About the Project

Timeline: 2015 – 2022

As the MBTA prepares for the arrival of our new and expanded Red Line fleet, we’re making infrastructure investments to support storage, testing, and maintenance of the new vehicles. These investments are part of the Red Line/Orange Line Improvements Program. 

This work is being done alongside the signal systems upgrade project, also part of the program.

Red Line improvements include:

  • Cabot Yard and maintenance facility improvements
  • Installation of test track

Cabot Yard and Maintenance Facility Improvements

Cabot Yard, where all of the Red Line’s vehicles are stored and cared for each day, will get major infrastructure upgrades to accommodate the new fleet. 

Installation of Test Track

Alongside work at Cabot Yard, a new test track is being built to test and commission new Red Line vehicles.
