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.[1] 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.[2][3]
