Massachusetts has released proposed rail safety standards under the Department of Public Utilities (DPU) oversight, opening a rulemaking that will reach commuter, freight and tourist rail operators across the Commonwealth. The move sets up a multi-month process of public comment, hearings and revisions before any final adoption.

The proposed standards will govern rail carriers operating on state-jurisdiction track in Massachusetts, excluding the Northeast Corridor mainline, which the Federal Railroad Administration regulates directly. Operators in scope include the MBTA commuter rail system — the nation's fifth-busiest commuter rail network — together with Class I freight railroads CSX and CPKC, the merged entity that absorbed the former Pan Am Railways in 2023, and several short-line operators.

What state rail safety rules typically cover

State-level rail safety standards in Massachusetts have historically addressed track inspection frequency, operating practices, employee qualifications, hazardous-materials handling, and grade-crossing protocols. The DPU's rail safety division enforces federal standards where applicable and supplements them with state-specific requirements, particularly on lines outside Northeast Corridor jurisdiction. Recent federal action on Positive Train Control, two-person crew rules and hazmat routing is expected to feature in the new state-level framework.

The MBTA commuter rail network runs under a contract with Keolis Commuter Services, a subsidiary of France-based Keolis Group. Keolis has operated the network since 2014 under a multi-year contract with the MBTA, currently the largest commuter rail operating contract in North America by ridership. The MBTA itself oversees service planning, fare policy and capital investment, while day-to-day operations fall to Keolis.

Who else is in scope

Short-line freight operators with track in Massachusetts include the Housatonic Railroad, the Grafton and Upton Railroad, and the Massachusetts Central Railroad, among others. Tourist and heritage railways on state-jurisdiction track — including the Cape Cod Central Railroad and seasonal excursion services — also fall within the state framework.

The MBTA owns about 394 route-miles of commuter rail, and the broader Massachusetts rail network includes additional freight-only segments and shared-use corridors operated by the Class I railroads and short-line partners. Together, these lines handle a mix of containerized freight, automotive traffic, and bulk commodities including propane and lumber that move between Massachusetts ports and inland destinations.

Why the rulemaking matters

State-level rail safety rulemaking has gained attention across the Northeast following high-profile derailments and grade-crossing incidents in recent years. Massachusetts last updated its state-level rail safety framework several years ago, and operators have anticipated further revisions as federal regulators have moved on Positive Train Control implementation, two-person crew rules, and other safety mandates.

The DPU's proposed standards will likely draw comments from the MBTA, Keolis, Class I railroads, labor organizations including the SMART Transportation Division, and the American Short Line and Regional Railroad Association. Compliance costs, training requirements, and inspection protocols are typical friction points during state-level rail safety rulemaking, particularly for smaller short-line operators with limited regulatory affairs capacity.

State-level track-class adjustments could affect allowable freight car weights and operating speeds across the network. Any changes to hazmat-handling protocols will also intersect with Class I routing decisions for unit trains of crude oil, ethanol, and propane that pass through the state.

What comes next

The DPU is expected to publish the full proposed text in the coming days, with a public comment window and likely public hearings to follow. Final adoption would set the regulatory baseline for Massachusetts-jurisdiction rail operations through the next several years, ahead of any subsequent federal-level changes under the next FRA rulemaking cycle. Operators will need to align training, documentation, and inspection schedules once a final rule is in hand.
