63rd Street Shuttle
Two of the shuttles ran along the IND Sixth Avenue Line.
The first shuttle, designated with an orange S, began in May 1997. It ran late nights only from 21st Street – Queensbridge to Second Avenue via the IND 63rd Street Line and IND Sixth Avenue Line making local stops. Prior to that, the F train served the IND 63rd Street Line during late nights. This service was suspended in February 1998 when construction suspended service between the 63rd Street Line and the Sixth Avenue Line, but it resumed in May 1999 when the construction was completed. It was discontinued in 2000 when preparation for full-time service on the IND 63rd Street Connector began.
The second shuttle, also with an orange bullet, began on July 22, 2001 due to the closure of the north tracks on the Manhattan Bridge. It ran between 21st Street – Queensbridge and Broadway – Lafayette Street, running an almost identical route to the first. Unlike the first shuttle, this shuttle ran at all times, replacing the B and Q trains which previously served the IND 63rd Street Line during daytime hours. On December 16, 2001, the 63rd Street connector to the IND Queens Boulevard Line opened and the F train was rerouted to serve the IND 63rd Street Line at all times, permanently replacing this shuttle. At the same time, the Grand Street Shuttle was lengthened to West Fourth Street – Washington Square.
This service, designated with a yellow S, ran at all times during reconstruction of the IND 63rd Street Line between 1998 and 1999 and was one of the very few regularly scheduled services to use the BMT 63rd Street Line. Service began on February 22, 1998, running between 21st Street – Queensbridge and 57th Street – Seventh Avenue on the BMT Broadway Line. On April 6, it was extended to 34th Street – Herald Square on weekdays, skipping 49th Street. This replaced B and Q trains, and the original late-night shuttle that had used the IND 63rd Street Line; they were truncated to 57th Street – Sixth Avenue (which was closed late nights). Once work was completed on May 22, 1999 this shuttle was discontinued, and B and Q trains and the late-night shuttle returned to using 21st Street – Queensbridge as their terminal.
