TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

Under this shelf registration process, we may sell from time to time any securities described in this prospectus, individually or in any combination, in one or more offerings. This prospectus provides you with a general description of the securities we may offer. You should assume that the information appearing in this prospectus is accurate only as of the date of this prospectus. Our business, financial condition, results of operations and prospects may change after that date. Each time we sell securities under this prospectus, we will provide a prospectus supplement that will contain or incorporate by reference specific information about the terms of that offering. Each prospectus supplement also may add, update or change information contained in this prospectus. We urge you to read both this prospectus and any prospectus supplement, together with the additional information described below under "Where You Can Find More Information."

Neither the delivery of this prospectus nor any sale made under this prospectus shall under any circumstances create any implication that there has been no change in our affairs since the date of this prospectus or that the information contained or incorporated by reference in this prospectus is correct as of any time subsequent to the date of such information. This prospectus does not constitute an offer to sell or a solicitation of an offer to buy any securities by anyone in any jurisdiction in which such offer or solicitation is not authorized or in which the person making such offer or solicitation is not qualified to do so or to any person to whom it is unlawful to make such offer or solicitation.

This summary does not contain all of the information that you should consider before investing in any securities being offered by this prospectus. We urge you to carefully read this entire prospectus, the documents incorporated by reference into this prospectus and any applicable prospectus supplement relating to the securities that you propose to buy, especially any description of investment risks that we may include in any applicable prospectus supplement or in documents incorporated by reference in this prospectus. References to "Wabtec," the "registrant," "we," "our," "us" and similar terms mean Westinghouse Air Brake Technologies Corporation and its consolidated subsidiaries, unless the context requires otherwise.

RISK FACTORS

Investing in our securities involves risks. Before deciding whether to purchase any of our securities, you should carefully consider the risks involved in an investment in our securities, as set forth in Item 1A, Risk Factors, in our Annual Report on Form 10-K for our fiscal year ended December 31, 2025, as updated in our subsequent Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q, and the other risks described in any applicable prospectus supplement or in any of the documents incorporated by reference in this prospectus. The risks and uncertainties that we discuss in any document incorporated by reference in this prospectus are those that we believed as of the date of the document to be risks which may materially affect our company. Additional risks and uncertainties not then known to us or that we then believed to be immaterial also may materially and adversely affect our business, financial condition and results of operations.

FORWARD-LOOKING STATEMENTS

You should carefully review the information contained in or incorporated by reference into this prospectus. In this prospectus and the documents incorporated herein by reference, statements that are not reported financial results or other historical information are "forward-looking statements." Forward-looking statements give current expectations or forecasts of future events and are not guarantees of future performance. They are based on our management's expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements.

You can identify these forward-looking statements by the fact that they do not relate strictly to historic or current facts. They use words such as "anticipates," "believes," "continues," "could," "endeavors," "estimates," "expects," "forecast," "intends," "may," "outlook," "potential," "predicts," "projects," "should," "targets," "will," "will likely result," "would," and similar expressions in connection with any discussion of future operating or financial performance.

We cannot guarantee that any forward-looking statements will be realized, although we believe that we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and assumptions that may prove to be inaccurate. Among others, the factors discussed in the "Risk Factors" sections of our Annual Report on Form 10-K for our fiscal year ended December 31, 2025 and any of our subsequently filed Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K could cause actual results to differ from those in forward-looking statements included in or incorporated by reference into this prospectus or that we otherwise make. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, among others:

Economic and industry conditions

Operating factors

Competitive factors

Political/governmental factors

Natural hazards / health crises

Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove to be inaccurate, actual results could vary materially from those anticipated, estimated or projected. You should bear this in mind as you consider, and should not place undue reliance on, any forward-looking statements.

We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by law. You are advised, however, to consider any additional disclosures that we may make on related subjects in future filings with the SEC. You should understand that it is not possible to predict or identify all factors that could cause our actual results to differ. Consequently, you should not consider any list of factors to be a complete set of all potential risks or uncertainties.

