After the first subway line was completed in 1908, the station was served by local trains along both the West Side (now the Broadway–Seventh Avenue Line to Van Cortlandt Park–242nd Street) and East Side (now the Lenox Avenue Line). West Side local trains had their southern terminus at City Hall during rush hours and South Ferry at other times, and had their northern terminus at 242nd Street. East Side local trains ran from City Hall to Lenox Avenue (145th Street). In 1918, the Broadway–Seventh Avenue Line opened south of Times Square–42nd Street, thereby dividing the original line into an "H" system. The original subway north of Times Square thus became part of the Broadway–Seventh Avenue Line, and all local trains were sent to South Ferry.
