More shutdowns are coming to the MBTA in the first half of 2025 as the T builds on the success of last year’s slow zone elimination campaign.

The T released its schedule of planned construction through June, forecasting periodic weekend outages for parts of the commuter rail and shutdowns longer than a week on the Red, Orange, and Blue lines. In an accompanying news release, the agency said it’s shifting its focus from slow zones to “upgrading other critical infrastructure, including signal systems, improving accessibility across the network, and more.”

More on the MBTA:

Signal upgrades on the Red and Orange lines in particular will help the T reduce congestion and delays while allowing for more frequent service and shorter wait times, according to the release. Other key initiatives for 2025 include staying on top of annual maintenance, rolling out the Green Line Train Protection System anti-collision technology, and completing bridge work along various commuter rail lines, the T said.

“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,” MBTA General Manager Phil Eng said in a statement.

He added: “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, building out a best-in-class system for the Commonwealth.”

Most of that work will come during weekends and evenings, minimizing the disruption to weekday commuters, the MBTA said. However, some lines are due for longer outages.
