Ashmont Branch and Mattapan Line Track Upgrades

We’re making major track improvements across the Red Line’s Ashmont Branch and Mattapan Line.
In order to complete this work, shuttle buses will replace service on the Ashmont Branch and Mattapan Line from Saturday, October 14 – Sunday, October 29.
During this time, crews will replace ties and complete full-depth track replacement at several locations along the lines. Replacing this track will help address speed restrictions and bring a smoother ride for passengers.
Rider Benefits
- Safety: New rails, ties, and ballast reduce the risk of unplanned service disruptions
- Reliability: Increase speed for a more consistent schedule
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 if You Live in the Neighborhood
The Red Line trackwork includes full-depth track replacement and upgrading one grade crossing. The loudest work will occur when crews cut rails 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 will monitor noise levels and respond to all noise complaints received on the MBTA Improvement Work Hotline that is available to the public 24/7. To report a construction-related noise issue, call the system-wide project hotline at 617-222-4100.
