Loss."
      (Lease, Sections 11.1 and 11.2; Indenture, Section 2.10(b))

   Voluntary Prepayments at the Option of GATX Rail Corporation. Each Owner
Trustee is required to prepay the applicable portion of the equipment notes
issued by such Owner Trustee if GATX Rail Corporation exercises its option to:

  (1) on or after April 13, 2007, terminate the Lease with respect to any
      railcars in the related equipment group; or

  (2) purchase any railcars in the related equipment group, which purchase
      option is exercisable on specified dates on or after July 13, 2010. The
      Owner Trustee will not be obligated to prepay the related equipment
      notes if GATX Rail Corporation elects to assume them on a full recourse
      basis.

   If a prepayment is required, it will be made on a Regular Distribution Date
(or, in certain limited circumstances, a Special Distribution Date) upon at
least 25 days' prior notice from the applicable Owner Trustee (or GATX Rail on
the applicable Owner Trustee's behalf) to the applicable Indenture Trustee. The
prepayment price is the unpaid principal amount thereof (computed as provided
in the preceding paragraph) together with accrued interest thereon to the date
of prepayment (computed as provided in the preceding paragraph) plus a premium
equal to the applicable Make-Whole Amount described below. The Owner Trustee
will fund the prepayment out of the net proceeds from the sale of such railcars
and, to the extent such proceeds are insufficient, with a portion of certain
payments received by the applicable Indenture Trustee from GATX Rail
Corporation, or with other moneys deposited with the Indenture Trustee by such
Owner Trustee. See "Description of the Equipment Notes--The Leases--
Termination," "--Special Purchase Option" and "--Early Purchase Option."
(Lease, Sections 10 and 22.1; Indenture, Section 2.10(a))

   GATX Rail Corporation also has a right to purchase the railcars if the
related owner participant or any of its affiliates become, acquire, or are
acquired by, merged or otherwise consolidated with any company or affiliate
engaged in full service railcar leasing, whether or not a direct competitor to
GATX Rail Corporation or any affiliate of GATX Rail Corporation or any person
that has a material interest (whether held directly or indirectly) in an
enterprise that engages in a business that is competitive with GATX Rail
Corporation's full service railcar leasing business. If this happens and GATX
Rail Corporation elects to exercise this right to purchase railcars, all of the
related equipment notes issued by the applicable Owner Trustee will be prepaid
on a Special Distribution Date, upon at least 25 days' prior notice from GATX
Rail Corporation to the applicable

                                      S-23
<PAGE>

Owner Trustee and the applicable Indenture Trustee. In this case, the required
prepayment price is the amount equal to the unpaid principal amount (computed
as provided in "Description of Equipment Notes--Prepayments--Mandatory
Prepayments") together with accrued interest thereon to the date of prepayment
(computed as provided in "Description of Equipment Notes--Prepayments--
Mandatory Prepayments") plus premium equal to the applicable Make-Whole Amount
described below, if any. Prepayment is not required if GATX Rail Corporation
assumes, on a full recourse basis, all of the Owner Trustee's obligations with
respect to the related equipment notes. (Participation Agreement, Section 6.9;
Indenture, Section 2.10(c))

   In the event of a refinancing of the equipment notes issued with respect to
any equipment group, all of the related equipment notes issued by the
applicable Owner Trustee will be prepaid on the date of such refinancing, which
may be any business day, upon at least 25 days' prior notice from the
applicable Owner Trustee to the Indenture Trustee. The prepayment price shall
be equal to the unpaid principal amount thereof, together with accrued interest
thereon, plus, the applicable premium, if any. The premium, if any, is the
applicable Make-Whole Amount described below. See "Description of the Equipment
Notes--The Participation Agreements." (Indenture, Section 2.10(c) and (d))

   Voluntary Prepayments at the Option of Owner Trustee. The applicable Owner
Trustee, at its option, has the right to purchase all, but not less than all,
of the equipment notes issued by the related owner trust, upon 30 days'
irrevocable notice, on a Special Distribution Date, if any of the following
occur:

  (1) an acceleration of the due dates of such equipment notes;

  (2) the applicable Indenture Trustee, as assignee of the related Lease, has
      declared such Lease to be in default and having commenced the exercise
      of any additional remedy in respect of the railcars under such Lease;
      or

  (3) one or more Lease Events of Default has occurred under the related
      Lease and continued for a period of 180 days or more during which
      period such equipment notes could, but shall not, have been accelerated
      by the applicable Indenture Trustee.

Such prepayment would be at a price equal to the aggregate unpaid principal
amount thereof and accrued interest on such equipment notes to the date of
payment, but without the payment of a premium. During such 30-day notice
period, the applicable Indenture Trustee shall not exercise any of the rights,
remedies or powers under the related Lease or the related Indenture so long as
the applicable Owner Trustee (or any nominee of the Owner Trustee reasonably
acceptable to the Indenture Trustee) has notified the Indenture Trustee that
such notice constitutes a binding obligation of the Owner Trustee to purchase
such equipment notes. (Indenture, Section 4.04(b))

   Make-Whole Amount. The Make-Whole Amount, if any, payable with respect to
the equipment notes will be determined by an independent investment banking
institution of national standing (the "Investment Banker") selected by GATX
Rail Corporation or, if the applicable Indenture Trustee does not receive
notice of such selection at least ten days prior to a scheduled prepayment date
or if a Lease Event of Default under the applicable Lease shall have occurred
and be continuing, selected by the applicable Indenture Trustee.

   The term "Make-Whole Amount" means, with respect to the principal amount of
any equipment note to be prepaid on any prepayment date, an amount to be
determined by the Investment Banker as of the third business day prior to the
applicable prepayment date, equal to the product obtained by multiplying:

  (1) the excess, if any, of (a) the sum of the present values of all the
      remaining scheduled payments of principal and interest from the
      prepayment date to maturity of such equipment note, discounted
      semiannually at a rate equal to the Treasury Rate plus 20 basis points,
      based on a 360-day year of twelve 30-day months, over (b) the aggregate
      unpaid principal amount of such equipment note plus any accrued but
      unpaid interest thereon, by

                                      S-24
<PAGE>

  (2) a fraction, the numerator of which shall be the principal amount of
      such equipment note to be prepaid on such prepayment date and the
      denominator of which shall be the aggregate unpaid principal amount of
      such equipment note; provided, that the aggregate unpaid principal
      amount of such equipment note for the purpose of clauses (1)(a) and (b)
      above shall be determined after deducting the principal installment, if
      any, due on such prepayment date.

   The "Treasury Rate" means, with respect to each equipment note to be
prepaid, a per annum rate (expressed as a semiannual equivalent and as a
decimal and, in the case of United States Treasury bills, converted to a bond
equivalent yield), determined to be the per annum rate equal to the semiannual
yield to maturity of United States Treasury securities maturing on the Average
Life Date (as defined below) of such equipment note, as determined by
interpolation between the most recent weekly average yields to maturity for two
series of United States Treasury securities:

  (1) one maturing as close as possible to, but earlier than, the Average
      Life Date of such equipment note; and

  (2) the other maturing as close as possible to, but later than, the Average
      Life Date of such equipment note, in each case as published in the most
      recent H.15(519) (or, if a weekly average yield to maturity of United
      States Treasury securities maturing on the Average Life Date of such
      equipment note is reported in the most recent H.15(519), as published
      in H.15(519)). "H.15(519)" means "Statistical Release H.15(519),
      Selected Interest Rates," or any successor publication, published by
      the Board of Governors of the Federal Reserve System. The most recent
      H.15(519) means the latest H.15(519) which is published prior to the
      close of business on the third business day preceding the scheduled
      prepayment date.

   The "Average Life Date" for an equipment note, measured as of a particular
prepayment date or other date of determination, is the last day of the period
constituting the Remaining Weighted Average Life of such equipment note on that
determination date.

   The "Remaining Weighted Average Life" of an equipment note, at the
prepayment or determination date of the equipment note, is the number of days
equal to the quotient obtained by dividing:

  (1) the sum of the products obtained by multiplying (a) the amount of each
      then remaining principal payment on such equipment note by (b) the
      number of days from and including the prepayment or determination date
      to but excluding the scheduled payment date of such principal payment,
      by

  (2) the unpaid principal amount of such equipment note.

Security

   The equipment notes issued with respect to each equipment group will be
equally and ratably secured by:

  (1) an assignment by the related Owner Trustee to the related Indenture
      Trustee of the Owner Trustee's rights (except for certain limited
      rights described below) under the Lease with respect to the equipment
      group, including the right to receive payments of rent thereunder, and

  (2) a perfected first priority security interest to the Indenture Trustee
      in the equipment group, subject to the rights of GATX Rail Corporation
      under the Lease.

See "Description of the Equipment Notes--Security" in the accompanying
prospectus. The assignment by the Owner Trustee to the related Indenture
Trustee of its rights under the Lease excludes, among other things, rights of
the Owner Trustee and the related owner participant relating to indemnification
by GATX Rail Corporation for certain matters, insurance proceeds payable to the
Owner Trustee in its individual capacity and to the owner participant under
liability insurance maintained by GATX Rail Corporation under the Lease or by
the Owner Trustee or the owner participant, insurance proceeds payable to the
Owner Trustee in its individual capacity or to the owner participant under
certain casualty insurance maintained by the Owner Trustee or the owner
participant under the Lease, and certain reimbursement payments made by GATX
Rail Corporation to the Owner Trustee. (Indenture, Granting Clause)

Indenture Events of Default, Notice and Waiver

   The following events are Events of Default under each Indenture:

  (1) a Lease Event of Default under the related Lease;

  (2) default by the related Owner Trustee in making payments when due of
      principal of, premium or interest on any equipment note and continuance
      of such default for 10 business days;

  (3) failure by the related Owner Trustee or the related owner participant
      to perform any covenant contained in the Indenture, the equipment notes
      issued thereunder or in the related Participation Agreement continued
      for a period of 30 days after written notice by the related Indenture
      Trustee or any holder of an equipment note issued under the Indenture;

  (4) any representation or warranty made by the related Owner Trustee in the
      Indenture or made by such Owner Trustee (except to the extent made with
      respect to Wilmington Trust Company, in its individual capacity) or the
      related owner participant in the related Participation Agreement or by
      any representative of the Owner Trustee or the owner participant in any
      document or certificate furnished to the related Indenture Trustee
      being incorrect in any material respect as of the date made and
      remaining material and continuing unremedied for a period of 30 days
      after written notice to the related Owner Trustee and related owner
      participant; and

  (5) the occurrence of certain events of bankruptcy, reorganization or
      insolvency of the related owner participant or the related Owner
      Trustee. There are no cross-default provisions in the Indentures and
      events resulting in an Indenture Event of Default under any particular
      Indenture or a default under any other indebtedness of GATX Rail
      Corporation will not necessarily result in an Indenture Event of
      Default under any other Indenture. (Indenture, Section 4.01)

   The Owner Trustee may, by giving 30 days' irrevocable notice, elect to
purchase all, but not less than all, of the equipment notes then outstanding
under the related Indenture if any of the following occur:

  (1) at any time one or more Lease Events of Default under the related Lease
      shall occur and shall have continued for a period of 180 days or more
      during which time the equipment notes issued under the related
      Indenture could, but shall not, have been accelerated;

  (2) such equipment notes shall have been accelerated; or

  (3) the related Indenture Trustee, as assignee of the related Lease, shall
      have declared such Lease to be in default and shall have commenced the
      exercise of any additional remedy in respect of the railcars under such
      Lease.

To exercise this purchase right, the Owner Trustee must pay the holders an
amount equal to the aggregate unpaid principal amount of all outstanding
equipment notes together with accrued and unpaid interest thereon to the date
of payment, but no premium is required to be paid. During the 30-day notice
period, the applicable Indenture Trustee shall not exercise any of the rights,
remedies or powers under the related Lease or the related Indenture so long as
the applicable owner participant (or any nominee of the applicable owner
participant reasonably acceptable to the Indenture Trustee) has notified the
Indenture Trustee that such notice constitutes a binding obligation of the
Owner Trustee to purchase such equipment notes. (Indenture, Section 4.04(b))

   In the event GATX Rail Corporation fails to make any semiannual basic rental
payment within 10 business days after the date such rental payment shall become
due under a Lease, then and as long as no other Indenture Event of Default
under the related Indenture (which is not being concurrently cured) shall have
occurred and be continuing, the applicable owner participant or the applicable
Owner Trustee may (but need not), during the 10 business days after receiving
written notice of such failure from the applicable Indenture Trustee, pay to
the applicable Indenture Trustee the amount of such rental payment together
with any interest thereon on account of the delayed payment, in which event
such payment by such owner participant or such Owner Trustee shall be deemed to
cure any Indenture Event of Default which arose from such failure of GATX

                                      S-26
<PAGE>

Rail Corporation (but such cure shall not relieve GATX Rail Corporation of any
of its obligations); provided, that the applicable owner participant and the
applicable Owner Trustee, collectively, shall not be entitled to cure more than
three consecutive or six total failures to make semiannual basic rental
payments.

   In the event there shall occur a Lease Event of Default under a Lease in
respect of any other payment of rent, or which is curable by the payment of
money, then and as long as no other Indenture Event of Default under the
related Indenture (which is not being concurrently cured) shall have occurred
and be continuing, the applicable owner participant or the applicable Owner
Trustee may, during the 30 days after receiving written notice of such Lease
Event of Default from the applicable Indenture Trustee, pay to such Indenture
Trustee the amount of such rental payment together with any interest thereon on
account of the delayed payment, or otherwise make such payment as shall effect
such cure, in which event such payment by such owner participant or such Owner
Trustee shall be deemed to cure any Indenture Event of Default which arose as a
result of such Lease Event of Default (but such cure shall not relieve GATX
Rail Corporation of any of its obligations); provided, that the applicable
owner participant and the applicable Owner Trustee, collectively, shall not be
entitled to cure such other Lease Events of Default if the unreimbursed amount
of such payments shall exceed $3 million.

   With respect to any amounts advanced by and owing to the applicable Owner
Trustee and the applicable owner participant, such Owner Trustee and such owner
participant shall be expressly subordinated to the rights of the holders of the
equipment notes to receive any and all amounts then due and owing on the
equipment notes prior to any payment from GATX Rail Corporation to such owner
participant or such Owner Trustee. (Indenture, Section 4.04(a))

   Each Indenture provides that the applicable Indenture Trustee shall, upon
the occurrence of any event known to it to be an Indenture Default or Indenture
Event of Default thereunder, give notice thereof to the applicable Trustee,
GATX Rail Corporation, the applicable Owner Trustee and the applicable owner
participant. (Indenture, Section 5.01)

   The holders of a majority in aggregate principal amount of the outstanding
equipment notes issued under an Indenture by notice to the related Indenture
Trustee may on behalf of all holders thereof waive any past default under such
Indenture except a default in the payment of the principal of, premium or
interest on any equipment note issued thereunder or a default in respect of any
covenant or provision of such Indenture that cannot be modified or amended
without the consent of each holder of an equipment note affected thereby.
(Indenture, Section 4.06)

Remedies

   If an Indenture Event of Default shall occur and be continuing under an
Indenture, the Indenture Trustee may, and when instructed by the holders of a
majority in aggregate principal amount of the equipment notes outstanding under
such Indenture shall, declare the unpaid principal of all such equipment notes
to be due and payable, together with all accrued interest. The holders of a
majority in aggregate principal amount of equipment notes outstanding under
such Indenture may annul any such declaration by the Indenture Trustee at any
time prior to the sale of the related equipment group after such an Indenture
Event of Default if:

  (1) there has been paid to or deposited with such Indenture Trustee an
      amount sufficient to pay all overdue installments of principal of and
      interest on the equipment notes outstanding under such Indenture that
      have become due otherwise than by such declaration of acceleration;

  (2) the rescission would not conflict with any judgment or decree; and

  (3) all other Indenture Defaults and Indenture Events of Default under such
      Indenture, other than nonpayment of principal and interest on the
      equipment notes outstanding under such Indenture that have become due
      solely because of such acceleration, have been cured or waived.
      (Indenture, Section 4.02)

                                      S-27
<PAGE>

   Each Indenture provides that, if an Indenture Event of Default has occurred
and is continuing, the Indenture Trustee may exercise certain rights or
remedies available to it under applicable law, including (if the related Lease
has been declared in default) one or more of the remedies under the Indenture
or the Lease with respect to the equipment group subject to the Lease. An
Indenture Trustee's right to exercise remedies under an Indenture is subject in
certain circumstances to the Indenture Trustee, as security assignee for the
applicable Owner Trustee, having proceeded to exercise one or more remedies
under the Lease with respect to the related equipment group, unless at the
time, the Indenture Trustee is stayed or otherwise prevented from doing so by
operation of law, in which case the Indenture Trustee has agreed to refrain
from exercising remedies under the Indenture for a period of not less than 90
days. Further, an Indenture Trustee may not exercise remedies under the
Indenture in those circumstances in which GATX Rail Corporation, as the debtor
in a bankruptcy proceeding, has assumed the Lease with the approval of the
bankruptcy court having jurisdiction over the case, under Section 365 of the
Bankruptcy Code or any amended or successor version thereof, and no Lease Event
of Default, other than a Lease Event of Default arising from the bankruptcy of
GATX Rail Corporation, has occurred and is continuing under the Lease and no
Indenture Event of Default unrelated to a Lease Event of Default occurring
solely as a result of the bankruptcy of GATX Rail Corporation has occurred and
is continuing under the Indenture. See "Description of the Equipment Notes--The
Leases--Lease Events of Default". Subject to the provisions of this paragraph,
such remedies may be exercised by an Indenture Trustee to the exclusion of a
related Owner Trustee and, subject to the terms of the related Lease, GATX Rail
Corporation. Any equipment sold in the exercise of such remedies will be free
and clear of any rights of those parties including the rights of GATX Rail
Corporation under the Lease with respect to the related equipment; provided
that no exercise of any remedies by the Indenture Trustee may affect the rights
of GATX Rail Corporation under the Lease unless a Lease Event of Default has
occurred and is continuing. (Indenture, Sections 4.03(a) and (c), 4.04(c) and
4.05; Lease, Section 15)

   The holders of a majority in aggregate principal amount of the equipment
notes outstanding under an Indenture may instruct the Indenture Trustee to give
notice, direction or consent, or exercise such right, remedy or power under the
Indenture or the related Lease or in respect of the Indenture estate or take
such other action as shall be specified in such instructions, but the Indenture
Trustee shall not be required to take or refrain from taking any action in
connection therewith if it shall have reasonable grounds for believing that
adequate indemnity against the risk of taking the action is not reasonably
assured to it. (Indenture, Sections 5.02 and 5.03)

   If an Indenture Event of Default occurs and is continuing under an Indenture
and the Indenture Trustee thereunder (as security assignee) has declared the
related Lease to be in default or the equipment notes outstanding under such
Indenture have been accelerated or such Indenture Trustee has exercised any
remedies under such Indenture, any sums held or received by the Indenture
Trustee may be applied to reimburse the Indenture Trustee for any tax, expense
or other loss incurred by it and to pay any other amounts then due to the
Indenture Trustee prior to any payments to holders of the equipment notes
issued under the Indenture. (Indenture, Section 3.03)

Modification of Indentures and Leases

   Without the consent of holders of a majority in aggregate principal amount
of the equipment notes outstanding under an Indenture, the provisions of such
Indenture and the related Lease and the related Participation Agreement may not
be amended or modified, except to the extent indicated below.

