The Lexington Avenue Line is one of the lines of the IRT division of the New York City Subway, stretching from Downtown Brooklyn or Lower Manhattan north to 125th Street in East Harlem. [MTA Capital Construction, Second Avenue Subway, [http://www.mta.info/capconstr/sas/sdeis.htm Supplemental Draft Environmental Impact Statement] , PDFlink| [http://www.mta.info/capconstr/sas/documents/sdeis/chapter5b.pdf Chapter 5B: Transportation—Subway and Commuter Rail] |317 KiB ] The portion in Lower and Midtown Manhattan was part of the first subway line in New York. The line is served by NYCS service|4, NYCS service|5, and NYCS service|6 trains.

The line is also known as the IRT East Side Line, as it is the only line in Manhattan to directly serve the Upper East Side and East Midtown; this four-track line is the most used rapid transit line in the United States. Its average of 1.3 million daily riders is "more than the combined ridership of San Francisco and Boston's entire transit systems" (Second Avenue Subway FEIS, p. 1–6). Its ridership also exceeds that of the 798,456 daily trips on the entire Washington Metro.cite press release

The south end of the Lexington Avenue Line is near the East River, but its exact location is unclear. As of 2007, emergency exit signs label the two parts of Borough Hall as being along the IRT Broadway–Seventh Avenue Line and IRT Lexington Avenue Line. The chaining designations "K" (Clark Street Tunnel) and "M" (Joralemon Street Tunnel) join and become "E" (Eastern Parkway Line) at Borough Hall.

Several stations along this line have been abandoned. When platforms were lengthened to fit ten cars, it was deemed most beneficial to close these stations and open new entrances for adjacent stations. For example, 14th Street–Union Square has an entrance on 16th Street, and 23rd Street has an entrance on 20th Street, so 18th Street station was abandoned.

Extent and service

Services that use the Lexington Avenue Line are colored green. The following services use part or all of the Lexington Avenue Line:

The Lexington Avenue Line begins at the inner loop at South Ferry station, which is currently used to turn 5 trains at all times except rush hours. North of the station is a merge with the tracks of the Joralemon Street Tunnel from Brooklyn, which become the express tracks. These run north under Broadway and Park Row to Centre Street. At the south end of Center Street, directly under New York City Hall, is the abandoned City Hall loop and station, which was the southern terminus of the original IRT subway line. The loop is still used to turn 6 service; the Lexington Avenue local tracks, which feed the loop, rise up to join the express tracks just south of Brooklyn Bridge–City Hall station.

From Brooklyn Bridge, the line continues northward in a four-across track layout under Centre Street, Lafayette Street, Fourth Avenue, and Park Avenue South until 42nd Street. At this point, the beginning of Metro-North Railroad's Park Avenue tunnel in Grand Central Terminal forces the Lexington Avenue Line to shift slightly eastward to Lexington Avenue; its 42nd Street–Grand Central station is located on the diagonal between Park and Lexington. Just south of Grand Central, a single non-revenue track connects the IRT 42nd Street Shuttle to the southbound local track; this was part of the original IRT subway alignment.

Under Lexington Avenue, the line assumes a two-over-two track configuration, with the local tracks running on the upper level and the express on the lower, although it briefly returns to a four-across layout between 96th Street and 116th Street stations. 125th Street station maintains this two-over-two layout, although here the upper level is used by northbound trains (both local and express) and the lower level by southbound trains (again, both local and express). North of 125th Street, a flying junction marks the end of the line, where it splits into the IRT Jerome Avenue Line (4 and 5) and the IRT Pelham Line (6 and NYCS service|6|<6>).

History

The part of the line from City Hall to just south of 42nd Street was part of the original IRT line, opened on October 27, 1904. An extension to Fulton Street opened at 12:01 a.m. on January 16, 1905. The next station, Wall Street, was opened on June 12, 1905. [http://nycsubway.org/irt/tenyears.html]

The first revenue train on the South Ferry extension left South Ferry at 11:59 p.m. on July 9, 1905; the extension of the IRT White Plains Road Line to West Farms opened just after. The first train ran through the Joralemon Street Tunnel to Brooklyn about 12:45 a.m. on January 9, 1908.

The original plan for what became the extension north of 42nd Street was to continue it south through Irving Place and into what is now the BMT Broadway Line at Ninth Street and Broadway. Contracts awarded on July 21, 1911 included Section 6 between 26th Street and 40th Street; at the time, the IRT had withdrawn from the talks, and the Brooklyn Rapid Transit Company (BRT) was to operate on Lexington Avenue. The IRT submitted an offer for what became its portion of the Dual Contracts on February 27, 1912, [James Blaine Walker, [http://books.google.com/books?vid=OCLC03638541&id=lpEgAAAAMAAJ Fifty Years of Rapid Transit, 1864-1917] , published 1918, pp. 230-233] and construction was soon halted on Section 6. [New York Times, [http://select.nytimes.com/gst/abstract.html?res=F00811FB3E5813738DDDAB0A94DD405B828DF1D3 Petition for Subway in Lexington Ave.] , May 22, 1912, page 11]

The rest of the line, north to 125th Street, opened on July 17, 1918. However, until the evening of August 1, 1918, it ran as a shuttle on the local tracks only, terminating at 42nd Street and at 167th Street on the IRT Jerome Avenue Line (where the connection from the elevated IRT Ninth Avenue Line merged). On August 1, service patterns were changed, and the Lexington Avenue Line became a through route. The IRT Broadway–Seventh Avenue Line also switched from shuttle operation at that time, and the IRT 42nd Street Shuttle was formed along the old connection between the sides. Due to the shape of the system, it was referred to as the "H system". Also on August 1, the first section of the IRT Pelham Line opened to Third Avenue–138th Street.
