The K Eighth Avenue Local, earlier the AA, was a rapid transit service of the New York City Subway. Its route bullet was colored blue on station signs, car rollsigns, and the official subway map since it ran on the IND Eighth Avenue Line.

The K operated during midday, evenings, and weekends, making all local stops between 168th Street in Washington Heights, Manhattan and World Trade Center in Lower Manhattan via Central Park West and Eighth Avenue in Manhattan. During late night hours, the A express made local stops on the IND Eighth Avenue Line. During rush hours, the C, formerly the CC, ran between Bedford Park Boulevard and Euclid Avenue, replacing the K as the local on Eighth Avenue. It was discontinued in 1988 as part of a series of major service changes.



Service as the AAEdit

Sixth Avenue Subway Will Be Opened to the Public at 12-01 A.M. Sunday, Dec 15, 1940

A and AA service began on September 10, 1932 with the opening of the IND Eighth Avenue Line. The Independent Subway System (IND) used single letters to refer to express services and double letters for local services. The A ran express and the AA ran local, from 168th Street to Chambers Street/World Trade Center, known at the time as Hudson Terminal. The AA ran at all times, and it was extended to 207th Street during nights and on Sundays when the A did not run. When the Eighth Avenue Line was extended to Jay Street–Borough Hall on February 1, 1933 the AA was extended there, but only during the times when the A didn't run; it continued to terminate at Chambers Street when the A did run.[1][2]

On July 1, 1933, the AA was suspended when the Concourse Line opened and the new CC service provided local service on Eighth Avenue in its place. The AA was suspended until the IND Sixth Avenue Line opened on December 15, 1940. The AA only ran during non-rush hours and Saturday late afternoon through all day Sunday service to Chambers Street. Rush hours, which at the time included Saturday mornings and afternoons, the AA did not run; it was replaced by the BB (later B) service, which instead ran on the Sixth Avenue Line.[3] This pattern was unchanged until August 28, 1977, when late night service was replaced by an all local A service.[1][2][4]

Service as the KEdit

This brochure was published in 1985 to explain the relabeling of double-letter subway services, including the creation of the K.

On May 6, 1985, as part of the elimination of double letters, the AA was renamed the K. This service operated between 168th Street and World Trade Center during midday, evenings, and weekends. During late night hours, the A express made local stops on the Eighth Avenue Line. During rush hours, the C, formerly the CC, ran between Bedford Park Boulevard and Rockaway Park–Beach 116th Street, replacing the K as the local on Eighth Avenue.[5] This change was not officially reflected in schedules until May 24, 1987.[2]

On December 11, 1988, as part of the widespread service changes that day, the K was discontinued, being replaced by the C train, which was expanded from its rush-hour only service to include midday service between 145th Street and Euclid Avenue, early evening (until 9:00) service from 145th Street to World Trade Center, and weekend service matching the former K between 168th Street and World Trade Center.[6] The B was also expanded to middays to match part of the former K.[7][2]