   Certain provisions of each Lease and each Participation Agreement may be
amended or modified by the parties thereto without the consent of any holders
of the equipment notes outstanding under such Indenture so long as no Indenture
Event of Default thereunder shall have occurred and be continuing. In the case
of each Lease, such provisions include, among others, provisions relating to:

  (1) rental payments and other payments, except to the extent indicated in
      item (1) of the following paragraph and except such payments may not be
      reduced below the level necessary to pay in full all scheduled payments
      of principal of, premium and interest on the related equipment notes
      when due;

                                      S-28
<PAGE>

  (2) the maintenance of the equipment group covered by such Lease,
      modifications to the equipment within such equipment group and the
      return to the related Owner Trustee of such equipment group at the end
      of the term of such Lease; and

  (3) the renewal of such Lease and the option of GATX Rail Corporation at
      the end of the term of such Lease to purchase such equipment group.
      (Indenture, Section 9.05)

   Without the consent of the holder of each equipment note outstanding under
an Indenture, no amendment or modification of such Indenture may:

  (1) change the final maturity of, or reduce the principal amount of,
      premium or interest payable on any equipment notes issued under such
      Indenture or impair the right to institute suit for the enforcement of
      any such payment or change the date on which any principal, premium or
      interest is due and payable;

  (2) create any lien with respect to the property subject to the lien of
      such Indenture ranking prior to or on a parity with the security
      interest created by such Indenture, except as permitted in such
      Indenture, or deprive any holder of an equipment note issued under such
      Indenture of the benefit of the lien of such Indenture; or

  (3) reduce the percentage in principal amount of outstanding equipment
      notes issued under such Indenture necessary to modify or amend any
      provision of such Indenture or to waive compliance therewith.
      (Indenture, Section 9.01(b))

Assumption of Equipment Notes under Certain Circumstances

   In the event that GATX Rail Corporation elects to purchase any or all of an
equipment group prior to the maturity of the related equipment notes, either
pursuant to the early purchase option described under "--The Leases--Early
Purchase Option" or as a result of the related owner participant or any
affiliate thereof engaging in a business in competition with GATX Rail
Corporation's full service railcar leasing business as described under "--The
Participation Agreements," GATX Rail Corporation will have the right to assume
the related equipment notes on a full recourse basis. Such assumption is
subject to certain terms and conditions, including, among other things:

  (1) delivery by GATX Rail Corporation of an indenture supplement giving
      effect to such assumption reasonably satisfactory to the related
      Indenture Trustee and execution and delivery by GATX Rail Corporation
      of equipment notes reflecting such assumption;

  (2) delivery by GATX Rail Corporation to the related Indenture Trustee and
      the related Owner Trustee of a certificate stating that GATX Rail
      Corporation has paid to such Owner Trustee all amounts required to be
      paid to such Owner Trustee pursuant to the applicable Lease in
      connection with such purchase and assumption;

  (3) there being no Indenture Event of Default or event which with notice or
      lapse of time or both would become an Indenture Event of Default has
      occurred and is continuing immediately subsequent to such assumption;
      and

  (4) receipt by the related Indenture Trustee and the related Owner Trustee
      of an opinion of counsel to GATX Rail Corporation to the effect that,
      after giving effect to the indenture supplement:

    (a) the related Indenture, the indenture supplement and the equipment
        notes issued thereunder each constitutes a legal, valid and binding
        obligation of GATX Rail Corporation, enforceable against GATX Rail
        Corporation in accordance with their respective terms (subject to
        customary exceptions);

    (b) all filings and recordings and other action necessary or
        appropriate to protect the interests of the related Indenture
        Trustee in the equipment purchased by GATX Rail Corporation have
        been accomplished; and

    (c) no holder of equipment notes will be required to recognize gain or
        loss for tax purposes in connection with such assumption.

                                      S-29
<PAGE>

   Following such assumption, the equipment so purchased by GATX Rail
Corporation shall remain subject to the lien of the Indenture securing the
related equipment notes but the related Owner Trustee shall be released from
all obligations under such equipment notes and under the related Indenture in
respect of such equipment notes. (Indenture, Section 3.06; Lease, Section 22.1;
and Participation Agreement, Section 6.9)

The Leases

   Term and Rentals. Each equipment group will be leased separately by the
related Owner Trustee to GATX Rail Corporation for a term commencing on the
date of delivery of the railcars to such Owner Trustee and expiring on July 13,
2021, unless previously terminated as permitted by the related Lease.

   The basic rental payments by GATX Rail Corporation under each Lease will be
payable on each January 13 and July 13 (or, if such day is not a business day,
on the next succeeding business day), commencing July 13, 2000. These rental
payments will be used to fund payments of principal of and interest due on the
equipment notes issued under the related Indenture, which funds will in turn be
distributed by the Trustee to the Certificateholders on January 13 and July 13
of each year, commencing July 13, 2000. (Lease, Section 3.2; Indenture, Section
3.01)

   Basic rental payments that GATX Rail Corporation is obligated to make or
cause to be made under each Lease will not be less than the scheduled payments
of principal of and interest on the equipment notes issued under the Indenture
relating to such Lease. In certain cases, the semiannual basic rental payments
under each Lease may be adjusted, but under no circumstances will such rental
payments be less than the scheduled payments of principal of and interest on
the equipment notes issued under the Indenture relating to such Lease. The
balance of any such semiannual basic rental payment under each Lease, after
payment of the scheduled principal of and interest on the equipment notes
issued under the Indenture relating to such Lease, will be paid over to or for
the account of the related owner participant as the beneficial owner of the
equipment group covered by such Lease. (Indenture, Section 3.01; Lease, Section
3; Trust Agreement, Section 3.2)

   Sublease; Possession and Use. GATX Rail Corporation is in the business of
leasing railcars to third parties under operating leases. The terms of these
leases vary based on the needs of the sublessee and GATX Rail Corporation. GATX
Rail Corporation shall have the right to sublease the equipment to any railroad
company incorporated in the United States, Canada or Mexico or to any other
responsible company which is not a railroad company for use in its business;
provided that GATX Rail Corporation may not sublease more than 15% of the
railcars within any equipment group to a sublessee formed under the laws of
Mexico or any state thereof. Each Lease provides that the railcars are to be
used primarily on domestic routes in the United States and that at no time
shall more than 35% of the railcars within any equipment group (as determined
by mileage records) be used outside the United States at the same time until
January 1, 2007. Thereafter, no more than 49% of the railcars within any
equipment group (as determined by mileage records) may be used outside the
continental United States (exclusive of Alaska) at the same time.
Notwithstanding the foregoing, each Lease provides that no more than 15% of the
railcars within any equipment group may be used in Mexico so long as Mexican
law does not afford protection to the applicable Owner Trustee and the
applicable Indenture Trustee comparable to United States law. GATX Rail
Corporation may not sublease any railcars for a term which extends beyond the
term of the related Lease unless GATX Rail Corporation replaces such railcars
on or prior to the expiration of the related Lease term in accordance with the
provisions of such Lease. No sublease will discharge GATX Rail Corporation of
its obligations under the related Lease. If any railcar is leased or the
possession is otherwise transferred, such railcar will remain subject to the
lien of the related Indenture. (Lease, Section 8.2 and 8.3)

   Liens. Each equipment group will be maintained free of any liens, other than
the rights of the related owner participant, the related Owner Trustee, the
related Indenture Trustee, the holders of the related equipment notes, GATX
Rail Corporation and any permitted sublessee arising under the related Lease,
the related Indenture, the related Participation Agreement or the related Trust
Agreement between such Owner Trustee and such owner participant pursuant to
which such Owner Trustee acts as trustee for the benefit of such

                                      S-30
<PAGE>

owner participant, and other than, in the case of such equipment group, certain
limited liens permitted under the related Lease and related Indenture,
including liens for taxes either not yet due and payable or being contested (so
long as there exists no material risk of sale, forfeiture, loss or loss of use
of such equipment group or any interest therein), materialmen's, mechanics' and
other similar liens arising in the ordinary course of business and either not
yet due and payable or being contested (so long as there exists no material
risk of sale, forfeiture, loss or loss of use of such equipment group),
judgment liens that are being appealed and whose enforcement has been stayed
pending such appeal, and salvage rights of insurers. (Lease, Section 7;
Participation Agreement, Sections 6.4(a) and 6.4(b))

   Termination. So long as no Lease Event of Default (or certain specified
events which with notice or lapse of time or both would become a Lease Event of
Default) thereunder shall have occurred and be continuing, GATX Rail
Corporation may terminate each Lease at its option any time on or after April
13, 2007 with respect to any or all of the railcars within the related
equipment group (provided that if such termination is for less than all of the
railcars in a Basic Group, GATX Rail Corporation shall exercise such
termination with respect to at least 25 railcars within the related equipment
group, no fewer than 25 railcars shall remain in such Basic Group following
such termination and the determination as to which railcars are subject to
termination shall be made by GATX Rail Corporation on a random or other basis
(in each case reasonably acceptable to the related Owner Trustee) without
regard to maintenance status, operating condition or otherwise) (the
"Terminated Units") if GATX Rail Corporation determines in good faith (as
evidenced by a certified copy of a resolution adopted by its Board of Directors
and a certificate executed by the Chief Financial Officer of GATX Rail
Corporation), that such Terminated Units have become obsolete or surplus to its
requirements. GATX Rail Corporation is required to give notice to the related
Owner Trustee and the related Indenture Trustee of its intention to exercise
its right of termination at least 120 days prior to the proposed date of
termination, which date shall be a Regular Distribution Date (or in certain
circumstances, a Special Distribution Date). GATX Rail Corporation will act as
agent for the related Owner Trustee in obtaining bids for the Terminated Units
and, if GATX Rail Corporation succeeds in locating the eventual purchaser of
the Terminated Units, the related Owner Trustee shall transfer on the
termination date all of its right, title and interest in and to the Terminated
Units to the bidder which has submitted the highest cash bid (who may not be
GATX Rail Corporation or any affiliate of GATX Rail Corporation but who may be
the related Owner Trustee or any affiliate of the related Owner Trustee). The
net proceeds of such sale shall be paid to the related Owner Trustee. If the
net proceeds received from such sale are less than a specified termination
value for the Terminated Units, GATX Rail Corporation shall pay to the related
Owner Trustee an amount equal to the difference between such proceeds and the
termination value. GATX Rail Corporation shall also pay to the related Owner
Trustee certain other amounts including all unpaid rent with respect to the
terminated railcars due on or prior to such termination and the applicable
premium. All funds to be paid to or deposited with the related Owner Trustee as
described in this paragraph shall, so long as the related Indenture shall not
have been discharged, be deposited directly with the related Indenture Trustee.
Amounts in excess of the outstanding principal amount of the equipment notes
issued in respect of such Terminated Units, the applicable premium thereon, and
the then accrued and unpaid interest thereon will be distributed by the related
Indenture Trustee in accordance with the terms of the related Indenture. The
lien of the related Indenture shall terminate with respect to the Terminated
Units after the full termination value has been received by the related
Indenture Trustee and, if all amounts due the related owner participant have
also been paid, the related Lease shall terminate with respect to such
Terminated Units and thereafter the obligation of GATX Rail Corporation to make
basic rental payments with respect thereto shall cease. In the event any
Terminated Unit is not sold by its proposed termination date, the Lease
relating thereto, including all GATX Rail Corporation's obligations thereunder,
shall continue in effect. (Lease, Sections 3.6, 10.1, 10.2 and 10.4; Indenture,
Section 3.02)

   The Owner Trustee with respect to the applicable equipment group shall have
the option to retain the Terminated Units, but it may do so only if such Owner
Trustee pays, or causes to be paid, to the related Indenture Trustee funds in
an amount equal to the principal of and accrued interest on the outstanding
equipment notes issued with respect to such Terminated Units and an amount
equal to the premium. (Lease, Section 10.3)

   Special Purchase Option. So long as no Lease Event of Default (or certain
specified events which with notice or lapse of time or both would become a
Lease Event of Default) has occurred and is continuing under the related Lease
(subject to certain exceptions), GATX Rail Corporation may purchase, at its
option, exercisable on the date specified below, any or all of the railcars
contained in the related equipment group at a price equal to the greater of the
then applicable termination value for such railcars and the then fair market
sales value for such railcars, provided that if GATX Rail Corporation elects to
purchase some but less than all of the railcars in a Basic Group, after giving
effect to such purchase, no fewer than 425 railcars shall be subject to the
related Lease, the allocation of railcars (by Basic Group) shall be
substantially similar to the allocation immediately prior to such purchase, and
no Basic Group shall have less than 25 railcars, and provided further, the
determination as to which railcars are to be purchased shall be made on a
random or other basis (in each case reasonably acceptable to the related Owner
Trustee) without regard to maintenance status, operating condition or
otherwise. GATX Rail Corporation's special purchase option shall be exercisable
on July 13, 2010. GATX Rail Corporation is required to give irrevocable notice
to the related Owner Trustee not less than 90 days prior to such date of its
election to exercise the early purchase option described herein. So long as the
related Indenture shall not have been discharged, the amount of the special
purchase price shall be deposited by GATX Rail Corporation directly with the
related Indenture Trustee unless GATX Rail Corporation exercises its right to
assume all obligations of the Owner Trustee under the equipment notes issued in
respect of such railcars. Amounts in excess of the outstanding principal amount
of the equipment notes issued in respect of such railcars and the then accrued
and unpaid interest thereon will be distributed by the related Indenture
Trustee in accordance with the terms of the related Indenture. The lien of the
related Indenture shall terminate with respect to such railcars after the
special purchase price and all other amounts due and owing by GATX Rail
Corporation with respect to such railcars have been paid. (Lease, Sections 3.6
and 22.1(a) and (c); Indenture, Sections 3.02 and 10.01)

   Early Purchase Option. So long as no Lease Event of Default (or certain
specified events which with notice or lapse of time or both would become a
Lease Event of Default) shall have occurred and be continuing under the related
Lease (subject to certain exceptions), GATX Rail Corporation may purchase, at
its option, exercisable on a specified date for each Basic Group, any or all of
the railcars contained in the related group at a price equal to the early
purchase price of such railcars, provided that if GATX Rail Corporation elects
to purchase some but less than all of the railcars in a Basic Group, GATX Rail
Corporation must exercise such purchase option with respect to at least 25
railcars within the related equipment group, no fewer than 25 railcars must
remain in such Basic Group as a result of such purchase and the determination
as to which railcars are to be purchased must be made on a random or other
basis (in each case reasonably acceptable to the related Owner Trustee) without
regard to maintenance status, operating condition or otherwise. GATX Rail
Corporation's early purchase option is exercisable on specified dates on or
after July 13, 2017. GATX Rail Corporation is required to give irrevocable
notice to the related Owner Trustee not less than 90 days prior to such date of
its election to exercise the early purchase option described herein. So long as
the related Indenture shall not have been discharged, the amount of the early
purchase price shall be deposited by GATX Rail Corporation directly with the
related Indenture Trustee unless GATX Rail Corporation exercises its right to
assume all obligations of the Owner Trustee under the equipment notes issued in
respect of such railcars. Amounts in excess of the outstanding principal amount
of the equipment notes issued in respect of such railcars plus the applicable
premium and the then accrued and unpaid interest will be distributed by the
related Indenture Trustee in accordance with the terms of the related
Indenture. The lien of the related Indenture shall terminate with respect to
such railcars after the early purchase price and all other amounts due and
owing by GATX Rail Corporation with respect to such railcars have been paid.
(Lease, Sections 3.6 and 22.1(b) and (c); Indenture, Sections 3.02 and 10.01)

   Events of Loss. If an Event of Loss occurs with respect to a railcar, GATX
Rail Corporation shall give notice thereof to the related Owner Trustee and
within 60 days after such notice make an election to either:

  (1) pay to such Owner Trustee the stipulated loss value of such railcar,
      together with certain additional amounts, or

                                      S-32
<PAGE>

  (2) if no Lease Event of Default under the applicable Lease has occurred
      and is continuing, replace such railcar.

