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.
Why We Did This Work
Updating the track and signals on the D Branch has several benefits:
- New digital signals can be monitored remotely, so our crews can diagnose and repair problems faster
- With new tracks, we can lift speed restrictions on some sections of the Green Line, saving two and a half minutes of travel time in each direction
- Reduces future need for service disruptions during maintenance or repairs
What We Accomplished
Between June 2018 and December 2021, crews replaced 25,000 feet of track and 6.5 miles of signals on the D Branch between Riverside and Beaconsfield stations.
During this work, service was periodically shut down for track maintenance. This included four nine-day closures that allowed crews to complete the most disruptive work quickly. Early in the project, we worked closely with Fenway Park to provide alternative service for riders while crews worked on the D Branch.
Now that the project is complete, riders can enjoy safer, more reliable service on the D Branch.
