The MBTA is planning multiple service suspensions on weekdays in March on both the Red and Orange Lines for what the agency says will be “critical signal upgrade work.”

Red Line train service between JFK/UMass and Braintree stops will be replaced with shuttle buses on March 8 and 9, March 22 and 23 and March 29 and 30. Free shuttle service will be available for all suspended stops, and the Middleborough, Kington, and Greenbush Commuter Rail lines will provide fare-free service between Braintree, Quincy Center, JFK/UMass, and South Station.

The T had previously announced that train service on the Red Line’s Ashmont branch will be shut down in April for nine days (April 1-9) to conduct “proactive rail maintenance work.”

Orange Line service will be also suspended between Jackson Square and North Station this coming weekend (March 1-2). Inbound Green Line service at Copley and remaining services at Jackson Square will be fare-free, along with Commuter Rail service between Forest Hills and South Station.

Another Orange Line suspension between Oak Grove and North Station will begin at approximately 8:30 p.m. on March 7 and run through March 9. The Haverhill Commuter Rail Line will also be fare-free during this timeframe, and free shuttle service will run during all Orange Line suspensions at the necessary stops.

The Red Line suspensions are due to ongoing signal upgrade projects to “allow for more frequent service, improved scheduling, and enhanced safety” that will be fully completed in the fall of 2027, according to the T.