USE OF PROCEEDS

We intend to use the net proceeds from the sale of the securities for general corporate purposes, unless otherwise indicated in the applicable prospectus supplement relating to a specific issuance of securities. Our general corporate purposes include, but are not limited to, repayment, redemption or refinancing of debt, capital expenditures, investments in or loans to subsidiaries and joint ventures, funding of acquisitions, working capital, contributions to one or more of our pension plans, satisfaction of other obligations and repurchase of our outstanding debt or equity securities. Pending any such use, the net proceeds from the sale of the securities may be invested in short-term, investment grade, interest-bearing instruments. We will include a more detailed description of the use of proceeds of any specific offering in the applicable prospectus supplement relating to an offering of securities under this prospectus.

DESCRIPTION OF DEBT SECURITIES

The following is a general description of the debt securities that we may offer from time to time under this prospectus. The financial terms and other specific terms of the debt securities being offered will be described in a prospectus supplement relating to the issuance of those securities. Those terms may vary from the terms described here. Although the debt securities that we may offer include debt securities denominated in U.S. dollars, we also may choose to offer debt securities in any other currency, including the euro. Any debt securities issued by us may be guaranteed by one or more of our direct and indirect subsidiaries named as co-registrants in the registration statement of which this prospectus is a part (collectively, the "Subsidiary Guarantors").

The debt securities are governed by documents called "indentures." The indentures are contracts between us and a financial institution acting as the trustee. The trustee has two main roles. First, under certain circumstances, the trustee can enforce your rights against us if we default. There are some limitations on the extent to which the trustee may act on your behalf, as described under "-Events of Default-Remedies If an Event of Default Occurs." Second, the trustee performs certain administrative duties for us.

Because this section is a summary, it does not describe every aspect of the debt securities that we may offer pursuant to this prospectus. This summary also is subject to and qualified by reference to the description of the particular terms of the debt securities, the relevant indenture and any relevant supplemental indenture described in the related prospectus supplement, including definitions used in the relevant indenture and any relevant supplemental indenture. The particular terms of the debt securities that we may offer under this prospectus, the relevant indenture and any relevant supplemental indenture may vary from the terms described below.

General

The debt securities that we may offer under this prospectus will be either senior debt securities or subordinated debt securities. We may issue senior debt securities under one or more senior indentures among us, any applicable Subsidiary Guarantor and U.S. Bank Trust Company, National Association, as series trustee, including an existing Indenture, dated as of August 8, 2013, between us and Computershare Trust Company, National Association (as successor to Wells Fargo Bank, National Association), as original trustee, which we refer to in this prospectus as the existing indenture, and a supplemental indenture thereto as contemplated therein. Unless otherwise specified in the applicable prospectus supplement, U.S. Bank Trust Company, National Association will serve as trustee with respect to the senior debt securities issued pursuant to any such supplemental indenture to the existing indenture. In this prospectus, we refer to any indenture pursuant to which senior debt securities offered under this prospectus may be issued, including the existing indenture, as any such indenture may be supplemented, as a senior indenture. We may issue subordinated debt securities under one or more subordinated indentures among us, any applicable Subsidiary Guarantor and U.S. Bank Trust Company, National Association, as trustee. In this prospectus, we refer to any indenture pursuant to which subordinated debt securities offered under this prospectus may be issued, as any such indenture may be supplemented, as a subordinated indenture. Senior indentures and subordinated indentures are sometimes referred to collectively in this prospectus as indentures.

The existing indenture is, and any other indenture will be, governed by New York law. Copies of the existing indenture and forms of a senior indenture and a subordinated indenture pursuant to which we may issue debt securities that are offered under this prospectus have been filed as exhibits to the registration statement of which this prospectus is a part. See "Where You Can Find More Information" for information on how to obtain copies of these indentures.

We may offer the debt securities from time to time in as many distinct series as we may choose. All debt securities will be direct, unsecured obligations of ours. Any senior debt securities that we offer under this prospectus will have the same rank as all of our other unsecured and unsubordinated debt. Any subordinated debt securities that we offer under this prospectus will be subordinate in right of payment to our senior indebtedness. The existing indenture does not, and any other indenture may not, limit either the amount of debt that we may issue thereunder or the amount of other unsecured debt or other securities that we or our subsidiaries may issue.

Our primary sources of payment for our payment obligations under the debt securities will be revenues from our operations and investments and cash distributions from our subsidiaries. Our subsidiaries are separate and distinct legal entities and have no obligation whatsoever to pay any amounts due on debt securities issued by us or to make funds available to us, except to the extent that they have agreed to guarantee such obligations of ours. Our

subsidiaries' ability to pay dividends or make other payments or advances to us will depend upon their operating results and will be subject to applicable laws and contractual restrictions. The existing indenture does not, and any other indenture may not, restrict our subsidiaries from entering into agreements that prohibit or limit their ability to pay dividends or make other payments or advances to us.

