REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Westinghouse Air Brake Company Employee Stock Ownership Plan: We have audited the accompanying statement of net assets available for benefits of the Westinghouse Air Brake Company Employee Stock Ownership Plan (the Plan) as of December 31, 1999, and the related statement of changes in net assets available for benefits for the period from January 1, 2000 to July 31, 2000. In addition, we have audited the statement of net assets available for benefits in liquidation as of December 31, 2000, and the related statement of changes in net assets available for benefits in liquidation for the period from August 1, 2000 to December 31, 2000. These financial statements and the schedule referred to below are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits. We conducted our audits in accordance with generally accepted auditing standards 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 audits provide a reasonable basis for our opinion. As described in Note 1 to the financial statements, the Board of Directors of Westinghouse Air Brake Technologies Corporation approved the termination of the Plan effective July 31, 2000. As a result, the Plan has changed its basis of accounting for the periods subsequent to July 31, 2000, from the accrual basis to the liquidation basis. Accordingly, the carrying value of the remaining assets as of December 31, 2000 are presented at estimated realizable values and all liabilities are presented at estimated settlement amounts. 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, 1999, and the changes in its net assets available for benefits for the period from January 1, 2000 to July 31, 2000, its net assets available for benefits of the Plan as of December 31, 2000, and the changes in net assets available for benefits in liquidation for the period from August 1, 2000 to December 31, 2000, in conformity with accounting principles generally accepted in the United States applied on the bases described in the preceding paragraph. Our audits were made for the purpose of forming an opinion on the financial statements taken as a whole. The supplemental Schedule of Assets Held for Investment Purposes is presented for the purpose 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.

WESTINGHOUSE AIR BRAKE COMPANY EMPLOYEE STOCK OWNERSHIP PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2001 AND 2000 1. DESCRIPTION OF THE PLAN: The following description of the Westinghouse Air Brake Company Employee Stock Ownership Plan (the Plan) is provided for general information purposes only. Participants should refer to the Plan document for more complete information. On July 20, 2000, the Board of Directors approved a plan to terminate the ESOP. All existing ESOP participants were fully vested in their allocated ESOP account balances as of the termination date. Beginning August 2000, ESOP contributions were replaced with cash contributions by the Company into the employees' savings plan accounts. Effective July 31, 2000, the Company filed the appropriate documents to terminate the Plan with the Department of the Treasury. As of December 31, 2001 and 2000, the plan assets and liabilities are presented on a liquidation basis presentation to illustrate the effect of plan termination as if it occurred on December 31, 2001 and 2000. The Company plans to purchase the unallocated shares from the ESOP upon final termination of the Plan. The Plan will then settle its debt obligation to the Company based on the market price of the Company's common stock at termination and mutual agreement between the parties. This will result in future adjustments to the liquidation basis presentation at the time of settlement. On February 26, 2002, the Internal Revenue Service issued a determination letter stating that the Amended and Restated Plan, which incorporates the necessary changes to terminate the Plan, meets the requirement of the Internal Revenue Code Sections 401 (a) and 501 (a) at termination. The Plan's debt obligation was extinguished in its entirety in connection with the return of the Plan's unallocated shares to the Company on June 3, 2002. The final settlement value of the obligation was approximately $105,000,000. The Company has filed a termination notice with the Department of Treasury and, accordingly, the Plan's financial statements are prepared on a liquidation basis. General Westinghouse Air Brake Technologies Corporation (formerly Westinghouse Air Brake Company) ("Wabtec" or the "Company") established the Plan effective January 1, 1995, amended and restated effective January 1, 1997, as a leveraged employee stock ownership plan (ESOP). The Plan is designed to comply with Section 4975(e)(7) and the regulations thereunder of the Internal Revenue Code of 1986, as amended (the Code), and is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). Overall responsibility for administering the Plan rests with the Plan Administrative Committee (the Committee) which is appointed by the Board of Directors of the Company. The Plan's Trustee, U.S. Trust Company of California, N.A., is responsible for the management and control of the Plan's assets and has discretionary responsibility for the investment and management of such assets. In 1995, the Plan entered into a $140,040,000 term loan agreement with Wabtec. The proceeds of the loan were used to purchase 9,336,000 shares of Wabtec common stock at $15 per share. Unallocated shares were collateral for the loan. The agreement provided for the loan to be repaid over 50 years, and bore interest at 8.5%. The loan payments were required to be funded by Company contributions to the trust fund. As the Plan made payments of principal, an appropriate percentage of stock was allocated to eligible employees' individual accounts. 12

