               The description of the Preferred Stock Purchase
     Rights registered hereby is incorporated by reference to
     the description contained under the heading "Description
     of Securities to be Registered" in the Registration
     Statement Of Certain Classes Of Securities on Form 8-A,
     filed with the Securities and Exchange Commission (the
     "Commission") on May 2, 1989.
     
               Additionally, on May 6, 1997, Trinity Indus-
     tries, Inc. (the "Company") amended the terms of the Pre-
     ferred Stock Purchase Rights by amending the Rights
     Agreement (the "Rights Agreement") dated April 11, 1989,
     between the Company and NCNB Texas National Bank, prede-
     cessor to The Bank of New York ("Amendment No. 1"). 
     Amendment No. 1 modifies the Rights Agreement in several
     areas: (i) the definition of "Acquiring Person" has been
     amended to (A) reduce to 10% the threshold of Beneficial
     Ownership of Common Stock resulting in a Person becoming
     an Acquiring Person and (B) provide a limited exception
     therefrom for certain Persons entitled to report owner-
     ship (but less than 15%) on SEC Schedule 13G who either
     (x) beneficially owned, on May 6, 1997, 10% or more of
     the outstanding shares of Common Stock and do not at any
     time become the Beneficial Owner of 15% or more of the
     outstanding shares of Common Stock or (y) upon request of
     the Company, certify that such Persons acquired shares of
     Common Stock in excess of 9.99% inadvertently and who
     thereafter do not acquire additional shares of Common
     Stock while the Beneficial Owner of 10% or more of the
     shares of Common Stock then outstanding and dispose of
     the portion of such Common Stock in excess of 9.99%; (ii)
     Section 11(a)(ii) has been amended to provide that a
     flip-in event shall occur upon any Person becoming an
     Acquiring Person; (iii) Section 13(a) has been amended to
     provide that the flip-over provision shall apply whether
     or not a Stock Acquisition Date has occurred; (iv) Sec-
     tion 23 has been amended to revise the exception to the
     requirement for the concurrence of Continuing Directors
     in a redemption, set forth in clause (y) of the proviso
     to the first sentence, to apply only to Qualifying Offers
     (i.e., offers for all shares determined by a majority of
     the Continuing Directors who are not officers of the
     Registrant to be at a price which is fair to stockholders
     and otherwise in the best interests of the Company and
     its stockholders); and (v) Section 26 has been amended to
     provide that any amendment to the Rights Agreement fol-
     lowing a Stock Acquisition Date or a change (resulting
     from a proxy or consent solicitation) in a majority of
     the Board of Directors under certain circumstances (un-
     less the solicitation occurs concurrent with a Qualifying
     Offer) shall require the concurrence of Continuing Direc-
     tors.  The description of Amendment No. 1 contained
     herein is not complete and is qualified in its entirety
     by reference to Amendment No. 1 which is filed as an
     exhibit hereto and which is incorporated by reference
     herein.  Capitalized terms not defined herein, will have

     between Trinity Industries, Inc., a Delaware corporation
     (the "Company"), and The Bank of New York (the "Rights
     Agent").
     
               WHEREAS, the Company and NCNB Texas National
     Bank, predecessor to the Rights Agent, have heretofore
     executed and entered into a Rights Agreement, dated as of
     April 11, 1989 (the "Rights Agreement"), setting forth
     the terms of Preferred Stock Purchase Rights of the
     Company (the "Rights"); and
     
               WHEREAS, the Company and the Rights Agent may
     from time to time supplement or amend the Rights Agree-
     ment pursuant to the provisions of Section 26 of the
     Rights Agreement; and
     
               WHEREAS, all acts and things necessary to make
     this Amendment No. 1 a valid, legal and binding instru-
     ment of the Company and the Rights Agent have been duly
     done, performed and fulfilled, and the execution and
     delivery hereof by each of the Company and the Rights
     Agent have been in all respects duly authorized by the
     Company and the Rights Agent, respectively.
     
