Weekend Service Changes

When infrastructure repairs or upgrades require more than a few hours, we aren’t able to do them overnight, so work is scheduled over the weekend. On these weekends, buses will replace train service on the part of the line we’re working on.

Planned weekend work is listed below and will be updated if anything changes.

December 15 – 16, 2018

Buses will replace trains between Kenmore and Brookline Hills so crews can install new tracks and signals. New tracks and signals will improve the speed and reliability of Green Line service.


This is the final weekend of work on the Green Line D Branch in 2018, however, work will resume the first weekend of January between Brookline Hills and Reservoir.