To the extent that we must rely on cash from our subsidiaries to pay amounts due on the debt securities, the debt securities will be effectively subordinated to all liabilities, including their trade payables, of our subsidiaries (other than subsidiaries that guarantee the debt securities). This means that such subsidiaries may be required to pay all of their creditors in full before their assets are available to us. Even if we are recognized as a creditor of such subsidiaries, our claims would be effectively subordinated to any security interests in their assets and also could be subordinated to some or all other claims on their assets and earnings.

Other than the restrictions described below or any restrictions described in an applicable prospectus supplement, the existing indenture does not, and any other indenture and the debt securities that we may offer under this prospectus will not, contain any covenants or other provisions designed to protect holders of the debt securities if we participate in a highly leveraged transaction.

You should look in the applicable prospectus supplement for the following terms of the debt securities being offered:

In addition to the debt securities that we may offer pursuant to this prospectus, we may issue other debt securities in public or private offerings from time to time. These other debt securities may be issued under documentation that is not described in this prospectus, and those debt securities may contain provisions materially different from the provisions applicable to one or more issues of debt securities offered pursuant to this prospectus.

Debt Guarantees

Debt securities offered by us may be guaranteed by one or more of the Subsidiary Guarantors. The Subsidiary Guarantors are named as co-registrants in the registration statement of which this prospectus is a part. Any guarantee of debt securities offered by us will be set forth in the applicable indenture or a related supplemental indenture and described in an applicable prospectus supplement. The payment obligations of any Subsidiary Guarantor will rank equal in right of payment to all existing and future senior indebtedness of such Subsidiary Guarantor, senior in right of payment to all expressly subordinated indebtedness of such Subsidiary Guarantor, effectively subordinate to all existing and future secured indebtedness of such Subsidiary Guarantor to the extent of the value of the collateral securing such indebtedness, and structurally subordinate to all existing and future indebtedness and other liabilities of our non-guarantor subsidiaries (other than indebtedness and liabilities owed to such Subsidiary Guarantor).

Original Issue Discount

Any series of debt securities offered under this prospectus may be sold at a substantial discount below its stated principal amount, bearing no interest or bearing interest at a rate that at the time of issuance is below market rates. The federal income tax consequences and special considerations applicable to any series of debt securities generally will be described in the applicable prospectus supplement.

Restrictive Covenants

The existing indenture contains, and any other indenture may contain, certain covenants for the benefit only of holders of the debt securities governed by the applicable indenture. The covenants summarized below will apply to each series of debt securities issued pursuant to any of the indentures as long as any of those debt securities are outstanding, unless waived, amended or the applicable prospectus supplement states otherwise.

Payment. We will duly and punctually pay the principal of and premium, if any, and interest on the debt securities in accordance with the terms of such debt securities and the applicable indenture. Unless otherwise provided in the applicable prospectus supplement, at or before 10:00 a.m., New York City time, on the applicable payment date, redemption date or repurchase date, the Company shall deposit with the paying agent money sufficient to pay the principal of, and premium, if any, and interest on, the debt securities in accordance with the terms of such securities and the indenture.

Subject to the requirements of any applicable abandoned property laws, the trustee and the paying agent shall pay to the Company upon written request any money held by them for the payment of principal, premium (if any), or interest on any debt security that remains unclaimed for two years after the date upon which such payment shall have become due. After payment to the Company, the holder of that debt security must look to the Company for payment as general creditors, unless an applicable abandoned property law designates another Person (as defined below), and all liability of the trustee and the paying agent with respect to such money shall cease.

Merger and Consolidation. We may not consolidate with or merge into any other person or sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of our assets to any individual, corporation, partnership, joint venture, association, limited liability company, joint-stock company, trust, unincorporated organization or any other entity, including any government or any agency or political subdivision thereof (each, a "Person"), unless:

Upon such a succession described in clause (ii) of the first bullet above and compliance with the second and third bullets above, we will be relieved from any further obligations under the applicable indenture.