   In the event GATX Rail Corporation elects to replace such railcar, it must
do so within 60 days after GATX Rail Corporation gives notice of such Event of
Loss with a railcar of the same car type of the same or newer model year (or
otherwise approved by the related Owner Trustee, which approval shall not be
unreasonably withheld), and having a fair market value, utility, capacity,
remaining economic useful life and condition at least equal to the railcar so
replaced (assuming such railcar was in the condition required to be maintained
by the applicable Lease). If GATX Rail Corporation elects to pay the stipulated
loss value of a railcar subject to an Event of Loss or fails to replace such
railcar within such 60-day period, it must pay the stipulated loss value with
respect to such railcar on the Regular Distribution Date which next succeeds
the 25th day following the date of notice of GATX Rail Corporation's election
to pay the stipulated loss value (or if payment of the stipulated loss value is
so required with respect to an aggregate of fifteen or more railcars in such
equipment group, then on the Special Distribution Date which next succeeds the
25th day following the date such prepayment becomes required). Upon making such
payment, together with certain additional amounts, which in all circumstances
will be at least sufficient to pay in full as of the date of payment thereof
that portion of the aggregate unpaid principal of the outstanding equipment
notes issued with respect to such railcar, together with all unpaid interest
thereon accrued to the date on which such amount is paid, but without the
payment of any premium, the lien of the related Indenture and the related Lease
shall terminate with respect to such railcar, title thereto shall be
transferred to GATX Rail Corporation or its designee and the obligation of GATX
Rail Corporation thereafter to make rental payments with respect thereto shall
cease. The stipulated loss value and other payments made by GATX Rail
Corporation shall be deposited with the related Indenture Trustee. Amounts in
excess of the outstanding principal amount of the equipment notes issued under
the related Indenture and the then accrued and unpaid interest thereon to be
prepaid as a result of such Event of Loss will be distributed by the related
Indenture Trustee in accordance with the terms of the related Indenture.
(Lease, Sections 3.6 and 11.2; Indenture, Sections 3.02 and 10.01)

   An Event of Loss with respect to any railcar shall mean any of the following
events:

  (1) damage or contamination of such railcar which, in GATX Rail
      Corporation's reasonable judgment (as evidenced by an officers'
      certificate to such effect), makes repair uneconomic or renders such
      railcar unfit for commercial use;

  (2) destruction, theft or disappearance of such railcar for a period
      exceeding twelve months (or, if earlier, the end of the term of the
      applicable Lease);

  (3) the permanent return of such railcar to the manufacturer pursuant to
      any patent indemnity provisions;

  (4) the taking or appropriating of title to such railcar by any
      governmental authority under the power of eminent domain or otherwise;
      or

  (5) the taking or requisitioning of such railcar for use by (a) any
      governmental authority of Mexico or any agency or instrumentality of
      the Mexican government if such taking or requisition is for a period in
      excess of (i) 365 days and (ii) the remaining basic term or any renewal
      term then in effect or (b) any other governmental agency or
      instrumentality for a period in excess of the remaining basic term or
      any renewal term then in effect. (Lease, Section 11.1)

   Lease Events of Default. Events of default under each Lease (each, a "Lease
Event of Default") include, among other things:

  (1) failure by GATX Rail Corporation to make any payment of basic rent, any
      purchase price to be paid by GATX Rail Corporation for any railcar
      pursuant to the Lease or the related Participation Agreement, any
      payment of stipulated loss value or any payment of termination value,
      within 10 business days after the same shall have become due;

  (2) failure by GATX Rail Corporation to make any payment of supplemental
      rent, including indemnity or tax indemnity payments, but not including
      stipulated loss value or any purchase price to be paid by

                                      S-33
<PAGE>

     GATX Rail Corporation for any railcar pursuant to the Lease or the
     related Participation Agreement, after the same shall have become due
     and such failure shall continue unremedied for 10 business days after
     receipt by GATX Rail Corporation of written notice of such failure from
     the related Owner Trustee, the related owner participant or the related
     Indenture Trustee;

  (3) failure to maintain in effect insurance as required by the Lease, such
      failure not having been waived;

  (4) unauthorized assignment or transfer of the Lease by GATX Rail
      Corporation or the permitting by GATX Rail Corporation of any
      possession of all or some of the equipment group not authorized by the
      Lease, provided that such unauthorized possession shall not constitute
      a Lease Event of Default for a period of 45 days after the occurrence
      thereof so long as:

    (a)  such unauthorized possession is not the result of any willful
         action of GATX Rail Corporation, and

    (b) such unauthorized possession is capable of being cured and GATX Rail
        Corporation diligently pursues such cure throughout such 45-day
        period;

  (5) failure by GATX Rail Corporation to observe or perform any of the
      agreements or covenants relating to the merger, consolidation or
      transfer of assets of GATX Rail Corporation and such failure continues
      unremedied for 30 days during which period GATX Rail Corporation
      diligently pursues the cure of such failure;

  (6) failure by GATX Rail Corporation to perform or observe any other
      covenant or agreement to be performed or observed by it under any
      Lessee Agreement (other than the Tax Indemnity Agreement) and such
      failure continues unremedied for 30 days after notice of such failure
      from the related Owner Trustee, the related owner participant or the
      related Indenture Trustee, or, if such failure is capable of being
      remedied (and the remedy requires an action other than, or in addition
      to, the payment of money), for a period of 90 days after receipt of
      such notice so long as GATX Rail Corporation is diligently proceeding
      to remedy such failure;

  (7) any representation or warranty made by GATX Rail Corporation in any
      Lessee Agreement (other than the Tax Indemnity Agreement) being untrue
      or incorrect in any material respect at the time made and such untruth
      or incorrectness continues to be material and unremedied for a period
      of 30 days after notice thereof from the related Owner Trustee, the
      related owner participant or the related Indenture Trustee or, if such
      untruth or incorrectness is capable of being remedied, for a period of
      60 days after receipt of such notice so long as GATX Rail Corporation
      is diligently proceeding to remedy such untruth or incorrectness and
      any adverse effects thereof; and

  (8) the occurrence of certain events of bankruptcy, reorganization or
      insolvency of GATX Rail Corporation.

There are no cross-default provisions in the Leases and events resulting in a
Lease Event of Default under any particular Lease will not necessarily result
in a Lease Event of Default under any other Lease. (Lease, Section 14)

   If a Lease Event of Default under any Lease has occurred and is continuing
and such Lease has been declared to be in default (or deemed to have been
declared in default), the related Indenture Trustee, as assignee of the
related Owner Trustee's rights under such Lease, may, subject to a stay of
such rights if GATX Rail Corporation were to become a debtor in a bankruptcy
or reorganization case under the Bankruptcy Code, exercise one or more of the
remedies provided in such Lease with respect to the equipment subject thereto.
These remedies include the right to repossess the railcar, to terminate the
Lease and any sublease thereunder and to require GATX Rail Corporation to pay
as liquidated damages any unpaid rent plus, at the related Indenture Trustee's
option, any one of the following amounts:

  (1) the excess of the present value of all rental payments for such railcar
      for the remainder of the basic term or any renewal term then in effect
      over the present value of the then fair market rental value of such
      railcar;

                                     S-34
<PAGE>

  (2) the excess of the stipulated loss value of such railcar over the fair
      market sales value of such railcar; or

  (3) the higher of the stipulated loss value for such railcar or the fair
      market sales value of such railcar. If payment is made pursuant to the
      foregoing clause (3), such railcar shall be transferred to GATX Rail
      Corporation. (Lease, Section 15)

The Participation Agreements

   GATX Rail Corporation is required to indemnify each owner participant, each
Owner Trustee, each Indenture Trustee and the Trustee for certain losses, fees
and expenses and for certain other matters. (Participation Agreement, Section
7.2) In addition, GATX Rail Corporation is required to indemnify each owner
participant, each Owner Trustee and each Indenture Trustee for certain taxes in
connection with the ownership, lease, sale or use of the equipment.
(Participation Agreement, Section 7.1)

   Each Participation Agreement gives GATX Rail Corporation certain rights to
repurchase the equipment group if the related owner participant or any
affiliate thereof is or acquires, is acquired by, merges or otherwise
consolidates with any company or affiliate thereof engaged in full service
railcar leasing, whether or not a direct competitor to GATX Rail Corporation or
any affiliate of GATX Rail Corporation, or any person that has a material
interest in an enterprise that engages in a business that is competitive with
GATX Rail Corporation's full service railcar leasing business. If any such
event occurs and GATX Rail Corporation elects to exercise its repurchase right,
GATX Rail Corporation is required to give notice to the related Owner Trustee
and the related Indenture Trustee. The purchase date would be the first Special
Distribution Date that occurs after the 25th day following the date of notice.
GATX Rail Corporation would be entitled to purchase such equipment for a
purchase price equal to either:

  (1) the termination value for such equipment group calculated as of such
      Special Distribution Date, together with all other amounts due and
      owing by GATX Rail Corporation with respect to such equipment group,
      including, without limitation, all accrued and unpaid rental payments
      and any Make-Whole Amount, or

  (2) if GATX Rail Corporation has elected to assume on a full recourse basis
      all of the related Owner Trustee's obligations in respect of the
      equipment notes issued with respect to such equipment group, the
      difference between the termination value for such equipment group and
      the outstanding principal amount of the equipment notes issued with
      respect to such equipment group.

If GATX Rail Corporation elects to exercise its right to purchase an equipment
group, unless GATX Rail Corporation elects to assume the related equipment
notes on a full recourse basis, the purchase price shall be used to prepay the
equipment notes issued with respect to such equipment group and to pay the
applicable Make-Whole Amount, if any, shall be paid. See "Description of the
Equipment Notes--Prepayment." (Participation Agreement, Section 6.9)

   Under each Participation Agreement, GATX Rail Corporation will be prohibited
from consolidating or merging with or into any other corporation or
transferring all or substantially all of its assets to another corporation
unless:

  (1) the successor corporation, if other than GATX Rail Corporation, shall
      be a corporation organized and existing under the laws of the United
      States or any state or the District of Columbia and shall expressly
      assume the due and punctual performance and observance of all the
      covenants and conditions of the operative agreements to be performed by
      GATX Rail Corporation;

  (2) immediately prior to and immediately after giving effect to such
      transaction, no Lease Event of Default under the related Lease, or
      event which with notice or the passage of time or both would become a
      Lease Event of Default under the related Lease, shall have occurred,
      whether as a result of such transaction or otherwise;

                                      S-35
<PAGE>

  (3) GATX Rail Corporation shall have made all filings necessary or
      appropriate in the reasonable opinion of the related Owner Trustee and
      the related Indenture Trustee in order to preserve and protect the
      rights of the related Owner Trustee under the related Lease and of the
      related Indenture Trustee under the related Indenture;

  (4) there shall have been delivered to the applicable owner participant,
      the applicable Owner Trustee and the applicable Indenture Trustee, an
      officer's certificate of the successor to GATX Rail Corporation (or
      such person as is the surviving corporation) and an opinion of counsel
      (which may be such person's in-house counsel) in form and substance
      reasonably satisfactory to such owner participant, such Owner Trustee
      and such Indenture Trustee, each stating that such consolidation,
      merger, conveyance, transfer or lease and the applicable assumption
      agreement comply with the terms of the applicable Participation
      Agreement; and

  (5) if the person (a) formed by such consolidation or surviving such merger
      (if other than GATX Rail Corporation) or the person which acquires all
      or substantially all of the assets of GATX Rail Corporation is not an
      affiliate of GATX Rail Corporation, the aggregate net worth of such
      surviving or acquiring person immediately after such merger,
      consolidation or acquisition (determined in accordance with generally
      accepted accounting principles) shall not be less than the consolidated
      net worth of GATX Rail Corporation immediately prior to such merger,
      consolidation or acquisition, or (b) with which GATX Rail Corporation
      consolidates or merges or which acquires all or substantially all of
      the assets of GATX Rail Corporation is an affiliate of GATX Rail
      Corporation, such person, immediately prior to such consolidation,
      merger or acquisition, has a positive net worth (determined in
      accordance with generally accepted accounting principles).
      (Participation Agreement, Section 6.8)

                              ERISA CONSIDERATIONS

   The United States Department of Labor has granted to Morgan Stanley & Co.
Incorporated an administrative exemption (Prohibited Transaction Exemption 90-
24, Exemption Application No. D-8019, 55 Fed. Reg. 20,548 (1990), as amended by
Prohibited Transaction Exemption 97-34, (62 Fed. Reg. 39,021 (1997)) (the
"Exemption") from certain of the prohibited transaction rules of ERISA and the
Code with respect to the purchase, both upon their initial issuance and in the
secondary market, the holding and the subsequent resale by an employee benefit
plan of certificates in certain pass through trusts, the assets of which
consist of secured credit instruments that bear interest, including qualified
equipment notes secured by leases. A number of conditions must be satisfied in
order for the Exemption to apply, including the requirement that the
certificates have, at the time of their purchase by an employee benefit plan, a
specified credit rating. Under the Exemption, an equipment note secured by a
lease will be considered qualified only if it is a note (a) which is secured by
equipment which is leased, (b) which is secured by the obligation of the lessee
to pay rent under the equipment lease and (c) with respect to which the trust's
security interest is at least as protective of the rights of the trust as the
trust would have if the equipment note were secured only by the equipment and
not by the lease. Any plan that purchases a Certificate must be an "accredited
investor" as defined in Rule 501(a)(1) of Regulation D promulgated under the
Securities Act. The Exemption from Section 406(b) or 407(a) of ERISA does not
apply to the acquisition, holding or disposition of Certificates by plans
sponsored by GATX Rail Corporation, the underwriters, the Trustee, the Owner
Trustees, the owner participants or any of their affiliates.

   It is not clear whether the Exemption applies to participant directed plans
described in Section 404(c) of ERISA or plans that are subject to Section 4975
of the Code but that are not subject to Title I of ERISA, such as certain Keogh
plans and certain individual retirement accounts. In addition, there are
various other terms and conditions to the applicability of the Exemption.
Accordingly, each fiduciary of a Plan should independently determine if its
purchase of a Certificate will require an exemption and, if so, whether the
Exemption applies to its purchase, or whether any other prohibited transaction
exemption is available. See "ERISA Considerations" in the accompanying
prospectus.

                              CERTAIN TAX ASPECTS

   The following discussion of the material United States federal income tax
consequences of the purchase, ownership and disposition of the Certificates is
directed to initial purchasers of the Certificates at the "issue price" who
hold the Certificates as a capital asset. This discussion is based on current
provisions of the Internal Revenue Code of 1986, as amended, called the "Code",
proposed, temporary and final Treasury Regulations under the Code, and
published rulings and court decisions, in effect as of the date of this
prospectus. Changes to existing tax laws, regulations, rulings and court
decisions, which could have retroactive effect, may alter the consequences
described below. This discussion does not address federal income tax
consequences applicable to investors that are subject to special treatment
under the United States federal income tax laws, including banks and thrifts,
insurance companies, regulated investment companies, dealers in securities,
holders that will hold the Certificates as a position in a "straddle" for tax
purposes or as part of a "synthetic security" or "conversion transaction" or
other integrated investment comprised of the Certificates and one or more other
investments, foreign investors, trusts or estates and pass-through entities
with any of these specified investors as equity holders. You should consult
your own tax advisors about the application of the United States federal income
tax laws to your particular situation as well as any tax consequences arising
under the laws of any state, local or foreign jurisdiction. The Trust is not
indemnified for any federal income taxes that may be imposed upon it. Any
income taxes imposed on a Trust could result in a reduction in amounts
available for distribution to Certificateholders.

   Vedder, Price, Kaufman & Kammholz, counsel to GATX Rail Corporation, has
advised GATX Rail Corporation that, in its opinion, based upon its
interpretation of analogous authorities under currently applicable law, the
Trust will not be classified as an association taxable as a corporation, but
should be classified as a grantor trust under the Code, and that each
Certificateholder will be treated as the owner of a pro rata undivided interest
in each of the equipment notes or any other property held in the Trust.