               NOW, THEREFORE, the Company and the Rights
     Agent hereby agree as follows:
     
               1.   Pursuant to Section 26 of the Rights
     Agreement, Section 1(a) of the Rights Agreement is hereby
     amended to read in its entirety as follows:
     
            "(a) "Acquiring Person" shall mean any Person
            (as such term is hereinafter defined) who or which,
            together with all Affiliates and Associates of such
            Person, shall be the Beneficial Owner (as such term
            is hereinafter defined) of 10% or more of the shares
            of Common Stock of the Company then outstanding, but
            shall not include the Company, any Subsidiary of the
            Company, any employee benefit plan of the Company or
            of any Subsidiary of the Company, or any Person or
            entity holding shares of Common Stock of the Company
            for or pursuant to the terms of any such plan. 
            Notwithstanding the foregoing, (i) no Person shall
            become an "Acquiring Person" solely as the result of
            an acquisition of shares of Common Stock by the
            Company which, by reducing the number of shares
            outstanding, increases the proportionate number of
            shares beneficially owned by such Person to 10% or
            more of the shares of Common Stock of the Company
            then outstanding; unless and until such time as such
            Person shall purchase or otherwise become (as a
            result of actions taken by such Person or its Affil-
            iates or Associates) the Beneficial Owner of addi-
            tional shares of Common Stock constituting 1% or
            more of the then outstanding shares of Common Stock
            other than pursuant to a Qualifying Offer (as de-
            fined below) and (ii) "Acquiring Person" shall not
            include any Person while such Person is entitled to
            report such ownership (but less than 15%) on Sched-
            ule 13G under the Exchange Act (as defined below)
            (or any comparable or successor report) and does not
            state any intention to or reserve the right to
            change or influence the control of the Company or
            engage in any of the actions specified in Item 4 of
            Schedule 13D (or any successor form) under the
            Exchange Act (as defined below) (other than the
            disposition of Common Stock) and either (A) was the
            Beneficial Owner on May 6, 1997 of 10% or more of
            the outstanding shares of Common Stock and does not
            at any time become the Beneficial Owner of 15% or
            more of the outstanding shares of Common Stock or
            (B) within 10 Business Days of being requested by
            the Company to advise it regarding the same, certi-
            fies to the Company that such Person acquired shares
            of Common Stock in excess of 9.99% inadvertently or
            without knowledge of the terms of the Rights and
            who, together with all Affiliates and Associates,
            thereafter does not acquire additional shares of
            Common Stock while the Beneficial Owner of 10% or
            more of the shares of Common Stock then outstanding
            and within 10 Business Days of being requested by
            the Company to do so disposes of the portion of such
            Common Stock in excess of 9.99%; provided, however,
            that if the Person requested to so certify fails to
            do so within 10 Business Days of the Company's
            request or such Person fails to dispose of such
            Common Stock in excess of 9.99% within 10 Business
            Days of the Company's request, then such Person
            shall become an Acquiring Person immediately after
            such 10 Business Day period."
     
               2.   Pursuant to Section 26 of the Rights
     Agreement, Section 11(a)(ii) of the Rights Agreement is
     hereby amended to read in its entirety as follows:
     
            "(ii)  In the event any Person shall become an
            Acquiring Person, unless the event causing the
            Person to become an Acquiring Person is a trans-
            action set forth in Section 13(a) hereof, or is an
            acquisition of shares of Common Stock pursuant to a
            tender offer or an exchange offer for all outstand-
            ing shares of Common Stock at a price and on terms
            determined by at least a majority of the Continuing
            Directors who are not officers of the Company, after
            receiving advice from one or more nationally recog-
            nized investment banking firms, to be (a) at a price
            which is fair to stockholders (taking into account
            all factors which such members of the Board deem
            relevant including, without limitation, prices which
            could reasonably be achieved if the Company or its
            assets were sold on an orderly basis designed to
            realize maximum value) and (b) otherwise in the best
            interests of the Company and its stockholders (a
            "Qualifying Offer"), then, promptly following the
            first occurrence of a Section 11(a)(ii) Event,
            proper provision shall be made so that each holder
            of a Right (except as provided below and in Section
            7(e) hereof) shall thereafter have the right to
            receive, upon exercise thereof at the then current
            Purchase Price in accordance with the terms of this
            Agreement, in lieu of a number of one one-hundredths
            of a share of Preferred Stock, such number of shares
            of Common Stock of the Company as shall equal the
            result obtained by (x) multiplying the then current
            Purchase Price by the then number of one one-hun-
            dredths of a share of Preferred Stock for which a
            Right was exercisable immediately prior to the first
            occurrence of a Section 11(a)(ii) Event, and (y)
            dividing that product (which, following such first
            occurrence, shall thereafter be referred to as the
            "Purchase Price" for each Right and for all purposes
            of this Agreement) by 50% of the current market
            price (determined pursuant to Section 11(d) hereof)
            per share of Common Stock on any Trading Day (as
            defined in Section 11(d) hereof) occurring within
            the 12 month period immediately preceding the date
            of such first occurrence (such number of shares, the
            "Adjustment Shares")."
     