Waiver of Certain Covenants. Unless otherwise provided in an applicable prospectus supplement, we may, with respect to the debt securities of any series, omit to comply with any covenant provided in the terms of those debt securities if, before the time for such compliance, holders of at least a majority in principal amount of the outstanding debt securities of that series waive such compliance in that instance or generally.

Events of Default

You will have special rights if an Event of Default occurs and is not cured, as described later in this subsection. Unless described otherwise in an applicable prospectus supplement, the term "Event of Default" means any of the following with respect to an issue of debt securities offered under this prospectus:

Remedies If an Event of Default Occurs. Unless provided otherwise in an applicable prospectus supplement, if an Event of Default, other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization, has occurred and continues with respect to an issue of debt securities, the trustee or the holders of at

least 25% in principal amount of the debt securities of the affected series may require us to pay immediately the principal amount of all of the debt securities of the affected series plus accrued and unpaid interest on such securities. This is called a "declaration of acceleration of maturity." If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization has occurred and continues with respect to an issue of debt securities, the principal amount of all of the debt securities of the affected series plus accrued and unpaid interest on such securities will become immediately due and payable without any action on the part of the trustee or the holders of such debt securities. Under some circumstances, a declaration of acceleration of maturity may be rescinded and annulled by the holders of a majority in principal amount of the debt securities of that series.

The trustee under the existing indenture generally is not, and the trustee under any other indenture generally will not be, required to take any action under that indenture at the request of any holders unless one or more of the holders has provided to the trustee security or indemnity reasonably satisfactory to it.

The holders of a majority in principal amount of the outstanding debt securities of the relevant series may direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, provided that (i) such direction is not in conflict with any rule of law or with the applicable indenture, (ii) the trustee may take any other action deemed proper by the trustee which is not inconsistent with that direction and (iii) the trustee has the right to decline to follow the direction if the trustee in good faith determines that the proceeding so directed would expose the trustee to personal liability or that it will not be adequately indemnified against the costs, expenses and liabilities which might be incurred by it in complying with such direction.

The holders of a majority in principal amount of the outstanding debt securities of the relevant series may, on behalf of the holders of all of the debt securities of that series, waive certain past defaults under the applicable indenture with respect to that series and its consequences.

If an Event of Default occurs and is continuing regarding a series of debt securities, the applicable trustee may use any sums that it holds under the relevant indenture for its own reasonable compensation and expenses incurred prior to paying the holders of debt securities of that series.

Before any holder of any series of debt securities may pursue any remedy under the applicable indenture, except enforcement of any overdue payment regarding a series of debt securities, the holders of at least 25% in principal amount of the outstanding debt securities of that series must request the trustee to take action by giving the trustee a written notice of a continuing Event of Default for such series of debt securities. Holders must also furnish to the trustee indemnity reasonably satisfactory to it against costs, expenses and liabilities which might be incurred by the trustee for taking such action. The trustee must also fail to act for a period of 60 days after receipt of notice and furnishing of indemnity and, during that 60-day period, the holders of a majority in principal amount of the outstanding debt securities of such series must not give the trustee a direction inconsistent with the request.

"Street Name" and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the applicable trustee and to make or cancel a declaration of acceleration.

We will furnish every year to the trustee under each indenture a written statement of certain of our officers certifying, among other things, that, to their knowledge, we are in compliance with that indenture and the debt securities offered pursuant to that indenture, or else specifying any default.

An Event of Default regarding one series of debt securities issued under an indenture is not necessarily an Event of Default regarding any other series of debt securities issued under that indenture or otherwise.

Satisfaction and Discharge; Defeasance and Covenant Defeasance

The following discussion of satisfaction and discharge, defeasance and covenant defeasance will be applicable to a series of debt securities only if we choose to have them apply to that series. If we do so choose, we will state that in the applicable prospectus supplement.

Satisfaction and Discharge. Each indenture will be satisfied and discharged with respect to a particular series of debt securities issued under that indenture if:

notice of redemption by the trustee in our name and at our expense, and, in any such case, we irrevocably deposit with the trustee, as funds in trust for such purpose, cash, certain U.S. government obligations maturing as to principal and interest at such times and in such amounts as will ensure the availability of cash, or a combination of cash and such U.S. government obligations, in an amount sufficient (in the case of U.S. government obligations, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification) to pay and discharge the entire indebtedness for principal of and interest to the date of such deposit (in the case of debt securities which have become due and payable) or for principal, premium, if any, and interest on such debt securities to the date of maturity or redemption, provided that in either case we have paid all other sums payable under that indenture. In addition, we must deliver an officers' certificate and an opinion of counsel to the trustee stating that all conditions precedent to satisfaction and discharge of the indenture with respect to such series of debt securities have been satisfied.

