Class III railroads (the short line and regional carriers connecting shippers to the national freight network) present a complex regulatory challenge for secured lenders. Despite their smaller scale, these operators are subject to pervasive federal regulation by the Surface Transportation Board (“STB”) that directly constrains a lender’s ability to perfect collateral, enforce remedies, and exercise control upon default. This DE Insight addresses three areas that institutional and direct lenders must master before closing a railroad credit facility: (1) STB change-of-control requirements and the exemption processes available to Class III carriers; (2) enforcement structuring through independent voting trusts and sequenced remedies; and (3) the federal rolling stock perfection regime under 49 U.S.C. § 11301 and 49 C.F.R. Part 1177.
STB Control and Operating Authority
Under 49 U.S.C. § 11323, any transaction that constitutes an acquisition of control over a rail carrier (including indirect control through holding companies, management agreements, or the exercise of pledged voting rights) requires either STB approval or a valid exemption before it can take effect. Unlike traditional corporate control tests that typically require majority voting power or board control, the STB applies a functional, facts-and-circumstances analysis. “Control” means the ability to direct or influence the management or policies of the carrier and can be found at ownership levels well below majority thresholds, through contractual arrangements that confer operating influence, or via interlocking governance or financial leverage. Lenders therefore cannot assume that foreclosing on pledged equity, replacing management, exercising voting rights, or directing operations is purely private-contract enforcement. Each of those actions can itself constitute STB-regulated control, triggering enforcement authority and potential unwinding of the transaction.
For Class III carriers, two principal exemption pathways exist: the Class III acquisition and operation exemption under 49 C.F.R. § 1150.42, and the continuance-in-control exemption under 49 C.F.R. § 1180.2(d)(2). The acquisition and operation exemption is straightforward. It becomes effective 30 days after filing a verified notice and caption summary with the STB. The continuance-in-control exemption applies where the acquired carrier’s lines do not connect with the existing rail network of the acquiror or any entity in its corporate group, no Class I carrier (major interstate freight railroads with annual operating revenues exceeding the STB threshold, currently approximately $1 billion) is involved, and the transaction is not part of a series of anticipated connecting transactions. Under both pathways, the transaction generally becomes effective 30 days after the verified notice is filed. Lenders should be prepared to file all verified notices, supporting documentation, and counsel signoffs simultaneously with the exercise of remedies upon default.
Understanding the control and exemption framework is essential, but equally important is how lenders structure their enforcement rights to work within these regulatory constraints.
Enforcement Structuring: Voting Trusts and Sequenced Remedies
Given the STB’s broad view of what constitutes control, lenders must carefully distinguish between remedies that can be exercised immediately upon default and those that require regulatory clearance.
A lender-facing enforcement structure should bifurcate immediate economic remedies from deferred control remedies. Immediate economic remedies (such as acceleration, default-rate interest, cash dominion, blocking distributions, and account redirection) do not transfer or vest control over the carrier’s operations and should be authorized to proceed automatically upon an event of default without regulatory precondition. The typical control remedies that lenders are accustomed to, however, must be carefully sequenced through STB-compliant mechanisms.
One mechanism for managing the gap between default and regulatory approval is the voting trust. In Class I transactions, voting trust agreements under 49 C.F.R. Part 1013 are commonly used to hold acquired equity during lengthy STB review periods. That approach is less practical for Class III financings, where the deal timeline and economics do not support a standing trust structure that sits idle until a default occurs. A more tailored solution is the springing voting trust, a structure pre-negotiated at closing that activates only upon an event of default and delivery of an activation notice by the collateral agent. Upon activation, all voting and consensual rights over the carrier’s equity vest exclusively in an independent trustee, while the collateral agent retains only the beneficial interest and economic rights. The trustee must satisfy the strict independence requirements applicable to voting trusts, including no officers, directors, or employees in common with, and no business affiliation with, the lender, the borrower, or their respective affiliates. Although the trustee holds and votes the equity in its own independent discretion, neither the lender nor the collateral agent may consult with, influence, or direct the trustee on railroad operations, budgets, rates, service levels, management appointments, capital expenditure plans, interchange, dispatching, or any other matter that could constitute control. Day-to-day railroad operations remain with existing management pending STB authorization for a permanent control transfer. Promptly following activation, a verified notice under 49 C.F.R. § 1013.3(b) should be filed.