General

   Each Certificateholder will be required to report on its federal income tax
return its pro rata share of the gross income from each of the equipment notes
and any other property held in the Trust under the Certificateholder's usual
method of accounting. Each Certificateholder may deduct, consistent with its
method of accounting, its pro rata share of the fees and expenses paid or
incurred by the Trust as provided in Section 162 or 212 of the Code. Some fees
and expenses may, however, be borne by parties other than the
Certificateholders. The Trust may be treated as having constructively received
these fees and expenses so that each Certificateholder would be required to
include in income and would be entitled to deduct its pro rata share of these
constructively-received fees and expenses. Certificateholders who are
individuals, estates or trusts will be allowed to deduct expenses only to the
extent they exceed, together with the Certificateholder's other miscellaneous
itemized deductions, 2% of the Certificateholder's adjusted gross income. This
deduction may be reduced further by Section 68 of the Code if an individual's
adjusted gross income exceeds specified levels.

   If an equipment note held by a Trust is prepaid for an amount that differs
from a Certificateholder's aggregate adjusted basis in the equipment note, the
Certificateholder will be considered to have sold his pro rata share of that
equipment note, and will recognize any gain or loss equal to the difference
between the Certificateholder's adjusted basis and the amount realized from the
prepayment. However, any amount realized from prepayment which is attributable
to accrued interest would be taxable as interest income if not previously
included in income. A Certificateholder's adjusted basis is determined by
allocating the purchase price for the Certificate among the equipment notes and
other property in the Trust in proportion to their fair market values at the
time of purchase of the Certificate. Any gain or loss will be long-term capital
gain or loss if the equipment note has been held for more than one year. Net
capital gains of individuals are, in general, taxed at lower rates than items
of ordinary income. An owner participant's conveyance of its interest in an
owner trust will not constitute a taxable event to the holders of interests in
the equipment notes. However, if GATX Rail Corporation were to assume an owner
trust's obligations under the equipment notes the assumption may be

                                      S-37
<PAGE>

treated for federal income tax purposes as a taxable exchange resulting in
taxable gain or loss to the Certificateholders under the rules discussed above.
In calculating the taxable gain or loss, the amount realized would be equal to
the fair market value of a Certificateholder's pro rata share of the equipment
notes at that time.

Sales of Certificates

   A Certificateholder who sells a Certificate will recognize capital gain or
loss, equal to the difference between the amount realized on the sale, except
for amounts representing accrued interest taxable as interest income, if not
previously included in income, and the Certificateholder's adjusted tax basis
in the Certificate. In general, a Certificateholder's adjusted tax basis in a
certificate will equal the purchase price for the Certificate. Gain or loss
will be long-term capital gain or loss if the Certificate was held for more
than one year, except for amounts attributable to property held by the Trust
for one year or less. Any long-term capital gains are taxable to corporate
taxpayers at ordinary income tax rates and to individual taxpayers at a maximum
rate of 20%. Corporate taxpayers may deduct capital losses only to the extent
of capital gains. Individual taxpayers may deduct capital losses only to the
extent of capital gains plus $3,000 of other income.

Bond Premium

   A Certificateholder generally will be considered to have acquired an
interest in an equipment note at a bond premium if the Certificateholder's tax
basis allocable to the equipment note exceeds the remaining principal amount of
the equipment note allocable to the Certificateholder's Certificate. A
Certificateholder may be able to amortize the bond premium, generally on a
constant yield basis, as a reduction to interest income with corresponding
reductions in the Certificateholder's tax basis in the equipment note. You
should consult your own tax advisors regarding the advisability and
consequences of an election to amortize any bond premium on the equipment
notes.

Original Issue Discount

   The equipment notes will not be issued with original issue discount.

Backup Withholding

   Payments made on Certificates, and proceeds from the sale of Certificates to
or through brokers, may be subject to a "backup" withholding tax of 31% unless
the Certificateholder complies with reporting procedures specified in Treasury
Regulations or is exempt from these requirements. Any withheld amounts will be
allowed as a credit against the Certificateholder' federal income tax and may
entitle the Certificateholder to a refund if the required information is
furnished to the Internal Revenue Service. The Internal Revenue Service may
impose penalties on a Certificateholder who is required to supply information
but does not do so in the proper manner. You should consult your own tax
advisors about your eligibility for, and the procedure for obtaining, exemption
from backup withholding.

                             CERTAIN ILLINOIS TAXES

   The Trustee is a national banking association organized under the laws of
the United States, with its corporate trust office in Illinois. In the opinion
of Vedder, Price, Kaufman & Kammholz, counsel to GATX Rail Corporation, under
currently applicable law, assuming that the Trust is not taxable as a
corporation, but, rather, will be classified as a grantor trust under the Code,
(i) the Trust will not be subject to any tax (including, without limitation,
net or gross income, tangible or intangible property, net worth, capital,
franchise or doing business tax), fee or other governmental charge under the
laws of the State of Illinois or any political subdivision thereof and (ii)
Certificateholders that are not residents of or otherwise subject to tax in
Illinois will not be subject to any tax (including, without limitation, net or

worth, capital, franchise or doing business tax), fee or other governmental
charge under the laws of the State of Illinois or any political subdivision
thereof as a result of purchasing, holding (including receiving payments with
respect to) or selling a Certificate.

   Neither the Trust nor the Certificateholders will be indemnified for any
state or local taxes imposed on them, and the imposition of any such taxes on a
Trust could result in a reduction in the amounts available for distribution to
the Certificateholders of such Trust. In general, should a Certificateholder or
a Trust be subject to any state or local tax which would not be imposed if the
Trustee were located in a different jurisdiction in the United State, the
Trustee will resign and a new Trustee in such other jurisdiction will be
appointed.

                                  UNDERWRITING

   Under the terms of and subject to the conditions contained in the
Underwriting Agreement, Morgan Stanley & Co. Incorporated and Credit Suisse

</TABLE>

   The Underwriting Agreement provides that the obligations of the several
underwriters to pay for and accept delivery of the Certificates are subject to
the approval of certain legal matters by their counsel and to certain other
conditions. The underwriters are obligated to purchase all of the Certificates
if any are purchased thereunder.

   The underwriters initially propose to offer all or part of the Certificates
directly to the public at the public offering price per Certificate designation
set forth on the cover page of this prospectus supplement and may offer a
portion of the Certificates to dealers at a price which represents a concession
not in excess of 0.40% of the principal amount of the Certificates. The
underwriters may allow, and such dealers may reallow, a concession not in
excess of 0.25% of the principal amount of the Certificates to certain other
dealers. After the initial public offering, the public offering prices and such
concessions may be changed from time to time by the underwriters.

   GATX Rail Corporation has agreed to reimburse the underwriters for certain
expenses and to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, as amended.

   GATX Rail Corporation does not intend to apply for listing of the
Certificates on a national securities exchange, but has been advised by the
underwriters that they presently intend to make a market in the Certificates,
as permitted by applicable laws and regulations. No underwriter is obligated,
however, to make a market in the Certificates, and any such market-making may
be discontinued at any time at the sole discretion of such underwriter.
Accordingly, no assurance can be given as to the liquidity of, or trading
markets for, the Certificates.

   In order to facilitate the offering of the Certificates, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Certificates. Specifically, the underwriters may overallot in
connection with the offering, creating a short position in the Certificates for
their own account. In addition, to cover over-allotments or to stabilize the
price of the Certificates, the underwriters may bid for, and purchase,
Certificates in the open market. Finally, the underwriting syndicate may
reclaim selling concessions allowed to

                                      S-39
<PAGE>

an underwriter or a dealer for distributing Certificates in the offering, if
the syndicate repurchases previously distributed Certificates in transactions
to cover syndicate short positions, in stabilization transactions or otherwise.
Any of these activities may stabilize or maintain the market price of the
Certificates above independent market levels. The underwriters are not required
to engage in these activities, and may end any of these activities at any time.

                                 LEGAL OPINIONS

   The validity of the Certificates is being passed upon for GATX Rail
Corporation by Vedder, Price, Kaufman & Kammholz, 222 North LaSalle Street,
Chicago, Illinois 60601, and for the underwriters by Milbank, Tweed, Hadley &
McCloy LLP, One Chase Manhattan Plaza, New York, New York 10005. Both Vedder,
Price, Kaufman & Kammholz and Milbank, Tweed, Hadley & McCloy LLP will rely on
the opinion of the law department of Bank One, NA as to matters relating to the
authorization, execution and delivery of the Certificates under the Basic
Agreement and the Trust Supplement.

PROSPECTUS

                                 $650,000,000
                  General American Transportation Corporation
                           PASS THROUGH CERTIFICATES

                               ----------------

   Up to $650,000,000 aggregate principal amount of Pass Through Certificates
may be offered for sale from time to time pursuant to this Prospectus and
related Prospectus Supplements. Pass Through Certificates may be issued in one
or more series in amounts, at prices and on terms to be determined at the time
of the offering. In respect of each offering of Pass Through Certificates, a
separate General American Transportation Corporation Pass Through Trust for
each series of Pass Through Certificates being offered (each, a "Trust") will
be formed pursuant to the Pass Through Trust Agreement (the "Basic Agreement")
and a supplement thereto (a "Trust Supplement") relating to such Trust between
General American Transportation Corporation ("GATC" or the "Company") and,
unless otherwise specified in the Prospectus Supplement, The First National
Bank of Chicago (the "Pass Through Trustee"), as pass through trustee under
each Trust. Each Pass Through Certificate in a series will represent a
fractional undivided interest in the related Trust and will have no rights,
benefits or interest in respect of any other Trust. The property of each Trust
will consist of equipment notes (the "Equipment Notes") (a) issued, with
recourse to GATC, by GATC to finance all or a portion of the equipment cost
of, or to purchase all or a portion of the outstanding debt with respect to,
certain railcars (the "Equipment Units"), which have been or will be purchased
by GATC (the "Owned Equipment") or (b) issued on a nonrecourse basis by one or
more owner trustees pursuant to separate leveraged lease transactions to
finance or refinance a portion of the equipment cost of Equipment Units which
have been or will be leased to GATC (the "Leased Equipment"). The Prospectus
Supplement relating to each offering of Pass Through Certificates will
describe certain terms of the Pass Through Certificates being offered, the
Trust or Trusts relating thereto, the Equipment Notes to be purchased by such
Trust or Trusts, the Equipment Units relating to such Equipment Notes and the
leveraged lease transactions, if any, relating thereto.

   The Equipment Notes issued in respect of the Leased Equipment (the "Leased
Equipment Notes") will not be direct obligations of, or guaranteed by, GATC,
but the amounts unconditionally payable by GATC for the lease of such Leased
Equipment will be sufficient to pay in full when due all payments required to
be made on such Leased Equipment Notes. The Equipment Notes issued in respect
of the Owned Equipment (the "Owned Equipment Notes") will be direct
obligations of GATC, secured by a security interest in the Owned Equipment.

   Equipment Notes may be issued in respect of Equipment Units in one or more
series, each series having a different interest rate and final maturity date.
A separate Trust will purchase one or more series of the Equipment Notes
issued with respect to each group of Equipment Units (an "Equipment Group").
All of the Equipment Notes held in such Trust will have an interest rate equal
to the interest rate applicable to the Pass Through Certificates issued by
such Trust and maturity dates occurring on or before the final distribution
date applicable to such Pass Through Certificates. The Equipment Notes issued
with respect to each Equipment Group will be secured by a security interest in
such Equipment Group and, in the case of the Leased Equipment, by the lease
relating thereto (each, a "Lease"), including the right to receive rentals
payable in respect of such Equipment Group by GATC.

   Interest paid on the Equipment Notes held in each Trust will be passed
through to the holders of the Pass Through Certificates relating to such Trust
on the dates and at the rate per annum set forth in the Prospectus Supplement
relating to such Pass Through Certificates until the final distribution date
for such Trust. Principal paid on the Equipment Notes held in each Trust will
be passed through to the holders of the Pass Through Certificates relating to
such Trust in scheduled amounts on the dates set forth in the Prospectus
Supplement relating to such Pass Through Certificates until the final
distribution date for such Trust.

   The Pass Through Certificates may be sold through underwriters, dealers or
agents or directly to purchasers. See "Plan of Distribution." The Prospectus
Supplement will set forth the names of any underwriters, dealers or agents
involved in the sale of the Pass Through Certificates in respect of which this
Prospectus is being delivered and any applicable fee, commission or discount
arrangements with them.

                                  THE COMPANY

   GATC is a wholly owned subsidiary of GATX Corporation ("GATX") and is
principally engaged in railcar leasing and management. GATX Terminals
Corporation ("Terminals"), a wholly owned subsidiary of the Company, is engaged
in the operation of public bulk liquid terminals and domestic pipeline systems.
The Company is the largest lessor of railroad tank cars in the United States,
and Terminals is one of the largest independent operators of public bulk liquid
terminals in the world. The principal offices of the Company are located at 500
West Monroe Street, Chicago, Illinois 60661-3676 (telephone: (312) 621-6200).

   The Company leases specialized railcars, primarily tank cars and to a lesser
extent Airslide(R) covered hoppers and plastic pellet cars, under full service
leases. The Company's railcars have a useful life of approximately 30 to 33
years. The average age of the railcars in the Company's fleet is approximately
15 years. The Company's customers typically lease new equipment for a term of
five years or longer, whereas renewals or leases of used cars are typically for
periods ranging from less than a year to seven years with an average lease term
of about three years. Under its full service leases, the Company maintains and
services its railcars, pays ad valorem taxes and provides many ancillary
services.

   Terminals is engaged in the storage, handling and intermodal transfer of
petroleum and chemical commodities at key points in the bulk liquid
distribution chain. Terminals owns and operates terminals in the United States
and the United Kingdom; Terminals also has joint venture interests in
facilities in Europe and the Pacific Rim. All of its terminals are located near
major distribution and transportation points and most are capable of receiving
and shipping bulk liquids by ship, rail, barge and truck. Many of the terminals
are also linked with major interstate pipelines. In addition to storing,
handling and transferring bulk liquids, Terminals also provides blending and
testing services at most of its facilities.

Relationship with GATX

   All of the Company's outstanding common stock is owned by GATX. GATX is also
the parent of American Steamship Company, a shipping company which operates
self-unloading vessels on the Great Lakes, GATX Logistics, Inc., which provides
distribution and logistics support services, warehousing facilities, and
related real estate services throughout North America, and GATX Financial
Services, which through its principal subsidiary, GATX Capital Corporation as
well as its subsidiaries and joint ventures, arranges and services the
financing of equipment and other capital assets on a worldwide basis.

   GATX will not guarantee the Pass Through Certificates and does not guarantee
any other indebtedness of the Company. The Company, in the normal course of
business, pays dividends to GATX to provide for GATX's normal operating
expenses. Additional amounts have been advanced to GATX from time to time for
general corporate purposes, the redemption of GATX preferred stock and the
retirement of debt. In addition, GATX may make advances to subsidiaries of the
Company in the normal course of business. These advances have no fixed maturity
date.

                            FORMATION OF THE TRUSTS

   In respect of each offering of Pass Through Certificates, one or more
Trusts will be formed, and the related Pass Through Certificates will be
issued, pursuant to separate Trust Supplements to be entered into between the
Pass Through Trustee and GATC in accordance with the terms of the Basic
Agreement. All Pass Through Certificates with respect to each Trust will
represent fractional undivided interests in such Trust and the property held
in such Trust, and will have no rights, benefits or interest in respect of any
other Trust or the property held therein. Concurrently with the execution and
delivery of each Trust Supplement, the Pass Through Trustee, on behalf of the
Trust formed thereby, will enter into one or more financing, refinancing,
purchase or participation agreements (each such agreement being herein
referred to as a "Participation Agreement") relating to one or more Equipment
Groups described in the applicable Prospectus Supplement. Pursuant to the
applicable Participation Agreement, the Pass Through Trustee, on behalf of
such Trust, will purchase the Equipment Notes issued with respect to each such
Equipment Group so that all of the Equipment Notes held in such Trust will
have an interest rate equal to the interest rate applicable to the Pass
Through Certificates issued by such Trust. The maturity dates of the Equipment
Notes acquired by each Trust will occur on or before the final distribution
date applicable to the Pass Through Certificates issued with respect to such
Trust. The Pass Through Trustee will distribute the amount of payments of
principal, premium, if any, and interest received by it as holder of the
Equipment Notes to the Certificateholders of the Pass Through Certificates
with respect to the Trust in which such Equipment Notes are held. See
"Description of the Pass Through Certificates" and "Description of the
Equipment Notes."

                                USE OF PROCEEDS

   The Pass Through Certificates offered pursuant to any Prospectus Supplement
will be issued in order to facilitate the financing of all or a portion of the
cost of Owned Equipment described in such Prospectus Supplement or the
financing or refinancing of the debt component of one or more separate
leveraged lease transactions entered into by GATC, as lessee, with respect to
Leased Equipment described therein. The proceeds from the sale of such Pass
Through Certificates will be used by the Pass Through Trustee on behalf of the
applicable Trust or Trusts to purchase, at par, the Owned Equipment Notes
issued by GATC to finance all or a portion of the cost of Owned Equipment
purchased or to be purchased by GATC or the Leased Equipment Notes to be
issued by the respective Owner Trustee or Owner Trustees to finance or
refinance all or a portion of the equipment cost of Leased Equipment.
Simultaneously with the acquisition of such Leased Equipment, the respective
Owner Trustee leased or will lease such Leased Equipment to GATC. As described
in the applicable Prospectus Supplement, a portion of the Equipment Notes
issued with respect to one or more Equipment Groups may be purchased by
investors other than the Pass Through Trustee. Unless otherwise specified in
the applicable Prospectus Supplement, GATC will use the proceeds from each
Owned Equipment Note issued by it and from each separate leveraged lease
transaction for general corporate purposes.

