Red Line Signal Testing Begins Between Harvard and Alewife
Updated on September 27, 2021
As part of the Red Line Transformation Program, we’re replacing the analog signal system with new digital infrastructure.
This project will improve service reliability, renew the system’s lifespan, and provide more efficient system diagnostics on the Red Line.
Building a Better T
As part of our $9.6 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.
What to Expect During This Work
Crews will test the new signaling system over several weekends as we prepare to transition to upgraded signaling technology on this segment of the Red Line.
Service Impacts
Shuttles replace trains between Alewife and Harvard on the following weekends:
- September 25 – 26
- October 30 – 31
- November 13 – 14
