                                  SCHEDULE 13D

Item 1. Security and Issuer

     The  Schedule 13D filed with the  Securities  and  Exchange  Commission  on
January 25, 2008 by the Reporting  Persons (the  "Initial  13D") with respect to
the Common Stock,  without par value (the  "Shares"),  issued by The  Greenbrier
Companies,  Inc.  (the  "Issuer")  and as amended by  amendment  Number 1 to the
Initial 13D filed on June 11, 2008 ("Amendment Number 1"), amendment Number 2 to
the Initial 13D filed on June 19, 2008 ("Amendment  Number 2"), amendment Number
3 to the Initial 13D filed on July 14, 2008 ("Amendment  Number 3", and together
with Amendment  Number 1, Amendment  Number 2 and the Initial 13D, the "Schedule
13D") is hereby amended to furnish the additional  information set forth herein.
All capitalized  terms contained herein but not otherwise defined shall have the
meanings ascribed to such terms in the Initial 13D.

Item 5. Interest in Securities of the Issuer

     Item 5 of the  Schedule 13D is hereby  amended by  replacing  Item 5 in its
entirety with the following:

          (a) The Reporting  Persons may be deemed to  beneficially  own, in the
     aggregate, 817,515 Shares, representing approximately 4.92% of the Issuer's
     outstanding   Shares  (based  upon  the  16,606,250  Shares  stated  to  be
     outstanding as of June 30, 2008 by the Issuer in the Issuer's Form 10-Q for
     the quarter  ended May 31,  2008,  filed with the  Securities  and Exchange
     Commission).

          (b)  Longtrain has sole voting power and sole  dispositive  power with
     regard to 817,515  Shares.  Each of ARI,  Hopper,  Modal,  Barberry and Mr.
     Icahn has shared voting power and shared  dispositive  power with regard to
     such Shares.

          Each of ARI, Hopper, Modal, Barberry and Mr. Icahn, by virtue of their
     relationships to Longtrain (as disclosed in Item 2 of the Initial 13D), may
     be deemed to indirectly  beneficially  own (as that term is defined in Rule
     13d-3 under the Act) the Shares which Longtrain directly beneficially owns.
     Each of ARI,  Hopper,  Modal,  Barberry and Mr. Icahn disclaims  beneficial
     ownership of such Shares for all other purposes.

          (c) The following  table sets forth all  transactions  with respect to
     Shares  effected  during the past  sixty (60) days by any of the  Reporting
     Persons.  Except as otherwise indicated,  all transactions were effected in
     the open  market,  and the  table  includes  commissions  paid in per share
     prices.
