GENERAL
--------------------------------------------------------------------------------

We have sent you this booklet and proxy on or about April 18, 2003 because the
Board of Directors of Westinghouse Air Brake Technologies Corporation, doing
business as Wabtec, is soliciting your proxy to vote at the company's 2003
annual meeting of stockholders.

WHO MAY VOTE

Stockholders of Wabtec as reflected in our stock records at the close of
business on March 24, 2003 may vote. You have one vote for each share of Wabtec
common stock you own.

HOW TO VOTE

You may vote in person at the meeting or by proxy. Most shareholders of record
have a choice of voting by proxy over the Internet, by telephone, or by using a
traditional proxy card. Please check your proxy card or the information
forwarded by your bank, stockbroker or other holder of record to see which
options are available to you. We recommend you vote by proxy even if you plan to
attend the meeting. You can always change your vote at the meeting.

ELECTRONIC ACCESS TO PROXY MATERIALS AND ANNUAL REPORT

This notice of Annual Meeting and Proxy Statement and the 2003 Annual Report are
available on our Internet site at http//www.wabtec.com. If you are a shareholder
of record and would like to view future proxy statements and annual reports over
the Internet instead of receiving copies in the mail, follow the instructions
provided when you vote over the Internet or by telephone, or check the
appropriate box on the proxy card if mailing your proxy. If you hold your shares
through a bank, stockbroker or other holder, check the information provided by
that entity for instructions on how to view future proxy statements and annual
reports and vote your shares over the Internet. Choosing to receive your proxy
materials online saves us the cost of producing and mailing these materials to
your home or office and gives you an automatic link to the proxy voting site.

HOW A PROXY WORKS

Giving us a proxy means you authorize us to vote your shares in accordance with
your directions. If you do not make any selections, your shares will be voted in
favor of our director candidates and ratification of the independent public
accountants.

You may receive more than one proxy or voting card depending on how you hold
your shares. Shares registered in your name are generally covered by one card.
If you hold shares through someone else, such as a stockbroker, you may get
material from them asking how you want to vote.

CHANGING YOUR VOTE

You may revoke your proxy before it is voted by submitting a new proxy with a
later date, by voting in person at the meeting or by notifying Wabtec's
Secretary in writing.

COMMON STOCK OUTSTANDING

As of the close of business on March 24, 2003, 43,449,249 shares of Wabtec
common stock were issued and outstanding.

QUORUM AND VOTING INFORMATION

In order to conduct the business of the meeting, we must have a quorum. This
means at least a majority of the outstanding shares eligible to vote must be
represented at the meeting, either in person or by proxy. You are considered a
part of the quorum if you submit a properly signed proxy card, vote over the
Internet or vote by telephone.

If a quorum is present at the meeting, the three director candidates receiving
the most votes will be elected to fill the three open seats on the Board.
Ratification of the appointment of the independent public accountants requires
the favorable vote of a majority of the shares present in person or by proxy.
Approval of any other matter that properly comes before the Board requires the
favorable vote of a majority of shares present in person or by proxy, unless the
matter requires more than a majority vote under statute or our bylaws.

Because the total shares voted "for," "against," or "abstain" are counted to
determine the minimum votes required for approval, if you abstain from

                                       -1-


voting, it has the same legal effect as a vote against. If a broker limits the
number of shares voted on the proposal on its proxy card or indicates that the
shares represented by the proxy card are not being voted on the proposal, it is
considered a broker non-vote. Broker non-votes are not counted as a vote or used
to determine the favorable votes required to approve the proposal.

COMMON STOCK OWNERSHIP

DIRECTOR AND EXECUTIVE OFFICER STOCK OWNERSHIP

PROPOSAL 1 -- ELECT DIRECTORS
--------------------------------------------------------------------------------

Wabtec's Board of Directors currently has eight members and four vacant seats.
The board is divided into three classes whose terms of office end in successive
years. Robert J. Brooks resigned his position in the class of directors whose
term expires in 2003. Mr. Brooks was then appointed by the Board to fill a
vacancy in the class of directors whose term expires in 2004. Gregory T. H.
Davies and Kim G. Davis, whose terms of office are expiring, have been nominated
to serve for new terms ending in 2006. Michael W. D. Howell has been nominated
to serve as a director for a term of office expiring in 2006 in the vacancy
created by Mr. Brooks. The board may act at a future date to fill the three
remaining vacancies or reduce the size of the board. The nominations were made
by the Nominating Committee of the Board and approved by the Board. The
Nominating Committee has the sole authority to make the nominations and met two
times in 2002. The members of the Nominating Committee are Mr. Davies and Mr.
Kassling.

