The Astoria Line is a rapid transit line of the BMT division of the New York City Subway, serving the neighborhood of Astoria, Queens. It runs south from Ditmars Boulevard in Astoria to 39th Avenue in Long Island City along 31st Street. It then turns west and serves Queensboro Plaza over Queens Plaza.
The entire line is served by the N train at all times, joined by the Q on weekdays. It was built as part of the Dual Contracts and jointly operated by the IRT and BMT using IRT-sized cars until 1949, when the platforms were shaved to accept the wider BMT cars and joint service was discontinued.
The north end of the Astoria Line is a two-track terminal at Ditmars Boulevard, with one island platform. South of the station, the center express track, currently not used in revenue service, begins (with crossovers to allow terminating trains to reach the correct track). The next station, Astoria Boulevard, is the only express station on the three-track section. The next four stations are local ones with two side platforms.
South of 39th Avenue, the express track merges with the two outer tracks. The line then curves west and enters Queensboro Plaza, a dual-level station with northbound trains on the upper level, southbound trains on the lower level, and cross-platform transfers to the IRT Flushing Line. Crossover tracks exist between the upper level tracks just north of the station, one of a few connections between the BMT / IND and IRT. After Queensboro Plaza, the line ramps underground, and merges with the 60th Street Tunnel Connection to become the BMT Broadway Line via the 60th Street Tunnel to Manhattan.
The Astoria Line was originally part of the IRT, as a spur off the IRT Queensboro Line, now the IRT Flushing Line. The whole line north of Queensboro Plaza opened on February 1, 1917 and was used by trains between Grand Central and Astoria. Through IRT service to the Corona Line (now the Flushing Line) began two months later on April 21.
On July 23, 1917, the Queensboro Bridge spur of the elevated IRT Second Avenue Line opened. At that time, all elevated trains to Queensboro Plaza used the Astoria Line while all subway trains used the Corona Line, though this was later changed with trains alternating between branches.
The 60th Street Tunnel opened on August 1, 1920, allowing BMT trains to reach Queensboro Plaza. However, the stations on the Astoria and Corona Lines were built to IRT specifications, which were too narrow for BMT rolling stock. As a result, those trains terminated at Queensboro Plaza using a relay track east of the station to turn around for the return trip to Manhattan.
On April 8, 1923, the BMT, using elevated cars, started running shuttles along the Astoria (numbered BMT 8 in 1924) and Corona Lines (BMT 9) in addition to the existing IRT service. On June 23, 1942, the IRT Second Avenue Line spur to Queensboro Plaza closed.
The IRT services were numbered in 1948, with 7 being assigned to the Flushing Line and 8 to the Astoria Line. A year later on October 17, 1949, the Flushing Line became IRT-only. The platforms on the Astoria Line were shaved back to allow through BMT trains to operate on it, the first ones being the Brighton Local (BMT 1) weekdays & Broadway - Fourth Avenue Local (BMT 2) at all times. Since then, the Astoria Line has hosted the northern end of various services running from Brooklyn through Manhattan; see B, N, Q, R, T and W for details.
