South Coast Rail is a public transportation project undertaken by the Massachusetts Bay Transportation Authority (MBTA) to extend commuter rail service from Boston to the cities of Fall River and New Bedford on the southern coast of Massachusetts. The project aims to provide a faster, more reliable rail connection for residents of southeastern Massachusetts, reducing travel times to Boston and expanding regional transit options.
Background and Planning
- The concept of extending commuter rail service to the South Coast region dates to the early 2000s, with feasibility studies identifying potential benefits for economic development and traffic reduction.
- Formal planning for the South Coast Rail project began in 2009, when the MBTA and the Commonwealth of Massachusetts released a Joint Committee on the South Coast Rail Study. The study evaluated alternative routes, cost estimates, and projected ridership.
Project Scope
- The project involves upgrading existing freight rail lines owned by the Massachusetts Department of Transportation (MassDOT) and the Providence and Worcester Railroad, as well as constructing new track segments, stations, and related infrastructure.
- Two primary service branches are planned: a Fall River branch terminating at Fall River Station and a New Bedford branch terminating at New Bedford Station. Both branches will converge at a shared segment before reaching the existing MBTA commuter rail network at Middleborough.
Funding and Timeline
- Funding for South Coast Rail has been secured through a combination of state appropriations, federal grants, and the MBTA’s capital budget. Significant allocations were made in the 2010 and 2012 state budgets, supplemented by a $1.1 billion federal grant awarded in 2017.
- The project is divided into two phases: Phase 1, the “Interim” service to New Bedford via the Middleborough/Lakeville Line, and Phase 2, the “Full” service extending to both Fall River and New Bedford via new track construction. Phase 1 service to New Bedford commenced on July 5 2023. Phase 2 construction is ongoing, with projected completion in the late 2020s, subject to funding and environmental review outcomes.
Stations and Infrastructure
- Planned stations include:
- South Coast Rail – Fall River Station (near the former Fall River rail yard)
- South Coast Rail – New Bedford Station (near the New Bedford waterfront)
- Intermediate stations at: Dighton, Middleborough/Lakeville, Taunton, Stoughton, and Brockton (selected based on demand analyses).
- Upgrades include signal modernization, grade crossing improvements, and the addition of parking facilities and bus connections at key stations.
Operational Impact
- The extension is expected to increase MBTA commuter rail ridership by tens of thousands of trips annually.
- Travel time between Boston’s South Station and New Bedford is projected to be approximately 1 hour 30 minutes, compared with prior bus and automobile travel times of 1 hour 45 minutes to 2 hours.
Current Status
- As of 2026, Phase 1 service to New Bedford is operational, providing daily commuter rail trips. Construction on the new track segment between Middleborough and Fall River is in the final stages, with track laying and signal installation progressing under the oversight of MassDOT and the MBTA.
