Business Combinations [Abstract]
PROPOSED TRANSACTION WITH FAIVELEY TRANSPORT S.A.	PROPOSED TRANSACTION WITH FAIVELEY TRANSPORT S.A. On July 27, 2015, the Company announced plans to acquire Faiveley Transport S.A. ("Faiveley Transport"), a leading global provider of value-added, integrated systems and services for the railway industry with annual sales of about $1.2 billion and more than 5,700 employees in 24 countries. Faiveley Transport supplies railway manufacturers, operators and maintenance providers with a range of valued-added, technology-based systems and services in Energy & Comfort (air conditioning, power collectors and converters, and passenger information), Access & Mobility (passenger access systems and platform doors), and Brakes & Safety (braking systems and couplers). The transaction has been structured in three steps: • Wabtec made an irrevocable offer to the owners of approximately 51% of Faiveley Transport’s shares for a purchase price of €100 per share, payable 25% in cash and 75% in Wabtec preferred stock. The preferred stock will have a 1% annual dividend or, if greater, the annual dividend assuming full conversion into common shares, and must be converted after three years into Wabtec common shares at an implied ratio of one Faiveley Transport common share for 1.125 Wabtec common shares. Shareholders owning 51% of Faiveley Transport have entered into exclusive discussions with Wabtec. • Upon completion of required labor group consultations, on October 6, 2015, the 51% shareholders entered into a definitive share purchase agreement and Faiveley Transport entered into an acquisition agreement with Wabtec. • Upon completing the share purchase, Wabtec will commence a tender offer for the remaining publicly traded Faiveley Transport shares. The public shareholders will have the option to elect to receive €100 per share in cash or Wabtec preferred stock. The preferred stock portion of the consideration is subject to a cap of 75% of Faiveley Transport’s common shares. Wabtec intends to delist Faiveley Transport from Euronext after the tender offer if minority interests represent less than 5% . The total purchase price offered is about $1.8 billion , including assumed debt. Wabtec plans to fund the cash portion of the transaction with cash on hand, existing credit facilities and potentially other credit and debt financing. Prior to December 31, 2015 , Wabtec set aside €186.9 million as an escrow deposit for the Faiveley Transport purchase. The combination of Wabtec and Faiveley Transport would create one of the world’s largest public rail equipment companies, with revenues of about $4.5 billion and a presence in all key freight rail and passenger transit geographies worldwide. Closing of the transaction is subject to various conditions, including completion of regulatory requirements. These steps are currently on-going and the timing of completion is unknown.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. Such statements have been prepared in accordance with U.S. generally accepted accounting principles. Sales between subsidiaries are billed at prices consistent with sales to third parties and are eliminated in consolidation. Capital Structure On May 14, 2013, our stockholders approved an amendment to our Amended and Restated Certificate of Incorporation to increase the number of authorized shares of our common stock to 200.0 million shares. In addition, on May 14, 2013, our Board of Directors approved a two -for-one split of the Company’s issued and outstanding common stock in the form of a 100% stock dividend. The increase in the authorized shares and the stock split became effective on May 14, 2013 and June 11, 2013, respectively. The Company issued approximately 66.2 million shares of its common stock as a result of the two -for-one stock split. The par value of the Company’s common stock remained unchanged at $0.01 per share. Information regarding shares of common stock (except par value per share), retained earnings, and net income per common share attributable to Wabtec shareholders for all periods presented reflects the two -for-one split of the Company’s common stock. The number of shares of the Company’s common stock issuable upon exercise of outstanding stock options and vesting of other stock-based awards was proportionally increased, and the exercise price per share thereof was proportionally decreased, in accordance with the terms of the stock incentive plans. Cash Equivalents Cash equivalents are highly liquid investments purchased with an original maturity of three months or less. Allowance for Doubtful Accounts The allowance for doubtful accounts receivable reflects our best estimate of probable losses inherent in our receivable portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. The allowance for doubtful accounts was $5.6 million and $6.3 million as of December 31, 2015 and 2014 , respectively. Inventories Inventories are stated at the lower of cost or market. Cost is determined under the first-in, first-out (FIFO) method. Inventory costs include material, labor and overhead. Property, Plant and Equipment Property, plant and equipment additions are stated at cost. Expenditures for renewals and improvements are capitalized. Expenditures for ordinary maintenance and repairs are expensed as incurred. The Company provides for book depreciation principally on the straight-line method. Accelerated depreciation methods are utilized for income tax purposes. Leasing Arrangements The Company conducts a portion of its operations from leased facilities and finances certain equipment purchases through lease agreements. In those cases in which the lease term approximates the useful life of the leased asset or the lease meets certain other prerequisites, the leasing arrangement is classified as a capital lease. The remaining arrangements are treated as operating leases. Intangible Assets Goodwill and other intangible assets with indefinite lives are not amortized. Other intangibles (with definite lives) are amortized on a straight-line basis over their estimated economic lives. Amortizable intangible assets are reviewed for impairment when indicators of impairment are present. The Company tests goodwill and indefinite-lived intangible assets for impairment at least annually. The Company performs its annual impairment test during the fourth quarter after the annual forecasting process is completed, and also tests for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Periodically, Management of the Company assesses whether or not an indicator of impairment is present that would necessitate an impairment analysis be performed. For 2015, the Company opted to perform a qualitative goodwill assessment and determined that step two was not necessary. In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we assess relevant events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of relevant events and circumstances and how these may impact a reporting unit’s fair value or carrying amount involve significant judgments and assumptions. The judgment and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Wabtec specific events and share price trends and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact. If our qualitative assessment concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company then performs a two-step impairment test. In the first step of the quantitative assessment, our assets and liabilities, including existing goodwill and other intangible assets, are assigned to the identified reporting units to determine the carrying value of the reporting units. The Company reviews goodwill for impairment at the reporting unit level. The Company prepares its goodwill impairment analysis by comparing the estimated fair value of each reporting unit, using an income approach (a discounted cash flow model) as well as a market approach, with its carrying value. The income approach and the market approach are equally weighted in arriving at fair value, which the Company has applied consistently. The discounted cash flow model requires several assumptions including future sales growth, EBIT (earnings before interest and taxes) margins and capital expenditures for the reporting units. The discounted cash flow model also requires the use of a discount rate and a terminal revenue growth rate (the revenue growth rate for the period beyond the three years forecasted by the reporting units), as well as projections of future operating margins. The market approach requires several assumptions including EBITDA (earnings before interest, taxes, depreciation and amortization) multiples for comparable companies that operate in the same markets as the Company’s reporting units. Warranty Costs Warranty costs are accrued based on Management’s estimates of repair or upgrade costs per unit and historical experience. Warranty expense was $35.4 million , $34.1 million and $22.9 million for 2015 , 2014 and 2013 , respectively. Accrued warranty was $92.1 million and $87.8 million at December 31, 2015 and 2014 , respectively. Income Taxes Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws. The provision for income taxes includes federal, state and foreign income taxes. Stock-Based Compensation The Company recognizes compensation expense for stock-based compensation based on the grant date fair value amortized ratably over the requisite service period following the date of grant. Financial Derivatives and Hedging Activities The Company has entered into foreign currency forward contracts to reduce the impact of changes in currency exchange rates. Foreign currency forward contracts are agreements with a counterparty to exchange two distinct currencies at a set exchange rate for delivery on a set date at some point in the future. There is no exchange of funds until the delivery date. At the delivery date the Company can either take delivery of the currency or settle on a net basis. At December 31, 2015 , the Company had no material foreign currency forward contracts. To reduce the impact of interest rate changes on a portion of it's variable-rate debt, the Company has entered