   The Equipment Notes with respect to each Equipment Group will be issued
under a separate Trust Indenture and Security Agreement (each, an "Indenture")
between a bank or trust company as trustee thereunder (each, an "Indenture
Trustee") and (a) with respect to the Owned Equipment, GATC or (b) with
respect to the Leased Equipment, an owner trustee, not in its individual
capacity (except as expressly set forth therein) but solely as trustee (each,
an "Owner Trustee"), of a separate trust for the benefit of one or more
institutional or corporate investors (each, an "Owner Participant"). In the
case of Leased Equipment, each Owner Participant will provide, from sources
other than the Equipment Notes, the balance of the equipment cost of the
related Equipment Group. No Owner Participant, however, will be personally
liable for any amount payable under the related Indenture or the Leased
Equipment Notes issued thereunder. Subject to certain restrictions, each Owner
Participant may transfer its interest in the related Equipment Group.

   Because GATC's obligation to make payments on the Owned Equipment Notes and
to make payments under the Leases relating to the Leased Equipment Notes will
be unconditional, and not affected by the financial performance of the
railcars within the related Equipment Groups, GATC believes that historical
financial information with respect to the Equipment Groups will not be
relevant to purchasers of the Pass Through Certificates.

                  DESCRIPTION OF THE PASS THROUGH CERTIFICATES

   In connection with each offering of Pass Through Certificates, one or more
separate Trusts will be formed and one or more series of Pass Through
Certificates will be issued pursuant to the Basic Agreement and one or more
Trust Supplements to be entered into between GATC and the Pass Through Trustee.
The following summary relates to the Basic Agreement and each of the Trust
Supplements, the Trusts to be formed thereby and the Pass Through Certificates
to be issued by each Trust except to the extent, if any, described in the
applicable Prospectus Supplement. Citations to the relevant sections of the
Basic Agreement appear below in parentheses. The statements under this caption
are a summary and do not purport to be complete. This summary makes use of
terms defined in and is qualified in its entirety by reference to all of the
provisions of the Basic Agreement, the form of which has been filed as an
exhibit to the Registration Statement of which this Prospectus is a part. The
form of the Trust Supplement relating to each series of Pass Through
Certificates and the forms of the Leases, if any, Participation Agreements,
Indentures and Equipment Notes relating thereto will be filed as exhibits to a
report by the Company on Form 8-K, 10-Q, or 10-K, as applicable, to be filed
with the Commission following the offering of such series of Pass Through
Certificates.

General

   The Pass Through Certificates of each Trust will be issued in fully
registered form only. Each Pass Through Certificate will represent a fractional
undivided interest in the separate Trust created by the Trust Supplement
pursuant to which such Pass Through Certificate is issued. The property of each
Trust will include the Equipment Notes held in such Trust, all monies at any
time paid thereon and all monies due and to become due thereunder and funds
from time to time deposited with the Pass Through Trustee in accounts relating
to such Trust. Each Pass Through Certificate will correspond to a pro rata
share of the outstanding principal amount of the Equipment Notes and other
property held in the related Trust and will be issued in denominations of
$1,000 or any integral multiple of $1,000. (Sections 2.01, 2.02 and 3.01)

   Except as otherwise provided in the applicable Trust Supplement, Pass
Through Certificates will be registered in the name of Cede & Co. ("Cede") as
the nominee of The Depository Trust Company ("DTC") and no person acquiring an
interest in Pass Through Certificates (a "Certificate Owner") will be entitled
to receive a certificate representing such person's interest in the related
Trust unless "Definitive Certificates" are issued as described below. Unless
Definitive Certificates are issued, all references to actions by
Certificateholders shall refer to actions taken by DTC upon instructions from
DTC Participants (as defined below), and all references herein to
distributions, notices, reports and statements to Certificateholders shall
refer, as the case may be, to distributions, notices, reports and statements to
DTC or Cede, as the registered holder of the Pass Through Certificates, or to
DTC Participants for distribution to Certificate Owners in accordance with DTC
procedures. See "Description of the Pass Through Certificates--Book-Entry
Registration." (Section 3.09)

   Interest will be passed through to Certificateholders of each Trust at the
rate per annum set forth on the cover page of the applicable Prospectus
Supplement and will be calculated on the basis of a 360-day year of twelve 30-
day months.

   The Pass Through Certificates of each series represent interests only in the
related Trust and all payments and distributions shall be made only from the
related Trust Property. (Section 3.08) The Pass Through Certificates do not
represent an interest in or obligation of GATC, the Pass Through Trustee, the
Owner Trustee, if any, in its individual capacity, the Owner Participant, if
any, or any affiliate of any thereof.

   The Basic Agreement does not and, except as otherwise described in the
applicable Prospectus Supplement, the Indentures will not, include financial
covenants or "event risk" provisions specifically designed to afford
Certificateholders protection in the event of a highly leveraged transaction
affecting GATC. However, the Certificateholders of each series will have the
benefit of a lien on the specific Equipment Group securing the related
Equipment Notes held in the related Trust, as discussed under the caption
"Description of the Equipment Notes--Security."

Book-Entry Registration

   Except as otherwise described in the applicable Prospectus Supplement, Pass
Through Certificates will be subject to the provisions described under this
caption for book-entry registration with DTC.

   DTC. DTC has advised GATC that it is a limited purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the New York
Uniform Commercial Code and a "clearing agency" registered pursuant to Section
17A of the Exchange Act. DTC was created to hold securities for its
participants ("DTC Participants") and to facilitate the clearance and
settlement of securities transactions between DTC Participants through
electronic book-entries, thereby eliminating the need for physical movement of
certificates. DTC Participants include securities brokers and dealers, banks,
trust companies and clearing corporations. Indirect access to the DTC system
also is available to others such as banks, brokers, dealers and trust companies
that clear through or maintain a custodial relationship with a DTC Participant
either directly or indirectly ("Indirect Participants").

   Certificate Owners that are not DTC Participants or Indirect Participants
but desire to purchase, sell or otherwise transfer ownership of, or other
interests in, Pass Through Certificates may do so only through DTC Participants
and Indirect Participants. In addition, Certificate Owners will receive all
distributions of principal, premium, if any, and interest from the Pass Through
Trustee through DTC Participants or Indirect Participants, as the case may be.
Under a book-entry format, Certificate Owners may experience some delay in
their receipt of payments, because such payments will be forwarded by the Pass
Through Trustee to Cede, as nominee for DTC. DTC will forward such payments to
DTC Participants, which thereafter will forward them to Indirect Participants
or Certificate Owners, as the case may be, in accordance with customary
industry practices. The forwarding of such distributions to the Certificate
Owners will be the responsibility of such DTC Participants. The only
"Certificateholder" will be Cede, as nominee of DTC. Certificate Owners will
not be recognized by the Pass Through Trustee as Certificateholders, as such
term is used in the Basic Agreement, and Certificate Owners will be permitted
to exercise the rights of Certificateholders only indirectly through DTC and
DTC Participants.

   Under the rules, regulations and procedures creating and affecting DTC and
its operations (the "Rules"), DTC is required to make book-entry transfers of
Pass Through Certificates among DTC Participants on whose behalf it acts with
respect to the Pass Through Certificates and to receive and transmit
distributions of principal of, premium, if any, and interest on the Pass
Through Certificates. DTC Participants and Indirect Participants with which
Certificate Owners have accounts with respect to the Pass Through Certificates
similarly are required to make book-entry transfers and receive and transmit
such payments on behalf of their respective Certificate Owners. Accordingly,
although Certificate Owners will not possess Pass Through Certificates, the
Rules provide a mechanism by which Certificate Owners will receive payments and
will be able to transfer their interests.

   Because DTC can only act on behalf of DTC Participants, who in turn act on
behalf of Indirect Participants, the ability of a Certificate Owner to pledge
Pass Through Certificates to persons or entities that do not participate in the
DTC system, or to otherwise act with respect to such Pass Through Certificates,
may be limited due to the lack of a physical certificate for such Pass Through
Certificates.

   GATC understands that DTC will take any action permitted to be taken by
Certificateholders only at the direction of one or more DTC Participants to
whose accounts with DTC the Pass Through Certificates are credited.
Additionally, GATC understands that DTC will take such actions with respect to
any specified percentage of the beneficial interest of Certificateholders held
in each Trust only at the direction of and on behalf of DTC Participants whose
holders include undivided interests that satisfy any such percentage. DTC may
take conflicting actions with respect to other undivided interests to the
extent that such actions are taken on behalf of DTC Participants whose holders
include such undivided interests.

   Neither GATC nor the Pass Through Trustee will have any liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interests of the Pass Through Certificates held by Cede, as nominee
for DTC, or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

   The information contained in this section concerning DTC and DTC's book-
entry system has been obtained from sources that the Company believes to be
reliable, but the Company takes no responsibility for the accuracy thereof.

   Definitive Certificates. With respect to each Trust, the related Pass
Through Certificates will be issued in fully registered, certificated form
("Definitive Certificates") to Certificate Owners or their nominees, rather
than to DTC or its nominee, only if (i) GATC advises the Pass Through Trustee
in writing that DTC is no longer willing or able to properly discharge its
responsibilities as depository with respect to such Pass Through Certificates
and the Pass Through Trustee or GATC is unable to locate a qualified successor,
(ii) GATC, at its option, elects to terminate the book-entry system through DTC
or (iii) after the occurrence of an Event of Default (as defined below),
Certificate Owners representing an aggregate percentage interest in such Trust
of not less than a majority advise the Pass Through Trustee through DTC in
writing that the continuation of a book-entry system through DTC (or a
successor thereto) is no longer in the Certificate Owners' best interest.
(Section 3.09)

   Upon the occurrence of any event described in the immediately preceding
paragraph, the Pass Through Trustee will be required to notify all affected
Certificate Owners through DTC Participants of the availability of Definitive
Certificates. Upon surrender by DTC of the certificates representing the Pass
Through Certificates and receipt of instructions for re-registration, the Pass
Through Trustee will reissue the Pass Through Certificates as Definitive
Certificates to Certificate Owners. (Section 3.09)

   Distributions of principal of, premium, if any, and interest on the Pass
Through Certificates will thereafter be made by the Pass Through Trustee in
accordance with the procedures set forth in the Basic Agreement and the
applicable Trust Supplements, directly to holders of Definitive Certificates in
whose names such Definitive Certificates were registered at the close of
business on the applicable record date. Such distributions will be made by
check mailed to the address of each such holder as it appears on the register
maintained with respect to the applicable Trust. The final payment on any Pass
Through Certificate, however, will be made only upon presentation and surrender
of such Pass Through Certificate at the office or agency specified in the
notice of final distribution to Certificateholders. (Section 4.02)

   Definitive Certificates will be freely transferable and exchangeable at the
office of the Pass Through Trustee upon compliance with the requirements set
forth in the Basic Agreement and the applicable Trust Supplements. No service
charge will be imposed for any registration of transfer or exchange, but
payment of a sum sufficient to cover any tax or other governmental charge shall
be required. (Section 3.04)

   Same-Day Settlement and Payment. Settlement for the Pass Through
Certificates will be required to be made in immediately available funds. So
long as the Pass Through Certificates are registered in the name of Cede, all
payments made by GATC to the Indenture Trustees, as assignees of the Owner
Trustees' rights under the Leases, in the case of Leased Equipment Notes, or on
the Owned Equipment Notes, in the case of Owned Equipment Notes, will be in
immediately available funds and will be passed through by the Pass Through
Trustee to DTC in immediately available funds.

   Secondary trading in long-term notes and debentures of corporate issuers is
generally settled in clearinghouse or next-day funds. In contrast, the Pass
Through Certificates will trade in DTC's Same Day Funds Settlement System until
maturity, and secondary market trading activity in the Pass Through
Certificates will therefore be required by DTC to settle in immediately
available funds. No assurance can be given as to the effect, if any, of
settlement in immediately available funds on trading activity in the Pass
Through Certificates.

Payments and Distributions

   Payments received by the Pass Through Trustee of principal of, premium, if
any, and interest on the Equipment Notes held in each Trust will be distributed
by the Pass Through Trustee to the Certificateholders of such Trust on the date
such receipt is confirmed, except in certain cases when some or all of such
Equipment Notes are in default. See "Description of the Pass Through
Certificates--Events of Default and Certain Rights Upon an Event of Default."

                                       7
<PAGE>

   Payments of principal of, and interest on the unpaid principal amount of,
the Equipment Notes held in each Trust will be scheduled to be received by the
Pass Through Trustee on the dates specified in the applicable Prospectus
Supplement (such scheduled payments of principal of, and interest on, the
Equipment Notes are herein referred to as "Scheduled Payments," and the dates
specified therefor in the applicable Prospectus Supplement are herein referred
to as "Regular Distribution Dates"). The Pass Through Trustee of each Trust
will distribute on each Regular Distribution Date to the Certificateholders of
such Trust all Scheduled Payments, the receipt of which is confirmed by the
Pass Through Trustee on such Regular Distribution Date. Each such distribution
of Scheduled Payments will be made by the Pass Through Trustee to the holders
of record of the Pass Through Certificates of such Trust on the fifteenth day
immediately preceding such Regular Distribution Date, subject to certain
exceptions. (Sections 4.01 and 4.02) If a Scheduled Payment is not received by
the Pass Through Trustee on a Regular Distribution Date but is received within
five days thereafter, it will be distributed on the date received to such
holders of record. If it is received after such five-day period, it will be
treated as a Special Payment and distributed as described below.

   Each Certificateholder of each Trust will be entitled to receive a pro rata
share of any distribution in respect of Scheduled Payments of principal and
interest made on the Equipment Notes held in such Trust. Scheduled Payments of
principal on the Equipment Notes held in each Trust will be set forth in the
applicable Prospectus Supplement. After a partial or full prepayment or default
in respect of some or all of such Equipment Notes, a Certificateholder should
refer to the information with respect to the Pool Balance and the Pool Factor
for such Trust reported periodically by the Pass Through Trustee. See
"Description of the Pass Through Certificates--Pool Factors" and "Description
of the Pass Through Certificates--Statements to Certificateholders."

   Payments of principal, premium, if any, and interest received by the Pass
Through Trustee on account of a partial or full prepayment, if any, of the
Equipment Notes held in a Trust, and payments received by the Pass Through
Trustee following a default in respect of the Equipment Notes held in a Trust
(including, in the case of Leased Equipment Notes, payments received by the
Pass Through Trustee on account of their purchase by the related Owner Trustee
or payments received on account of the sale of such Equipment Notes by the Pass
Through Trustee) ("Special Payments") will be distributed on the dates
specified therefor in the applicable Prospectus Supplement (a "Special
Distribution Date"). In general, the Pass Through Trustee will mail notice to
the Certificateholders of record of any Trust not less than 20 days prior to
the Special Distribution Date on which any Special Payment is scheduled to be
distributed by the Pass Through Trustee stating such anticipated Special
Distribution Date. (Section 4.02) Each distribution of a Special Payment, other
than a final distribution, on a Special Distribution Date for any Trust will be
made by the Pass Through Trustee to the holders of record of the Pass Through
Certificates of such Trust on the fifteenth day preceding such Special
Distribution Date. See "Description of the Equipment Notes--Prepayments" and
"Description of the Pass Through Certificates--Events of Default and Certain
Rights Upon an Event of Default."

   The Basic Agreement requires that the Pass Through Trustee establish and
maintain, for each Trust and for the benefit of the Certificateholders of such
Trust, one or more non-interest bearing accounts (the "Certificate Account")
for the deposit of payments representing Scheduled Payments on the Equipment
Notes held in such Trust. (Section 4.01) The Basic Agreement also requires that
the Pass Through Trustee establish and maintain, for each Trust and for the
benefit of the Certificateholders of such Trust, one or more accounts (the
"Special Payments Account") for the deposit of payments representing Special
Payments.

   Pursuant to the terms of the Basic Agreement, the Pass Through Trustee is
required to deposit any Scheduled Payments relating to the applicable Trust
received by it in the Certificate Account of such Trust and to deposit any
Special Payments so received by it in the Special Payments Account of such
Trust. (Section 4.01) All amounts so deposited will be distributed by the Pass
Through Trustee on a Regular Distribution Date or a Special Distribution Date
as appropriate. (Section 4.02)

   At such time, if any, as the Pass Through Certificates of any Trust are
issued in the form of Definitive Certificates and not to Cede, as nominee for
DTC, distributions by the Pass Through Trustee from the Certificate Account or
the Special Payments Account of such Trust on a Regular Distribution Date or a
Special Distribution

                                       8
<PAGE>

Date, as appropriate, will be made by check mailed to each Certificateholder
of such Trust of record on the applicable record date at its address appearing
on the register maintained with respect to such Trust. (Section 4.02) The
final distribution for each Trust, however, will be made only upon
presentation and surrender of the Pass Through Certificates for such Trust at
the office or agency of the Pass Through Trustee specified in the notice given
by the Pass Through Trustee of such final distribution. The Pass Through
Trustee will mail such notice of the final distribution to the
Certificateholders of such Trust, specifying the date set for such final
distribution and the amount of such distribution. (Section 11.01) See
"Description of the Pass Through Certificates--Termination of the Trusts."

