REPORT OF INDEPENDENT PUBLIC AUDITORS

To the Westinghouse Air Brake Technologies Corporation Savings Plan for Hourly
Employees and Participants:

We have audited the accompanying statement of net assets available for benefits
of the Westinghouse Air Brake Technologies Corporation Savings Plan for Hourly
Employees as of December 31, 2001 and the related statement of changes in net
assets available for benefits for the year then ended. These financial
statements are the responsibility of the Plan's management. Our responsibility
is to express an opinion on these financial statements and schedule based on our
audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 2001, and the changes in its net assets available for benefits for
the year then ended, in conformity with accounting principles generally accepted
in the United States.

Our audit was made for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying schedule of assets held at end of
year is presented for purposes of additional analysis and is not a required part
of the basic financial statements but is supplementary information required by
the Department of Labor's Rules and Regulations for Reporting and Disclosure
under the Employee Retirement Income Security Act of 1974. The supplemental
schedule has been subjected to the auditing procedures applied in the audit of
the financial statements and, in our opinion, is fairly stated in all material
respects in relation to the financial statements taken as a whole.

1. DESCRIPTION OF PLAN:
   --------------------

The following brief description of the Plan is provided for general information
purposes only. Participants should refer to the Plan document for more complete
information.

General
-------

The Westinghouse Air Brake Technologies Corporation Savings Plan for Hourly
Employees (the Plan), effective May 1, 1999, is a contributory plan intended to
comply with the provisions of Sections 401(a), 401(k), and 401(m) of the
Internal Revenue Code (IRC).

Contributions
-------------

Participants may contribute, through payroll deductions, employee elective
contributions from 1% to 16% of their compensation each Plan year, limited to
$10,500 in 2001. In addition, participants may contribute employee after tax
contributions from 1% to 16% of their compensation each Plan year.

Participant total annual contributions may not exceed the contribution limits
under Section 415(c) of the IRC. In addition, the combination of an employee's
elective contribution and after tax contribution cannot exceed 16% of his/her
compensation.

Withdrawals
-----------

Participants may make the following types of withdrawals:

     IN-SERVICE WITHDRAWALS--A participant may withdraw any amount of the vested
     portion of his/her employer matching account, employer after-tax account,
     and rollover accounts once in any six-month period. Once a participant has
     reached age 59-1/2, he/she can withdraw any portion of his/her employee
     elective account.

     HARDSHIP WITHDRAWALS--In the case of hardship, as defined in the Plan
     document, the participant can receive 100% of his/her employee elective
     account. Hardship withdrawals are limited to once every Plan year.

Loans
-----

Participants may receive loans from the Plan. At no time shall the loans of the
participant exceed the lesser of: 50% of the value of the participant's vested
balance of his/her accounts, reduced by any outstanding loan balance or $50,000.

Vesting

Employee contributions are at all times 100% vested and nonforfeitable.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
   -------------------------------------------

Basis of Accounting
-------------------

The accounts of the Plan are maintained on the accrual basis of accounting.
Expenses incurred by the plan administrator, investment manager and trustee for
their services and costs in administering the Plan are paid directly by the
Company.


                                       5


Investment Options
------------------

The trustee of the investments is Fidelity Management Trust Company (Fidelity)
per the Trust Agreement dated May 1, 1999. Fidelity maintains the investments
and provides record-keeping functions for the Plan. Each participant's account,
at the discretion of the participant, may be invested in any of the following
funds:

a. FIDELITY EQUITY INCOME FUND--This fund invests approximately 80% of its
portfolio in common and preferred stocks and 20% in debt securities, usually
those convertible to common stock. The goal of this fund is to provide dividends
as well as price appreciation.

b. FIDELITY GROWTH COMPANY FUND--This fund invests in securities of companies
with above average growth characteristics as demonstrated in earnings or gross
sales. These securities include common stocks, securities convertible into
common stocks and occasionally debt obligations.

c. FIDELITY OVERSEAS FUND--This fund normally invests at least 65% of the fund's
total assets in securities of issuers from at least three countries outside the
United States. These securities include common stocks, securities convertible to
common stocks and debt instruments of foreign businesses and governments.