into two forward starting interest rate swap agreement with a notional value of $150 million . As of December 31, 2015 , the Company has recorded a current liability of $4.5 million and a corresponding offset in accumulated other comprehensive loss of $2.7 million , net of tax, related to these agreements. For further information regarding the forward starting interest rate swap agreements, see Footnote 9. Foreign Currency Translation Assets and liabilities of foreign subsidiaries, except for the Company’s Mexican operations whose functional currency is the U.S. Dollar, are translated at the rate of exchange in effect on the balance sheet date while income and expenses are translated at the average rates of exchange prevailing during the period. Foreign currency gains and losses resulting from transactions, and the translation of financial statements are recorded in the Company’s consolidated financial statements based upon the provisions of Accounting Standards Codification (“ASC”) 830, “Foreign Currency Matters.” The effects of currency exchange rate changes on intercompany transactions and balances of a long-term investment nature are accumulated and carried as a component of accumulated other comprehensive loss. The effects of currency exchange rate changes on intercompany transactions that are denominated in a currency other than an entity’s functional currency are charged or credited to earnings. Foreign exchange transaction losses recognized in other (expense) income, net were $4.7 million , $2.4 million and $3.5 million for 2015 , 2014 and 2013 , respectively. Noncontrolling Interests In accordance with ASC 810, the Company has classified noncontrolling interests as equity on our condensed consolidated balance sheets as of December 31, 2015 and 2014 . Net income attributable to noncontrolling interests for the years ended December 31, 2015 , 2014 and 2013 was not material. Other Comprehensive Income (Loss) Comprehensive income (loss) is defined as net income and all other non-owner changes in shareholders’ equity. The Company’s accumulated other comprehensive income consists of foreign currency translation adjustments, foreign currency hedges, foreign exchange contracts, interest rate swaps, and pension and post retirement related adjustments. Revenue Recognition Revenue is recognized in accordance with ASC 605 “Revenue Recognition,” The Company recognized revenue when the following criteria are met: 1) persuasive evidence of an arrangement exists; 2) delivery has occurred; 3) an established sales price has been set with the customer; 4) collection of the sale revenue from the customer is reasonably assured; and 5) no contingencies exist. Delivery is considered to have occurred when the customer assumes the risk and rewards of ownership. The Company estimates and records provisions for quantity rebates and sales returns and allowances as an offset to revenue in the same period the related revenue is recognized, based upon its experience. These items are included as a reduction in deriving net sales. In general, the Company recognizes revenues on long-term contracts based on the percentage of completion method of accounting. The units-of-delivery method or other input-based or output-based measures, as appropriate, are used to measure the progress toward completion of individual contracts. Contract revenues and cost estimates are reviewed and revised quarterly at a minimum and adjustments are reflected in the accounting period as such amounts are determined. Provisions are made currently for estimated losses on uncompleted contracts. Unbilled accounts receivables were $103.8 million and $187.8 million , customer deposits were $106.1 million and $111.8 million , and provisions for loss contracts were $11.8 million and $7.1 million at December 31, 2015 and 2014 , respectively. Certain pre-production costs relating to long-term production and supply contracts have been deferred and will be recognized over the life of the contracts. Deferred pre-production costs were $30.3 million and $24.9 million at December 31, 2015 and 2014 , respectively. Significant Customers and Concentrations of Credit Risk The Company’s trade receivables are from rail and transit industry original equipment manufacturers, Class I railroads, railroad carriers and commercial companies that utilize rail cars in their operations, such as utility and chemical companies. No one customer accounted for more than 10% of the Company’s consolidated net sales in 2015 , 2014 or 2013 . Shipping and Handling Fees and Costs All fees billed to the customer for shipping and handling are classified as a component of net revenues. All costs associated with shipping and handling is classified as a component of cost of sales. Research and Development Research and development costs are charged to expense as incurred. For the years ended December 31, 2015 , 2014 and 2013 , the Company incurred costs of approximately $71.2 million , $61.9 million , and $46.3 million , respectively. Employees As of December 31, 2015 , approximately 30% of the Company’s workforce was covered by collective bargaining agreements. These agreements are generally effective from 2015 through 2017. Agreements expiring in 2015 cover approximately 26% of the Company’s workforce. Earnings Per Share Basic and diluted earnings per common share is computed in accordance with ASC 260 “Earnings Per Share.” Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and included in the computation of earnings per share pursuant to the two-class method included in ASC 260-10-55. (See Note 12 “Earnings Per Share” included herein) Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from the estimates. On an ongoing basis, Management reviews its estimates based on currently available information. Changes in facts and circumstances may result in revised estimates. Recent Accounting Pronouncements In April 2015, the FASB issued Accounting Standards Update No. 2015-3, “Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-3”) which changes the presentation of debt issuance costs in financial statements to present such costs as a direct deduction from the related debt liability rather than as an asset. ASU 2015-3 will become effective for public companies during interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this standard is not expected to have a material impact to the financial statements. The Company will make the required changes in the first quarter of 2016. In May 2014, the FASB issued ASU no. 2014-9, “Revenue from Contract with Customers.” The ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Board voted to propose that the standard would take effect for reporting periods beginning after December 15, 2017 and that early adoption would be allowed as of the original effective date. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU No. 2015-17, “Balance Sheet Classification of Deferred Taxes” as part of their simplification initiatives. The update requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The update is effective for financial periods beginning after December 15, 2017; however, early application is permitted. The adoption of this standard is not expected to have a material impact to the financial statements.

Business Combinations [Abstract]
ACQUISITIONS	PROPOSED TRANSACTION WITH FAIVELEY TRANSPORT S.A. On July 27, 2015, the Company announced plans to acquire Faiveley Transport S.A. ("Faiveley Transport"), a leading global provider of value-added, integrated systems and services for the railway industry with annual sales of about $1.2 billion and more than 5,700 employees in 24 countries. Faiveley Transport supplies railway manufacturers, operators and maintenance providers with a range of valued-added, technology-based systems and services in Energy & Comfort (air conditioning, power collectors and converters, and passenger information), Access & Mobility (passenger access systems and platform doors), and Brakes & Safety (braking systems and couplers). The transaction has been structured in three steps: • Wabtec made an irrevocable offer to the owners of approximately 51% of Faiveley Transport’s shares for a purchase price of €100 per share, payable 25% in cash and 75% in Wabtec preferred stock. The preferred stock will have a 1% annual dividend or, if greater, the annual dividend assuming full conversion into common shares, and must be converted after three years into Wabtec common shares at an implied ratio of one Faiveley Transport common share for 1.125 Wabtec common shares. Shareholders owning 51% of Faiveley Transport have entered into exclusive discussions with Wabtec. • Upon completion of required labor group consultations, on October 6, 2015, the 51% shareholders entered into a definitive share purchase agreement and Faiveley Transport entered into an acquisition agreement with Wabtec. • Upon completing the share purchase, Wabtec will commence a tender offer for the remaining publicly traded Faiveley Transport shares. The public shareholders will have the option to elect to receive €100 per share in cash or Wabtec preferred stock. The preferred stock portion of the consideration is subject to a cap of 75% of Faiveley Transport’s common shares. Wabtec intends to delist Faiveley Transport from Euronext after the tender offer if minority interests represent less than 5% . The total purchase price offered is about $1.8 billion , including assumed debt. Wabtec plans to fund the cash portion of the transaction with cash on hand, existing credit facilities and potentially other credit and debt financing. Prior to December 31, 2015 , Wabtec set aside €186.9 million as an escrow deposit for the Faiveley Transport purchase. The combination of Wabtec and Faiveley Transport would create one of the world’s largest public rail equipment companies, with revenues of about $4.5 billion and a presence in all key freight rail and passenger transit geographies worldwide. Closing of the transaction is subject to various conditions, including completion of regulatory requirements. These steps are currently on-going and the timing of completion is unknown.