   If any Regular Distribution Date or Special Distribution Date is not a
Business Day, distributions scheduled to be made on such Regular Distribution
Date or Special Distribution Date may be made on the next succeeding Business
Day without additional interest. (Section 12.10)

Pool Factors

   Unless there has been a prepayment, or a default in respect of one or more
issues of the Equipment Notes held in a Trust, as described in the applicable
Prospectus Supplement or below in "Description of the Pass Through
Certificates--Events of Default and Certain Rights Upon an Event of Default,"
the Pool Factor for such Trust will decline in proportion to the scheduled
repayments of principal on the Equipment Notes held in such Trust as described
in the applicable Prospectus Supplement. In the event of a partial or full
prepayment or default, the Pool Factor and the Pool Balance of each Trust so
affected will be recomputed after giving effect thereto and notice thereof
will be mailed to Certificateholders of such Trust. Each Trust will have a
separate Pool Factor and Pool Balance.

   Unless otherwise described in the applicable Prospectus Supplement, the
"Pool Balance" for each Trust indicates, as of any date, the aggregate unpaid
principal amount of the Equipment Notes held in such Trust on such date plus
any amounts in respect of principal on such Equipment Notes held by the Pass
Through Trustee and not yet distributed plus the amount of any moneys held in
the related escrow account (other than earnings thereon). The Pool Balance for
each Trust as of any Regular Distribution Date or Special Distribution Date
shall be computed after giving effect to the payment of principal, if any, on
the Equipment Notes held in such Trust and distribution thereof to be made on
that date.

   Unless otherwise described in the applicable Prospectus Supplement, the
"Pool Factor" for each Trust, as of any date, is the quotient (rounded to the
seventh decimal place) computed by dividing (i) the Pool Balance of such
Trust, by (ii) the aggregate original principal amount of the Equipment Notes
held in such Trust. The Pool Factor for each Trust as of any Regular
Distribution Date or Special Distribution Date shall be computed after giving
effect to the payment of principal, if any, on the Equipment Notes held in
such Trust and distribution thereof to be made on that date. The Pool Factor
for each Trust will initially be 1.0000000; thereafter, the Pool Factor for
each Trust will decline as described above to reflect reductions in the Pool
Balance of such Trust. The amount of a Certificateholder's pro rata share of
the Pool Balance of a Trust can be determined by multiplying the original
denomination of the Certificateholder's Pass Through Certificate of such Trust
by the Pool Factor for such Trust as of the applicable Regular Distribution
Date or Special Distribution Date. The Pool Factor and the Pool Balance for
each Trust will be mailed to Certificateholders of record of such Trust on
each Regular Distribution Date and Special Distribution Date.

Statements to Certificateholders

   On each Regular Distribution Date and Special Distribution Date, if any,
the Pass Through Trustee will include with each distribution of a Scheduled
Payment or Special Payment to Certificateholders of record of the related
Trust a statement, giving effect to such distribution to be made on such
Regular Distribution Date or Special Distribution Date, if any, setting forth
the following information (per $1,000 in aggregate principal amount of Pass
Through Certificates for such Trust, as to (i) and (ii) below):

  (i)the amount of such distribution allocable to principal and the amount
   allocable to premium, if any;

  (ii)the amount of such distribution allocable to interest; and

  (iii)the Pool Balance and the Pool Factor for such Trust. (Section 4.03)

                                       9
<PAGE>

   So long as the Pass Through Certificates of any Trust are registered in the
name of Cede, as nominee for DTC, on the applicable record date prior to each
Regular Distribution Date and Special Distribution Date, the Pass Through
Trustee will request from DTC a Securities Position Listing setting forth the
names of all DTC Participants reflected on DTC's books as holding interests in
the Pass Through Certificates of such Trust on such record date. On each
Regular Distribution Date and Special Distribution Date, the Pass Through
Trustee will mail to each such DTC Participant the statement described above,
and will make available additional copies as requested by such DTC Participant,
to be available for forwarding to Certificate Owners. (Section 3.09)

   In addition, after the end of each calendar year, the Pass Through Trustee
will prepare for each Certificateholder of record of each Trust at any time
during the preceding calendar year a report containing the sum of the amounts
determined pursuant to clauses (i) and (ii) above with respect to the Trust for
such calendar year or, in the event such person was a Certificateholder of
record during a portion of such calendar year, for the applicable portion of
such calendar year, and such other items as are readily available to the Pass
Through Trustee and which a Certificateholder shall reasonably request as
necessary for the purpose of such Certificateholder's preparation of its
federal income tax returns. (Section 4.03) Such report and such other items
shall be prepared on the basis of information supplied to the Pass Through
Trustee by the DTC Participants, and shall be delivered by the Pass Through
Trustee to such DTC Participants to be available for forwarding by such DTC
Participants to Certificate Owners in the manner described above.

   At such time, if any, as the Pass Through Certificates of a Trust are issued
in the form of Definitive Certificates, the Pass Through Trustee will prepare
and deliver the information described above to each Certificateholder of record
of such Trust as the name and period of record ownership of such
Certificateholder appears on the records of the Registrar of the Pass Through
Certificates.

Voting of Equipment Notes

   The Pass Through Trustee, as holder of the Equipment Notes held in each
Trust, has the right to vote and give consents and waivers in respect of such
Equipment Notes under the applicable Indenture. The Basic Agreement sets forth
the circumstances in which the Pass Through Trustee shall direct any action or
cast any vote as the holder of the Equipment Notes held in the applicable Trust
at its own discretion and the circumstances in which the Pass Through Trustee
shall seek instructions from the Certificateholders of such Trust. Prior to an
Event of Default with respect to any Trust, the principal amount of the
Equipment Notes held in such Trust directing any action or being voted for or
against any proposal shall be in proportion to the principal amount of Pass
Through Certificates held by the Certificateholders of such Trust taking the
corresponding position. (Sections 6.01 and 10.01)

Events of Default and Certain Rights Upon an Event of Default

   The Basic Agreement defines an event of default with respect to a Trust (an
"Event of Default") as the occurrence and continuance of an event of default
under one or more of the related Indentures (an "Indenture Event of Default").
The Indenture Events of Default will be described in the applicable Prospectus
Supplement and, in the case of Leased Equipment Notes, will include events of
default under the related Lease. Because the Equipment Notes issued under an
Indenture may be held in more than one Trust, a continuing Indenture Event of
Default under such Indenture would result in an Event of Default with respect
to each such Trust. There will be, however, no cross-default provisions in the
Indentures and events resulting in an Indenture Event of Default under any
particular Indenture (or a default under any other indebtedness of the Company)
will not necessarily result in an Indenture Event of Default occurring under
any other Indenture. If an Indenture Event of Default occurs in fewer than all
of the Indentures related to a Trust, the Equipment Notes issued pursuant to
the related Indentures with respect to which an Indenture Event of Default has
not occurred will continue to be held in such Trust and payments of principal
and interest on such Equipment Notes will continue to be distributed to the
holders of the Pass Through Certificates of such Trust as originally scheduled.

                                       10
<PAGE>

   In the case of Leased Equipment, the Owner Trustee and the Owner Participant
under each Indenture will each have the right under certain circumstances to
cure an Indenture Event of Default that results from the occurrence of a Lease
Event of Default under the related Lease. If the Owner Trustee or the Owner
Participant chooses to exercise such cure right, the Indenture Event of Default
and consequently the Event of Default with respect to the related Trust or
Trusts will be deemed to be cured.

   The Basic Agreement provides that, as long as an Indenture Event of Default
under any Indenture relating to Equipment Notes held in a Trust shall have
occurred and be continuing, the Pass Through Trustee of such Trust may vote all
of the Equipment Notes issued under such Indenture that are held in such Trust,
and upon the direction of the holders of Pass Through Certificates evidencing
fractional undivided interests aggregating not less than a majority in interest
of such Trust, shall vote not less than a corresponding majority of such
Equipment Notes in favor of directing the related Indenture Trustee to declare
the unpaid principal amount of all Equipment Notes issued under such Indenture
and any accrued and unpaid interest thereon to be due and payable. The Basic
Agreement also provides that, if an Indenture Event of Default under any
Indenture relating to Equipment Notes held in a Trust shall have occurred and
be continuing, the Pass Through Trustee of such Trust may, and upon the
direction of the holders of Pass Through Certificates evidencing fractional
undivided interests aggregating not less than a majority in interest of such
Trust shall, subject to certain conditions, vote all of the Equipment Notes
issued under such Indenture that are held in such Trust in favor of directing
the related Indenture Trustee as to the time, method and place of conducting
any proceeding for any remedy available to such Indenture Trustee or of
exercising any trust or power conferred on such Indenture Trustee under such
Indenture. (Sections 6.01 and 6.04)

   The ability of the holders of the Pass Through Certificates issued with
respect to any one Trust to cause the Indenture Trustee with respect to any
Equipment Notes held in such Trust to accelerate the payment on such Equipment
Notes under the related Indenture or to direct the exercise of remedies by such
Indenture Trustee under the related Indenture will depend, in part, upon the
percentage of the aggregate principal amount of all Equipment Notes outstanding
under such Indenture that are represented by the Equipment Notes outstanding
under such Indenture and held in such Trust. Each Trust will hold Equipment
Notes with different terms from those of the Equipment Notes held in the other
Trusts and therefore the Certificateholders of a Trust may have divergent or
conflicting interests from those of the Certificateholders of the other Trusts
holding Equipment Notes relating to the same Equipment Group. In addition, so
long as the same institution acts as Pass Through Trustee of each Trust, in the
absence of instructions from the Certificateholders of any such Trust, the Pass
Through Trustee for such Trust could for the same reason be faced with a
potential conflict of interest upon an Indenture Event of Default. In such
event, the Pass Through Trustee has indicated that it would resign as trustee
of one or all such Trusts, and a successor trustee for one or all of such
Trusts would be appointed in accordance with the terms of the Basic Agreement.

   As an additional remedy, if an Indenture Event of Default shall have
occurred and be continuing, the Basic Agreement provides that the Pass Through
Trustee of a Trust holding Equipment Notes issued under such Indenture may, and
upon the direction of the holders of Pass Through Certificates evidencing
fractional undivided interests aggregating not less than a majority in interest
of such Trust shall, sell all or part of such Equipment Notes for cash to any
person. (Sections 6.01 and 6.02) Any proceeds received by the Pass Through
Trustee upon any such sale shall be deposited in the Special Payments Account
for such Trust and shall be distributed to the Certificateholders of such Trust
on a Special Distribution Date. (Sections 4.01 and 4.02) The market for
Equipment Notes in default may be very limited and there can be no assurance
that they could be sold for a reasonable price. Furthermore, so long as the
same institution acts as Trustee of each Trust, it may be faced with a conflict
in deciding from which Trust to sell Equipment Notes to available buyers. If
the Pass Through Trustee sells any such Equipment Notes with respect to which
an Indenture Event of Default exists for less than their outstanding principal
amount, the Certificateholders of such Trust will receive a smaller amount of
principal distributions than anticipated and will not have any claim for the
shortfall against GATC, the related Owner Trustee or the related Owner
Participant, in the case of any Leased Equipment, or the Pass Through Trustee.
Furthermore, neither the Pass Through Trustee nor the Certificateholders of
such Trust could take any

                                       11
<PAGE>

action with respect to any remaining Equipment Notes held in such Trust so
long as no Indenture Event of Default existed with respect thereto.

   Any amount distributed to the Pass Through Trustee of any Trust by the
Indenture Trustee under any Indenture on account of the Equipment Notes held
in such Trust following an Indenture Event of Default under such Indenture
shall be deposited in the Special Payments Account for such Trust and shall be
distributed to the Certificateholders of such Trust on a Special Distribution
Date. In addition, if, following an Indenture Event of Default under any
Indenture relating to Leased Equipment, the related Owner Trustee exercises
its option, if any, to purchase the outstanding Leased Equipment Notes issued
under such Indenture as described in the related Prospectus Supplement, the
price paid by such Owner Trustee to the Pass Through Trustee of any Trust for
the Leased Equipment Notes issued under such Indenture and held in such Trust
shall be deposited in the Special Payments Account for such Trust and shall be
distributed to the Certificateholders of such Trust on a Special Distribution
Date. (Sections 4.01 and 4.02)

   Any funds held by the Pass Through Trustee in the Special Payments Account
for a Trust representing either payments received with respect to any
Equipment Notes held in such Trust following an Indenture Event of Default or
proceeds from the sale by the Pass Through Trustee of any such Equipment
Notes, shall, to the extent practicable, be invested and reinvested by the
Pass Through Trustee in Permitted Government Investments pending the
distribution of such funds on a Special Distribution Date. Permitted
Government Investments are defined as being obligations of the United States
and agencies thereof maturing in not more than 60 days or such lesser time as
is required for the distribution of any such funds on a Special Distribution
Date. (Sections 4.01 and 4.04)

   The Basic Agreement provides that the Pass Through Trustee of each Trust
shall, within 90 days after the occurrence of a default (as defined below) in
respect of such Trust, give to the Certificateholders of such Trust notice,
transmitted by mail, of all uncured or unwaived defaults with respect to such
Trust known to it; provided that, except in the case of default in the payment
of principal of, premium, if any, or interest on any of the Equipment Notes
held in such Trust, the Pass Through Trustee shall be protected in withholding
such notice if it in good faith determines that the withholding of such notice
is in the interest of such Certificateholders. The term "default," for the
purpose of the provision described in this paragraph only, shall mean the
occurrence of any Event of Default with respect to a Trust as specified above,
except that in determining whether any such Event of Default has occurred any
grace period or notice in connection therewith shall be disregarded.
(Section 7.02)

   The Basic Agreement contains a provision entitling the Pass Through Trustee
of each Trust, subject to the duty of the Pass Through Trustee during a
default to act with the required standard of care, to be indemnified by the
holders of the Pass Through Certificates of such Trust before proceeding to
exercise any right or power under the Basic Agreement at the request of such
Certificateholders. (Section 7.03)

   In certain cases, the holders of Pass Through Certificates of a Trust
evidencing fractional undivided interests aggregating not less than a majority
in interest of such Trust may on behalf of the holders of all Pass Through
Certificates of such Trust waive any past default or Event of Default with
respect to such Trust and thereby annul any direction given by the Pass
Through Trustee on behalf of such holders to the related Indenture Trustee
with respect thereto, except (i) a default in the deposit of any Scheduled
Payment or Special Payment or in the distribution of any such payment, (ii) a
default in payment of the principal of, premium, if any, or interest on any of
the Equipment Notes held in such Trust, and (iii) a default in respect of any
covenant or provision of the Basic Agreement or the related Trust Supplement
that cannot be modified or amended without the consent of each
Certificateholder of such Trust affected thereby. (Section 6.05) Each
Indenture will provide that, with certain exceptions, the holders of a
majority in aggregate unpaid principal amount of the Equipment Notes issued
thereunder may on behalf of all such holders waive any past default or
Indenture Event of Default thereunder. In the event of a waiver with respect
to a Trust as described above, the principal amount of the Equipment Notes
issued under the related Indenture held in such Trust shall be counted as
waived in the determination of the majority in aggregate unpaid principal
amount of Equipment Notes required to waive a default or an Indenture

                                      12
<PAGE>

Event of Default under such Indenture. Therefore, if the Certificateholders of
a Trust waive a past default or Event of Default such that the principal
amount of the Equipment Notes held in such Trust constitutes the required
majority in aggregate unpaid principal amount under the applicable Indenture,
such past default or Indenture Event of Default under such Indenture shall be
waived. For a discussion of waivers of Indenture Events of Default under the
Indentures, see "Description of the Equipment Notes--Indenture Events of
Default and Remedies."

