Here are the MBTA service outages planned for the first half of 2025
Briefly

The Massachusetts Bay Transportation Authority (MBTA) is anticipating several shutdowns in early 2025 to enhance its infrastructure and reduce congestion. These shutdowns result from a shift in focus from slow zone eliminations to critical infrastructure upgrades, particularly signal systems, to improve rider experience. Notable initiatives include the rollout of the Green Line Train Protection System and extensive bridge work on commuter lines. This comprehensive construction plan aims to minimize disruptions by scheduling work during weekends and evenings. MBTA aims to enhance service reliability while communicating potential changes to service schedules.
In 2025, the T is committed to proactive maintenance and repairs, including completing critical signal upgrades, which will allow us to deliver the level of service our riders expect and need.
With a never-ending focus on the public we serve, we will continue to improve how we efficiently and effectively perform work to minimize disruptions and deliver meaningful results.