Your proxy will be voted FOR the election of these nominees unless you withhold
authority to vote for any one or more of them. If any nominee is unable or
unwilling to stand for election, your proxy authorizes us to vote for a
replacement nominee if the board names one.

Only votes for a candidate are counted in the election of directors. The three
nominees who receive the most votes will be elected as directors.

THE BOARD RECOMMENDS YOU VOTE FOR EACH OF THE FOLLOWING CANDIDATES.

DIRECTORS' COMPENSATION

Wabtec's non-employee director compensation plan pays each director who is not
an employee of the company a cash retainer of $10,000 per year for his services
as a director. In addition, each such director is entitled to receive $1,000 for
each meeting of the Board attended in person, and $1,000 per Board committee
meeting. Non-employee directors receive $500 for participating in a Board or a
committee meeting by telephone. All directors are reimbursed for their
out-of-pocket expenses incurred in connection with attendance at meetings and
other activities relating to the Board or Board Committee.

In addition, the non-employee directors also participate in the 1995
Non-Employee Directors' Fee and Stock Option Plan to encourage the highest level
of performance for members of the Board of Directors by providing such directors
with a proprietary interest in the Company's financial success. Under the Plan,
each non-employee director is entitled to receive 1,000 shares of

                                       -5-


common stock annually. In addition, all non-employee directors as of January 25,
2000 received a one time initial grant of 5,000 stock options (priced at $12.75
with a vesting period of three years), received 5,000 stock options on December
5, 2000 (priced at $9.535 with a vesting period of three years) and will receive
2,000 stock options each January 2 during their term of service on the Board.
Such grants will be priced at the average of the high and low stock price on the
day granted, with a vesting period of three years. These grants commenced in
January 2002. Newly elected directors are eligible to receive 5,000 stock
options upon their initial election to the Board.

THE BOARD AND COMMITTEES

The Board met five times during 2002. All directors attended at least 75% of all
meetings of the Board and the Committees on which they served in 2002. The Board
committees that help the Board fulfill its duties include the Nominating
Committee, the Audit Committee and the Compensation Committee.

THE AUDIT COMMITTEE

The Audit Committee acts under a written charter which was amended and restated
by the Board of Directors on February 20, 2002. The Audit Committee provides
assistance to the Board in fulfilling their oversight responsibility to
stockholders, potential stockholders, the investment community and others
relating to Wabtec's financial statements and the financial reporting process,
the systems of internal accounting and financial controls, the internal audit
function, the annual independent audit of Wabtec's financial statements, and the
legal compliance and ethics programs as established by management and the Board.
The Audit Committee met six times in 2002. The Audit Committee members are Mr.
Davis, Mr. Fernandez and Mr. Miscoll. The Board of Directors, in its business
judgment, has concluded that all Audit Committee members are independent as
defined by the New York Stock Exchange listing standards.

AUDIT COMMITTEE REPORT

The audit committee is responsible for reviewing the Company's financial
reporting process on behalf of the Board of Directors. Management of the Company
has the primary responsibility for the financial statements and the reporting
process, including the system of internal controls. In the performance of our
oversight function, we meet with management periodically to consider the
adequacy of the Company's internal controls and the objectivity of its financial
reporting. We meet privately with the independent public accountants, who have
unrestricted access to the audit committee. Specifically, we have reviewed and
discussed with management and the independent public accountants the Company's
consolidated financial statements as of and for the fiscal year ended December
31, 2002.

We have also discussed with the independent public accountants the matters
required to be discussed by Statement on Auditing Standards No. 61,
Communication with Audit Committees, as currently in effect.

Furthermore, we have received and reviewed the written disclosures and the
letter from the independent public accountants required by Independence
Standards Board Standard No. 1, Independence Discussions with Audit Committees,
as currently in effect, and have discussed with the independent public
accountants their independence.

Based on the review and discussions referred to above, we recommended to the
Board of Directors that the audited financial statements referred to above be
included in the Company's Annual Report on Form 10-K for the year ended December
31, 2002 to be filed with the Securities and Exchange Commission.

