                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

ITEM 1.   DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED

         On March 11, 1999, the Board of Directors of Trinity Industries, Inc.
(the "Company") declared a dividend distribution of one right (a "Right") for
each outstanding share of the Company's common stock, $1.00 par value (the
"Common Stock"), to stockholders of record at the close of business on April 27,
1999. See the Company's Registration Statement on Form 8-A, filed April 2, 1999
for a complete description of the Rights Agreement (the "Rights Agreement")
between the Company and The Bank of New York, as Rights Agent (the "Rights
Agent").

         On August 13, 2001, the Company, TCMC Acquisition Corp., an Illinois
corporation and wholly owned subsidiary of the Company ("Merger Sub"), Thrall
Car Management Company, Inc., a Delaware corporation ("Newco"), and Thrall Car
Manufacturing Company, an Illinois corporation and wholly owned subsidiary of
Newco ("Thrall"), entered into an Agreement and Plan of Merger (the "Merger
Agreement"). Subject to the terms and conditions of the Merger Agreement, Merger
Sub will merge with and into Thrall and Thrall will become a wholly owned
subsidiary of the Company. In the Merger, Newco will receive (a) One Hundred
Sixty-Five Million Five Hundred Thousand Dollars ($165,500,000) in cash, (b)
Seven Million One Hundred Fifty Thousand (7,150,000) shares of Common Stock and
(c) the right to receive additional payments of up to Forty-Five Million Dollars
($45,000,000)) over a five year period, based on a formula related to the
annual railcar industry productions levels.

         In connection with the Merger Agreement, the Company and the Rights
Agent have amended the terms of the Rights Agreement (the "Amendment") so that
Newco shall only be considered an "Acquiring Person" (as defined in the Rights
Agreement) when Newco, alone or together with all Affiliates (as defined in the
Rights Agreement) and Associates (as defined in the Rights Agreement), shall be
the Beneficial Owner (as defined in the Rights Agreement) of more than 20% of
the shares of Common Stock then outstanding (after including the shares of
Common Stock acquired, or subject to acquisition, by Newco under or pursuant to
the Merger Agreement). The Amendment further provides that a stockholder of
Newco shall only be considered an "Acquiring Person" when the stockholder, alone
or together with all Affiliates and Associates, shall be the Beneficial Owner of
more than 20% of the shares of Common Stock then outstanding (after including
the shares of Common Stock acquired, or subject to acquisition, by Newco under
or pursuant to the Merger Agreement).

         This summary description of the Amendment does not purport to be
complete and is qualified in its entirety by reference to the Amendment,
incorporated by reference herein.
