President's Message

Dear Investor:

I am pleased to present the Semi-Annual Report to Shareholders for Federated
Intermediate Income Fund, a portfolio of Federated Income Securities Trust.
The Report covers the six-month period ending October 31, 1998. It begins
with a review of the bond market by the fund's portfolio manager, which is
followed by a complete list of fund holdings and its financial statements.
On behalf of income-oriented investors, the fund invests in a diversified
portfolio consisting primarily of intermediate-term, high-quality debt
securities. At the end of the reporting period, the fund's portfolio was
invested primarily in corporate bonds (60.2%), followed by mortgage-backed
securities (11.4%), U.S. Treasury securities (11.4%), government agency
securities (8.2%), a repurchase agreement (3.9%), asset-backed securities
(3.5%), preferred stocks (1.0%), and a collateralized mortgage obligation
(0.2%).

During the reporting period, Institutional Shares produced a total return of
4.51%* through dividends totaling $0.30 per share and a net asset value
increase of $0.15 per share. Institutional Service Shares produced a total
return of 4.38%* through dividends of $0.29 per share and a net asset value
increase of $0.15 per share.

Total net assets in the fund reached $197.1 million at the period's end.
Thank you for selecting Federated Intermediate Income Fund as a high-quality
income investment. As always, we welcome your questions, comments, or
suggestions.

Sincerely,

Investment Review

Federated Intermediate Income Fund invests primarily in high quality corporate

debt securities rated in one of the four highest categories (A or better) by a

nationally recognized statistical rating organization. The fund may also

invest in other high quality government and asset-backed securities. The fund

duration is managed within a range of three to seven years.

The six-month period ended October 31, 1998, was very positive for most fixed

income investors, particularly those in the highest quality debt sectors.

Interest rate levels declined significantly over the reporting period for all

points along the U.S. Treasury maturity spectrum. The largest rate decrease

occurred in the two year treasury maturity, which fell approximately 145

basis points in yield. There were two predominant reasons for the interest

rate decline: 1) a slower growth economic environment, and 2) dramatic

economic/financial marketplace volatility in non-U.S. markets.

Throughout much of calendar year 1998, corporate earnings have been

considerably below initial Wall Street analyst expectations. The

corresponding concern over the future growth potential of the U.S. economy,

in combination with sustained low inflation, caused U.S. Treasury yields to

fall. Additionally, the global financial marketplace became far more unstable

over the reporting period. Problems emanating out of Asia in the second half

of 1997 quickly spread to Russia and Latin America during the first three

quarters of 1998. The result was a worldwide "flight to quality" into U.S.

Treasury securities. As the reporting period was coming to a close, the

Federal Reserve Board reversed monetary policy and twice decreased the

federal rate, creating a further rally in high quality bonds.

In terms of relative performance within the various fixed income sectors, the

general rule over the past year was that higher quality outperformed lower

quality bonds and domestic outperformed international bonds. The star

performers were U.S. Treasuries, perceived to be the highest quality

investment worldwide. All other investment grade sectors (corporate,

mortgages, asset-backs) produced positive rates of return, but fell short of

U.S. Treasuries. As one moved into below investment grade and international

emerging market debt securities, the returns were modestly positive or

negative over the fiscal year period.

Fund duration was maintained within a relatively tight range over the

reporting period at just over five years. The portfolio composition was

slightly upgraded in quality with incremental cash flows moving into the

U.S. government sector. For the six-month period ended October 31, 1998, the

fund's Institutional Shares and Institutional Service Shares generated a

total return of 4.51%* and 4.38%,* respectively, reflecting income plus the

capital appreciation caused by falling interest rates, but partially offset

by corporate bonds underperforming U.S. Treasury securities.

 * Performance quoted represents past performance and is not indicative of

future results. Investment return and principal value will fluctuate, so

that an investor's shares, when redeemed, may be worth more or less than

their original cost.