Legal Defeasance and Covenant Defeasance. The existing indenture provides, and any other indenture will provide, if such provision is made applicable to the debt securities of a series issued under that indenture, that, upon the deposit with the trustee (or other qualifying trustee), as funds in trust for such purpose, of cash or certain U.S. government obligations maturing as to principal and interest at such times and in such amounts as will ensure the availability of cash, or a combination of cash and such U.S. government obligations, in an amount sufficient (in the case of U.S. government obligations, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification) to pay the principal of and premium (if any) and interest on such debt securities, on the scheduled due dates:

In the case of legal defeasance or covenant defeasance, a trust may only be established if, among other things, no default or event of default has occurred and is continuing on the date of deposit and we have delivered to the trustee an opinion of counsel (as specified in the applicable indenture) or, in the case of covenant defeasance, an opinion of counsel or a binding tax ruling, in each case to the effect that the holders of the debt securities affected thereby will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of legal defeasance described above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable federal income tax law (including regulations) occurring after the date of the applicable indenture. We also will deliver to the trustee an officers' certificate and an opinion of counsel, each stating that all conditions precedent provided for or relating to the legal defeasance or covenant defeasance, as the case may be, have been complied with.

Modification and Waiver

The existing indenture contains, and any other indenture may contain, provisions permitting us and the trustee to modify that indenture or enter into or modify any supplemental indenture without the consent of the holders of the debt securities of a particular series in the following circumstances:

We and the trustee under an indenture may otherwise modify that indenture or any supplemental indenture relating to that indenture with the consent of the holders of at least a majority in aggregate principal amount of each series of debt securities affected thereby at the time outstanding, except that no such modifications shall, without the consent of the holder of each debt security affected thereby:

With respect to any vote of holders of a series of debt securities, we will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding debt securities that are entitled to vote or take other action under the applicable indenture.

"Street Name" and other indirect holders should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indenture or debt securities or request a waiver.

Subordinated Debt Securities

Although the existing indenture and the forms of senior indenture and subordinated indenture filed as exhibits to the registration statement of which this prospectus is a part are generally similar and many of the provisions discussed above pertain to both senior and subordinated debt securities, there are certain substantive differences between the senior debt securities and subordinated debt securities that we may offer pursuant to this prospectus. This section discusses some of those differences.

Subordination. Subordinated debt securities will be subordinate in right of payment to all senior indebtedness. "Senior indebtedness" is defined to mean, among other things, the principal, premium (if any) and unpaid interest on all present and future indebtedness of the Company for borrowed money (including indebtedness of others guaranteed by us), unless, in any case, in the instrument creating or evidencing any such indebtedness or obligation or pursuant to which the same is outstanding it is provided that such indebtedness or obligation is not senior in right of payment to the subordinated debt securities or it is expressly provided that such obligation is subordinated to other of our indebtedness and obligations.

Terms of Subordinated Debt Securities May Contain Conversion or Exchange Provisions. The applicable prospectus supplement for a particular series of subordinated debt securities will describe the specific terms discussed above that apply to the subordinated debt securities being offered thereby as well as any applicable conversion or exchange provisions.

Modification of an Indenture Relating to Subordinated Debt Securities. Each subordinated indenture may be modified by us and the trustee without the consent of the holders of the subordinated debt securities for one or more of the purposes discussed above under "-Modification and Waiver." We and the trustee may also modify each subordinated indenture to make provision with respect to any conversion or exchange rights for a given issue of subordinated debt securities.

"Street Name" and Other Indirect Holders

Investors who hold securities in accounts at banks or brokers generally will not be recognized by us as legal holders of debt securities. This is called holding in "Street Name." Instead, we would recognize only the bank or broker, or the financial institution that the bank or broker uses to hold its securities. These intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the debt securities, either because they agree to do so in their customer agreements or because they are legally required to. If you hold debt securities in "Street Name," you should check with your own institution to find out:

Direct Holders

Our obligations, as well as the obligations of each trustee under the indentures and those of any third parties employed by us or the trustee under each of the indentures, run or will run, as the case may be, only to persons who are registered as holders of debt securities issued under the applicable indenture. As noted above, we and the trustee do not have obligations to you if you hold in "Street Name" or other indirect means, either because you choose to hold debt securities in that manner or because the debt securities are issued in the form of global securities, as described below. For example, once we make payment to the registered holder, we and the trustee have no further responsibility for the payment, even if that holder is legally required to pass the payment along to you as a "Street Name" customer but does not do so.

