Buses to Replace Red Line from Harvard to Alewife for Weekend Repairs


red line train

The Red Line track from Harvard to Alewife sits on concrete slabs that float on rubber disks which absorb noise and vibration from trains.  Years of water filtration into the tunnel has resulted in corrosion and cracking that must be addressed in order to maintain safe and reliable Red Line service.

Beginning November 5, MBTA work crews will be removing and replacing corroded concrete slabs as part of a project partially funded by the American Recovery and Reinvestment Act.  In addition to correcting problems with the floating slab structure, the project will involve the replacement of track and 3rd rail.  Workers will also address leaks in the tunnel to prevent further deterioration.

Weekend Bus Replacement
Due to the complexity of this project, work cannot be completed during the short overnight period when service is not operating.  Materials can only be brought to the job site by rail, and the nearest access point is more than two miles away near the Longfellow Bridge.  Also, the concrete requires a certain period of time to settle before train service can begin.

As a result, buses will replace Red Line trains every weekend between November and March , with the exception of Christmas and New Year's Day.
