                                  SCHEDULE 13D

Item 1. Security and Issuer

     The  Schedule 13D filed with the  Securities  and  Exchange  Commission  on
January 31, 2006 by the  Registrants  (the "Initial  13D"),  with respect to the
shares of Common Stock,  par value $0.01 per share (the  "Shares"),  of American
Railcar  Industries,  Inc., a Delaware  corporation  (the  "Issuer"),  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 Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration

     Item 3 of the Initial 13D is hereby amended and restated in its entirety as
follows:

     On January 19, 2006, the Issuer's Registration  Statement on Form S-1 (File
No. 333-130284) and Registration Statement on Form 8-A (File No. 000-51728) were
declared  effective by the Securities and Exchange  Commission  (the  "Effective
Date").  All of the  Registrants,  except Modal and Ms.  Golden,  acquired their
respective Shares prior to the Effective Date.

     On January 20, 2006,  pursuant to a stock  purchase  agreement  (the "Stock
Purchase  Agreement"),  dated December 7, 2005, among Modal,  High Coast Limited
Partnership,  a Delaware limited  partnership  ("High Coast") and The Foundation
for  a  Greater  Opportunity,   a  Delaware   not-for-profit   corporation  (the
"Foundation"),  Modal  purchased  4,290,918  Shares  from  the  Foundation.  The
aggregate  purchase  price for such  Shares  was  $100,000,000.  Modal  paid the
purchase  price  with  $10,000,000  in  cash  and  the  balance  in a  five-year
interest-only secured promissory note. The source of funding for the purchase of
these Shares was the general working capital of Modal.

     On January 24, 2006, in connection with the closing of the Issuer's initial
public  offering,  Ms. Golden  purchased  23,800 Shares through a directed share
program that was offered by the Issuer.  The aggregate  purchase price for these
Shares was $499,800.  The source of funding for the purchase of these Shares was
Ms. Golden's personal funds.

     From November 13, 2007 to November 19, 2007,  Hopper purchased an aggregate
of 304,616 Shares in the open market for  $4,607,842.  The source of funding for
the purchase of these shares was the general working capital of Hopper.

Item 5. Interest in Securities of the Issuer

          (a) As of 4:00 pm,  Eastern  Standard  Time,  on  November  19,  2007,
     Registrants may be deemed to beneficially own, in the aggregate, 11,475,475
     Shares, representing approximately 53.9% of the Issuer's outstanding Shares
     (based upon  21,302,296  Shares stated to be  outstanding  by the Issuer in
     Form 10-Q filed by the Issuer on November 8, 2007).

          (b)  Hopper  has sole  voting  power and sole  dispositive  power with

     sole voting power and sole dispositive  power with regard to 23,800 Shares.

     power with regard to such Shares.  Mr. Icahn has sole voting power and sole
     dispositive power with regard to 5,037,165 Shares.

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

     disclaims beneficial ownership of such Shares for all other purposes.

          (c) The following  table sets forth all  transactions  with respect to