               3.   Pursuant to Section 26 of the Rights
     Agreement, Section 13(a) of the Rights Agreement is
     hereby amended by (i) deleting, following the word "that"
     in the first line thereof, the phrase ", following the
     Stock Acquisition Date" and (ii) by inserting as a new
     sentence following the final sentence thereof the follow-
     ing: 
     
             "Notwithstanding anything in this Agree-
              ment to the contrary, if a Section 13
              Event shall occur prior to the Distribu-
              tion Date, then (i) the Rights shall sur-
              vive such Section 13 Event and shall not
              as a result thereof be cancelled, termi-
              nated or otherwise cease to exist and
              (ii) the Distribution Date shall be
              deemed to have occurred on the day
              immediately prior to the date of such
              Section 13 Event."
     
               4.   Pursuant to Section 26 of the Rights
     Agreement, Section 13(d) of the Rights Agreement is
     hereby amended by deleting the words "tender offer or
     exchange offer for all outstanding shares of Common Stock
     which complies with the provisions of Section 11(a)(ii)
     hereof" and inserting in lieu thereof the term "Qualify-
     ing Offer".
     
               5.   Pursuant to Section 26 of the Rights
     Agreement, Section 23 of the Rights Agreement is hereby
     amended by deleting the words "cash tender pursuant to a
     Schedule 14D-1 (or any successor form) filed with the
     Securities and Exchange Commission for all outstanding
     shares of Common Stock not owned by such person or its
     Affiliates of Associates" and inserting in lieu thereof
     the term "Qualifying Offer".
     
               6.   Pursuant to Section 26 of the Rights
     Agreement, Section 25 of the Rights Agreement is hereby
     amended by replacing the name and address of NCNB Texas
     National Bank set forth therein with the following:
     
               "The Bank of New York
               101 Barclay Street
               New York,  New York  10286
               Attention:  Corporate Trust Department."
     
               7.   Pursuant to Section 26 of the Rights
     Agreement, Section 26 of the Rights Agreement is hereby
     amended (i) by deleting the parenthetical language in the
     second sentence thereof and (ii) by inserting immediately
     following the second sentence thereof the following:
     
               "Notwithstanding anything in this Agree-
                ment to the contrary, no amendment, wheth-
                er before or after the Distribution Date,
                shall be made following the first occur-
                rence of an event specified in clauses (x)
                or (y) of the first proviso to Section
                23(a) hereof, unless there are Continuing
                Directors and a majority of such Continu-
                ing Directors concur in such amendment."
     
               8.   This Amendment No. 1 may be executed in
     any number of counterparts and each of such counterparts
     shall for all purposes be deemed to be an original and
     all such counterparts shall together constitute but one
     and the same instrument.  Terms not defined herein shall,
     unless the context otherwise requires, have the meanings
     assigned to such terms in the Rights Agreement.
     
               9.   The amendments set forth herein are limit-
     ed precisely as written and shall not be deemed to be an
     amendment to any other provision contained in the Rights
     Agreement.  In all respects not inconsistent with the
     terms and provisions of this Amendment No. 1, the Rights
     Agreement is hereby ratified and confirmed.  In executing