The Company incurred approximately $1.0 million of deferred financing cost related to the 2013 Refinancing Credit Agreement. The facility expires on December 19, 2018 . The 2013 Refinancing Credit Agreement borrowings bear variable interest rates indexed as described below. At December 31, 2015 , the Company had available bank borrowing capacity, net of $21.9 million of letters of credit, of approximately $333.1 million , subject to certain financial covenant restrictions. Under the 2013 Refinancing Credit Agreement, the Company may elect a Base Rate of interest for U.S. Dollar denominated loans or, for certain currencies, an interest rate based on the London Interbank Offered Rate (“LIBOR”) of interest, or other rates appropriate for such currencies (in any case, “the Alternate Rate”). The Base Rate adjusts on a daily basis and is the greater of the Federal Funds Effective Rate plus 0.5% per annum, the PNC, N.A. prime rate or the Daily LIBOR Rate plus 100 basis points , plus a margin that ranges from 0 basis points to 75 basis points . The Alternate Rate is based on the quoted rates specific to the applicable currency, plus a margin that ranges from 75 basis points to 175 basis points . Both the Base Rate and Alternate Rate margins are dependent on the Company’s consolidated total indebtedness to cash flow ratios. The initial Base Rate margin is 0 basis points and the Alternate Rate margin is 75 basis points . At December 31, 2015 the weighted average interest rate on the Company’s variable rate debt was 1.10% . On January 12, 2012 , the Company entered into a forward starting interest rate swap agreement with a notional value of $150.0 million . The effective date of the interest rate swap agreement is July 31, 2013 , and the termination date is November 7, 2016 . The impact of the interest rate swap agreement converts a portion of the Company’s outstanding debt from a variable rate to a fixed-rate borrowing. During the term of the interest rate swap agreement the interest rate on the notional value will be fixed at 1.415% plus the Alternate Rate margin. On June 5, 2014 , the Company entered into a forward starting interest rate swap agreement with a notional value of $150.0 million . The effective date of the interest rate swap agreement is November 7, 2016 , and the termination date is December 19, 2018 . The impact of the interest rate swap agreement converts a portion of the Company’s outstanding debt from a variable rate to a fixed-rate borrowing. During the term of the interest rate swap agreement the interest rate on the notional value will be fixed at 2.56% plus the Alternate Rate margin. As for these agreements, the Company is exposed to credit risk in the event of nonperformance by the counterparties. However, since only the cash interest payments are exchanged, exposure is significantly less than the notional amount. The counterparties are large financial institutions with an excellent credit rating and history of performance. The Company currently believes the risk of nonperformance is negligible. The 2013 Refinancing Credit Agreement limits the Company’s ability to declare or pay cash dividends and prohibits the Company from declaring or making other distributions, subject to certain exceptions. The 2013 Refinancing Credit Agreement contains various other covenants and restrictions including the following limitations: incurrence of additional indebtedness; mergers, consolidations, sales of assets and acquisitions; additional liens; sale and leasebacks; permissible investments, loans and advances; certain debt payments; and imposes a minimum interest expense coverage ratio of 3.0 and a maximum debt to cash flow ratio of 3.25 . The Company does not expect that these measurements will limit the Company in executing our operating activities. 2011 Refinancing Credit Agreement On November 7, 2011 , the Company refinanced its existing revolving credit and term loan facility with a consortium of commercial banks. This “2011 Refinancing Credit Agreement” provided the company with a $600.0 million , five -year revolving credit facility. The Company incurred approximately $1.9 million of deferred financing cost related to the 2011 Refinancing Credit Agreement. The facility was set to expire on November 7, 2016 . Under the 2011 Refinancing Credit Agreement, the Company may have elected a Base Rate of interest or an interest rate based on the London Interbank Offered Rate (“LIBOR”) of interest (“the Alternate Rate”). The Base Rate adjusted on a daily basis and was the greater of the Federal Funds Effective Rate plus 0.5% per annum, the PNC, N.A. prime rate or the Daily LIBOR Rate plus 100 basis points plus a margin that ranged from 0 basis points to 75 basis points . The Alternate Rate was based on quoted LIBOR rates plus a margin that ranged from 75 basis points to 175 basis points . Both the Base Rate and Alternate Rate margins were dependent on the Company’s consolidated total indebtedness to cash flow ratios. The current Base Rate margin was 0 basis points and the Alternate Rate margin was 100 basis points . 4.375% Senior Notes Due August 2023 In August 31, 2013 , the Company issued $250.0 million of Senior Notes due in 2023 (“the 2013 Notes”). Interest on the 2013 Notes accrues at a rate of 4.375% per annum and is payable semi-annually on February 15 and August 15 of each year. The proceeds were used to repay debt outstanding under the Company’s existing credit agreement, and for general corporate purposes. The principal balance is due in full at maturity. The Company incurred $2.6 million of deferred financing costs related to the issuance. The 2013 Notes are senior unsecured obligations of the Company and rank pari passu with all existing and future senior debt and senior to all existing and future subordinated indebtedness of the Company. The indenture under which the 2013 Notes were issued contains covenants and restrictions which limit among other things, the following: the incurrence of indebtedness, payment of dividends and certain distributions, sale of assets, change in control, mergers and consolidations and the incurrence of liens. The Company is in compliance with the restrictions and covenants in the indenture under which the 2013 Notes were issued and expects that these restrictions and covenants will not be any type of limiting factor in executing our operating activities. 6.875% Senior Notes Due August 2013 In August 31, 2003 , the Company issued $150.0 million of Senior Notes due in 2013 (“the 2003 Notes”). The 2003 Notes were issued at par. Interest on the 2003 Notes accrued at a rate of 6.875% per annum and was payable semi-annually on January 31 and July 31 of each year. The proceeds were used to repay debt outstanding under the Company’s existing credit agreement and for general corporate purposes. The Company paid off the 2003 Notes, which matured on July 31, 2013 utilizing available capacity under the 2011 Refinancing Credit Agreement. Debt and Capital Leases Scheduled principal repayments of debt and capital lease balances as of December 31, 2015 are as follows: 2016 $ 464 2017 128 2018 445,068 2019 29 2020 11 Future years 250,027 Total $ 695,727

The expected return on plan assets is based on historical performance as well as expected future rates of return on plan assets considering the current investment portfolio mix and the long-term investment strategy. As of December 31, 2015 the following table represents the amounts included in other comprehensive loss that are expected to be recognized as components of periodic benefit costs in 2016 . In thousands U.S. International Net transition obligation $ — $ 150 Prior service cost 3 26 Net actuarial loss 914 2,287 $ 917 $ 2,463 Pension Plan Assets The Company has established formal investment policies for the assets associated with our pension plans. Objectives include maximizing long-term return at acceptable risk levels and diversifying among asset classes. Asset allocation targets are based on periodic asset liability study results which help determine the appropriate investment strategies. The investment policies permit variances from the targets within certain parameters. The plan assets consist primarily of equity security funds, debt security funds, and temporary cash and cash equivalent investments. The assets held in these funds are generally actively managed and are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. Generally, all plan assets are considered Level 2 based on the fair value valuation hierarchy (See Note 18 “Fair Value Measurement” included herein). Plan assets by asset category at December 31, 2015 and 2014 are as follows: U.S. International In thousands 2015 2014 2015 2014 Pension Plan Assets Equity security funds $ 20,275 $ 20,696 $ 87,321 $ 99,715 Debt security funds and other 16,441 20,034 77,173 78,510 Cash and cash equivalents 924 773 3,575 4,029 Fair value of plan assets $ 37,640 $ 41,503 $ 168,069 $ 182,254 The U.S., Canadian and German pension plans have a target asset allocation of 50% equity securities and 50% debt securities. The United Kingdom plan has a target asset allocation of 62.5% equity securities and 37.5% debt securities. Investment policies are determined by the respective Plan’s Pension Committee and set forth in its Investment Policy. Rebalancing of the asset allocation occurs on a quarterly basis. Cash Flows The Company’s funding methods are based on governmental requirements and differ from those methods used to recognize pension expense. The Company expects to contribute $6.2 million to the international plans and does not expect to make a contribution to the U.S. plans during 2016 . Benefit payments expected to be paid to plan participants are as follows: In thousands U.S. International Year ended December 31, 2016 $ 3,399 $ 6,939 2017 3,519 7,261 2018 3,388 7,487 2019 3,394 7,733 2020 3,372 7,854 2021 through 2025 15,820 42,040 Post Retirement Benefit Plans In addition to providing pension benefits, the Company has provided certain unfunded postretirement health care and life insurance benefits for a portion of North American employees. The Company is not obligated to pay health care and life insurance benefits to individuals who had retired prior to 1990.

