Shawmut station
Shawmut station is a subway station in Boston, Massachusetts. It serves the Ashmont branch of the MBTA's Red Line. It is located on Dayton Street in the Dorchester neighborhood. The station, the only underground station on the Red Line south of Andrew station, sits in a shallow cut-and-cover subway tunnel that runs from Park Street south to Peabody Square where it surfaces at Ashmont station. Shawmut opened along with Ashmont on September 1, 1928, as part of a southward extension of the Cambridge–Dorchester line. Shawmut station has two side platforms serving the line's  two tracks. The headhouse connects the two platforms and serves as a free crossover between them, with two elevators from the paid lobby to each platform. Emergency exits near the south end of the platforms lead to small brick buildings on the entrance plaza. Shawmut does not have any direct bus connections because the station is located in a residential neighborhood away from major streets. It is one of a small number of MBTA heavy rail subway stations without direct bus connections. History. Shawmut Branch Railroad. In 1872, the Old Colony Railroad took over the Shawmut Branch Railroad, which branched  off the main line at Harrison Square and ran through Dorchester to Milton. The branch line originally included stations at Melville Avenue and Centre Street, just one-quarter mile apart, which were consolidated into Shawmut station on October 11, 1884. Shawmut station was located between Mather and Centre streets on the east side of the tracks. The New York, New Haven and Hartford Railroad acquired the Old Colony and took over operations in 1893. In 1924, the Boston Elevated Railway bought the Shawmut Branch Railroad and part of the Milton Branch in preparation for extending the Cambridge–Dorchester line, although  New Haven trains ran on the line until 1926. Rapid transit conversion. The Shawmut Branch reopened as a rapid transit extension in two sections: to Fields Corner (with intermediate stops along the Old Colony mainline at Columbia and Savin Hill) in November 1927, then further to Ashmont with an intermediate stop at Shawmut on September 1, 1928. The Cambridge–Dorchester line became the Red Line in August 1965. The station was retrofitted in 1981 to accommodate six-car trains, which started service in 1988. The station was originally built with 420-foot platforms, making in the only pre-WWII station  on the line designed for six-car trains. The MBTA issued a $4.3 million design contract for renovations of Ashmont, Shawmut, and Fields Corner stations on May 3, 2001. Shawmut and Fields Corner reached 100% design by January 10, 2003; Ashmont was delayed due to design changes. The MBTA broke ground for the Red Line Rehabilitation Project – a $67 million reconstruction of Shawmut, Fields Corner, and Savin Hill stations – in October 2003. Construction began in March 2004. Unlike the other two stations, which were completely rebuilt, Shawmut received more modest changes. Extensions in the original style were built  on both sides of the headhouse to accommodate redundant elevators for accessibility, required by the Americans with Disabilities Act of 1990. The historic headhouse and platforms were also restored, and new landscaping built around the station for walkability and noise control. Original plans to include public art as part of the Arts on the Line program were removed in budget cuts; only historical interpretive panels were installed. The modernization was completed in 2009.
