53rd Street Tunnel

Route

West of 36th Street, the F uses a different service pattern depending on the time of day, continuing along the 53rd Street Tunnel on weekdays during the day, and using the IND 63rd Street Line on nights and weekends. The two-track 63rd Street Line (F and ​M trains) splits from both sets of tracks at a flying junction, running to Manhattan under 41st Avenue. The Queens Boulevard Line continues under Northern Boulevard to Queens Plaza (E, ​F, <F>, and ​R trains) before splitting into three parts at another flying junction. The express tracks (E, ​F, and <F> trains) continue towards Manhattan under 44th Drive, while the local tracks split two ways, with the 60th Street Tunnel Connection (R train) turning northwest and the IND Crosstown Line (no regular service) remaining under Jackson Avenue (Northern Boulevard south of Queens Plaza). From this point on, the Queens Boulevard Line has only two tracks.
