Updated on July 12, 2019

Between 2018 and 2020, we will replace 25,000 feet of track and 6.5 miles of signals on the Green Line, between Beaconsfield and Riverside on the D Branch.

To do this work, we need to shut down service on weeknights and on some weekends. Shuttles will replace train service, in coordination with the teams doing flood control work at Fenway, track repairs between Fenway and Riverside, and accessibility upgrades at Newton Highlands.
