L (New York City Subway service)

The L 14th Street–Canarsie Local is a rapid transit service in the B Division of the New York City Subway. Its route emblem, or "bullet", is colored medium gray since it serves the BMT Canarsie Line.

The L operates at all times between Eighth Avenue in Chelsea, Manhattan, and Rockaway Parkway in Canarsie, Brooklyn. It also briefly enters Queens at Halsey Street, serving the neighborhood of Ridgewood. It is the first New York City Subway service to be automated using communications-based train control.

The L commenced its current route and service pattern upon completion of the Canarsie Line in 1928. Express trains formerly ran along the L's trackage in central Brooklyn, running along the BMT Fulton Street Line in eastern Brooklyn, but were discontinued in 1956. Since then, the L has been entirely local.

The L was originally the Brooklyn–Manhattan Transit Corporation's 16 service. The 16 became the LL in 1967 and then the L in 1985. In the early 2000s, the L saw a dramatic increase in ridership since many neighborhoods along the route have experienced gentrification. From April 2019 to April 2020, late-night and weekend L service between Manhattan and Brooklyn was temporarily reduced as part of the 14th Street Tunnel shutdown, which sought to repair damage to the 14th Street Tunnel incurred by Hurricane Sandy in 2012.
