The Red Line has more than 44 miles of track: It runs 11.5 miles from Alewife to Ashmont and 17.5 miles from Alewife to Braintree (and back!). The tracks are just a piece of the complex system that supports trains weighing hundreds of thousands of pounds—and 227,000 rider trips each weekday.

We’re working hard to keep the tracks in good repair and support new Red Line vehicles coming into service with:

  • Track replacement and station improvements through 2019
  • Floating slab maintenance in 2020

Track Replacement and Station Improvements

From November 15 – December 15, 2019, shuttles will replace train service between Kendall/MIT and Broadway on 4 weekends to support Red Line work through the T’s Capital Acceleration Plan.

These closures will allow us to complete station improvements and track replacements at Park Street 4 months earlier than planned, and at Downtown Crossing 11 months earlier than planned. We will close a broader section of the track so crews can bring vehicles and equipment into the central subway tunnel.

We thank you for your patience during these closures.