The unallocated shares of stock collateralize the borrowing. Shares no longer serve as collateral once they are allocated under the ESOP. Accordingly, the financial statements of the Plan present separately the assets and liabilities and changes therein pertaining to the following: - The accounts of employees with vested rights in allocated stock (allocated). - Stock yet to be allocated to employees (unallocated). Vesting Employees become fully vested upon completion of five years of continuous service, attainment of normal retirement or termination of service by reason of death. The unvested portion of a participant's account will be reallocated to the accounts of the remaining participants. Eligibility Employees of Wabtec and its participating subsidiaries, who were eligible to participate in the Westinghouse Air Brake Company Savings Plan as of December 31, 1994, were automatically participants in the Plan on January 1, 1995. All other employees who may become eligible to participate in the Plan would do so after performing one hour of salaried service. Employer Contributions Wabtec is obligated to make contributions to the Plan which, when aggregated with the Plan's dividends and interest earnings, equal the amount necessary to enable the Plan to make its regularly scheduled payments of principal and interest due on its term loan from the Company. Participant Accounts The Plan is a defined contribution plan under which separate individual accounts are established for each participant. Each participant's account is credited as of the last day of each plan year with an allocation of shares of Wabtec common stock released by the trustee from the suspense account and forfeitures of terminated participants' nonvested accounts. Only those participants who are eligible employees of the Company as of the last day of the plan year will receive an allocation. Shares are allocated to participant accounts based on a two-step process. First, the participant accounts are matched up to 3% of the value of the participant's contributions to the Wabtec Savings Plan and awarded shares determined based on the lesser of their fair market value at the time of allocation or the Plan's cost basis of Company stock. The remaining shares released are allocated proportionately based on each participant's salary. Benefits Distributions must commence in accordance with the following rules: Distributions Before January 1, 2000 Except as described below, for a participant who reaches age 70 1/2 during a plan year ending before January 1, 2000, or for a participant who is a five percent owner of the Company, distributions of such participant's benefits must commence no later than April 1 of the calendar year next following the calendar year in which the participant attains age 70 1/2. Distributions After January 1, 2000 For a participant (other than a five percent owner) who reaches age 70 1/2 during a plan year commencing on or after January 1, 2000, distributions of such participant's benefits must commence no later than April 1 of the calendar year next following the later of (i) the calendar year in which the participant attains age 70 1/2 or (ii) the calendar year in which the participant terminates employment for any reason. 13

Optional Distribution Elections Effective as of January 1, 1998, any active participant who is not a five percent owner and who would otherwise be required to commence distributions (or has already commenced distributions) in accordance with the first paragraph described above, may elect, in accordance with procedures established by the Committee, to defer commencement of his distributions (or, if applicable, suspend his ongoing distributions) until his termination of employment in accordance with the paragraph above. If distribution has commenced and the participant dies before his entire account has been distributed to the individual, the remaining portion of his account will be distributed to his beneficiary under the method used prior to the participant's death. Participant benefits will generally be paid in cash or stock at their election. In connection with a cash distribution, the participant's shares are converted based upon the fair market value of the Wabtec stock with the resulting cash balance paid to the participant. 2. SIGNIFICANT ACCOUNTING POLICIES: Liquidation Basis of Accounting The accompanying financial statements have been prepared on the liquidation basis. Based on a mutual agreement between the parties, the Plan has agreed to settle its debt obligation to the Company for consideration of the Plan's return of the Company's unallocated common stock (see Note 1). 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 management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. During 2000, the Plan estimated the number of shares that were to be allocated to participant accounts based on certain actions anticipated to be taken in connection with the termination of the Plan. During 2001, the actions were finalized and actual number of shares to be allocated was determined. Accordingly, the accompanying statement of changes in net assets reflects a change in estimate to the number of shares allocated (8,327 shares) in the amount of $97,842. Investments As of December 31, 2001 and 2000, investments in Wabtec common stock are stated at market value. Operating Expenses Wabtec pays all expenses of maintaining the Plan. Net Appreciation (Depreciation) in Fair Value of Investments Net realized and unrealized appreciation (depreciation) is recorded in the accompanying financial statements as net appreciation (depreciation) in fair value of investments. 3. INVESTMENTS: The Plan is invested in shares of Wabtec common stock. These shares are held in a bank-administered trust fund. 14

