K (Eighth Avenue Local)

The K Eighth Avenue Local, earlier the AA, was a New York City Subway service. It was designated with a blue circle on station signs, car rollsigns, and the official subway map since it ran on IND Eighth Avenue Line.

History

An R42 K train at Chambers Street

In 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 Euclid Avenue, replacing the K as the local on Eighth Avenue.

The K last ran on December 10, 1988, and the next day, the C was expanded from its rush-hour only service to include midday service between 145th Street and Euclid Avenue, early evening (until 21:00) service from 145th Street to World Trade Center, and weekend service matching the former K between 168th Street and World Trade Center.