Notes to Financial Statements

Federated Intermediate Income Fund
October 31, 1998 (unaudited)

Organization

Federated Income Securities Trust (the "Trust") is registered under the

Investment Company Act of 1940, as amended (the "Act") as an open-end,

management investment company. The Trust consists of two portfolios. The

financial statements included herein are only those of Federated

Intermediate Income Fund (the "Fund"). The investment objective of the Fund

is to provide current income. The financial statements of the other

portfolios are presented separately. The assets of each portfolio are

segregated and a shareholder's interest is limited to the portfolio in which

shares are held.

The Fund offers two classes of shares: Institutional Shares and Institutional

Service Shares.

Significant Accounting Policies

The following is a summary of significant accounting policies consistently

followed by the Fund in the preparation of its financial statements. These

policies are in conformity with generally accepted accounting principles.

Investment Valuations

U.S. government securities, listed corporate bonds, other fixed income and

asset-backed securities, and private placement securities are generally

valued at the mean of the latest bid and asked price as furnished by an

independent pricing service. Listed equity securities are valued at the last

sale price reported on a national securities exchange. Short-term securities

are valued at the prices provided by an independent pricing service. However,

short-term securities with remaining maturities of sixty days or less at the

time of purchase may be valued at amortized cost, which approximates fair

market value.

Repurchase Agreements

It is the policy of the Fund to require the custodian bank to take

possession, to have legally segregated in the Federal Reserve Book Entry

System, or to have segregated within the custodian bank's vault, all

securities held as collateral under repurchase agreement transactions.

Additionally, procedures have been established by the Fund to monitor, on a

daily basis, the market value of each repurchase agreement's collateral to

ensure that the value of collateral at least equals the repurchase price to

be paid under the repurchase agreement transaction.

The Fund will only enter into repurchase agreements with banks and other

recognized financial institutions, such as broker/dealers, which are deemed

by the Fund's adviser to be creditworthy pursuant to the guidelines and/or

standards reviewed or established by the Board of Trustees (the "Trustees").

Risks may arise from the potential inability of counterparties to honor the

terms of the repurchase agreement. Accordingly, the Fund could receive less

than the repurchase price on the sale of collateral securities.

Investment Income, Expenses, and Distributions

Interest income and expenses are accrued daily. Bond premium and discount, if

applicable, are amortized as required by the Internal Revenue Code, as

amended (the "Code"). Distributions to shareholders are recorded on the ex-

dividend date.

Federal Taxes

It is the Fund's policy to comply with the provisions of the Code applicable

to regulated investment companies and to distribute to shareholders each year

substantially all of its income. Accordingly, no provisions for federal tax

are necessary.

When-Issued and Delayed Delivery Transactions

The Fund may engage in when-issued or delayed delivery transactions. The Fund

records when-issued securities on the trade date and maintains security

positions such that sufficient liquid assets will be available to make

payment for the securities purchased. Securities purchased on a when-issued

or delayed delivery basis are marked to market daily and begin earning

interest on the settlement date.

Restricted Securities

Restricted securities are securities that may only be resold upon

registration under federal securities laws or in transactions exempt from

such registration. In some cases, the issuer of restricted securities has

agreed to register such securities for resale, at the issuer's expense,

either upon demand by the Fund or in connection with another registered

offering of the securities. Many restricted securities may be resold in the

secondary market in transactions exempt from registration. Such restricted

securities may be determined to be liquid under criteria established by the

Trustees. The Fund will not incur any registration costs upon such resales.

The Fund's restricted securities are valued at the price provided by dealers

in the secondary market or, if no market prices are available, at the fair

value as determined by the Fund's pricing committee.

Additional information on each restricted security held at October 31, 1998,

is as follows:

</TABLE>

Dollar Roll Transactions

The Fund enters into dollar roll transactions, with respect to mortgage

securities issued by GNMA, FNMA, and FHLMC, in which the Fund sells mortgage

securities to financial institutions and simultaneously agrees to accept

substantially similar (same type, coupon, and maturity) securities at a later

date at an agreed upon price. Dollar roll transactions involve "to be

announced" securities and are treated as short-term financing arrangements

which will not exceed twelve months. The Fund will use the proceeds generated

from the transactions to invest in short-term investments, which may enhance

the Fund's current yield and total return.