In thousands U.S. International Prior service cost (2,294 ) (7 ) Net actuarial loss (gain) 1,355 (30 ) $ (939 ) $ (37 ) The assumed health care cost trend rate for the U.S. plans grades from an initial rate of 6.60% to an ultimate rate of 4.50% by 2027 and for international plans from 6.62% to 4.50% by 2027 . A 1.0% increase in the assumed health care cost trend rate will increase the service and interest cost components of the expense recognized for the U.S. and international post-retirement plans by approximately $189,000 and $14,000 , respectively, for 2015, and increase the accumulated post-retirement benefit obligation by approximately $46,000 and $228,000 , respectively. A 1.0% decrease in the assumed health care cost trend rate will decrease the service and interest cost components of the expense recognized for the U.S. and international post-retirement plans by approximately $158,000 and $13,000 , respectively, for 2015, and decrease the accumulated post-retirement benefit obligation by approximately $42,000 and $206,000 , respectively.

Costs recognized under these plans are summarized as follows: For the year ended In thousands 2015 2014 2013 Multi-employer pension and health & welfare plans $ 2,584 $ 2,405 $ 2,678 401(k) savings and other defined contribution plans 21,399 19,925 17,291 Total $ 23,983 $ 22,330 $ 19,969 The 401(k) savings plan is a participant directed defined contribution plan that holds shares of the Company’s stock as one of the investment options. At December 31, 2015 and 2014 , the plan held on behalf of its participants about 632,523 shares with a market value of $45.0 million , and 670,322 shares with a market value of $58.2 million , respectively. Additionally, the Company has stock option based benefit and other plans further described in Note 13. The Company contributes to several multi-employer defined benefit pension plans under collective bargaining agreements that cover certain of its union-represented employees. The risks of participating in such plans are different from the risks of single-employer plans. Assets contributed to a multi-employer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer ceases to contribute to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. If the Company ceases to have an obligation to contribute to the multi-employer plan in which it had been a contributing employer, it may be required to pay to the plan an amount based on the underfunded status of the plan and on the history of the Company’s participation in the plan prior to the cessation of its obligation to contribute. The amount that an employer that has ceased to have an obligation to contribute to a multi-employer plan is required to pay to the plan is referred to as a withdrawal liability. The Company’s participation in multi-employer plans for the year ended December 31, 2015 is outlined in the table below. For plans that are not individually significant to the Company, the total amount of contributions is presented in the aggregate.

(3) Critical status triggered a 5% surcharge on employer contributions effective June 2012. Effective January 1, 2013, this surcharge increases to 10% . The surcharge ended on October 21, 2015 when the rehabilitation plan commenced. (a) The “EIN / PN” column provides the Employer Identification Number and the three-digit plan number assigned to a plan by the Internal Revenue Service. (b) The most recent Pension Protection Act Zone Status available for 2013 and 2012 is for plan years that ended in 2013 and 2012, respectively. The zone status is based on information provided to the Company and other participating employers by each plan and is certified by the plan’s actuary. A plan in the “red” zone has been determined to be in “critical status”, based on criteria established under the Internal Revenue Code (“Code”), and is generally less than 65% funded. A plan in the “yellow” zone has been determined to be in “endangered status”, based on criteria established under the Code, and is generally less than 80% funded. A plan in the “green” zone has been determined to be neither in “critical status” nor in “endangered status”, and is generally at least 80% funded. (c) The “FIP/RP Status Pending/Implemented” column indicates whether a Funding Improvement Plan, as required under the Code to be adopted by plans in the “yellow” zone, or a Rehabilitation Plan, as required under the Code to be adopted by plans in the “red” zone, is pending or has been implemented as of the end of the plan year that ended in 2015 . (d) The “Surcharge Imposed” column indicates whether the Company’s contribution rate for 2015 included an amount in addition the contribution rate specified in the applicable collective bargaining agreement, as imposed by a plan in “critical status”, in accordance with the requirements of the Code.

