MBTA Advances Signal Work on Four Commuter Lines
Four MBTA commuter rail lines to use shuttle buses for signal work on two March weekends
MBTA Commuter Rail Lines Face Service Changes
Four MBTA Commuter Rail lines will operate with shuttle buses and subway service instead of regular trains during two upcoming weekends, transit officials said. The Newburyport/Rockport, Haverhill, Lowell, and Fitchburg Lines will see service replacements to North Station on Friday through Sunday, March 20-22 and March 27-29, as crews complete signal improvement work. Weekend schedules are available now, though officials haven't released Friday timetables yet.

Signal Work Drives Service Changes
The service modifications are necessary to allow crews to perform signal improvement work that can't be completed while trains are running, according to the transit agency. Signal systems control train movements and are critical for safe operations on commuter rail networks. Officials said the work is part of ongoing infrastructure maintenance and upgrades across the system. Transit agencies typically schedule major signal work during weekends and overnight hours to minimize disruption to weekday commuters, though the scope of this particular project wasn't specified.
Shuttle Buses and Subway Replace Train Service
Riders on the four affected lines will need to use shuttle buses and existing subway connections to reach North Station during the service replacement periods. Officials said weekend schedules showing shuttle bus stops and timing are currently available, but didn't specify where riders can access those schedules. Friday service details will be released soon, though a specific date for when that information becomes available wasn't provided. The agency hasn't said how many shuttle buses will operate or what the expected travel times will be compared to regular train service.
Two Weekend Periods Affected
The service replacements will take effect Friday through Sunday on two separate weekends: March 20-22 and March 27-29. Officials didn't specify what time Friday service changes begin or when regular train service resumes Sunday evenings. The two-weekend timeline suggests the signal work requires extended access to the tracks, though officials haven't detailed the specific improvements being made or why the work is split across non-consecutive weekends.
Riders Should Plan for Longer Trips
Commuters and weekend travelers should expect longer journey times when using shuttle buses instead of direct train service to North Station. Officials recommend checking schedules before traveling, though they haven't said whether additional customer service staff will be available to assist riders navigating the temporary service changes.
