                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
                                        
Note A    Basis of Presentation

Railcar Trust No. 1992-1 (the Trust) holds a majority interest in Railcar
Associates, LP, a limited partnership (the Partnership). The Partnership leases
approximately 59,000 railcars within the United States. GE Railcar Associates,
Inc. (the Lessee) is the sole lessee of the railcars. The leases mature in 2004
with quarterly fixed rental payments totaling approximately $153 million
annually. These rental payments are guaranteed by General Electric Capital
Corporation (GECC). The Lessee has an option to purchase all, but not less than
all, of the railcars under lease for approximately $500 million at the end of
the lease. The Lessee is responsible for maintenance, taxes, insurance and other
expenses involved with operating the railcars.

The Lessee has an annual obligation to make certain contingent rental payments
to the Partnership in addition to the previously described quarterly fixed
rental payments ("Additional Rent"). The Additional Rent calculation is prepared
by the Lessee and is subject to verification by an independent auditor. Prior to
1998, Additional Rent was recorded when independent verification was received
due to the lack of information available to the lessor. In 1998, in a change in
accounting estimate due to additional information becoming available,
approximately $11 million in Additional Rent was recorded related to 1997 and
1998. Cash of $7 million relating to 1997 Additional Rent was received by the
Trust in the first quarter and will be distributed in the second quarter on a
prorata basis to the holders of the Beneficial Interests in the Trust. The 1998
estimate of Additional Rent is $4 million which has not been verified by an
independent auditor.

The accompanying consolidated financial statements should be read in conjunction
with the consolidated financial statements included in the Trust's Annual Report
on Form 10-K for the year ended December 31, 1998. The consolidated financial
information furnished herein reflects all adjustments (consisting of normal
recurring accruals) which are, in the opinion of management, necessary for a
fair presentation of the consolidated statements for the periods shown.

The partnership has the following partners:

Limited Partnership.

Note B    Summary of Significant Accounting Policies

Principles of Consolidation: The consolidated financial statements include the
financial results of the Trust and the Partnership. All interentity transactions
have been eliminated.

Use of Estimates: The preparation of financial statements requires management to
make estimates and assumptions that affect amounts reported in the financial
statements and accompanying notes. Such estimates and assumptions could change
in the future as more information becomes known which could impact the amounts
reported and disclosed herein.

Cash, Cash Equivalents, and Restricted Cash: The Trust considers all highly
liquid investments with an original maturity of three months or less to be cash
equivalents. Due to the short maturity of these instruments, the carrying amount
approximates fair value. Restricted cash balances represent short-term
investments held by GECC. The investments are restricted as to the availability
to the Partnership and are available only to service principal and interest
payments on the Partnership's debt.

Rental Equipment: Rental equipment (railcars) are carried at cost, which is
based upon the historical cost of the contributing partners. Railcars are
depreciated to estimated residual value using the straight-line method over the
term of the leases.

ITEM 2.   Management's Discussion and Analysis of Financial Condition and
          Results of Operations

Financial Liquidity and Capital Resources

Substantially all of the physical property of the Trust, consisting primarily of
railcars, was contributed to the Partnership of which the Trust is a 98.99%
partner. At such time, the Partnership assumed the Assumed Indebtedness. The
Partnership then leased to the Lessee all of the property contributed by the
Trust, along with other railcars it received as a contribution from its other
partners. Financing of the Trust was accomplished by issuance of $998 million of
Trust Notes secured by the Trust's ownership interest in the Partnership. No new
borrowings have occurred during 1999.

Debt Maturities and Repayments

Current maturities of long-term debt of $103.4 million at March 31, 1999
represent debt which is being serviced by cash flow from the leases.

Results of Operations

Fixed rental receipts by the Partnership under the Leases are used to service
the Assumed Indebtedness and other expenses of the Partnership. Remaining
Partnership available cash is distributed to the partners, the Trust's share of
which must be used by the Trust to service the Trust Notes.

During the first three months of both 1999 and 1998, on a consolidated basis the
Trust received rental revenues of $38.3 million pursuant to the Leases.
Operating income was $25.8 million and $25.7 million for the first three months
of 1999 and 1998, respectively. Interest expense, net, was $13.3 million and
$15.3 million for the first three months of 1999 and 1998, respectively. The
reduction of interest expense was due to scheduled repayments of Trust Notes and
Assumed Indebtedness. Consolidated net income of the Trust was $12.3 million and
$10.2 million for the first three months of 1999 and 1998, respectively.

The Trust generated $32.7 million in cash from operating activities during the
first three months of 1999. Those amounts were used to repay the Assumed
Indebtedness and the Trust Notes as payments became due. Of the net cash from
operating activities, $24.9 million was used in order to reduce borrowings and
$.5 million was distributed to the minority interests in the Partnership. The
principal amount outstanding under the Assumed Indebtedness was decreased by $.4
million to a total of $27.5 million at quarter-end, and the principal amount
outstanding under the Trust Notes was decreased by $24.5 million to a total
amount of $618.0 million at quarter-end.

During first quarter 1999, no distributions were made to the holders of the
Beneficial Interests in the Trust.

Impact of the Year 2000

The Year 2000 Issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Due to the nature of the
Trust, the Year 2000 implications are not material. The railcars owned by the
Trust are leased on a twelve-year contract expiring in 2004. The Trust received
quarterly lease payments totaling $153 million that provided the majority of the
revenue. The Trust was designed to operate solely on the lease payments. The
Trust's exposure to the Year 2000 is the possible impact on any Additional Rent.
Additional Rent can be received by the Trust if income generated by the railcars
exceeds specific contractual parameters. Additional Rent could be reduced or
eliminated if the Year 2000 problems result in a decline in railcar usage. While
it is beyond the ability of the Trust to forecast the effect, the impact will
not affect the Trust's ability to repay its indebtedness.