Use of Estimates

The preparation of financial statements in conformity with generally

accepted accounting principles requires management to make estimates and

assumptions that affect the amount of assets, liabilities, expenses, and

revenues reported in the financial statements. Actual results could differ

from those estimated.

Other

Investment transactions are accounted for on the trade date.

Shares of Beneficial Interest

The Declaration of Trust permits the Trustees to issue an unlimited number of

full and fractional shares of beneficial interest (without par value) for

each class of shares. Transactions in shares were as follows:

Investment Advisory Fee and Other Transactions with Affiliates
Investment Advisory Fee
Federated Management, the Fund's investment adviser (the "Adviser"),

receives for its services an annual investment advisory fee equal to 0.50% of

the Fund's average daily net assets. The Adviser may voluntarily choose to

waive any portion of its fee. The Adviser can modify or terminate this

voluntary waiver at any time at its sole discretion.

Administrative Fee

Federated Services Company ("FServ"), under the Administrative Services

Agreement, provides the Fund with administrative personnel and services. The

fee paid to FServ is based on the level of average aggregate daily net assets

of all funds advised by subsidiaries of Federated Investors, Inc. for the

period. The administrative fee received during the period of the

Administrative Services Agreement shall be at least $125,000 per portfolio

and $30,000 per each additional class of shares.

Distribution Services Fee

The Fund has adopted a Distribution Plan (the "Plan") pursuant to Rule 12b-1

under the Act. Under the terms of the Plan, the Fund will compensate

Federated Securities Corp. ("FSC"), the principal distributor, from the net

assets of the Fund to finance activities intended to result in the sale of the

Fund's Institutional Service Shares. The Plan provides that the Fund may

incur distribution expenses up to 0.25% of average daily net assets of the

Institutional Service Shares, annually, to compensate FSC. The distributor

may voluntarily choose to waive any portion of its fee. The distributor can

modify or terminate this voluntary waiver at any time at its sole discretion.

Shareholder Services Fee

Under the terms of a Shareholder Services Agreement with Federated

Shareholder Services ("FSS"), the Fund will pay FSS up to 0.25% of average

daily net assets of the Fund for the period. The fee paid to FSS is used to

finance certain services for shareholders and to maintain shareholder

accounts. FSS may voluntarily choose to waive any portion of its fee. FSS can

modify or terminate this voluntary waiver at any time at its sole discretion.

Transfer and Dividend Disbursing Agent Fees and Expenses

FServ, through its subsidiary, Federated Shareholder Services Company

("FSSC") serves as transfer and dividend disbursing agent for the Fund. The

fee paid to FSSC is based on the size, type, and number of accounts and

transactions made by shareholders.

Portfolio Accounting Fees

FServ maintains the Fund's accounting records for which it receives a fee.

The fee is based on the level of the Fund's average daily net assets for the

period, plus out-of-pocket expenses.

General

Certain of the Officers and Trustees of the Trust are Officers and Directors

or Trustees of the above companies.

Investment Transactions

Purchases and sales of investments, excluding short-term securities, for the

period ended October 31, 1998, were as follows:

Purchases                   $32,125,196
Sales                       $18,212,447

Year 2000

Similar to other financial organizations, the Fund could be adversely

affected if the computer systems used by the Fund's service providers do not

properly process and calculate date-related information and data from and

after January 1, 2000. The Fund's Adviser and Administrator are taking

measures that they believe are reasonably designed to address the Year 2000

issue with respect to computer systems that they use and to obtain reasonable

assurances that comparable steps are being taken by each of the Fund's other

service providers. At this time, however, there can be no assurance that

these steps will be sufficient to avoid any adverse impact to the Fund.

PRESIDENT'S MESSAGE

Dear Investor:

I am pleased to present the Semi-Annual Report to Shareholders for Federated
Short-Term Income Fund, a portfolio of Federated Income Securities Trust. The
report covers the six-month period ended October 31, 1998. It begins with a
review of the bond market by the fund's portfolio manager, which is followed
by a complete list of fund holdings and its financial statements.

On behalf of conservative, income-oriented investors, the fund invests in a
diversified portfolio consisting primarily of short-term, high-quality debt
securities. At the end of the reporting period, the fund's portfolio was
invested primarily in corporate bonds/asset-backed securities (58.0%),
followed by mortgage-backed securities (34.9%), U.S. Treasury notes (6.2%),
and a repurchase agreement (1.0%).

