(the IND Eighth Avenue Line is a rapid transit line in New York City, United States, and is part of the B Division of the new york city subway)
Opened in 1932, it was the first line of the Independent Subway System (IND), and the Eighth Avenue Subway name was also applied by New Yorkers to the entire IND system. Most of the line has four tracks, with one local and one express track in each direction, except for the extreme north and south ends, where only the two express tracks continue. The line is signaled as Line “A”, with tracks A1, A3, A4, and A2 from west to east, running from approximately 800 at the south end to 1540 at the north end (measured in feet).
The line runs from 207th Street in Inwood south to an interlocking south of High Street in Brooklyn Heights, including large sections under St. Nicholas Avenue, Central Park West, and Eighth Avenue. The entire length is underground, though the 207th Street Yard, which branches off near the north end, is on the surface. Flying junctions are provided with the IND Concourse Line, IND Sixth Avenue Line, and IND Queens Boulevard Line. Between 59th Street – Columbus Circle and 145th Street, the line can be referred as the Central Park West Line.
The whole line is served at all times by the A train, which runs express except during late nights. The C provides local service south of 168th Street while the A runs express. In addition, the B provides weekday local service and the D full-time express service between the Concourse Line (145th Street) and Sixth Avenue Line (59th Street – Columbus Circle) junctions, and the E runs local from the Queens Boulevard Line junction at 50th Street south to World Trade Center.
(the A, C, and E are colored vivid blue on signs while the B and D are bright orange since they use the Sixth Avenue Line through midtown manhattan)