The springing voting trust in a financing transaction presents what the STB has characterized as “novel circumstances” not addressed in existing STB precedent. While the STB has indicated it cannot provide informal guidance in the absence of applicable precedent, the lack of precedent should not render the structure impermissible or ineffective.
Beyond the voting trust, lenders should build several additional protections into the loan documentation. First, consider pre-negotiating for the appointment of a court-appointed receiver with rail industry experience and carefully limited authority. Second, condition any remedies affecting railroad assets on first obtaining the required STB approval, exemption, or authorization. Third, require that any purchaser in a disposition have the necessary regulatory authority and STB approval in place before the transfer closes. Finally, include robust cooperation covenants requiring the borrower and its principals to assist with STB applications, exemption petitions, and verified notices.
With enforcement structures in place, lenders must also address a distinct but equally critical issue: how to properly perfect their security interests in railroad equipment.
Rolling Stock Perfection and Collateral Considerations
Lenders accustomed to UCC Article 9 filings face a different regime when it comes to railroad rolling stock. Federal law governs perfection, and a misstep here can leave a lender with an unperfected security interest.
Under 49 U.S.C. § 11301 and 49 C.F.R. Part 1177, security interests in railroad rolling stock (which are broadly defined to include locomotives, freight cars, maintenance-of-way equipment, work equipment, parts, replacements, and associated records) are perfected by recordation with the STB, not by filing with a secretary of state under UCC Article 9. This federal regime preempts the UCC, and a security interest in rolling stock perfected only by a UCC filing is unperfected as a matter of federal law. Lenders should require, as a condition to closing, a special STB counsel opinion confirming: (i) proper recordation under § 11301 and Part 1177, (ii) perfection and priority of the rolling stock security interests, (iii) that the lien grant and perfection themselves do not require STB approval (as distinct from the control-related approvals discussed above), and (iv) compliance with the change-of-control and voting trust requirements under 49 U.S.C. § 11323 and 49 C.F.R. Part 1013.
From a documentation standpoint, collateral schedules for rolling stock should identify each item by description, identification number, reporting mark, and title evidence. Loan documents should require periodic reporting, typically monthly, tracking inventory, equipment identifiers, condition, title changes, lease changes, STB recordation status, and liens. Keep in mind that equipment falling outside the federal definition of railroad rolling stock may still be subject to UCC Article 9, so parallel filings are necessary to achieve full perfection across all equipment types. Before closing, lien searches must cover both STB recordation records and UCC indices to identify existing encumbrances. Lenders should also require evidence of a current STB Memorandum of Recordation or Statement of Recordation. These are the official STB-issued documents confirming that the security interest has been properly recorded and establishing the lender’s priority position in the collateral.
Getting these collateral mechanics right at the outset is essential to ensuring that a lender’s security interest will hold up in an enforcement scenario.
Conclusion
Class III railroads present attractive lending opportunities, but the STB regulatory framework requires lenders to structure their documentation and enforcement strategies carefully. Several core principles are critical. First, lenders should conduct thorough diligence on all operating authorities, ownership structures, and exemption histories before closing. Second, upon a default, lenders should be prepared to file all required verified notices and supporting documentation concurrently with the exercise of remedies. Third, lenders should consider implementing an innovative springing voting trust arrangement that becomes effective (i.e., activated) upon default, providing oversight and preserving value while any STB approvals necessary to exercise control-related remedies are pending. Fourth, security interests in rolling stock should be perfected through STB recordation under Part 1177, supplemented by UCC filings where appropriate. Finally, enforcement actions should be sequenced to distinguish between economic remedies that may be exercised immediately and control-related remedies that remain subject to STB review and approval.
Lenders that incorporate these considerations into their financing documentation will be well positioned to protect their interests and exercise remedies efficiently while remaining compliant with federal regulatory requirements.
