Chestnut Hill Avenue station

Chestnut Hill Avenue 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 trolley to catch fire. No injuries were reported, but the trolley suffered significant damage.
