This service change is in place while crews perform work as part of the Track Improvement Program, which will alleviate speed restrictions along the line.

Following up on the previous announcement from December 21, the MBTA is  reminding riders that Green Line service on the B branch between North Station and Babcock Street, on the E branch between North Station and Heath Street, and on the C and D branches between North Station and Kenmore station will be suspended all day from start to end of service for 10 days from January 3-12 and for 13 days from January 16- 28.

As previously announced, this service change is in place while crews perform work as part of the Track Improvement Program, which will upgrade infrastructure in order to improve reliability, alleviate safety-related speed restrictions along the line, and improve travel times for MBTA riders. This service change follows the successful and on-time completion of other recent critical track work on the Green Line D branch with service restored December 21 that removed 22 speed restrictions, which was two more than planned.

Riders should note that, in observance of the Martin Luther King Jr. Day holiday weekend, Green Line trolley service will operate during the weekend of January 13-14 and on Monday, January 15.

A page with dedicated information for riders is available at mbta.com/GreenLine. Travel alternatives during this service change are below:

Riders should note that shuttles do not stop at Blandford Street with riders instead asked to connect to services at BU East or Kenmore.
