Re: 	American Railcar Industries, Inc.
	Registration Statement on Form S-1
	Filed December 13, 2005
	File No. 333-130284

Dear Mr. Unger,

      We have reviewed your filing and have the following
comments.
Where indicated, we think you should revise your document in
response
to these comments.  If you disagree, we will consider your
explanation as to why our comment is inapplicable or a revision is
unnecessary.  Please be as detailed as necessary in your
explanation.
In some of our comments, we may ask you to provide us with
supplemental information so we may better understand your
disclosure.
After reviewing this information, we may or may not raise
additional
comments.  Page references are to the marked copy you provided.

Ohio Castings, LLC and Subsidiaries
Consolidated Statements of Cash Flows, page F-56
1. It appears your line item description, "Decrease in cash and
cash
equivalents," on the face of your statements of cash flows is
incorrect as cash flows from operating, investing and financing
activities indicate cash and cash equivalents increased in all
periods presented.  Please revise accordingly.

Debt Issuance Costs, page F-59
2. It appears that accumulated amortization of $54 at August 31,
2005
should be $64 based on amortization expense of $24 and $40 for the
years ended August 31, 2004 and 2005, respectively.  Please advise
or
revise accordingly.
Impairment of Long-Lived Assets, page  F-60
3. The disclosure indicating "if the carrying amount of an asset
is
less than the future undiscounted cash flows expected to be
generated
by the asset, the impairment to be recognized is measured by the
amount by which the carrying amount of the asset exceeds the fair
value" appears to be in error.  Note that paragraph 7 of SFAS No.
144
provides for an impairment charge to be recognized when the
carrying
amount of a long-lived asset exceeds the sum of the undiscounted
cash
flows expected to result from the use and eventual disposition of
the
asset.  Please revise your accounting policy disclosures relative
to
impairments of long-lived assets to comply with SFAS No.144.

Exhibit 23.2 Consent of Independent Registered Public Accounting
Firm
4. Please obtain a revised consent from Grant Thornton which
refers
to their audit report of Ohio Castings Company LLC dated December
1,
2005 rather than December 9, 2005.