Global Securities

What is a Global Security? A global security is a special type of indirectly held debt security as described above under "-'Street Name' and Other Indirect Holders." If we choose to issue debt securities in the form of global securities, the ultimate beneficial owners can only hold the debt securities in "Street Name." We would do this by requiring that the global security be registered in the name of a financial institution we select and by requiring that the debt securities included in the global security not be transferred to the name of any other direct holder unless the special circumstances described below occur. The financial institution that acts as the sole direct holder of the global security is called the "depositary." Any person wishing to own a debt security issued in the form of a global security must do so indirectly by virtue of an account with a broker, bank or other financial institution that in turn has an account with the depositary. The applicable prospectus supplement will indicate whether a series of debt securities will be issued only in the form of global securities and, if so, will describe the specific terms of the arrangement with the depositary.

Special Investor Considerations for Global Securities. As an indirect holder, an investor's rights relating to a global security will be governed by the account rules of the investor's financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize this type of investor as a holder of debt securities and instead deal only with the depositary that holds the global security.

An investor should be aware that if a series of debt securities is issued only in the form of global securities:

Neither we nor the applicable trustee have or will have any responsibility for any aspect of the depositary's actions or for its records of ownership interests in the global security. Also, neither we nor the applicable trustee do or will supervise the depositary in any way.

Special Situations When the Global Security Will be Terminated. In limited special situations, a global security will terminate, and interests in it will be exchanged for physical certificates representing debt securities. After that exchange, the choice of whether to hold debt securities directly or in "Street Name" will be up to the

investor. Investors must consult their own bank or brokers to find out how to have their interests in debt securities transferred to their own name so that they will be direct holders. The rights of "Street Name" investors and direct holders in debt securities have been previously described in subsections entitled "-'Street Name' and Other Indirect Holders" and "-Direct Holders."

The special situations for termination of a global security are:

The applicable prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of debt securities covered by the prospectus supplement. When a global security terminates, only the depositary is responsible for deciding the names of the institutions that will be the initial direct holders.

Form, Exchange, Registration and Transfer

Unless we inform you otherwise in an applicable prospectus supplement, we will issue the debt securities offered pursuant to this prospectus in registered form, without interest coupons, and only in denominations of $2,000 and integral multiples of $1,000 in excess thereof. We will not charge a service charge for any registration of transfer or exchange of the debt securities offered pursuant to this prospectus. We may, however, require the payment of any tax or other governmental charge payable for that registration.

Debt securities of any series will be exchangeable for other debt securities of the same series, in the same total principal amount and the same terms but in different authorized denominations in accordance with the terms of the applicable indenture. Holders may present debt securities for registration of transfer at the office of the security registrar or any transfer agent we designate. The security registrar or transfer agent will effect the transfer or exchange when it is satisfied with the documents of title and identity of the person making the request.

We will appoint the trustee under the applicable indenture as security registrar for the debt securities issued under that indenture. If a prospectus supplement refers to any transfer agents initially designated by us, we may at any time rescind that designation or approve a change in the location through which any transfer agent acts. We will be required to maintain an office or agency for transfers and exchanges in each place of payment with respect to debt securities we may offer under any of the indentures. We may at any time designate additional transfer agents for any series of debt securities.

In the case of any redemption of debt securities offered under this prospectus, neither the security registrar nor the transfer agent will be required to register the transfer or exchange of any debt security during a period beginning 15 days prior to the mailing of the relevant notice of redemption and ending on the close of business on the day of mailing of the notice, except the unredeemed portion of any debt security being redeemed in part.

Payment and Paying Agents

Unless we inform you otherwise in the applicable prospectus supplement:

Subject to the requirements of any applicable abandoned property laws, the trustee and paying agent will pay to us upon written request any money held by them for payments on the debt securities under the applicable indenture that remain unclaimed for two years after the date when the payment was due. After payment to us, holders entitled to the money must look to us for payment unless an applicable abandoned property law designates otherwise. In that case, all liability of the trustee or paying agent with respect to that money will cease.

