The 21st Street–Queensbridge station is a station on the IND 63rd Street Line of the New York City Subway. Located at the intersection of 21st Street and 41st Avenue within Queensbridge in Long Island City, Queens, it is served by the F train at all times and the <F> train during rush hours in the reverse peak direction. The station contains two tracks and two side platforms, connected by an overhead mezzanine. It opened in October 1989 with the opening of the 63rd Street Line. From its opening until 2001, this was the terminal of the line, although it was not originally intended as a terminal station. The 63rd Street Line was originally part of a plan for a Queens Bypass Line running along the Long Island Rail Road Main Line. However, due to a lack of funds, the line terminated here, with layup tracks going up to 29th Street. As a result, the tunnel became known as the "tunnel to nowhere." In December 2001, the 63rd Street Tunnel Connection opened, allowing trains from the IND Queens Boulevard Line to use the line. This station then became a through station, serving express F trains since then. From Wikipedia