Modifications of the Basic Agreement

   The Basic Agreement contains provisions permitting GATC and the Pass
Through Trustee of each Trust to enter into supplemental trust agreements,
without the consent of the holders of any of the Pass Through Certificates of
such Trust, (i) to evidence the succession of another corporation to GATC and
the assumption by such corporation of GATC's obligations under the Basic
Agreement and the applicable Trust Supplement, (ii) to add to the covenants of
GATC for the benefit of the holders of such Pass Through Certificates, (iii)
to cure any ambiguity, to correct any manifest error or to correct or
supplement any defective or inconsistent provision of such Basic Agreement,
the applicable Trust Supplement or any supplemental trust agreement, or to
make any other provisions with respect to matters or questions arising
thereunder, provided such action shall not adversely affect the interest of
the holders of such Pass Through Certificates, (iv) to evidence and provide
for a successor Trustee for some or all of the Trusts, or (v) to make any
other amendments or modifications which shall only apply to Pass Through
Certificates of one or more series to be issued thereafter. (Section 9.01)

   The Basic Agreement also contains provisions permitting GATC and the Pass
Through Trustee of each Trust, with the consent of the Certificateholders of
such Trust evidencing fractional undivided interests aggregating not less than
a majority in interest of such Trust, to execute supplemental trust agreements
adding any provisions to or changing or eliminating any of the provisions of
the Basic Agreement, to the extent relating to such Trust, and the applicable
Trust Supplement, or modifying the rights of such Certificateholders, except
that no such supplemental trust agreement may, without the consent of the
holder of each such Pass Through Certificate so affected, (a) reduce in any
manner the amount of, or delay the timing of, any receipt by the Pass Through
Trustee of payments on the Equipment Notes held in such Trust, or
distributions in respect of any Pass Through Certificate of such Trust, or
make distributions payable in coin or currency other than that provided for in
such Pass Through Certificates, or impair the right of any Certificateholder
of such Trust to institute suit for the enforcement of any such payment when
due, (b) permit the disposition of any Equipment Note held in such Trust,
except as provided in the Basic Agreement or the applicable Trust Supplement,
or (c) reduce the percentage of the aggregate fractional undivided interests
of the Trust provided for in the Basic Agreement or the applicable Trust
Supplement, the consent of the holders of which is required for any such
supplemental trust agreement or for any waiver provided for in the Basic
Agreement or such Trust Supplement. (Section 9.02)

Modification and Consents and Waivers Under the Indentures and Related
Agreements

   In the event that the Pass Through Trustee, as the holder of any Equipment
Notes held in a Trust, receives a request for its consent to any amendment,
modification or waiver under the Indenture, Lease, if any, or other document
relating to such Equipment Notes, which requires the consent of the
Certificateholders of such Trust, the Pass Through Trustee shall mail a notice
of such proposed amendment, modification or waiver to each Certificateholder
of such Trust as of the date of such notice. The Pass Through Trustee shall
request instructions from the Certificateholders of such Trust as to whether
or not to consent to such amendment, modification or waiver. The Pass Through
Trustee shall vote or consent with respect to such Equipment Notes in such
Trust in the same proportion as the Pass Through Certificates of such Trust
were actually voted by the holders thereof by a certain date. Notwithstanding
the foregoing, if an Event of Default in respect of such Trust shall have
occurred and be continuing, the Pass Through Trustee, subject to the voting
instructions referred to under "Description of the Pass Through Certificates--
Events of Default and Certain Rights Upon an Event of Default," may in its own
discretion consent to such amendment, modification or waiver, and may so
notify the Indenture Trustee to which such consent relates. (Section 10.01)

                                      13
<PAGE>

Termination of the Trusts

   The obligations of GATC and the Pass Through Trustee with respect to a Trust
will terminate upon the distribution to Certificateholders of such Trust of all
amounts required to be distributed to them pursuant to the Basic Agreement and
the applicable Trust Supplement and the disposition of all property held in
such Trust. The Pass Through Trustee will mail to each Certificateholder of
record of such Trust notice of the termination of such Trust, the amount of the
proposed final payment and the proposed date for the distribution of such final
payment for such Trust. The final distribution to any Certificateholder of such
Trust will be made only upon surrender of such Certificateholder's Pass Through
Certificates at the office or agency of the Pass Through Trustee specified in
such notice of termination. (Section 11.01)

Delayed Purchase

   In the event that, on the date of issuance of any Pass Through Certificates,
all of the proceeds from the sale of such Pass Through Certificates are not
used to purchase the Equipment Notes contemplated to be held in the related
Trust, such Equipment Notes may be purchased by the Pass Through Trustee at any
time on or prior to the date specified in the applicable Prospectus Supplement.
In such event, the Pass Through Trustee will hold the proceeds from the sale of
such Pass Through Certificates not used to purchase Equipment Notes in an
escrow account pending the purchase of the Equipment Notes not so purchased.
Such proceeds will be invested in Specified Investments at the direction and
risk of, and for the account of, GATC. Earnings on Specified Investments in the
escrow account for each Trust will be paid to GATC periodically, and GATC will
be responsible for any losses realized on such Specified Investments. (Section
2.02)

   On the Regular Distribution Date occurring after the issuance of such Pass
Through Certificates, GATC will pay to the Pass Through Trustee an amount equal
to the interest that would have accrued on any Equipment Notes which are
purchased after the date of the issuance of such Pass Through Certificates from
the date of the issuance of such Pass Through Certificates to, but excluding,
the date of the purchase of such Equipment Notes by the Pass Through Trustee.
(Section 2.02)

   To the extent that Equipment Notes are not purchased by the Pass Through
Trustee on or prior to the date specified in the applicable Prospectus
Supplement, the unexpended proceeds from the sale of such Pass Through
Certificates, together with interest thereon at the rate applicable to such
Pass Through Certificates, will be distributed to the holders of such Pass
Through Certificates as a Special Payment.

Merger, Consolidation and Transfer of Assets

   GATC will be prohibited from consolidating with or merging into any other
corporation or transferring substantially all of its assets as an entirety to
any other corporation unless any successor or transferee corporation shall be a
corporation organized and existing under the laws of the United States or any
state or the District of Columbia and shall expressly assume all of the
obligations of GATC contained in the Basic Agreement, and, in the case of
Leased Equipment Notes held in a Trust, both immediately prior to and after
giving effect to such consolidation, merger or transfer, no Lease Event of
Default shall have occurred and be continuing. (Section 5.02)

The Pass Through Trustee

   Unless otherwise specified in the applicable Prospectus Supplement, The
First National Bank of Chicago will be the Pass Through Trustee for each of the
Trusts. The Pass Through Trustee and any of its affiliates may hold Pass
Through Certificates in their own names. (Section 7.05) With certain
exceptions, the Pass Through Trustee makes no representations as to the
validity or sufficiency of the Basic Agreement, the Trust Supplements, the Pass
Through Certificates, the Equipment Notes, the Indentures, the Leases, if any,
or other related documents. (Section 7.04) Unless otherwise specified in a
Prospectus Supplement, The First National Bank of Chicago will also be the
Indenture Trustee of the Indentures under which the Equipment Notes are issued.
The Company maintains banking relationships in the ordinary course of business
with The First National Bank of Chicago.

                                       14

   The Pass Through Trustee may resign with respect to any or all of the Trusts
at any time, in which event GATC will be obligated to appoint a successor
trustee. If the Pass Through Trustee ceases to be eligible to continue as
Trustee with respect to a Trust or becomes incapable of acting as Trustee or
becomes insolvent, GATC may remove such Trustee. In addition, any holder of
Pass Through Certificates of such Trust for at least six months may in such
circumstances, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the removal of such Trustee and the
appointment of a successor trustee. Any resignation or removal of the Pass
Through Trustee with respect to a Trust and appointment of the successor
trustee for such Trust does not become effective until acceptance of the
appointment by the successor trustee. (Section 7.09) Pursuant to such
resignation and successor trustee provisions, it is possible that a different
trustee could be appointed to act as the successor trustee with respect to each
Trust. All references in this Prospectus to the Pass Through Trustee are to the
trustee acting in such capacity under each of the Trusts and should be read to
take into account the possibility that each of the Trusts could have a
different successor trustee in the event of such a resignation or removal.

   The Basic Agreement provides that GATC will pay the Pass Through Trustee's
fees and expenses and will indemnify the Pass Through Trustee in accordance
with the Participation Agreement with respect to certain taxes. To the extent
not indemnified by GATC with respect to such taxes, the Pass Through Trustee
may be entitled to be reimbursed by the applicable Trust. (Section 7.07)

                       DESCRIPTION OF THE EQUIPMENT NOTES

   The statements under this caption are summaries and do not purport to be
complete. Except as otherwise indicated below or as described in the applicable
Prospectus Supplement, the following summaries will apply to the Equipment
Notes, the Indenture, the Lease, if any, and the Participation Agreement
relating to each Equipment Group. Additional provisions with respect to the
Equipment Notes, the Indentures, the Leases, if any, and the Participation
Agreements relating to any particular Equipment Group will be described in the
applicable Prospectus Supplement.

General

   Each Equipment Note issued under the same Indenture will relate to a single
Equipment Group. The Equipment Notes with respect to each Equipment Group will
be issued under a separate Indenture between the related Indenture Trustee and
GATC (in the case of Owned Equipment Notes) or the related Indenture Trustee
and the Owner Trustee of a trust for the benefit of the Owner Participant which
is the beneficial owner of such Equipment Group (in the case of Leased
Equipment Notes).

   GATC's obligations under each Indenture relating to Owned Equipment and
under the related Owned Equipment Notes will be direct obligations of GATC,
secured by a security interest in such Owned Equipment. The Leased Equipment
Notes will be nonrecourse obligations of the related Owner Trustee. Except in
certain circumstances involving GATC's purchase of Leased Equipment and the
assumption of the Leased Equipment Notes related thereto, the Leased Equipment
Notes will not be direct obligations of, or guaranteed by, GATC; however, GATC
will be obligated to make or cause to be made rental and other payments to the
related Owner Trustee under the Lease of the related Equipment Group in amounts
that will be at least sufficient to pay when due all payments required to be
made on the Leased Equipment Notes issued with respect to such Equipment Group.
GATC's rental obligations under each Lease will be general obligations of GATC.

Principal and Interest Payments

   Interest paid on the Equipment Notes held in each Trust will be passed
through to the Certificateholders of such Trust on the dates and at the rate
per annum set forth in the applicable Prospectus Supplement until the final
distribution date for such Trust. Principal paid on the Equipment Notes held in
each Trust will be passed through to the Certificateholders of such Trust in
scheduled amounts on the dates set forth in the applicable Prospectus
Supplement until the final distribution date for such Trust.


                                       15
<PAGE>

   If any date scheduled for any payment of principal of, premium, if any, or
interest on the Equipment Notes is not a Business Day, such payment may be made
on the next succeeding Business Day without any additional interest.

Prepayments

   The applicable Prospectus Supplement will describe the circumstances,
whether voluntary or involuntary, under which the related Equipment Notes may
be prepaid or purchased, the premium (if any) related to certain prepayments or
purchases and other terms applying to prepayments or purchases of such
Equipment Notes.

Security

   The Leased Equipment Notes issued with respect to an Equipment Group will be
secured by (i) an assignment by the related Owner Trustee to the related
Indenture Trustee of such Owner Trustee's rights (except for certain limited
rights described in the Prospectus Supplement) under the Lease with respect to
such Equipment Group, including the right to receive payments of rent
thereunder and (ii) a perfected security interest to such Indenture Trustee in
such Equipment Group, subject to the rights of GATC under such Lease. Unless
and until an Indenture Event of Default with respect to an Equipment Group has
occurred and is continuing, the Indenture Trustee may not exercise the rights
of the Owner Trustee under the related Lease, except the right to receive
payments of rent due thereunder.

   The Owned Equipment Notes issued with respect to an Equipment Group will be
secured by a perfected security interest from GATC to the related Indenture
Trustee in such Equipment Group.

   The Equipment Notes issued under different Indentures will not be cross-
collateralized and consequently the Equipment Notes issued in respect of any
one Equipment Group will not be secured by any other Equipment Group or, in the
case of Leased Equipment Notes, the Lease related to any other Equipment Group.

   GATC will be required to file each Indenture, any indenture supplement, each
Lease, if any, and any lease supplement with respect to each Equipment Group
under the Interstate Commerce Act (or successor law) and will be further
required to deposit such documents with the Registrar General of Canada under
the Railway Act of Canada and to publish notice of such deposit in accordance
with such Act. The filing under the Interstate Commerce Act (or successor law)
will give the Indenture Trustee a perfected security interest in each Equipment
Unit in such Equipment Group whenever it is located in the United States and in
the Lease, if any. Such deposit and publication in Canada will be done in order
to protect the lien of the Indenture Trustee in and to the Lease, if any, and
the Equipment Units created by the Indenture in Canada or any province or
territory thereof, to the extent provided for in the Railway Act of Canada.

   Each Equipment Unit may be operated by GATC or, subject to certain
limitations, under sublease or interchange arrangements in the United States,
Canada or Mexico. The extent to which the Indenture Trustee's security interest
would be recognized in an Equipment Unit located in countries other than the
United States is uncertain.

   Funds, if any, held from time to time by the Indenture Trustee with respect
to any Equipment Units, including funds held as the result of the loss or
destruction of such Equipment Units or termination of the Lease, if any,
relating thereto, will be invested and reinvested by such Indenture Trustee, at
the direction of GATC (except in the case of a Lease Event of Default under the
applicable Lease, if any), in Specified Investments. GATC will pay the amount
of any loss resulting from any such investment directed by it.

   GATC will be obligated, at its cost and expense, to maintain, repair and
keep each Equipment Unit in accordance with prudent industry maintenance
practices and in compliance in all material respects with all laws and
regulations.


                                       16
<PAGE>

Limitation of Liability

   The Owned Equipment Notes will be direct obligations of GATC. Except in
certain circumstances involving GATC's purchase of Leased Equipment and the
assumption of the Leased Equipment Notes related thereto, the Leased Equipment
Notes will not be direct obligations of, or guaranteed by, GATC or the Owner
Trustees. None of the Owner Trustees, the Owner Participants or the Indenture
Trustees, or any affiliates thereof, shall be personally liable to any holder
of a Leased Equipment Note or, in the case of the Owner Trustees and the Owner
Participants, to the Indenture Trustees for any amounts payable under the
Leased Equipment Notes or, except as provided in each Indenture, for any
liability under such Indenture. Except in the circumstances described above,
all payments of principal of, premium, if any, and interest on Leased Equipment
Notes issued with respect to any Equipment Group (other than payments made in
connection with an optional prepayment or purchase by the related Owner
Trustee) will be made only from the assets subject to the lien of the Indenture
with respect to such Equipment Group or the income and proceeds received by the
related Indenture Trustee therefrom (including rent payable by GATC under the
Lease with respect to such Equipment Group).

   Except as otherwise provided in the Indentures, each Owner Trustee in its
individual capacity shall not be answerable or accountable under the Indentures
or under the Leased Equipment Notes under any circumstances except for its own
wilful misconduct or gross negligence. None of the Owner Participants will have
any duty or responsibility under any of the Indentures or the Leased Equipment
Notes to the Indenture Trustees or to any holder of any Leased Equipment Note.

Indenture Events of Default and Remedies

   The applicable Prospectus Supplement will describe the Indenture Events of
Default under the related Indentures, the remedies that the Indenture Trustee
may exercise with respect to the related Equipment Group, either at its own
initiative or upon instruction from holders of the related Equipment Notes, and
other provisions relating to the occurrence of an Indenture Event of Default
and the exercise of remedies. There will be no cross-default provisions in the
Indentures and events resulting in an Indenture Event of Default under any
particular Indenture (or a default under any other indebtedness of the Company)
will not necessarily result in an Indenture Event of Default under any other
Indenture.

   In the case of Leased Equipment Notes, in the event of the bankruptcy of an
Owner Participant, it is possible that, notwithstanding that the related
Equipment Group is owned by an Owner Trustee in trust, such Equipment Group and
the Lease and the Leased Equipment Notes related thereto might become part of
the bankruptcy proceeding. In such event, payments on such Leased Equipment
Notes might be interrupted and the ability of the Indenture Trustee to exercise
its remedies under the applicable Indenture might be restricted, although the
Indenture Trustee would retain its status as a secured creditor in respect of
such Lease and the related Equipment Group. In addition, in the event of an
Owner Participant bankruptcy, the estate might seek court approval to reject
the related Lease as an executory contract. Such a Lease rejection, if
successful, would leave the Indenture Trustee as a secured creditor in respect
of the related Equipment Group with a claim for damages against the estate.

The Leases

   In the case of Leased Equipment Notes, the following provisions will be
applicable unless otherwise disclosed in the Prospectus Supplement.

   Term and Rentals. In the case of Leased Equipment, each Equipment Group will
be leased separately by the related Owner Trustee to GATC for a term commencing
on the delivery date thereof to such Owner Trustee and expiring on a date not
earlier than the latest maturity date of the Leased Equipment Notes issued with
respect to such Equipment Group unless previously terminated as permitted by
the related Lease. The basic rental payments by GATC under each Lease will be
payable on the dates specified in the applicable Prospectus Supplement, and
will be assigned by the Owner Trustee under the related Indenture to provide
the funds

                                       17
<PAGE>

necessary to make payments of principal and interest due from such Owner
Trustee on the Leased Equipment Notes issued under such Indenture. Although in
certain cases the basic rental payments under the Leases may be adjusted,
under no circumstances will rental payments be less than the scheduled
payments of principal and interest on the Leased Equipment Notes issued under
the Indenture relating to such Lease. The balance of any basic rental payments
under each Lease, after payment of the scheduled principal and interest on the
Leased Equipment Notes issued under the Indenture relating to such Lease, will
be paid over to the related Owner Trustee. GATC's obligation to pay rent and
to cause other payments to be made under each Lease will be a general
obligation of GATC.

   Net Lease. GATC's obligations in respect of each Equipment Group leased by
an Owner Trustee will be those of a lessee under a "net lease." Accordingly,
GATC will be obligated, at its cost and expense, to maintain, repair and keep
each Equipment Unit in any such Equipment Group in accordance with prudent
industry maintenance practices and in compliance in all material respects with
all laws and regulations and consistent with maintenance practices used by
GATC in respect of equipment owned or leased by GATC similar in type to such
Equipment Unit. Subject to certain exceptions, GATC will, at its expense, make
all alterations, replacements or modifications required to be made by the
Association of American Railroads, the United States Department of
Transportation, or any other United States, state or local governmental
agency. GATC reserves the right to contest the validity or applicability of
any required alterations, replacements or modifications. GATC shall have the
right to make alterations, modifications and improvements with respect to each
Equipment Unit in any such Equipment Group, provided that no such alteration,
modification or improvement shall materially diminish the fair market value,
utility or remaining economic useful life of such Unit.