The components of the income from operations before provision for income taxes for the Company’s domestic and foreign operations for the years ended December 31 are provided below: For the year ended In thousands 2015 2014 2013 Domestic $ 461,394 $ 343,180 $ 285,395 Foreign 123,974 164,675 135,692 Income from operations before income taxes $ 585,368 $ 507,855 $ 421,087 Undistributed earnings of the Company’s foreign subsidiaries amounted to approximately $1,004.0 million at December 31, 2015 . Those earnings are considered to be indefinitely reinvested; accordingly, no provision for U.S. federal and state income taxes has been provided thereon. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various foreign countries. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable due to the complexities associated with its hypothetical calculation. The consolidated provision for income taxes included in the Statement of Income consisted of the following: For the year ended December 31, In thousands 2015 2014 2013 Current taxes Federal $ 141,245 $ 108,782 $ 70,459 State 16,072 17,091 13,173 Foreign 24,442 37,356 29,972 181,759 163,229 113,604 Deferred taxes Federal 9,606 2,287 11,146 State 770 1,404 1,375 Foreign (5,395 ) (10,745 ) 2,727 4,981 (7,054 ) 15,248 Total provision $ 186,740 $ 156,175 $ 128,852 A reconciliation of the United States federal statutory income tax rate to the effective income tax rate on operations for the years ended December 31 is provided below: For the year ended December 31, In thousands 2015 2014 2013 U.S. federal statutory rate 35.0 % 35.0 % 35.0 % State taxes 2.0 % 2.2 % 2.2 % Tax reserves (0.4 )% 0.3 % — % Foreign (2.1 )% (4.2 )% (3.9 )% Research and development credit (0.4 )% (0.5 )% (0.6 )% Manufacturing deduction (2.3 )% (1.8 )% (1.7 )% Other, net 0.1 % (0.2 )% (0.4 )% Effective rate 31.9 % 30.8 % 30.6 % Deferred income taxes result from temporary differences in the recognition of income and expense for financial and income tax reporting purposes. These deferred income taxes will be recognized as future tax benefits or costs when the temporary differences reverse. Components of deferred tax assets and liabilities were as follows: December 31, In thousands 2015 2014 Deferred income tax assets: Accrued expenses and reserves $ 39,426 $ 34,167 Warranty reserve 24,544 21,123 Deferred compensation/employee benefits 24,950 21,759 Pension and postretirement obligations 15,507 26,736 Inventory 18,664 13,570 Net operating loss carry forwards 25,636 5,036 Tax credit carry forwards 959 1,078 Gross deferred income tax assets 149,686 123,469 Valuation allowance 12,623 1,818 Total deferred income tax assets 137,063 121,651 Deferred income tax liabilities: Property, plant & equipment 34,518 29,998 Intangibles 167,108 157,781 Other 2,243 144 Total deferred income tax liabilities 203,869 187,923 Net deferred income tax liability $ (66,806 ) $ (66,272 ) A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2015 , the valuation allowance for certain foreign carryforwards was $12.6 million primarily in Brazil and South Africa. State tax credit carry-forwards of approximately $1.0 million expire in various periods from December 31, 2016 to December 31, 2030 . Net operating loss carry-forwards in the amount of $25.6 million expire in various periods from December 31, 2016 to December 31, 2035 . As of December 31, 2015 , the liability for income taxes associated with unrecognized tax benefits was $10.6 million , of which $4.3 million , if recognized, would favorably affect the Company’s effective income tax rate. As of December 31, 2014 , the liability for income taxes associated with unrecognized tax benefits was $12.6 million , of which $5.5 million , if recognized, would favorably affect the Company’s effective tax rate. A reconciliation of the beginning and ending amount of the liability for income taxes associated with unrecognized tax benefits follows: In thousands 2015 2014 2013 Gross liability for unrecognized tax benefits at beginning of year $ 12,596 $ 10,531 $ 11,267 Gross increases - unrecognized tax benefits in prior periods — 30 55 Gross increases - current period unrecognized tax benefits 1,682 2,756 3,279 Gross decreases - unrecognized tax benefits in prior periods — (463 ) — Gross decreases - audit settlement during year (3,027 ) (77 ) (2,515 ) Gross decreases - expiration of audit statute of limitations (694 ) (181 ) (1,555 ) Gross liability for unrecognized tax benefits at end of year $ 10,557 $ 12,596 $ 10,531 The Company includes interest and penalties related to unrecognized tax benefits in income tax expense. As of December 31, 2015 , the total interest and penalties accrued was approximately $2.0 million and $0.2 million , respectively. As of December 31, 2014 , the total interest and penalties accrued was approximately $1.9 million and $1.3 million , respectively. With limited exception, the Company is no longer subject to examination by various U.S. and foreign taxing authorities for years before 2012. At this time, the Company believes that it is reasonably possible that unrecognized tax benefits of approximately $2.1 million may change within the next 12 months due to the expiration of statutory review periods and current examinations.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION PLANS	STOCK-BASED COMPENSATION PLANS As of December 31, 2015 , the Company maintains employee stock-based compensation plans for stock options, restricted stock, and incentive stock units as governed by the 2011 Stock Incentive Compensation Plan (the “2011 Plan”) and the 2000 Stock Incentive Plan, as amended (the “2000 Plan”). The 2011 Plan has a 10 year term through March 27, 2021 and as of December 31, 2015 the number of shares available for future grants under the 2011 Plan was 2,703,673 shares, which includes remaining shares to grant under the 2000 Plan. The 2011 Plan was approved by stockholders of Wabtec on May 11, 2011. The Company also maintains a 1995 Non-Employee Directors’ Fee and Stock Option Plan (“ the Directors Plan”). The Directors Plan, as amended, authorizes a total of 1,000,000 shares of Common Stock to be issued. Under the Directors Plan options issued become exercisable over a three -year vesting period and expire ten years from the date of grant and restricted stock issued under the plan vests one year from the date of grant. As compensation for directors’ fees for the years ended December 31, 2015 , 2014 and 2013 , the Company issued a total of 11,256 , 12,704 and 17,875 shares of restricted stock to non-employee directors. The total number of shares issued under the plan as of December 31, 2015 was 847,720 shares. No units may be made under the Directors Plan subsequent to October 31, 2016 . Stock-based compensation expense for all of the plans was $26.0 million , $26.1 million and $24.1 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. The Company recognized associated tax benefits related to the stock-based compensation plans of $15.3 million , $7.6 million and $7.9 million for the respective periods. Included in the stock-based compensation expense for 2015 above is $2.2 million of expense related to stock options, $6.2 million related to non-vested restricted stock, $2.5 million related to restricted stock units, $13.5 million related to incentive stock units and $1.1 million related to units issued for Directors’ fees. At December 31, 2015 , unamortized compensation expense related to those stock options, non-vested restricted shares and incentive stock units expected to vest totaled $23.8 million and will be recognized over a weighted average period of 1.1 years . Stock Options Stock options are granted to eligible employees and directors at the fair market value, which is the average of the high and low Wabtec stock price on the date of grant. Under the 2011 Plan and the 2000 Plan, options become exercisable over a four years vesting period and expire 10 years from the date of grant. The following table summarizes the Company’s stock option activity and related information for the 2011 Plan, the 2000 Plan and Directors Plan for the years ended December 31: Options Weighted Weighted Average Aggregate Outstanding at December 31, 2012 1,465,678 $ 20.24 6.3 $ 34,487 Granted 116,392 48.29 3,024 Exercised (344,806 ) 14.98 (20,444 ) Canceled (4,402 ) 26.61 (210 ) Outstanding at December 31, 2013 1,232,862 $ 24.36 6.1 $ 61,530 Granted 81,552 73.20 1,116 Exercised (163,786 ) 20.37 (10,895 ) Canceled (3,070 ) 52.73 (105 ) Outstanding at December 31, 2014 1,147,558 $ 28.33 5.5 $ 67,205 Granted 84,675 87.35 1,375 Exercised (124,156 ) 26.70 (5,516 ) Canceled (10,754 ) 65.22 (64 ) Outstanding at December 31, 2015 1,097,323 $ 32.70 4.8 $ 42,154 Exercisable at December 31, 2015 863,157 $ 23.71 4.0 $ 40,920 Options outstanding at December 31, 2015 were as follows: Number of Weighted Weighted Number of Weighted Average Range of exercise prices Outstanding Outstanding Life Exercisable Exercisable Under $15.00 206,500 $ 14.50 3.1 206,500 $ 14.50 15.00 - 23.00 345,048 18.20 2.9 345,048 18.20 23.00 - 30.00 165,617 28.74 4.8 165,617 28.74 30.00 - 38.00 119,805 35.27 6.1 81,956 35.22 Over 38.00 260,353 67.72 8.0 64,036 55.43 1,097,323 $ 32.70 863,157 $ 23.71 The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions: For the year ended December 31, 2015 2014 2013 Dividend yield 0.14 % 0.11 % 0.21 % Risk-free interest rate 1.8 % 2.2 % 1.4 % Stock price volatility 27.3 % 33.0 % 43.8 % Expected life (years) 5.0 5.0 5.0 Weighted average fair value of options granted during the year $ 24.41 $ 22.82 $ 17.60 The dividend yield is based on the Company’s dividend rate and the current market price of the underlying common stock at the date of grant. Expected life in years is determined from historical stock option exercise