The station originally opened on November 30, 1908, along with the rest of the Washington Street Tunnel. At this time, the
Boston Elevated Railway's Main Line (which later became the
Orange Line) was moved from the
Tremont Street Subway into this new subway tunnel. As with the other stations of the Washington Street Tunnel, the platforms were largely separated and given different names -
Boylston for the southbound platform, and
Essex for the northbound side. On February 11, 1967, as part of a larger renaming of Orange Line stations, the entire station became
Essex (to distinguish it from the
Green Line's
Boylston station to the west). On November 27, 1972, two robbers killed an MBTA porter while looting the fareboxes at the station. In May 1972, the MBTA opened a new southbound headhouse to accommodate a realignment of Boylston Street. That month, the agency received a federal grant that funded two-thirds of a $14.3 million modernization program. As part of that project, the MBTA investigated the feasibility of connecting Essex, ,
Washington, and with pedestrian tunnels. (The
Winter Street Concourse was opened to passengers in 1979, connecting Park Street and Washington, but Essex and State were never connected with the others.) A $378,323 contract for modernization work on the southbound side, including a platform extension, was awarded in 1975; the Lagrange Street and Hayward Place entrances were likely closed during the work. As part of the renovation,
George Greenamyer constructed an , artwork on the southbound platform in 1976. The first sculpture in
the MBTA's arts program, it was styled after an old
steam locomotive, and incorporated scrapped locomotive and truck parts. The three locomotive driving wheels were recast from original wood molds owned by the
Edaville Railroad. A $3.3 million modernization of the northbound side was approved on April 2, 1986, with a groundbreaking held on May 30. The project added an elevator to the northbound platform and a new entrance north of Essex Street; the Essex Street headhouse was closed. An extension of the northbound platform was completed shortly before six-car train service began on August 18, 1987. Katayama wrote that "I instantly heard the voice of this station telling me...to relieve the darkness with a range of bright colors." On May 4, 1987, the station was renamed
Chinatown concurrent with the opening of the
Southwest Corridor; the change (likely an effort to rebrand the declining
Combat Zone) had been approved in 1985 as part of a series of station name changes. A simultaneous station renovation included a rebuilt headhouse and a new elevator built into the new development. The $5 million project, completed in 2002, made the station fully
accessible.
Silver Line service on Washington Street between Dudley and Downtown Crossing (now route SL5) started on July 20, 2002. Additional service to South Station (route SL4) began on October 15, 2009. Both routes operate on one-way loops in downtown Boston, serving Chinatown station only in the northbound direction. In May 2020, the MBTA awarded a $8.75 million design contract for accessibility renovations at both Chinatown and stations. The work at Chinatown includes reopening the Hayward Place and Lagrange Street entrances with added elevators, replacement of the existing elevators, and lobby renovations. The entire Orange Line, including Chinatown station, was closed from August 19 to September 18, 2022, during maintenance work. ==References==
