Green Line D Track and Signal Replacement

A team of workers install new signal cables near Chestnut Hill on the Green Line D branch.

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.

  • Contract awarded: June 2018
  • Projected completion: Fall 2021
  • Budget: $101,600,453
  • Status: 72% 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 most weeknights and weekends. Shuttles will replace train service, in coordination with the Fenway Portal Project and the Brookline High School Expansion Project.

What You Can Expect During This Work

Work Locations

Crews are working most weeknights and weekends through the end of 2020 at various locations between Riverside and Beaconsfield. The schedule for this major infrastructure project is weather-dependent and subject to change without notice.

Other nearby projects, such as the Fenway Portal Project and the Brookline High School Expansion Project, may also occur simultaneously.

What to Expect if You Live in the Neighborhood

The track work occurring at these locations includes replacing rail, railroad ties, and stone ballast. The noisiest work will occur when crews cut the rails with a saw or torch and tamp the track to the proper elevation.
