IND Fulton Street Line

The IND Fulton Street Line is a rapid transit line of the IND Division of the New York City Subway, running from the Cranberry Street Tunnel under the East River through central Brooklyn to a terminus in Ozone Park, Queens. The IND Rockaway Line branches from it just east of Rockaway Boulevard. The A train runs express during daytime hours and local at night on the underground portion of the line; it runs local on the elevated portion of the line at all times. The C train runs local on the underground portion of the line at all times except late nights.

The line runs primarily along Fulton Street, Pitkin Avenue, and Liberty Avenue. The underground portion, which constitutes the majority of the line, was built for the city-owned Independent Subway System (IND), opening between 1936 and 1956. The elevated portion in Queens was originally part of the Brooklyn–Manhattan Transit Corporation (BMT)'s Fulton Street elevated line; the Elevated in Brooklyn was closed and demolished in stages with the opening of the subway line.
