63rd Street Shuttle
63rd Street Shuttle (Sixth Avenue) – 1997
The first shuttle, designated with an orange S, began in May 1997. It ran late nights only from 21st Street – Queensbridge to Second Avenue as an all local route. Prior to that, the F train served the IND 63rd Street Line during late nights. This service was suspended in February 1998 when construction required suspension of service on the 63rd Street Line from the Sixth Avenue Line, but 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.
63rd Street Shuttle (Broadway) – 1998
This service, designated with a yellow S, ran at all times during reconstruction of the IND 63rd Street Line and was one of the very few regularly scheduled services that have used 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 that had used the IND 63rd Street Line; they were truncated to 57th Street – Sixth Avenue (which was closed late nights). Work was completed on May 22, 1999, the shuttle was discontinued, and B and Q trains returned to 21st Street.
Sixth Avenue Shuttle – 2001
This service, with an orange S, served the IND 63rd Street Line and IND Sixth Avenue Line local tracks, running between 21st Street – Queensbridge and Broadway – Lafayette Street. Service began on July 22, 2001 due to the closure of the north tracks on the Manhattan Bridge. On December 16, 2001, the 63rd Street connector to the IND Queens Boulevard Line opened and a rerouted F service replaced this shuttle. At the same time, the Grand Street Shuttle was lengthened to West Fourth Street – Washington Square.
