In the late 19th century, the Old Colony Railroad train station was located at the end of Crescent Avenue, about two blocks south of the current JFK station on the MBTA’s Red Line. The Old Colony Railroad was constructed along Dorchester’s eastern boundary in the 1840s. The stations in Dorchester were at Crescent Avenue, Savin Hill, Pope’s Hill, and the Shawmut Branch Railway had stations at Fields Corner, Shawmut and Ashmont and Neponset.