As part of the ongoing oversight process, the Audit Committee has been closely
monitoring the significant regulatory activities of the SEC and the NYSE during
the 2002 fiscal year. In order to ensure compliance with all of the new and
pending rules and regulations, the Audit Committee has sought and received the
advice of legal counsel and the advice of its independent public accountants.
The Audit Committee has reviewed its existing charter, policies and procedures
and is positioning itself to timely adopt and implement considered and
functional policies and procedures, and to update its charter accordingly.

Respectfully submitted,

James P. Miscoll, Chairman
Kim G. Davis
Emilio A. Fernandez

(1) The option grants were made on January 7, 2002 under the Wabtec Stock
    Incentive Plan.

(2) Based on the Black-Scholes option pricing model adopted for use in valuing
    executive stock options. The actual value, if any, an executive may realize
    will depend on the excess of the stock price over the exercise price on the
    date the option is exercised. There is no assurance that the value realized
    by an executive will be at or near the value estimated by the Black-Scholes
    model. The estimated values under that model were calculated based on the
    following Assumptions:



                                                                  JANUARY 7, 2002

COMPENSATION COMMITTEE REPORT

Even if Wabtec's previous filings under the Securities Laws incorporate future
filings, including proxy statements, the following report and the Stock
Performance Graph on page 11 are NOT incorporated by reference into any of those
previous filings.

All of the members of the Compensation Committee are non-employee directors. The
committee's principal responsibility is to review, recommend and approve changes
to our compensation policies and programs. The committee is also responsible for
reviewing and approving all compensation actions for the Chief Executive Officer
and other executive officers.

Our compensation plan has three basic components:

     - base salaries and bonuses,

     - benefit plans, and

     - long-term incentives.

BASE SALARIES AND BONUSES.  The committee recommends base salaries and bonuses
of executive officers to the board, which then establishes these items. Base
salaries are determined at the beginning of the year and bonuses are awarded
after our fiscal year results are available.

Executive officers' base salaries depend mainly on their office and
responsibilities and are reviewed annually. Mr. Davies serves as Chief Executive
Officer of Wabtec. The committee reviews and approves Mr. Davies' salary each
year. As Chief Executive Officer, Mr. Davies' annual base salary is $615,000.
Mr. Davies also receives a bonus based on the same factors as the other
Executive Officers as discussed below.

During 2002, Wabtec had in effect an executive bonus plan, which had been
approved by the Board. Bonuses are based upon the success of two factors: a
financial performance factor, which measures (i) earnings before interest and
taxes and (ii) working capital; and a personal performance factor which measures
whether the executive has attained certain goals agreed to by the executive, his
supervisor, and the Board. There are guidelines as to the payment of bonuses,
although the Committee may exercise its discretion with respect to those
guidelines. We believe this philosophy encourages Wabtec and our executives to
establish ambitious goals and promotes teamwork, productivity and profitability.

Wabtec's employees may purchase shares of Wabtec common stock under the 1998
Employee Stock Purchase Plan. The plan allows eligible employees to purchase
shares of Wabtec common stock for 85% of fair market value through payroll
deductions. We believe that this plan promotes Wabtec's continued success by
encouraging our employees to have increased awareness of, and commitment to, our
corporate-wide goals. Messrs. Kassling, Davies, Brooks and Golden participated
in this plan during 2002. They purchased shares of common stock with a total
fair market value, when purchased, of $21,416, $22,138, $21,043 and $10,368
respectively.

                                       -9-


LONG-TERM INCENTIVES.  The committee may grant long-term incentives to employees
by granting stock options and making restricted share awards under the 2000
Stock Incentive Plan. The committee views stock options and restricted share
awards as incentives to enable Wabtec to hire and retain executives and to
provide executives with incentives related to the Company's stock price so they
have interests similar to your interests as Wabtec common stockholders. Our
decision to grant stock options or award restricted shares is based upon an
individual's job level, among other factors.

OTHER.  Executive officers also may participate in Wabtec's 401(k) Plan. Wabtec
provides certain other personal benefits to certain employees, including
executive officers, that are not significant in total.

