Green Line Track Upgrades (2022)
In 2022, we accelerated track work on all four Green Line branches. From June through October, we completed over 14,000 feet of track upgrades on the B, C, D, and E branches alongside work on the Green Line Train Protection System (GLTPS). Doing this work simultaneously reduced the need for future Green Line closures and allowed for the accelerated completion of both GLTPS and track renewal.
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
Many of the Green Line tracks were over 30 years old and had reached the end of their service life. Replacing this track improved safety and reliability, and provided smoother trips for riders.
Rider Benefits
- Safety: New tracks, ties, and ballast reduces the risk of high-impact events such as derailments
- Reliability: Fewer unplanned stops result in improved service
Work Schedule and Locations
Four full access closures were scheduled in 2022 to accelerate the installation of train protection equipment and track replacement. Before each closure, additional prep work took place on the work sites.
Service Changes
Bus shuttles replaced train service. Shuttles did not stop at Warren St, Allston St, or Packard's Corner stations. Riders could use nearby Washington St, Harvard Ave, and Babcock St stations as alternatives.

What We Accomplished

- Linden St intersection and Fordham Rd pedestrian crossing
- Special trackwork at the intersection of Commonwealth Ave and Washington St
- Special trackwork on Commonwealth Ave between Lake St and Greycliff Rd
Service Changes
Bus shuttles replaced train service. Shuttles did not stop at Brandon Hall or Kent St stations. Riders could use either Fairbanks St or Summit Ave instead of Brandon Hall, and either St. Paul St or Hawes St instead of Kent St.

What We Accomplished
- Track replacement in the tunnel from St Mary's St portal to Beacon Junction (near Kenmore)
Service Changes
Buses replaced train service. Route 39 bus service was enhanced with additional accessible buses between Heath St and Copley Station. Shuttle stops along Huntington and South Huntington avenues were located at the existing bus stops for Bus Route 39. This additional bus service schedule met or exceeded the frequency of the current Green Line E Branch schedule.

- Track replacement at the Heath Street loop
Service Changes
Bus shuttles replaced train service. Shuttles did not stop at Beaconsfield station. Riders could use the C Branch from Dean Road or access the shuttle from Reservoir station as alternatives.

What to Expect if You Live in the Neighborhood
Traffic, parking, and pedestrian impacts
During prep work and construction on each branch, lane closures were required near work zones on the following streets to accommodate construction equipment and materials:
- B Branch: Linden St and Commonwealth Ave
- C Branch: Beacon St and Carlton St
- D Branch: Riverside Yard
- E Branch: Huntington Ave, Longwood Ave, Forsyth Way, and South Huntington Ave around the Heath St loop
Noise impacts
The Green Line track work included replacing rail and repaving intersections. The loudest work occurred when crews cut rails with a saw and tamped the track to the proper elevation.
