K (Manhattan Local)

The K Eighth Avenue Local, earlier known as 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, as it operated on the IND Eighth Avenue Line.

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