The Green Line D Track and Signal Replacement project will replace 25,000 ft. of track and 6.5 mi. of signal infrastructure on the Green Line D branch.
The MBTA's contractor, Barletta-Fischbach, is scheduled to begin overnight work on the Green Line D Track and Signal Replacement Project. Work will take place in Brookline on Sunday through Thursday nights through Dec. 28, 2018. Work also will occur on select weekends in November/December in Brookline. Depending on progress in Brookline, overnight work could begin in Newton (between Newton Highlands and Riverside) in November/December.
The Green Line D Track and Signal Replacement project will replace 25,000 ft. of track and 6.5 mi. of signal infrastructure on the Green Line D branch. This project is an MBTA initiative to bring the Green Line track and signal systems into a state of good repair. New tracks and a signal system centralized at stations with modern electronics will help improve the reliability of Green Line operations between Beaconsfield and Riverside stations. Continuous welded rail will replace jointed rail, resulting in a smoother ride for trains. Construction is scheduled to begin in October and continue through December 2020.
Impacts to Green Line Riders
Bus shuttles will replace Green Line D branch service between Brookline Hills and Reservoir until Oct. 18 on Sundays through Thursdays, from 9 p.m. to end of service. Customers should anticipate adding 15 minutes to their normal trip during this time. From Oct. 21 to Dec. 28, bus shuttles will replace Green Line D branch service between Kenmore and Reservoir on Sundays through Thursdays, from 9 p.m. to end of service.
This extended diversion is required for both the Green Line D Track and Signal Replacement Project as well as the Fenway Portal Project that is constructing flood control measures at the entrance to the Green Line subway tunnel near Fenway station. Regular service will run on nights of Red Sox postseason home games.
Additionally, over at least 15 weekends in 2019 and 2020, shuttle buses will replace train service on portions of the D Branch all day Saturday and Sunday. Those dates will be posted on the project website and shared in emails to everyone on the mailing list.

Impacts to Residents, Businesses
The MBTA's contractor is scheduled to begin overnight work on Sundays through Thursdays (from 9 p.m. to 5 a.m.) in Brookline. The contractor will replace approximately 100 ft. of rail during each overnight shift. The noisiest work will occur after 9 p.m. when the contractor is cutting the rails with a saw or torch, then later overnight when the track is being tamped to the proper elevation. In addition to assembling track panels offsite and accessing the site through the MBTA right-of-way, the contractor can use a variety of techniques to mitigate noise and minimize disruptions to abutters:
- Use self-adjusting backup alarms, silencers or mufflers on equipment;
- limit truck and equipment idling;
- line dumping bins, hoppers and trucks with sound-deadening material;
- use noise blanket and shielding where possible; and
- response to noise complaints and monthly noise monitoring.
Special track work will be done in larger sections and requires work over weekends.
The MBTA will continue to notify abutters of the work in advance of the contractor reaching each construction area.
The schedule for this infrastructure project is weather dependent and subject to change without notice.