   Insurance. Unless waived or otherwise excused by the terms of any Lease,
GATC will be required to procure from reputable insurance companies, property
damage and public liability insurance, and, subject to certain limited
exceptions, maintain such insurance in such amounts and for such risks and
with such insurance companies and subject to such deductibles and self
insurance no less comprehensive in amounts and against risks customarily
insured against by GATC in respect of equipment owned or leased by it similar
in type to the related Equipment Units and consistent with prudent industry
standards for companies engaged in full service leasing of railcars, if any.

   Lease Events of Default; Remedies. The applicable Prospectus Supplement
will describe the Lease Events of Default under the related Lease, the
remedies that the Owner Trustee, or Indenture Trustee as assignee of the Owner
Trustee, may exercise with respect to an Equipment Group, and other provisions
relating to the occurrence of a Lease Event of Default and the exercise of
remedies.

   Lease Events of Default under each Lease will include, among other things,
(a) failure by GATC to make rental payments under the Lease, (b) failure to
maintain insurance as required by the Lease, (c) use of the Equipment Group in
contravention of the Lease, (d) breach of any representation or warranty made
by GATC in the Lease or in the related Participation Agreement and (e) the
occurrence of certain events of bankruptcy, reorganization or insolvency of
GATC. Upon the occurrence of a Lease Event of Default under any Lease, the
related Indenture Trustee, as assignee of the related Owner Trustee's rights
under such Lease, will be entitled to repossess the Equipment Units and use or
sell such Equipment Units free and clear of GATC's rights therein.

   If GATC were to become a debtor in a bankruptcy or reorganization case
under the Bankruptcy Code, GATC or its bankruptcy trustee could reject any or
all Leases to which it is a party. In such event, there could be no assurance
that the amount of any claim for damages under such Leases that would be
allowed in such bankruptcy case would be in an amount sufficient to provide
for the repayment of the related Leased Equipment Notes. In any case,
rejection of a Lease by GATC or its bankruptcy trustee would not deprive the
related Indenture Trustee of its security interest in the related Equipment
Group.

   GATC is not a railroad, and the protections against the automatic stay in
bankruptcy under Section 1168 of the Bankruptcy Code which are granted to
lessors, conditional vendors and purchase money financiers of rolling stock to
a common carrier by railroad will not be available to an Indenture Trustee
upon the occurrence of a Lease Event of Default.

                                      18
<PAGE>

The Participation Agreements

   GATC will be required to indemnify each Indenture Trustee and the Pass
Through Trustee and, in the case of Leased Equipment, each Owner Participant
and Owner Trustee for certain losses and claims and for certain other matters.
Each Owner Participant will be required to discharge certain liens or claims on
or against the assets subject to the lien of the related Indenture that arise
out of any act of or failure to act by or claim against such Owner Participant.
Subject to certain restrictions, each Owner Participant may transfer its
interest in the related Equipment Group.

                              ERISA CONSIDERATIONS

   Unless otherwise indicated in the applicable Prospectus Supplement, Pass
Through Certificates may be purchased by an employee benefit plan (a "Plan")
subject to the Employee Retirement Income Security Act of 1974, as amended
("ERISA"). A fiduciary of a Plan must determine that the purchase of a Pass
Through Certificate is consistent with its fiduciary duties under ERISA and
does not result in a non-exempt prohibited transaction as defined in Section
406 of ERISA or Section 4975 of the Code. Employee benefit plans which are
governmental plans (as defined in Section 3(32) of ERISA) and certain church
plans (as defined in Section 3(33) of ERISA) are not subject to the fiduciary
responsibility provisions of ERISA.

                        FEDERAL INCOME TAX CONSEQUENCES

   The following is a general discussion by GATC of the anticipated material
federal income tax consequences of the purchase, ownership and disposition of
Pass Through Certificates. The summary is based on laws, regulations, rulings
and decisions now in effect, all of which are subject to change, possibly with
retroactive effect, or different interpretation. The discussion below does not
purport to address federal income tax consequences applicable to particular
categories of investors, some of which (for example, insurance companies,
dealers in securities, financial institutions or foreign investors) may be
subject to special rules. In addition, this summary is generally limited to
investors who will hold the Pass Through Certificates as "capital assets"
(generally, property held for investment) within the meaning of Section 1221 of
the Internal Revenue Code of 1986, as amended (the "Code"). Investors should
consult their own tax advisors in determining the federal, state, local, and
any other tax consequences to them of the purchase, ownership and disposition
of Pass Through Certificates, including the advisability of making any election
discussed below. Prospective investors should note that no rulings have been or
will be sought from the Internal Revenue Service (the "IRS") with respect to
any of the federal income tax consequences discussed below, and no assurance
can be given that the IRS will not take contrary positions. It is anticipated
that the Trusts will not be indemnified for any federal income taxes that may
be imposed upon them, and the imposition of any such taxes on any Trust could
result in a reduction in the amounts available for distribution to the
Certificateholders of such Trust.

   Mayer, Brown & Platt, counsel to GATC, has advised GATC that, in its
opinion, based upon its interpretation of analogous authorities under currently
applicable law, the Trusts will not be classified as associations taxable as
corporations, but, rather will be classified as grantor trusts under subpart E,
Part I of Subchapter J of the Code, and that each Certificateholder of a Trust
will be treated as the owner of a pro rata undivided interest in each of the
Equipment Notes or any other property held in such Trust.

General

   GATC believes that each Certificateholder in a Trust will be required to
report on its federal income tax return its pro rata share of the entire income
from the Equipment Notes or any other property held in such Trust, in
accordance with such Certificateholder's method of accounting. A
Certificateholder using the cash method of accounting should take into account
its pro rata share of income as and when received by the Pass Through Trustee
of such Trust. A Certificateholder using an accrual method of accounting should
take into account its pro rata share of income as it accrues or is received by
such Trustee, whichever is earlier.

                                       19
<PAGE>

   A purchaser of a Pass Through Certificate will be treated as purchasing an
interest in each Equipment Note and any other property in a Trust at a price
determined by allocating the purchase price paid for the Pass Through
Certificate among such Equipment Notes and other property in proportion to
their fair market values at the time of purchase of such Pass Through
Certificate. GATC believes that at the time of formation of a particular Trust,
the purchase price paid for a Pass Through Certificate with respect to such
Trust by an original purchaser of a Pass Through Certificate will be allocated
among the Equipment Notes in such Trust in proportion to their respective
principal amounts. The portion of such Certificateholder's purchase price
allocated to each Equipment Note will constitute such Certificateholder's
initial tax basis in such Equipment Note.

Sales of Pass Through Certificates

   A Certificateholder's tax basis in a Pass Through Certificate will equal its
cost of such Pass Through Certificate, reduced by any amortized premium (as
described below) and any payments other than interest made on such Pass Through
Certificate and increased by any market discount or original issue discount
included in the Certificateholder's income. A Certificateholder that sells a
Pass Through Certificate will recognize gain or loss (in the aggregate) in an
amount equal to the difference between its adjusted tax basis in the Pass
Through Certificate and the amount realized on the sale (except to the extent
attributable to accrued interest, which should be taxable as interest income)
and, if an Equipment Note or other asset of the related Trust is disposed of,
or an Equipment Note of the related Trust is prepaid, a Certificateholder will
recognize gain or loss (in the aggregate) in an amount equal to the difference
between such Certificateholder's adjusted tax basis in such Equipment Note or
other asset and the Certificateholder's pro rata portion of the amount realized
on the disposition by the Trust or upon such prepayment (except to the extent
attributable to accrued interest, which should be taxable as interest income).
Subject to the market discount provisions of the Code (described below), any
such gain or loss will be capital gain or loss if the Pass Through Certificate
was held as a capital asset and, if the Pass Through Certificate was held for
more than one year, will be long-term capital gain or loss to the extent the
Equipment Notes have been held by a Trust for more than one year. Any long-term
capital gains realized will be taxable under current law to corporate taxpayers
at the rates applicable to ordinary income, and to individual taxpayers at a
maximum marginal rate of 28%. Any capital losses realized will be deductible by
a corporate taxpayer only to the extent of capital gains and by an individual
taxpayer only to the extent of capital gains plus $3,000 of other income.

Market Discount

   A purchaser of a Pass Through Certificate will be considered to have
acquired an interest in an Equipment Note held in a Trust at a "market
discount" to the extent the remaining principal amount of such Equipment Note
allocable to the Pass Through Certificate exceeds the Certificateholder's tax
basis allocable to such Equipment Note, unless the excess does not exceed a
prescribed de minimis amount. In the event such excess exceeds the de minimis
amount, the Certificateholder will be subject to the market discount rules of
Sections 1276 and 1278 of the Code with regard to its interest in the Equipment
Note.

   In the case of a sale or other disposition of a Certificateholder's interest
in an Equipment Note subject to the market discount rules, Section 1276 of the
Code requires that gain, if any, from such sale or disposition be treated as
ordinary income to the extent such gain represents market discount that has
accrued during the period in which the interest was held by such
Certificateholder. In addition, a disposition of a Certificateholder's interest
in an Equipment Note by gift (and in certain other circumstances), could result
in the recognition of market discount income, computed as if such Note had been
sold for its fair market value.

   In the case of a partial principal payment on a Certificateholder's interest
in an Equipment Note subject to the market discount rules, Section 1276 of the
Code requires that such payment be included in gross income as ordinary income
to the extent such payment does not exceed the market discount that has accrued
during the period such interest was held by such Certificateholder. The amount
of any accrued market discount later required to be included in income upon a
disposition or subsequent partial principal payment, will be reduced by the
amount of accrued market discount previously included in income.


                                       20
<PAGE>

   Generally, market discount accrues under a straight line method, or, at the
election of the taxpayer, under a constant interest rate method. However, in
the case of bonds the principal of which may be paid in two or more
installments (such as the Equipment Notes), the manner in which market discount
is to be accrued will be described in Treasury regulations that have yet to be
issued. Until such Treasury regulations are issued, the explanatory Conference
Committee Report to the Tax Reform Act of 1986 (the "Conference Report")
indicates that holders of such obligations may elect to accrue market discount
either on the basis of a constant interest rate or as follows: (1) for those
obligations that have OID, market discount shall be deemed to accrue in
proportion to the accrual of OID for any accrual period, and (2) for those
obligations which do not have OID, the amount of market discount that is deemed
to accrue is the amount of market discount that bears the same ratio to the
total amount of remaining market discount that the amount of stated interest
paid in the accrual period bears to the total amount of stated interest
remaining to be paid on the obligation as of the beginning of such period.

   Under Section 1277 of the Code, if in any taxable year interest paid or
accrued by a Certificateholder on indebtedness incurred or continued to
purchase or carry its interest in an Equipment Note subject to the market
discount rules exceeds the interest (including OID) currently includible in
income with respect to such interest in an Equipment Note, deduction of such
interest must be deferred to the extent of the market discount allocable to the
taxable year. The deferred portion of any interest expense will generally be
deductible when such market discount is included in income upon the sale or
other disposition (including repayment) of the indebtedness.

   Section 1278 of the Code allows a taxpayer to make an election to include
market discount in its gross income currently. If such election is made, the
rules of Sections 1276 and 1277 (described above) will not apply to the
taxpayer.

   Due to the complexity of the market discount rules, prospective
Certificateholders are advised to consult their tax advisors as to the
applicability and operation of the market discount rules as they may apply to a
Certificateholder's interest in the Equipment Notes held by a Trust.

Premium

   A Certificateholder will generally be considered to have acquired an
interest in an Equipment Note at a premium to the extent the
Certificateholder's tax basis allocable to such interest exceeds the remaining
principal amount of the Equipment Note allocable to such interest. In that
event, a Certificateholder who holds a Pass Through Certificate as a capital
asset may amortize that premium as an offset to interest income under Section
171 of the Code, with corresponding reductions in the Certificateholder's tax
basis in its interest in the Equipment Note if an election under Section 171 of
the Code is or has been made with respect to all debt instruments held by the
taxpayer (including the Pass Through Certificates). Generally, such
amortization is on a constant yield basis. However, in the case of bonds the
principal of which may be paid in two or more installments (such as the
Equipment Notes), the Conference Report indicates a Congressional intent that
amortization will be in accordance with the same rules that will apply to the
accrual of market discount on such obligations (see the discussion of market
discount above).

   In the case of obligations which may be called at a premium prior to
maturity, amortizable bond premium may be determined by reference to an early
call date. Due to the complexities of the amortizable premium rules,
particularly where there is more than one possible call date and the amount of
any premium is uncertain, Certificateholders are urged to consult their own tax
advisors as to the amount of any amortizable premium and the advisability of
making the election.

Backup Withholding

   Payments made on the Pass Through Certificates and proceeds from the sale of
the Pass Through Certificates to or through certain brokers may be subject to a
"backup" withholding tax of 31% unless the Certificateholder complies with
certain reporting procedures or is an exempt recipient under Section 6049(b)(4)
of the Code. Any such withheld amounts will be allowed as a credit against the
Certificateholder's federal income tax.

                                       21
<PAGE>

                             CERTAIN ILLINOIS TAXES

   Mayer, Brown & Platt has advised GATC that, in its opinion, under existing
Illinois law as of the date hereof (i) the Trusts will not be classified as
associations taxable as corporations for purposes of franchise and income
taxation by the State of Illinois or any political subdivision thereof; (ii)
Certificateholders will be treated as the owners of undivided interests in the
assets of the Trusts for purposes of franchise and income taxation by the State
of Illinois and any political subdivision thereof; (iii) the Trusts will not be
subject to taxation or any other governmental fee or charge by the State of
Illinois or any political subdivision thereof; (iv) neither the Equipment Notes
nor the Pass Through Certificates will be subject to ad valorem taxation or any
other tax on intangible property by the State of Illinois or any political
subdivision thereof; (v) neither the delivery of the Equipment Notes to the
Trusts nor the acquisition, ownership or disposition of the interest of any
Certificateholder in any Pass Through Certificate will be subject to any sales,
use or transfer taxes imposed by the State of Illinois or any political
subdivision thereof; and (vi) a Certificateholder will not be subject to
taxation or any governmental fee or charge by the State of Illinois or any
political subdivision thereof, if a Certificateholder (a) is not a resident of
the State of Illinois, or otherwise subject to any tax, governmental charge or
fee imposed by the State of Illinois or any political subdivision thereof, (b)
does not otherwise have part of its receipt or income includible (either
directly or indirectly) in a tax return filed by a Certificateholder (or an
affiliate of the Certificateholder) in the State of Illinois, and (c) would not
be subject to taxation or any governmental fee or charge by the State of
Illinois if, instead of owning said Pass Through Certificates, the
Certificateholder owned its share of the assets of a Trust directly.

   Neither the Trusts nor the Certificateholders will be indemnified for any
state or local taxes imposed on them, and the imposition of any such taxes on a
Trust could result in a reduction in the amounts available for the distribution
to the Certificateholders of such Trust. In general, should a Certificateholder
or a Trust be subject to any state or local tax which would not be imposed if
the Pass Through Trustee were located in a different jurisdiction in the United
States, the Pass Through Trustee will resign and a new Trustee in such other
jurisdiction will be appointed.

                              PLAN OF DISTRIBUTION

   The Company may sell the Pass Through Certificates being offered hereby: (i)
through agents, (ii) to or through underwriters, (iii) through dealers, (iv)
directly to purchasers or (v) through a combination of any such methods of
sale.

   The distribution of the Pass Through Certificates may be effected from time

which may be changed, or (ii) at market prices prevailing at the time of sale,
or (iii) at prices related to such prevailing market prices, or (iv) at
negotiated prices.

   Offers to purchase the Pass Through Certificates may be solicited directly
by the Company or by agents designated by the Company from time to time. Any
such agent, which may be deemed to be an underwriter as that term is defined in

and any commissions payable by the Company to such agent will be set forth, in
the applicable Prospectus Supplement. Unless otherwise indicated in the
Prospectus Supplement, any such agent will be acting on a best efforts basis
for the period of its appointment.

   If an underwriter or underwriters are utilized in the sale, the Company will
execute an underwriting agreement with such underwriters at the time of sale to
them and the names of the underwriters and the terms of the transaction,
including commissions, discounts and other compensation of the underwriters and
dealers, if any, will be set forth in the Prospectus Supplement, which will be
used by the underwriters to make resales of the Pass Through Certificates in
respect of which this Prospectus is delivered to the public.

   If a dealer is utilized in the sale of the Pass Through Certificates in
respect of which this Prospectus is delivered, the Company or the Pass Through
Trustee, as the case may be, will sell such Pass Through Certificates

                                       22

to the dealer, as principal. The dealer may then resell such Pass Through
Certificates to the public at varying prices to be determined by such dealer at
the time of resale.

   Underwriters, dealers, agents and other persons may be entitled, under
agreements which may be entered into with the Company, to indemnification
against certain civil liabilities, including liabilities under the Securities
Act.

   Underwriters, dealers and agents may be customers of, engage in transactions