data. Expected volatility is based on the historical volatility of the Company’s stock. The risk-free interest rate is based on the 7 years U.S. Treasury bond rates for the expected life of the option. Restricted Stock and Incentive Stock Beginning in 2006 the Company adopted a restricted stock program. As provided for under the 2011 and 2000 Plans, eligible employees are granted restricted stock that generally vests over four years from the date of grant. Under the Directors Plan, restricted stock units vest one year from the date of grant. In addition, the Company has issued incentive stock units to eligible employees that vest upon attainment of certain cumulative three -year performance goals. Based on the Company’s performance for each three year period then ended, the incentive stock units can vest and be awarded ranging from 0% to 200% of the initial incentive stock units granted. The incentive stock units included in the table below represent the number of shares that are expected to vest based on the Company’s estimate for meeting those established performance targets. As of December 31, 2015 , the Company estimates that it will achieve 123% , 134% and 101% for the incentive stock units expected to vest based on performance for the three year periods ending December 31, 2015 , 2016 , and 2017 , respectively, and has recorded incentive compensation expense accordingly. If our estimate of the number of these stock units expected to vest changes in a future accounting period, cumulative compensation expense could increase or decrease and will be recognized in the current period for the elapsed portion of the vesting period and would change future expense for the remaining vesting period. Compensation expense for the non-vested restricted stock and incentive stock units is based on the closing price of the Company’s common stock on the date of grant and recognized over the applicable vesting period. The following table summarizes the restricted stock activity and related information for the 2011 Plan, the 2000 Plan, and Directors Plan, and incentive stock units activity and related information for the 2011 Plan and the 2000 Plan with related information for the years ended December 31: Restricted Incentive Weighted Outstanding at December 31, 2012 546,774 1,329,078 $ 26.69 Granted 173,887 200,090 48.62 Vested (204,494 ) (570,918 ) 20.86 Adjustment for incentive stock awards expected to vest — 91,694 33.49 Canceled (6,038 ) (6,350 ) 26.98 Outstanding at December 31, 2013 510,129 1,043,594 $ 35.27 Granted 150,886 140,240 73.68 Vested (218,502 ) (458,536 ) 29.83 Adjustment for incentive stock awards expected to vest — 74,680 47.56 Canceled (3,970 ) (8,370 ) 48.50 Outstanding at December 31, 2014 438,543 791,608 $ 47.97 Granted 113,945 126,050 87.90 Vested (182,776 ) (433,932 ) 37.76 Adjustment for incentive stock awards expected to vest — 65,666 57.57 Canceled (12,827 ) (7,754 ) 67.05 Outstanding at December 31, 2015 356,885 541,638 $ 65.89

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS ASC 820 “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value and explains the related disclosure requirements. ASC 820 indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model. Valuation Hierarchy. ASC 820 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following table provides the liabilities carried at fair value measured on a recurring basis as of December 31, 2015 , which are included in other current liabilities on the Consolidated Balance sheet: Fair Value Measurements at December 31, 2015 Using Total Carrying Quoted Prices in Significant Other Significant In thousands 2015 (Level 1) (Level 2) (Level 3) Interest rate swap agreements 4,474 — 4,474 — Total $ 4,474 $ — $ 4,474 $ — The following table provides the liabilities carried at fair value measured on a recurring basis as of December 31, 2014 , which are included in other current liabilities on the Consolidated Balance sheet: Fair Value Measurements at December 31, 2014 Using Total Carrying Quoted Prices in Significant Other Significant In thousands 2014 (Level 1) (Level 2) (Level 3) Interest rate swap agreements 3,351 — 3,351 — Total $ 3,351 $ — $ 3,351 $ — To reduce the impact of interest rate changes on a portion of its variable-rate debt, the Company entered into interest rate swaps which effectively converted a portion of the debt from variable to fixed-rate borrowings during the term of the swap contracts. For certain derivative contracts whose fair values are based upon trades in liquid markets, such as interest rate swaps, valuation model inputs can generally be verified and valuation techniques do not involve significant management judgment. The fair values of such financial instruments are generally classified within Level 2 of the fair value hierarchy. As a result of our global operating activities the Company is exposed to market risks from changes in foreign currency exchange rates, which may adversely affect our operating results and financial position. When deemed appropriate, the Company minimizes these risks through entering into foreign currency forward contracts. The foreign currency forward contracts are valued using broker quotations, or market transactions in either the listed or over-the counter markets. As such, these derivative instruments are classified within level 2. The Company’s cash and cash equivalents are highly liquid investments purchased with an original maturity of three months or less and are considered Level 1 on the fair value valuation hierarchy. The fair value of cash and cash equivalents approximated the carrying value at December 31, 2015 and December 31, 2014 . The Company’s defined benefit pension plan assets consist primarily of equity security funds, debt security funds and temporary cash and cash equivalent investments. Generally, all plan assets are considered Level 2 based on the fair value valuation hierarchy. These investments are comprised of a number of investment funds that invest in a diverse portfolio of assets including equity securities, corporate and governmental bonds, and money markets. Trusts are valued at the net asset value (“NAV”) as determined by their custodian. NAV represent the accumulation of the unadjusted quoted close prices on the reporting date for the underlying investments divided by the total shares outstanding at the reporting dates. The 2013 Notes are considered Level 2 based on the fair value valuation hierarchy. The estimated fair values and related carrying values of the Company’s financial instruments are as follows: December 31, 2015 December 31, 2014 Carry Fair Carry Fair In thousands Value Value Value Value Interest rate swap agreements $ 4,474 $ 4,474 $ 3,351 $ 3,351 4.375% Senior Notes 250,000 254,075 250,000 260,000 The fair value of the Company’s interest rate swap agreements and the 2013 Notes were based on dealer quotes and represent the estimated amount the Company would pay to the counterparty to terminate the agreement.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The Company is subject to a variety of environmental laws and regulations governing discharges to air and water, the handling, storage and disposal of hazardous or solid waste materials and the remediation of contamination associated with releases of hazardous substances. The Company believes its operations currently comply in all material respects with all of the various environmental laws and regulations applicable to our business; however, there can be no assurance that environmental requirements will not change in the future or that we will not incur significant costs to comply with such requirements. Under terms of the purchase agreement and related documents for the 1990 Acquisition, American Standard, Inc., now known as Trane (“Trane”), has indemnified the Company for certain items including, among other things, certain environmental claims the Company asserted prior to 2000. If Trane was unable to honor or meet these indemnifications, the Company would be responsible for such items. In the opinion of Management, Trane currently has the ability to meet its indemnification obligations. Claims have been filed against the Company and certain of its affiliates in various jurisdictions across the United States by persons alleging bodily injury as a result of exposure to asbestos-containing products. Most of these claims have been made against our wholly owned subsidiary, Railroad Friction Products Corporation (“RFPC”), and are based on a product sold by RFPC prior to the time that the Company acquired any interest in RFPC. Most of these claims, including all of the RFPC claims, are submitted to insurance carriers for defense and indemnity or to non-affiliated companies that retain the liabilities for the asbestos-containing products at issue. We cannot, however, assure that all these claims will be fully covered by insurance or that the indemnitors or insurers will remain financially viable. Our ultimate legal and financial liability with respect to these claims, as is the case with other pending litigation, cannot be estimated. It is Management’s belief that the potential range of loss for asbestos-related bodily injury cases is not reasonably determinable at present due to a variety of factors, including: (1) the asbestos case settlement history of the Company’s wholly owned subsidiary, RFPC; (2) the unpredictable nature of personal injury litigation in general; and (3) the uncertainty of asbestos litigation in particular. Despite this uncertainty, and although the results of the Company’s operations and cash flows for any given period could be adversely affected by asbestos-related lawsuits, Management believes that the final resolution of the Company’s asbestos-related cases will not be material to the Company’s