Respectfully submitted,

James V. Napier, Chairman
Emilio A. Fernandez
Lee B. Foster

PROPOSAL 2 -- RATIFY INDEPENDENT ACCOUNTANTS
--------------------------------------------------------------------------------

On May 30, 2002, we dismissed Arthur Andersen, LLP as Wabtec's independent
public accountants, and, after a review of several possible candidates,
appointed Ernst & Young, LLP to serve as Wabtec's independent public accountants
for fiscal year 2002, in accordance with the recommendation of Wabtec's Board of
Directors and its Audit Committee. The company dismissed Arthur Andersen, LLP as
its auditor because it believed that the firm could no longer provide the
necessary services on a global basis.

Arthur Andersen's reports on Wabtec's financial statements for each of the
fiscal years, ended December 31, 2000, and December 31, 2001, did not contain an
adverse opinion or disclaimer of opinion, nor were such reports qualified or
modified as to uncertainty, audit scope or accounting principles.

During the fiscal years, ended December 31, 2000, and December 31, 2001, and
through the date of their dismissal, there were no disagreements with Arthur
Andersen on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure which, if not resolved to
Arthur Andersen's satisfaction would have caused them to make reference to the
subject matter of the disagreement in connection with the audit reports of
Wabtec's consolidated financial statements for such years. There were no
reportable events as described under Item 304(a) (i) (v) of Regulation S-K.

During each of the fiscal years, ended December 31, 2000 and December 31, 2001,
and through the date hereof, Wabtec did not consult Ernst & Young with respect
to the application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
our financial statements, or any other matters or reportable events as set forth
in Items 304 (a) (2) (i) and (ii) of Regulation S-K.

We have provided both Arthur Andersen and Ernst & Young with a copy of this
disclosure.

On February 19, 2003, our Board of Directors approved the Audit Committee's
recommendation that Ernst & Young be appointed to audit our financial statements
for 2003. Although you are not required to ratify this appointment, we ask that
you do. If you do not, we will reconsider our choice. A representative of Ernst
& Young will be at the meeting to answer appropriate questions and make a
statement if they desire.

This proposal is adopted if a majority of the shares present in person or by
proxy vote for the proposal. Because the total shares voted "for," "against," or
"abstain" are counted to determine the minimum votes required for approval, if
you abstain from voting, it has the same legal effect as if you vote against. If
a broker limits the number of shares voted on the proposal on its proxy card or
indicates that the shares represented by the proxy card are not being voted on
the proposal, it is considered a broker non-vote. Broker non-votes are not
counted as a vote or used to determine the favorable votes required to approve
the proposal.

THE BOARD RECOMMENDS YOU VOTE FOR THIS PROPOSAL.

AUDIT FEES

Wabtec was billed $450,886 in aggregate fees by the independent public
accountants for the professional services rendered for the audit of Wabtec's
financial statements for the year ended December 31, 2002, and the reviews of
its financial statements included in its Forms 10-Q for the 2002 fiscal year.

FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

The independent public accountants did not bill Wabtec for any financial
information systems design and implementation fees for services rendered during
2002.

ALL OTHER FEES

In addition to the audit fees described above, the independent public
accountants billed Wabtec approximately $161,845 for other audit and
accounting-related services and $165,665 for tax outsourcing and compliance
(which includes the review of annual tax returns) for the 2002 fiscal year.

                                       -12-


OTHER INFORMATION
--------------------------------------------------------------------------------

We do not expect any business to come before the meeting other than the election
of directors and the ratification of the independent public accountants. If
other business is properly raised, your proxy authorizes its holder to vote
according to their best judgment.

EXPENSES OF SOLICITATION

Wabtec pays the cost for proxy solicitation. In addition to mailing, officers
and employees may solicit proxies in person, by telephone or telegraph. Wabtec
will pay about $15,000 to Mellon Investor Services, LLC, for sending the proxy
material and the 2002 Annual Report to stockholders. We will also reimburse
other nominees, custodians or fiduciaries who forward these materials to
stockholders for their expenses in doing so.

STOCKHOLDER PROPOSALS FOR NEXT YEAR

To be eligible for inclusion in next year's proxy for the 2004 annual meeting,
the deadline for stockholder proposals is December 19, 2003. Additionally, our
advance notice provision in our by-laws requires that for business to otherwise
be properly brought before the annual meeting, notice must be submitted to us
between December 19, 2003 and February 18, 2004.

By order of the Board of Directors,
