                  Re:   Registration Statement on Form S-8
                        ----------------------------------

Gentlemen and Ladies:

                  We have acted as special counsel to Westinghouse Air Brake
Company (the "Company") in connection with the preparation of a Registration
Statement on Form S-8 (the "Registration Statement") under the Securities Act of
1933, as amended (the "Act") relating to up to 1,600,000 shares of the Company's
Common Stock, par value $.01 per share, (the "Common Stock") which may be
purchased by or awarded to employees of the Company pursuant to stock options
granted or restricted shares or performance units awarded under the Company's
1995 Stock Incentive Plan (the "Plan"). The Plan provides that either authorized
but unissued or treasury shares of Common Stock may be issued under the Plan. In
rendering our opinion below, we have assumed that any previously issued shares
reacquired by the Company and used under the Plan will have been duly
authorized, validly issued and fully paid at the time of their original
issuance.

                  In connection with this opinion, we have examined, among other
things:

                  (1) the Restated Certificate of Incorporation of the Company,
         as amended to date;

                  (2) resolutions adopted by the Board of Directors of the
         Company on May 26, 1995 adopting the Plan, on July 29, 1997 adopting
         certain amendments to the Plan and on February 26, 1998 authorizing the
         issuance of an additional 1,600,000 shares of Common Stock to be
         reserved for issuance under the Plan; and

                  (3) the Plan, as currently in effect.

                  Based upon the foregoing and upon an examination of such other
documents, corporate proceedings, statutes, decisions and questions of law as we
considered necessary in order to enable us to furnish this opinion, and subject
to the assumptions set forth above, we are pleased to advise you that in our
opinion:

                  (a) The Company has been duly incorporated and is a validly
         existing corporation under the laws of the State of Delaware; and

                  (b) The shares of Common Stock being registered and which may
         be issued by the Company pursuant to the provisions of the Plan have
         been duly authorized, and upon such issuance in accordance with the
         provisions of the Plan such shares will be validly issued, fully paid
         and nonassessable.

                  We hereby consent to the filing of this opinion as Exhibit
5.1, to the Registration Statement. In giving such consent, we do not admit that
we are in the category of persons whose consent is required under Section 7 of
the Act.

                                         Yours truly,

                                         /s/ Reed Smith Shaw & McClay LLP
