  • Contract awarded: June 2018
  • Projected completion: Fall 2021
  • Budget: $101,600,453
  • Status: 97% 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 Brookline High School Expansion Project and other D Branch work.

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.