overall financial position, results of operations and cash flows. In general, this belief is based upon: (1) Wabtec’s and RFPC’s history of settlements and dismissals of asbestos-related cases to date; (2) the inability of many plaintiffs to establish any exposure or causal relationship to RFPC’s product; and (3) the inability of many plaintiffs to demonstrate any identifiable injury or compensable loss. More specifically, as to RFPC, Management’s belief that any losses due to asbestos-related cases would not be material is also based on the fact that RFPC owns insurance which provides coverage for asbestos-related bodily injury claims. To date, RFPC’s insurers have provided RFPC with defense and indemnity in these actions. The overall number of new claims being filed against RFPC has dropped significantly in recent years; however, these new claims, and all previously filed claims, may take a significant period of time to resolve. As to Wabtec and its divisions, Management’s belief that asbestos-related cases will not have a material impact is also based on its position that it has no legal liability for asbestos-related bodily injury claims, and that the former owners of Wabtec’s assets retained asbestos liabilities for the products at issue. To date, Wabtec has been able to successfully defend itself on this basis, including two arbitration decisions and a judicial opinion, all of which confirmed Wabtec’s position that it did not assume any asbestos liabilities from the former owners of certain Wabtec assets. Although Wabtec has incurred defense and administrative costs in connection with asbestos bodily injury actions, these costs have not been material, and the Company has no information that would suggest these costs would become material in the foreseeable future. From time to time the Company is involved in litigation relating to claims arising out of its operations in the ordinary course of business. As of the date hereof, the Company is involved in no litigation that the Company believes will have a material adverse effect on its financial condition, results of operations or liquidity.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Wabtec has two reportable segments—the Freight Segment and the Transit Segment. The key factors used to identify these reportable segments are the organization and alignment of the Company’s internal operations, the nature of the products and services, and customer type. The business segments are: Freight Segment primarily manufactures and services components for new and existing freight cars and locomotives, builds new switcher locomotives, rebuilds freight locomotives, supplies railway electronics, positive train control equipment, signal design and engineering services, and provides related heat exchange and cooling systems. Customers include large, publicly traded railroads, leasing companies, manufacturers of original equipment such as locomotives and freight cars, and utilities. Transit Segment primarily manufactures and services components for new and existing passenger transit vehicles, typically subway cars and buses, builds new commuter locomotives and refurbishes subway cars. Customers include public transit authorities and municipalities, leasing companies, and manufacturers of subway cars and buses around the world. The Company evaluates its business segments’ operating results based on income from operations. Corporate activities include general corporate expenses, elimination of intersegment transactions, interest income and expense and other unallocated charges. Since certain administrative and other operating expenses and other items have not been allocated to business segments, the results in the following tables are not necessarily a measure computed in accordance with generally accepted accounting principles and may not be comparable to other companies.

SUMMARY OF SIGNIFICANT ACCOUN33

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Principles of Consolidation	The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. Such statements have been prepared in accordance with U.S. generally accepted accounting principles. Sales between subsidiaries are billed at prices consistent with sales to third parties and are eliminated in consolidation.
Capital Structure	On May 14, 2013, our stockholders approved an amendment to our Amended and Restated Certificate of Incorporation to increase the number of authorized shares of our common stock to 200.0 million shares. In addition, on May 14, 2013, our Board of Directors approved a two -for-one split of the Company’s issued and outstanding common stock in the form of a 100% stock dividend. The increase in the authorized shares and the stock split became effective on May 14, 2013 and June 11, 2013, respectively. The Company issued approximately 66.2 million shares of its common stock as a result of the two -for-one stock split. The par value of the Company’s common stock remained unchanged at $0.01 per share. Information regarding shares of common stock (except par value per share), retained earnings, and net income per common share attributable to Wabtec shareholders for all periods presented reflects the two -for-one split of the Company’s common stock. The number of shares of the Company’s common stock issuable upon exercise of outstanding stock options and vesting of other stock-based awards was proportionally increased, and the exercise price per share thereof was proportionally decreased, in accordance with the terms of the stock incentive plans.
Cash Equivalents	Cash equivalents are highly liquid investments purchased with an original maturity of three months or less.
Allowance for Doubtful Accounts	The allowance for doubtful accounts receivable reflects our best estimate of probable losses inherent in our receivable portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. The allowance for doubtful accounts was $5.6 million and $6.3 million as of December 31, 2015 and 2014 , respectively.
Inventories	Inventories are stated at the lower of cost or market. Cost is determined under the first-in, first-out (FIFO) method. Inventory costs include material, labor and overhead.
Property, Plant and Equipment	Property, plant and equipment additions are stated at cost. Expenditures for renewals and improvements are capitalized. Expenditures for ordinary maintenance and repairs are expensed as incurred. The Company provides for book depreciation principally on the straight-line method. Accelerated depreciation methods are utilized for income tax purposes.
Leasing Arrangements	The Company conducts a portion of its operations from leased facilities and finances certain equipment purchases through lease agreements. In those cases in which the lease term approximates the useful life of the leased asset or the lease meets certain other prerequisites, the leasing arrangement is classified as a capital lease. The remaining arrangements are treated as operating leases.
Intangible Assets	Goodwill and other intangible assets with indefinite lives are not amortized. Other intangibles (with definite lives) are amortized on a straight-line basis over their estimated economic lives. Amortizable intangible assets are reviewed for impairment when indicators of impairment are present. The Company tests goodwill and indefinite-lived intangible assets for impairment at least annually. The Company performs its annual impairment test during the fourth quarter after the annual forecasting process is completed, and also tests for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Periodically, Management of the Company assesses whether or not an indicator of impairment is present that would necessitate an impairment analysis be performed. For 2015, the Company opted to perform a qualitative goodwill assessment and determined that step two was not necessary. In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we assess relevant events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of relevant events and circumstances and how these may impact a reporting unit’s fair value or carrying amount involve significant judgments and assumptions. The judgment and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Wabtec specific events and share price trends and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact. If our qualitative assessment concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company then performs a two-step impairment test. In the first step of the quantitative assessment, our assets and liabilities, including existing goodwill and other intangible assets, are assigned to the identified reporting units to determine the carrying value of the reporting units. The Company reviews goodwill for impairment at the reporting unit level. The Company prepares its goodwill impairment analysis by comparing the estimated fair value of each reporting unit, using an income approach (a discounted cash flow model) as well as a market approach, with its carrying value. The income approach and the market approach are equally weighted in arriving at fair value, which the Company has applied consistently. The discounted cash flow model requires several assumptions including future sales growth, EBIT (earnings before interest and taxes) margins and capital expenditures for the reporting units. The discounted cash flow model also requires the use of a discount rate and a terminal revenue growth rate (the revenue growth rate for the period beyond the three years forecasted by the reporting units), as well as projections of future operating margins. The market approach requires several assumptions including EBITDA (earnings before interest, taxes, depreciation and amortization) multiples for comparable companies that operate in the same markets as the Company’s reporting units.
