The station opened in 1846 as part of the Lexington and West Cambridge Railroad. It was damaged by fire on November 24, 1918.[2] Although a new station was planned, the old station was instead restored in 1921–22.[3] These renovations, designed by Kilham, Hopkins & Greeley, included a cupola and colonnade.[4]
The line became part of the Massachusetts Bay Transportation Authority (MBTA) Commuter Rail system in the 1960s, though the station building was converted to a bank by 1968.[5] In January 1977, following a major snowstorm which temporarily shut down the Lexington Branch, the MBTA announced that service on the branch would not be restored;[6] in the 1980s, the MBTA planned to extend the Red Line to Route 128 along the former path of the Lexington Branch as part of the Northwest Extension, including service to Lexington station, but fierce opposition from the residents of Arlington scuttled this plan, and the Northwest Extension was cut short to Alewife.
The building now serves as the headquarters of the Lexington Historical Society.[6] The Minuteman Bikeway runs through the former trainshed adjacent to the former station platforms.[7] Lexington and Bedford Depot are the only remaining station buildings from the Lexington Branch.