4. DUE TO EMPLOYER: Subsequent to the Plan's termination, dividends were paid on the unallocated shares. Upon termination, dividend payments are no longer required for the unallocated shares. Accordingly, the Plan has recorded a payable to the Company in the amount of $283,964 representing the excess dividend payments received by the Plan. 5. Tax Status: The Plan has received a determination letter from the Internal Revenue Service dated February 26, 2002, stating that the termination of the Plan (effective July 31, 2000) did not adversely affect the Plan's qualified tax status under Section 401(a) of the Internal Revenue Code (the "Code") and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan is qualified and the related trust is tax exempt. 6. RECONCILIATION TO FORM 5500: As of December 31, 2001, the Plan had $81,694 of pending distributions to participants who elected to withdraw from the operation and earnings of the Plan. These amounts are recorded as a liability in the Plan's Form 5500; however, these amounts are not recorded as a liability in the accompanying statements of net assets available for benefits in accordance with generally accepted accounting principles. The following table reconciles net assets available for benefits per the financial statements to the Form 5500 as filed by the Company for the year ended December 31, 2001: Benefits Net Assets Benefits Payable to Available for Benefits Payments Participants December 31, 2001 ------------ ------------ ---------------------- Per financial statements $ 871,754 $ -- $ 11,220,281 Prior year accrued benefit payments (185,727) -- 185,727 Current year accrued benefit payments 81,694 81,694 (81,694) ------------ ------------ ------------ Per Form 5500 $ 767,721 $ 81,694 $ 11,324,314 ============ ============ ============ 15

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Westinghouse Air Brake Technologies Corporation Savings Plan and Participants: We have audited the accompanying statement of net assets available for benefits of the Westinghouse Air Brake Technologies Corporation Savings Plan 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 audits. 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 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. The Company makes an annual contribution of 3% of a participant's eligible compensation, as long as the participant is employed by the Company at December 31. In addition, the Company makes a matching contribution of up to 3% of the participant's contributions. 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.

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. Principles of Presentation The net assets of the Plan are held in a Master Trust (Trust). The Trust consists of the following plans at December 31, 2001: o Westinghouse Air Brake Technologies Corporation Savings Plan o Westinghouse Air Brake Technologies Corporation Supplemental Plan The Statements of Net Assets Available for Benefits present the assets held in trust for the benefit of the Plan's participants. Each of the plans shares pro rata in the commonly held investment of the Trust. Investment income and realized and unrealized appreciation (depreciation) in the fair value of investments are allocated to the Plan based upon the relationship of net assets of the Plan at the beginning of the reportable period to total net assets of the Trusts. Cash and accrued income are allocated to the Plan based on the relationship of the Plan's investments to total investments. The Plan's net assets represent 98% of the net assets of the Master Trust. At December 31, 2001 investments in the Master Trust are as follows: Year Ended December 31, 2001 Net Appreciation (Depreciation) in Market Value at Market Value During Year End of Year ---------------------------- ---------------------------------- --------------- Market value as determined by quoted market price - Corporate common stock 217,504 3,318,104 Equity mutual funds (13,332,755) 67,991,183 Fixed income mutual funds - 25,073,704 Bond funds 139,849 2,174,015 Participant loans - 2,516,764 Investment Options The trustee of the investments is Fidelity Management Trust Company (Fidelity) per the Trust Agreement dated June 21, 1990.

The Plan Sponsor has indicated that it will take the necessary steps, if any, to maintain the Plan's qualified status.

Actual results may differ from these estimates. 3. INVESTMENTS: The trustee of the Plan held the Plan's investments and executed transactions therein.

NOTICE REGARDING CONSENT OF ARTHUR ANDERSEN LLP On May 30, 2002, the Westinghouse Air Brake Technologies Corporation Savings Plan dismissed Arthur Andersen LLP as its independent auditors. Prior to the date of this Form 11-K, the Arthur Andersen partner responsible for the audit of the financial statements of the Westinghouse Air Brake Technologies Corporation Savings Plan as of December 31, 2000 and for the year then ended resigned from Arthur Andersen. As a result, after reasonable efforts, the Plan has been unable to obtain Arthur Andersen's written consent to the incorporation by reference into the Westinghouse Air Brake Technologies Corporation's registration statements on Form S-8 No. 333-33998 of Arthur Andersen's audit report with respect to the Plan's financial statements as of December 31, 2000 and for the year then ended. Under these circumstances, Rule 437a under the Securities Act permits the Plan to file this Form 11-K, which is incorporated by reference into Westinghouse Air Brake Technologies Corporation's filings on Form S-8 No. 333-33998 and deemed to be a new registration statement, without a written consent from Arthur Andersen. However, as a result, Arthur Andersen will not have any liability under Section 11(a) of the Securities Act for any untrue statements of a material fact contained in the financial statements audited by Andersen LLP or any omissions of a material fact required to be stated therein. Accordingly, you would be unable to assert a claim against Arthur Andersen under Section 11(a) of the Securities Act. 35