d. FIDELITY BLUE CHIP GROWTH FUND--This fund invests primarily in a diversified
portfolio of common stocks of well-known and established companies. Normally, at
least 65% of these securities are issued by "blue chip" companies. A blue chip
firm can generally be described as having a market value of at least $200
million in outstanding stock. Its securities usually are included in the
Standard & Poor's Composite Stock Price Index of 500 common stocks or the Dow
Jones Industrial Average. This fund seeks growth of capital over the long term.

e. FIDELITY ASSET MANAGER FUND--This fund invests in money market instruments,
intermediate and long-term bonds and equities. The goal of this fund is to seek
high total return with reduced investment risk over the long term.

f. FIDELITY MANAGED INCOME PORTFOLIO II--This portfolio invests in contracts
with rates and maturities that are set monthly and provide current, competitive
interest rates. The portfolio also invests in longer term Guaranteed Investment
Contracts (GICs) with fixed rates of interest. This portfolio seeks preservation
of capital and a competitive level of income over time.

g. SPARTAN U.S. EQUITY INDEX PORTFOLIO--This portfolio invests in common stocks
of the companies that make up the Standard and Poor's (S&P) 500 Index. The goal
of this account is to model the S&P 500 Index in such a way that the account's
performance is similar to that of the Index.

h. FIDELITY MAGELLAN--This fund invests primarily in common stocks. Invests in
domestic and foreign issuers. Invests in either growth or value stocks or both.
The value of the fund's domestic and foreign investments will vary from day to
day in response to many factors.

i. T. ROWE PRICE SCIENCE & TECHNOLOGY FUND--The fund seeks long-term growth of
capital. The fund's strategy is to invest at least 65% of total assets in common
stocks of companies expected by T. Rowe Price to benefit from development,
advancement, and the use of science and technology.

j. BANC ONE BOND FUND--With its portfolio of intermediate and long-term bonds,
the fund strives to maximize total return and provide a high level of monthly
income. In most cases, the fund invests at least 75% of its assets in
high-quality, investment-grade bonds rated AA or better.

k. FIDELITY FREEDOM 2000, 2010, 2020, 2030, 2040 FUND--The objective of these
funds is to seek a high total return. Underlying securities are other Fidelity
mutual funds. Designed for investors who expect to retire around the respective
fund date. The fund does not mature in the respective year; its allocation
strategy becomes increasingly conservative as it approaches its target
retirement year.

l. FIDELITY CONTRAFUND--Seeks capital appreciation. Invests primarily in common
stocks of companies whose value FMR believes is not fully recognized by the
public. The types of companies in which the fund may invest include companies
experiencing positive fundamental change such as a new management team or
product launch.


                                       6


m. WABTEC COMMON STOCK FUND--This is a concentrated investment with results
depending entirely on the performance of the company's common stock. Shares will
be purchased for the account at the current market price.

Investments are valued at their market values based on published quotations or,
in the absence of readily ascertainable market values, at such values as the
trustee will determine.

Tax Status
----------

The Plan has not received a determination letter from the Internal Revenue
Service stating that the Plan is qualified under Section 401(a) of the Internal
Revenue Code (the "Code"). However, the Plan Administrator represents and
believes that the Plan is qualified and, therefore, the related trust is exempt
from taxation

Use of Estimates in the Preparation of Financial Statements
-----------------------------------------------------------

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires the plan administrator to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results may differ from these
estimates.

3. INVESTMENTS:
  -------------

The trustee of the Plan held the Plan's investments and executed transactions
therein. The fair market values of individual assets that represent 5% or more
of the Plan's net assets as of December 31, 2001 and 2000 are as follows:

                                                  2001       2000

      Spartan U.S. Equity Index Portfolio         18,555     34,869

4. PLAN TERMINATION:
   -----------------

In the event the Plan is terminated, the Company will direct either (a) that the
investment manager and trustee continue to hold the participants' accounts in
accordance with the Plan, or (b) that the investment manager and trustee
immediately distribute to each participant all amounts in the participant's
account in a single lump-sum payment.