During the reporting period, Institutional Shares produced a total return of
3.29%* through dividends totaling $0.26 per share and a net asset value
increase of $0.02 per share. Institutional Service Shares produced a total
return of 3.16%* through dividends totaling $0.25 per share and a net asset
value increase of $0.02 per share.

Net assets in the fund totaled $211.3 million at the reporting period's end.

Thank you for selecting Federated Short-Term Income Fund as a high-quality,
short-term income investment. As always, we welcome your questions,
comments, or suggestions.

Sincerely,

[Graphic]

Glen R. Johnson
President
December 15, 1998

INVESTMENT REVIEW

Federated Short Term Income Fund represents a high quality, fixed income
portfolio combining various fixed income asset classes. Investments are
concentrated in U.S. Treasury, government agency, and high quality corporate
debt securities. The investment objective of the fund is to seek to provide
current income. To the extent consistent with this objective, the fund will
strive to minimize fluctuation in principal value through a portfolio with
an effective average life of no greater than three years, but generally
having a portfolio duration of no greater than two years.

The fund's reporting period was characterized by two distinctly different
three-month periods. The first period was a "steady-as-she-goes" period where
the fund performed in line with historical precedent, in other words, as
expected. The second period, which began in July, was characterized by
extreme volatility triggered by global economic and credit concerns. This
period featured unprecedented spread widening in all sectors, even off-the-
run treasury securities. While as of this writing the market has stabilized
somewhat, the negative effects of the current economic environment continue
to be felt on the portfolio.

As the fund invests primarily in spread securities (i.e., securities whose
yields are based on some premium over, or "spread" off of, treasury yields),
the spread widening resulting from the global "flight to quality" mentioned
above caused the fund to underperform its index benchmarks. The significant
percentage of the fund allocated to mortgage-backed and asset-backed
securities (approximately two-thirds at the end of the reporting period under
review) had a further negative effect, as some of these latter securities
combine both credit and prepayment risk and experienced "the worst of both
worlds" (prepayment risk is the tendency of amortizing securities to pay off
more quickly when interest rates decline and more slowly when they rise). The
fund's duration posture over the period was maintained either at or slightly
above the midpoint of its range of one to two years and is expected to remain
there going forward. This positioning produced a slightly positive effect on
performance during the period under review.

For the six months ended October 31, 1998, Institutional Shares produced a
3.29%* total return, and Institutional Service Shares produced a 3.16%* total
return, compared to a 4.67% total return for the Merrill Lynch 1-3 Year
Treasury Bond Index** and a 4.07% total return for the Merrill Lynch 1-3 Year
Corporate Bond Index.** The durations of these indices (1.65 years and 1.82
years, respectively, as of 10/31/98) are both longer than that of the fund's
own duration midpoint (1.5 years). Thus the fund underperformed these indices,
given the significant decline in treasury yields during the reporting period
and as a result of the spread-widening effect mentioned above. Despite a
difficult six months, fund management believes the underlying credit quality
of its portfolio to be excellent and its positioning with regard to interest
rate risk to be prudent. Individual opportunities to add value by accepting
reasonable levels of credit and convexity risk will continue to be sought,
with a general bias toward credit upgrading in light of a slowly decelerating
economy.

 *  Performance quoted represents past performance and is not indicative of
future results. Investment return and principal value will fluctuate, so
that an investor's shares, when redeemed, may be worth more or less than
their original cost.

 ** The Merrill Lynch 1-3 Year Treasury Bond Index is an unmanaged index
tracking short-term U.S. government securities between 1 and 2.99 years.

trading maturities between 1 and 2.99 years. Investments cannot be made in
an index.