Warranty Costs	Warranty costs are accrued based on Management’s estimates of repair or upgrade costs per unit and historical experience. Warranty expense was $35.4 million , $34.1 million and $22.9 million for 2015 , 2014 and 2013 , respectively. Accrued warranty was $92.1 million and $87.8 million at December 31, 2015 and 2014 , respectively.
Income Taxes	Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws. The provision for income taxes includes federal, state and foreign income taxes.
Stock-Based Compensation	The Company recognizes compensation expense for stock-based compensation based on the grant date fair value amortized ratably over the requisite service period following the date of grant.
Financial Derivatives and Hedging Activities	The Company has entered into foreign currency forward contracts to reduce the impact of changes in currency exchange rates. Foreign currency forward contracts are agreements with a counterparty to exchange two distinct currencies at a set exchange rate for delivery on a set date at some point in the future. There is no exchange of funds until the delivery date. At the delivery date the Company can either take delivery of the currency or settle on a net basis. At December 31, 2015 , the Company had no material foreign currency forward contracts. To reduce the impact of interest rate changes on a portion of it's variable-rate debt, the Company has entered into two forward starting interest rate swap agreement with a notional value of $150 million . As of December 31, 2015 , the Company has recorded a current liability of $4.5 million and a corresponding offset in accumulated other comprehensive loss of $2.7 million , net of tax, related to these agreements. For further information regarding the forward starting interest rate swap agreements, see Footnote 9.
Foreign Currency Translation	Assets and liabilities of foreign subsidiaries, except for the Company’s Mexican operations whose functional currency is the U.S. Dollar, are translated at the rate of exchange in effect on the balance sheet date while income and expenses are translated at the average rates of exchange prevailing during the period. Foreign currency gains and losses resulting from transactions, and the translation of financial statements are recorded in the Company’s consolidated financial statements based upon the provisions of Accounting Standards Codification (“ASC”) 830, “Foreign Currency Matters.” The effects of currency exchange rate changes on intercompany transactions and balances of a long-term investment nature are accumulated and carried as a component of accumulated other comprehensive loss. The effects of currency exchange rate changes on intercompany transactions that are denominated in a currency other than an entity’s functional currency are charged or credited to earnings. Foreign exchange transaction losses recognized in other (expense) income, net were $4.7 million , $2.4 million and $3.5 million for 2015 , 2014 and 2013 , respectively.
Noncontrolling Interests	In accordance with ASC 810, the Company has classified noncontrolling interests as equity on our condensed consolidated balance sheets as of December 31, 2015 and 2014 . Net income attributable to noncontrolling interests for the years ended December 31, 2015 , 2014 and 2013 was not material.
Other Comprehensive Income (Loss)	Comprehensive income (loss) is defined as net income and all other non-owner changes in shareholders’ equity. The Company’s accumulated other comprehensive income consists of foreign currency translation adjustments, foreign currency hedges, foreign exchange contracts, interest rate swaps, and pension and post retirement related adjustments.
Revenue Recognition	Revenue is recognized in accordance with ASC 605 “Revenue Recognition,” The Company recognized revenue when the following criteria are met: 1) persuasive evidence of an arrangement exists; 2) delivery has occurred; 3) an established sales price has been set with the customer; 4) collection of the sale revenue from the customer is reasonably assured; and 5) no contingencies exist. Delivery is considered to have occurred when the customer assumes the risk and rewards of ownership. The Company estimates and records provisions for quantity rebates and sales returns and allowances as an offset to revenue in the same period the related revenue is recognized, based upon its experience. These items are included as a reduction in deriving net sales. In general, the Company recognizes revenues on long-term contracts based on the percentage of completion method of accounting. The units-of-delivery method or other input-based or output-based measures, as appropriate, are used to measure the progress toward completion of individual contracts. Contract revenues and cost estimates are reviewed and revised quarterly at a minimum and adjustments are reflected in the accounting period as such amounts are determined. Provisions are made currently for estimated losses on uncompleted contracts. Unbilled accounts receivables were $103.8 million and $187.8 million , customer deposits were $106.1 million and $111.8 million , and provisions for loss contracts were $11.8 million and $7.1 million at December 31, 2015 and 2014 , respectively. Certain pre-production costs relating to long-term production and supply contracts have been deferred and will be recognized over the life of the contracts. Deferred pre-production costs were $30.3 million and $24.9 million at December 31, 2015 and 2014 , respectively.
Significant Customers and Concentrations of Credit Risk	The Company’s trade receivables are from rail and transit industry original equipment manufacturers, Class I railroads, railroad carriers and commercial companies that utilize rail cars in their operations, such as utility and chemical companies. No one customer accounted for more than 10% of the Company’s consolidated net sales in 2015 , 2014 or 2013 .
Shipping and Handling Fees and Costs	All fees billed to the customer for shipping and handling are classified as a component of net revenues. All costs associated with shipping and handling is classified as a component of cost of sales.
Research and Development	Research and development costs are charged to expense as incurred. For the years ended December 31, 2015 , 2014 and 2013 , the Company incurred costs of approximately $71.2 million , $61.9 million , and $46.3 million , respectively.
Employees	As of December 31, 2015 , approximately 30% of the Company’s workforce was covered by collective bargaining agreements. These agreements are generally effective from 2015 through 2017. Agreements expiring in 2015 cover approximately 26% of the Company’s workforce.
Earnings Per Share	Basic and diluted earnings per common share is computed in accordance with ASC 260 “Earnings Per Share.” Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and included in the computation of earnings per share pursuant to the two-class method included in ASC 260-10-55. (See Note 12 “Earnings Per Share” included herein)
Use of Estimates	The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from the estimates. On an ongoing basis, Management reviews its estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.
Recent Accounting Pronouncements	In April 2015, the FASB issued Accounting Standards Update No. 2015-3, “Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-3”) which changes the presentation of debt issuance costs in financial statements to present such costs as a direct deduction from the related debt liability rather than as an asset. ASU 2015-3 will become effective for public companies during interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this standard is not expected to have a material impact to the financial statements. The Company will make the required changes in the first quarter of 2016. In May 2014, the FASB issued ASU no. 2014-9, “Revenue from Contract with Customers.” The ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Board voted to propose that the standard would take effect for reporting periods beginning after December 15, 2017 and that early adoption would be allowed as of the original effective date. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU No. 2015-17, “Balance Sheet Classification of Deferred Taxes” as part of their simplification initiatives. The update requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The update is effective for financial periods beginning after December 15, 2017; however, early application is permitted. The adoption of this standard is not expected to have a material impact to the financial statements.

Pension Plan Assets by Asset Category	Pension Plan Assets The Company has established formal investment policies for the assets associated with our pension plans. Objectives include maximizing long-term return at acceptable risk levels and diversifying among asset classes. Asset allocation targets are based on periodic asset liability study results which help determine the appropriate investment strategies. The investment policies permit variances from the targets within certain parameters. The plan assets consist primarily of equity security funds, debt security funds, and temporary cash and cash equivalent investments. The assets held in these funds are generally actively managed and are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. Generally, all plan assets are considered Level 2 based on the fair value valuation hierarchy (See Note 18 “Fair Value Measurement” included herein). Plan assets by asset category at December 31, 2015 and 2014 are as follows: U.S. International In thousands 2015 2014 2015 2014 Pension Plan Assets Equity security funds $ 20,275 $ 20,696 $ 87,321 $ 99,715 Debt security funds and other 16,441 20,034 77,173 78,510 Cash and cash equivalents 924 773 3,575 4,029 Fair value of plan assets $ 37,640 $ 41,503 $ 168,069 $ 182,254
