City Square station was an elevated rapid transit station located at City Square in the Charlestown section of Boston, Massachusetts. It was part of the Charlestown Elevated, which was open from 1901 to 1975.
The Charlestown Elevated opened on June 10, 1901. City Square station originally had a single island platform about long – enough for three-car trains.[1] The platform was lengthened northward three times to accommodate longer trains. An extension to for four-car trains was constructed in October–November 1901. Extension for five-car trains took place in early 1905, and for six-car trains in November 1908.
The 1908 extension was only temporary; a larger reconstruction of the station was needed to serve eight-car trains.[2] Two side platforms were built to replace the island platform. Work took place in 1909; train service was not interrupted during construction.[3] [4]
The Main Line Elevated, of which the Charlestown Elevated was the northern leg, was operated by the Boston Elevated Railway until 1947. It was operated by the Metropolitan Transit Authority (MTA) from 1947, then by the Massachusetts Bay Transportation Authority (MBTA). The MBTA renamed the line as the Orange Line in 1967. The Charlestown Elevated was closed on April 4, 1975, and replaced by the Haymarket North Extension.