NOTES TO FINANCIAL STATEMENTS
FEDERATED SHORT-TERM INCOME FUND

OCTOBER 31, 1998 (UNAUDITED)

ORGANIZATION

Federated Income Securities Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of two portfolios. The
financial statements included herein are only those of Federated Short-Term
Income Fund (the "Fund"). The financial statements of the other portfolios
are presented separately. The assets of each portfolio are segregated and a
shareholder's interest is limited to the portfolio in which shares are held.
The investment objective of the Fund is to seek to provide current income.
The Fund offers two classes of shares: Institutional Shares and Institutional
Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS

U.S. government securities, listed corporate bonds, other fixed income and
asset-backed securities, unlisted securities and private placement
securities are generally valued at the mean of the latest bid and asked price
as furnished by an independent pricing service. Short-term securities are
valued at the prices provided by an independent pricing service. However,
short-term securities with remaining maturities of sixty days or less at the
time of purchase may be valued at amortized cost, which approximates fair
market value.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book Entry
System, or to have segregated within the custodian bank's vault, all
securities held as collateral under repurchase agreement transactions.
Additionally, procedures have been established by the Fund to monitor, on a
daily basis, the market value of each repurchase agreement's collateral to
ensure that the value of collateral at least equals the repurchase price to
be paid under the repurchase agreement transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/dealers, which are deemed
by the Fund's adviser to be creditworthy pursuant to the guidelines and/or
standards reviewed or established by the Board of Trustees (the "Trustees").
Risks may arise from the potential inability of counterparties to honor the
terms of the repurchase agreement. Accordingly, the Fund could receive less
than the repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES, AND DISTRIBUTIONS

Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as
amended (the "Code"). Distributions to shareholders are recorded on the ex-
dividend date.

FEDERAL TAXES

It is the Fund's policy to comply with the provisions of the Code applicable
to regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax
are necessary.

At April 30, 1998, the Fund, for federal tax purposes, had a capital loss
carryforward, as noted below, which will reduce the Fund's taxable income
arising from future net realized gain on investments, if any, to the extent
permitted by the Code, and thus will reduce the amount of the distributions
to shareholders which would otherwise be necessary to relieve the Fund of any
liability for federal tax.
Pursuant to the Code, such capital loss carryforward will expire as follows:
EXPIRATION YEAR     EXPIRATION AMOUNT

     1999              $ 1,132,354
     2000                4,105,766
     2002                  669,532
     2003                5,572,713
     2004               10,784,773
     2005                1,566,031
     2006                  696,886

Additionally, net capital losses of $208,810 attributable to security
transactions incurred after October 31, 1997, are treated as arising on the
first day of the Fund's next taxable year.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may engage in when-issued or delayed delivery transactions. The Fund
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make
payment for the securities purchased. Securities purchased on a when-issued
or delayed delivery basis are marked to market daily and begin earning
interest on the settlement date.

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon
registration under federal securities laws or in transactions exempt from
such registration. In some cases, the issuer of restricted securities has
agreed to register such securities for resale, at the issuer's expense either
upon demand by the Fund or in connection with another registered offering of
the securities. Many restricted securities may be resold in the secondary
market in transactions exempt from registration. Such restricted securities
may be determined to be liquid under criteria established by the Board of
Trustees. The Fund will not incur any registration costs upon such resales.
The Fund's restricted securities are valued at the price provided by dealers
in the secondary market or, if no market prices are available, at the fair
value as determined by the Fund's pricing committee.
Additional information on each restricted security held at October 31, 1998
is as follows:

Federated Securities Corp. ("FSC"), the principal distributor, from the net
assets of the Fund to finance activities intended to result in the sale of
the Fund's Institutional Service Shares. The Plan provides that the Fund may
incur distribution expenses up to 0.25% of the average daily net assets of

may voluntarily choose to waive any portion of its fee. The distributor can
modify or terminate this voluntary waiver at any time at its sole

YEAR 2000

Similar to other financial organizations, the Fund could be adversely
affected if the computer systems used by the Fund's service providers do not
properly process and calculate date-related information and data from and
after January 1, 2000. The Fund's Adviser and Administrator are taking
measures that they believe are reasonably designed to address the Year 2000
issue with respect to computer systems that they use and to obtain reasonable
assurances that comparable steps are being taken by each of the Fund's other
service providers. At this time, however, there can be no assurance that
these steps will be sufficient to avoid any adverse impact to the Fund.
