Weekend commuter rail disruption will now leak into Fridays

"Commuter rail trains will not serve North Station on March 20-22, March 27-29, April 10-12, and April 24-27, transportation officials said in a statement Monday. Regular service will run during the Boston Marathon weekend, according to the MBTA."

"Trips between Anderson/Woburn and North Station may take up to 15 minutes longer on express shuttles and up to 40 minutes longer on local buses, the MBTA said. Travel from Swampscott could take up to 40 minutes longer on express buses and up to 70 minutes longer on local service, according to the MBTA."

"The service changes are part of an ongoing signal modernization project at Tower A, which controls all train movements in and out of North Station, transportation officials said. The project works in conjunction with a future project that will replace the drawbridge over the Charles River."

The MBTA and Keolis Commuter Services are extending planned weekend commuter rail shutdowns at North Station into several Fridays for signal modernization work. Service suspensions occur March 20-22, March 27-29, April 10-12, and April 24-27, with regular service maintained during Boston Marathon weekend. Different commuter rail lines will experience varying service replacements: the Lowell Line uses shuttle buses between North Station and Anderson/Woburn; the Newburyport/Rockport Line operates shuttles to Swampscott with Blue Line connections; the Haverhill Line uses Orange Line service; and the Fitchburg Line uses Red and Green lines. Riders should expect significant delays, with travel times increasing by 15-70 minutes depending on the line and bus type used.
