In 2022, we’re accelerating track work on all four Green Line branches. From June through October, we’ll complete over 10,000 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 will reduce the need for future Green Line closures and allow for the accelerated completion of both GLTPS and track renewal.
Building a Better T
As part of our $8 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're Doing This Work
Many of the Green Line tracks are over 30 years old and have reached the end of their service life. Replacing this track will improve safety, reliability, and provide smoother trips for riders.
Rider Benefits
- Safety: New tracks, ties, and ballast will reduce 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 are scheduled in 2022 to accelerate the installation of train protection equipment and track replacement. Before each closure, additional prep work will take place on the work sites.
Service Changes
Bus shuttles will replace train service. Shuttles will not stop at Warren St, Allston St, or Packard's Corner stations. Riders should use nearby Washington St, Harvard Ave, and Babcock St stations 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 will be 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
- E Branch: Huntington Ave, Longwood Ave, Forsyth Way, and South Huntington Ave around the Heath St loop
Parking lanes will be shifted for local traffic and emergency vehicles as necessary. Some parking will be temporarily removed to allow for the storage of materials and equipment, emergency access, and/or traffic detours.
Existing bike lanes will be maintained. Crosswalks in work zones may be closed. Alternative pedestrian crossings will be marked with detour signage.
Detour signage will be in place for vehicles and pedestrians, and police officers will be located at key locations to ensure safety.
Prep work activities leading up to the full access closure will take place from Monday, June 6 – Friday, June 10, and will not require a service diversion.
During the prep work the following traffic, parking, and pedestrian impacts are planned along the B Branch:
- Packard’s Corner to St. Lukes Road – Welding will take place in the parking spaces on Commonwealth Avenue outbound collector road between Brighton Avenue and St. Lukes Road. Work will be performed during revenue daytime hours between 7 AM and 3 PM within the temporary collector road lane closure. Temporary lane closures and detours will be set up prior to starting welding.
- Traffic heading Eastbound down Brighton Avenue looking to travel between Brighton Avenue and St. Lukes on the collector road will be directed to take a right down St. Lukes Road.
- Workers will store the rail strings against the curb closest to the Green Line tracks and block them off with traffic drums with caution tape running the entire length of the rail strings.
Noise impacts
The Green Line track work includes replacing rail and repaving intersections. The loudest work will occur when crews cut rails with a saw and tamp the track to the proper elevation.
We use several strategies to minimize noise disruptions to neighbors:
- Assembling track panels off-site
- Accessing work sites through the MBTA right-of-way
- Using self-adjusting backup alarms, silencers, or mufflers on equipment
- Limiting truck and equipment idling
- Lining dumping bins, hoppers, and trucks with sound-deadening material
- Using noise blankets and shielding where possible
We monitor noise levels and respond to all noise complaints. If you would like to report a noise issue, please call the 24/7 hotline at 617-222-4100.
