Morton Street is a commuter rail station on the MBTA Commuter Rail Fairmount Line, located at 865 Morton Street (MA 203) in the Mattapan section of Boston, Massachusetts. With two full-length high-level platforms and ramps to the street, the station is fully wheelchair accessible. The station was reconstructed in 2006, with the official reopening in 2007.HistoryService on the Fairmount Line began in 1855 and lasted until 1944. The service included a stop at Morton Street, originally known as Forest Avenue.The Dorchester Branch was reopened as a bypass in November 1979 during Southwest Corridor construction, including stops at Uphams Corner, Morton Street, and Fairmount. However, Uphams Corner and Morton Street were dropped in January 1981 as part of systemwide cuts. Morton Street was originally built at minimal cost, with small low-level platforms and staircases to Morton Street. The station was not handicapped accessible, since service over the route was intended to be temporary; however, it was popular with residents of the communities the line passed through. When the Southwest Corridor reopened on October 5, 1987, the Fairmount Line shuttle service was retained, with Uphams Corner and Morton Street reopened.
