As part of the Green Line Transformation (GLT), we replaced 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
  • Project completed: December 2021
  • Budget: $101,600,453
  • Status: 100% 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 needed to shut down service on most weeknights and weekends. We coordinated D Branch shuttle service with Fenway Park, the Brookline High School Expansion Project, and other D Branch work.

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.

What to Expect if You Live in the Neighborhood

The track work at these locations included replacing rail, railroad ties, and stone ballast. The noisiest work occurred when crews cut the rails with a saw or torch and tamped the track to the proper elevation.