DESCRIPTION OF CAPITAL SECURITIES

Common Stock

We may issue, either separately or together with other securities, including as a part of units, shares of our common stock. Shares of common stock issued as part of units may be attached to or separate from any other securities part of those units.

PART II

 

INFORMATION NOT REQUIRED IN PROSPECTUS

The expenses in connection with the issuance and distribution of the securities being registered, other than underwriting compensation, are:

1. Section 145 of the Delaware General Corporation Law ("DGCL"). Section 145 of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation and with respect to any criminal action or proceeding, had no reasonable cause to believe the person's conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal action or proceeding, had reasonable cause to believe that the person's conduct was unlawful.

Section 145 also provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit, if the person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability, but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

To the extent that a former or present director or officer of the corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to above, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection therewith.

Any such indemnification (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that the indemnification of the present or former director, officer, employee or agent is proper in the circumstances because such person has met the applicable standard of conduct set forth above. Such determination shall be made:

Section 145 permits a Delaware business corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against such person and incurred by such person in any such capacity or arising out of such person's status as such, whether or not the corporation would have the power to indemnify such person against such liability.

2. Section 102(b)(7) of the DGCL. Section 102(b)(7) of the DGCL provides that a corporation may set forth in its Certificate of Incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL regarding the unlawful payment of dividends or approval of unlawful stock repurchases or redemptions, or (iv) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective (in the case of Wabtec, October 19, 1989). As noted in paragraph 3 below, Wabtec's Restated Certificate of Incorporation, as amended (the "Restated Certificate of Incorporation"), includes a provision contemplated by Section 102(b)(7) of the DGCL.

3. Restated Certificate of Incorporation Provision on Liability of Directors. The Restated Certificate of Incorporation provides that no Wabtec director shall be personally liable to Wabtec or any of its stockholders for monetary damages for breach of a fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to Wabtec or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL, or (iv) for any transactions from which a director derived an improper personal benefit.

4. Indemnification By-Law. Section 1 of Article VIII of Wabtec's Amended and Restated By-Laws (the "By-Laws") provides that Wabtec shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of Wabtec) by reason of the fact that he is or was a director or officer of Wabtec, or is or was a director or officer of the Wabtec enterprise, against expenses (including attorneys' fees), payments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of Wabtec, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by payment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of Wabtec, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

Section 2 of Article VIII of the By-Laws provides that Wabtec shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of Wabtec to procure a judgment in its favor by reason of the fact that he is or was a director or officer of Wabtec, or is or was a director or officer of Wabtec serving at the request of Wabtec as a director or officer of another corporation,

partnership, joint venture, trust, employee benefit plan or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of Wabtec; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to Wabtec unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 3 of Article VIII of the By-Laws provides that any indemnification under Article VIII (unless ordered by a court) shall be made by Wabtec only as authorized in the specific case upon a determination that indemnification of the director or officer is proper in the circumstances because he has met the applicable standard of conduct set forth in Section 1 or Section 2 of Article VIII, as the case may be. Such determination shall be made (i) by a majority of the vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (ii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iii) by the stockholders. To the extent, however, that a director or officer of Wabtec has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith, without the necessity of authorization in the specific case.

Section 8 of Article VIII of the By-Laws provides that Wabtec may purchase or maintain insurance on behalf of any person who is or was a director or officer of Wabtec, or is or was a director or officer of Wabtec serving at the request of Wabtec as a director or officer of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not Wabtec would have the right or obligation to indemnify him against such liability.

5. Director and Officer Liability Insurance. Wabtec maintains director and officer liability insurance covering its directors and officers with respect to certain liabilities which they may incur in connection with their serving as such.

6. Similar Limitation of Liability. The law of the state of incorporation and/or the provisions of the certificates of incorporation, the bylaws, the limited liability company agreements or the general partnership agreements, as applicable, of all of the subsidiaries listed in the "Table of Additional Registrants" included in this Registration Statement, provide for the limitation of liability and indemnification of officers, directors, managers and persons performing similar functions, as applicable, of the subsidiaries similar to those described above.

The following exhibits are filed as part of this Registration Statement:
