Re:       Registration Statement on Form S-3

Ladies and Gentlemen:

We have served as special Nevada counsel to Westinghouse Air Brake Technologies Corporation, a Delaware corporation (the “Company”), and Transportation Systems Services Operations Inc., a Nevada corporation (the “Nevada Subsidiary Guarantor”), in connection with the filing by the Company of a Registration Statement on Form S-3 (the “Registration Statement”) with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), relating to (i) the registration for offering and sale from time to time, on a delayed basis, by the Company of an indeterminate number of securities identified in the Registration Statement, including debt securities (the “Debt Securities”) issuable under (a) the Indenture, dated as of August 8, 2013, by and between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as trustee, which is included as Exhibit 4.1 to the Registration Statement, as supplemented to date by any supplemental indenture included as an exhibit to the Registration Statement (the “Base Indenture”), (b) a senior debt indenture in the form of senior debt indenture included as Exhibit 4.21 to the Registration Statement (each a “Senior Debt Indenture”) or (c) a subordinated debt indenture in the form of subordinated debt indenture included as Exhibit 4.23 to the Registration Statement (each a “Subordinated Debt Indenture” and each of the Base Indenture, the Senior Debt Indenture and the Subordinated Debt Indenture, an “Indenture”), in each case as such indenture may hereafter be supplemented from time to time, among other things at the time of and in connection with the issuance of such Debt Securities, and (ii) the registration by the co-registrants identified in the Registration Statement, including the Nevada Subsidiary Guarantor, of guarantees of the Debt Securities (collectively, the “Subsidiary Guarantees” and, together with the Debt Securities, the “Securities”) issuable under one or more supplements to the Indenture. The Securities may be offered and sold from time to time pursuant to Rule 415 under the Act.

In our capacity as such counsel, we are familiar with the proceedings taken and proposed to be taken by the Company and the Nevada Subsidiary Guarantor in connection with the registration of the Subsidiary Guarantees, as described in the Registration Statement. For purposes of this opinion letter, and except to the extent set forth in the opinions below, we have assumed all such proceedings have been timely completed or will be timely completed in the manner presently proposed in the Registration Statement.
