Between 2018 and 2020, we will replace 25,000 feet of track and 6.5 miles of signals on the Green Line, between Beaconsfield and Riverside on the D Branch.

Building a Better T

As part of our $8 billion, 5-year capital investment plan, we're renovating stations, modernizing fare collection systems, upgrading services for our buses, subways, and ferries, and improving the accessibility of the entire system.

  • Contract awarded: June 2018
  • Projected completion: December 2020
  • Budget: $101,600,453
  • Status: 37% construction complete

As part of the Green Line Transformation (GLT), this project meets the following goals:

  • Service delivery: Speed restrictions lifted on some sections of the Green Line for faster service
  • Safety and resiliency: New tracks and signals mitigate risk of service interruptions due to track conditions and reduce time and money needed for maintenance

To do this work, we need to shut down service on weeknights and on some weekends. Shuttles will replace train service, in coordination with the teams doing flood control work at Fenway, track repairs between Fenway and Riverside, and accessibility upgrades at Newton Highlands.
