The Massachusetts Bay Transportation Authority (MBTA) recently completed the Green Line D Branch Track and Signal Replacement Project.
The project is part of the Green Line Transformation program. The goal is to improve track conditions and signal efficiency as well as reduce delays caused by maintenance and the need for repairs. On the D Branch, 25,000 feet of track and 6.5 miles of signals have been replaced since June 2018.
During 2017 and 2018, outdated signals were responsible for 120 signaling incidents on the D Branch, and the average age of the tracks was more than 30 years old.
“We’re excited to see the completion of this project, bringing improvements to D branch riders through safer, more reliable Green Line service,” Steve Poftak, MBTA General Manager, said. “While the completion of this project is a successful milestone for Capital Transformation, we also recognize that more work needs to be done. We’re committed to making the Green Line fully accessible, and we ask for the community’s continued patience and support while we work towards this goal of improving the overall rider experience for all.”
Much of the old signal infrastructure was installed in the 1950s. The new equipment is digital, making it easier to maintain and monitor.
