A portion of the Fitchburg commuter rail line will be shut down on a half-dozen weekends this spring so work can be done on the tracks, according to the company that runs commuter rail for the MBTA.
The Massachusetts Bay Commuter Railroad Co. says that it will shut down service between the South Acton and Fitchburg stations each weekend beginning on Saturday, April 21, and continuing through Sunday, June 3.
It says the work, which is necessary to upgrade the line to a double-track system, has been scheduled for weekends to minimize customer impact.
Service between the South Acton and Fitchburg stations will be replaced by bus service. The company says in a statement that delays of 25 minutes are anticipated for customers traveling on the weekends.
The company says there is one exception: Weekend service will run as normally scheduled on Memorial Day weekend, May 26 and May 27.
