South Coast Rail

Locomotive on the tracks at South Coast Rail groundbreaking in Freetown

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—from Fall River and New Bedford into Boston.

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. This work will get service to these communities as soon as possible.

The project will be rolled out in phases:

  • Phase 1: Extend the Middleborough/Lakeville Line west, 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
