Item 7. Financial Statements and Exhibits

(b) Pro Forma Financial Information

On October 26, 2001, Trinity Industries, Inc. ("Trinity") completed its merger
transaction between a wholly-owned subsidiary of Trinity and privately owned
Thrall Car Manufacturing Company ("Thrall"). Thrall is a leading railcar
manufacturer, with operations in both the United States and Europe. Under terms
of the agreement, Trinity paid $165.5 million in cash and issued 7.15 million
shares of its common stock at the closing. Additional estimated amounts have
been accrued related to the working capital adjustment per the merger agreement
($15.2 million) and transaction fees ($5.6 million). In addition, Trinity under
certain circumstances has agreed to make additional payments, not to exceed $45
million over five years, based on a formula related to annual railcar industry
production levels. The unaudited pro forma condensed consolidated Statement of
Operations is based on the historical consolidated financial statements of
Trinity and Thrall, adjusted to give effect to the transactions described
herein.

The unaudited pro forma condensed consolidated Statement of Operations is for
the nine months ended December 31, 2001 and gives effect to the transaction as
if it had occurred as of April 1, 2001. In September 2001, Trinity changed its
year-end to December 31 from March 31. Thrall's historical information is for
the seven months ended October 26, 2001. The post acquisition period of October
26, 2001 to December 31, 2001 is included in the historical data for the nine
months ended December 31, 2001 for Trinity.

The merger of Thrall and the related adjustments are described in the
accompanying notes. The pro forma adjustments are based upon available
information and certain assumptions that we believe are reasonable. In our
opinion, all adjustments that are necessary to present fairly the pro forma data
have been made. The unaudited pro forma condensed consolidated Statement of
Operations does not purport to represent what the results of operations would
actually have been had the transaction in fact occurred on such dates or to
project the results of operations for any future period or date. The unaudited
pro forma condensed consolidated Statement of Operations should be read in
conjunction with the historical consolidated financial statements of Trinity and
Thrall and Management's Discussion and Analysis of Financial Condition and
Results of Operations. Pro Forma results include after-tax charges of $50.4
million ($1.30 per share) related to restructuring the Rail group in connection
with the Thrall merger and the down cycle in the railcar industry and other
matters. These restructuring charges were recorded in the quarter ended December
31, 2001.

The merger of Thrall has been accounted for as a purchase and the purchase price
has been allocated to the assets acquired and liabilities assumed based upon
estimated fair market values. The purchase price allocation for the Thrall
merger is subject to change when additional information concerning asset and
liability valuations is obtained.

The historical consolidated statements of operations of Trinity and Thrall were
prepared in accordance with generally accepted accounting principles.

Notes to Unaudited Pro Forma Consolidated Statement of Operations

Note 1: Pro Forma Adjustments

The following pro forma adjustments have been applied to the accompanying
historical condensed consolidated statement of operations of Trinity and Thrall
to give effect to the Thrall merger and related financing transaction as if they
had all occurred on April 1, 2001:

(a)      Eliminate revenues from a non-rail subsidiary not included in the
         transaction.

(b)      Eliminate cost of revenues from a non-rail subsidiary referenced in (a)
         that was not included in the transaction - $1.0 million.

(c)      Eliminate the costs of a Thrall facility not included in the
         transaction subsequent to it's shutdown at the end of March 2001 - $2.5
         million.

(d)      Increase interest expense related to financing the cash portion of the
         purchase price - $5.6 million.

(e)      Eliminate interest expense related to Thrall investments and loan
         portfolios not included in the transaction - $1.5 million.

(f)      Eliminate unrealized gains related to Thrall investments and loan
         portfolios not included in the transaction.

         qualified subsidiary of a Sub Chapter S corporation, Thrall's
         historical statement of operations is not required to record a federal
         income tax provision.

(h)      Record tax effect @ 37.5% of pro forma income before tax.
