details

In 2022, we’re accelerating track work on all four Green Line branches. From June through October, we’ll complete over 10,000 feet of track upgrades on the B, C, D, and E branches alongside work on the Green Line Train Protection System (GLTPS). Doing this work simultaneously will reduce the need for future Green Line closures and allow for the accelerated completion of both GLTPS and track renewal.

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.

Why We're Doing This Work

Many of the Green Line tracks are over 30 years old and have reached the end of their service life. Replacing this track will improve safety, reliability, and provide smoother trips for riders.

Rider Benefits

  • Safety: New tracks, ties, and ballast will reduce the risk of high-impact events such as derailments
  • Reliability: Fewer unplanned stops result in improved service

Work Schedule and Locations

Four full access closures are scheduled in 2022 to accelerate the installation of train protection equipment and track replacement. Before each closure, additional prep work will take place on the work sites.

What to Expect if You Live in the Neighborhood

Traffic, parking, and pedestrian impacts

During prep work and construction on each branch, lane closures will be required near work zones on the following streets to accommodate construction equipment and materials:

  • B Branch: Linden St and Commonwealth Ave
  • C Branch: Beacon St and Carlton St
  • E Branch: Huntington Ave, Longwood Ave, Forsyth Way, and South Huntington Ave around the Heath St loop

Noise impacts

The Green Line track work includes replacing rail and repaving intersections. The loudest work will occur when crews cut rails with a saw and tamp the track to the proper elevation.

This project is one of many we're working on to ensure twice as many passengers have access to a safer, more comfortable, and more reliable Green Line by 2030.
