Green Line B Service Changes

Throughout 2020, we’ll be performing maintenance and planned work on the Green Line to bring you better, safer, and more reliable subway service. Some of this work is part of Building a Better T 2020—which accelerates previously planned work so we can deliver results to riders sooner.

no service Shuttles will not stop at Allston St, Griggs St, and Packards Corner due to accessibility barriers.

This service change supports Green Line track and intersection upgrades.

accessible Accessibility

Shuttles are accessible to people with disabilities. Some bus shuttles may be provided by third-party contractors and will look different than MBTA buses. Some may provide accessibility via a lift in the back rather than a ramp in front.

Babcock Street will be equipped with mobile lifts to enable accessible boarding and exiting of trains.

Trains Run at Reduced Speed

After completing track work, we typically implement speed restrictions while we monitor the tracks to ensure that ballast and other materials have settled properly. Restrictions are lifted after we get confirmation from an engineer, which can sometimes take several days.
