South Coast Rail

Status: Early Action work for phase 1 in progress, including building demolition and culvert and bridge replacement.

See the South Coast Rail Construction Activity update

As part of our $8 billion, 5-year capital investment program, the South Coast Rail project will offer a reliable transit connection between southeastern Massachusetts and Boston. Riders will be able to take a 1-seat trip—no transfers needed—for the first time since the late 1950s.

Taunton, New Bedford, and Fall River are the only major cities within 50 miles of Boston that do not currently have Commuter Rail access to Boston. Phase 1 will bring service to these communities by late 2023.

The project will be rolled out in phases:

  • Phase 1: Extend a secondary line west from the existing Middleborough/Lakeville Line, and create the New Bedford and Fall River lines
  • Full Build: Extend the Stoughton Line south to connect more communities to the New Bedford and Fall River lines

  • We will extend Commuter Rail service on the Middleborough Secondary Line to provide a 1-seat ride to New Bedford, Fall River, and Taunton.

Phase 1 broke ground in July 2019. Construction is divided into 2 contracts, with Early Action work preceding both:

  • Construction of the Fall River Secondary Line, which will connect Fall River to Boston
  • Construction of the New Bedford Main Line, the Middleborough Secondary Line, and the signal system for the entire Phase 1 corridor, which will connect Taunton, New Bedford, and Fall River to Boston

Demolition work is being done at 9 sites as part of a separate contract to prepare for this work.

Phase 1 is expected to be completed in late 2023.

Full Build

In 2021, the design team will begin conceptual design work and preliminary engineering to seek permits and funding.

We plan to extend Commuter Rail service to travel on the Stoughton Main Line and Northeast Corridor (north of Canton Junction), connecting more communities in the region.
