Chestnut Hill Avenue station is a light rail surface stop on the MBTA Green Line B branch, located in the median of Commonwealth Avenue just east of Chestnut Hill Avenue in the Brighton neighborhood of Boston, Massachusetts. Chestnut Hill Avenue has two low-level platforms, serving the B branch's two tracks; the stop is not accessible.
Just to the west of the station, there is a wye connecting the B branch to non-revenue tracks that run along Chestnut Hill Avenue to Reservoir Carhouse at Cleveland Circle. The tracks are used to supply the B branch with cars before rush hour, as the carhouse at Boston College has limited storage area. The leg of the wye leading from the westbound B branch to the non-revenue tracks is out of service and paved over.
On May 14, 2008, an outbound train derailed at Chestnut Hill Avenue. It struck a nearby utility pole, which brought down the overhead wires, causing the light rail vehicle to catch fire. No injuries were reported, but the vehicle suffered significant damage.[1] [2]
Track work in 2018–19, which included replacement of platform edges at several stops, triggered requirements for accessibility modifications at those stops.[3] Design for Chestnut Hill Avenue and four other B Branch stops was 30% complete by December 2022.[4] A design shown in March 2024 called for Chestnut Hill Avenue station and South Street station to be consolidated, with a single station located between Chestnut Hill Driveway and Chestnut Hill Avenue.[5] In May 2024, the Federal Transit Administration awarded the MBTA $67 million to construct accessible platforms at 14 B and C branch stops including the combined Chestnut Hill Avenue/South Street station., construction is expected to start in fall 2025.[6]
