The C Eighth Avenue Local is a rapid transit service in the B Division of the New York City Subway. Its route emblem, or "bullet", is since it uses the IND Eighth Avenue Line in Midtown Manhattan. The C operates at all times except late nights between 168th Street in Washington Heights, Manhattan, and Euclid Avenue in East New York, Brooklyn, making all stops along its entire route. During late night hours, the train, which runs express along the entire C route during daytime hours, makes all stops. Historically, most C service ran only during rush hours, along the IND Concourse Line to Bedford Park Boulevard in the Bronx and later along the IND Rockaway Line to Rockaway Park–Beach 116th Street in Queens. Prior to 1985, the local C service was referred to as the CC, with the C designation reserved for a complementary express service that was discontinued in 1949. The CC was once the only route to serve the Bronx, Manhattan, Brooklyn, and Queens in a single trip. Outside of rush hour, local service in Manhattan was usually provided by the AA, later relabeled K, which ran between 168th Street and Chambers Street/World Trade Center. In 1988, the K and C were consolidated into one service, and during the 1990s, the C's routing was altered to create the current service pattern. , the C has a daily ridership of 250,000. History Original IND service The AA and CC services were the predecessors to the current C service. A and AA service began on September 10, 1932 with the opening of the first line of the Independent Subway System (IND), the Eighth Avenue Line. The 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. On February 1, 1933, the AA was extended to the newly-opened Jay Street–Borough Hall station when the A did not run, continuing to terminate at Chambers Street when the A did run. The C and CC services began operation on July 1, 1933 when the IND Concourse Line opened. The CC provided local service between Bedford Park Boulevard and Hudson Terminal
