MBTA extends Green Line track, signal work

The Massachusetts Bay Transportation Authority (MBTA) last week began track and signal work on the Green Line between the Newton Highlands Station in Newton, Massachusetts, and Kenmore Station in Boston. 

During construction, which is expected to be completed by Dec. 20, crews will replace track, ties and ballast; build new signal equipment; replace cables; and repair catenary poles, MBTA officials said in a press release. 

The work is part of the Green Line’s D-branch track and signal replacement project, which involves replacing 6.5 miles of signal infrastructure and 25,000 feet of track. It also includes special trackwork between Beaconsfield Station in Brookline and Riverside Station in Newton. 

Crews also will centralize signal equipment at D branch stations, replace signal equipment with modern technology and replace jointed rail with continuous-welded rail. 

Shuttle buses will replace Green Line service between the stations during the construction.
