Overview
- The swap took effect at 6 a.m. Monday and runs on weekdays until 9:30 p.m., with late-night and weekend service unchanged.
- F trains now serve Queens Plaza, Court Square–23rd Street, Lexington Avenue/53rd Street and Fifth Avenue/53rd Street, while M trains take over 21st Street–Queensbridge, Roosevelt Island, Lexington Avenue–63rd Street and 57th Street.
- Officials say rerouting removes bottlenecks where E, F, M and R trains previously crisscrossed at Queens Plaza, improving performance across the lines.
- Roosevelt Island riders face the biggest adjustment as their primary link shifts to the M on weekdays before reverting to the F overnight and on weekends.
- Early reactions are mixed, with some commuters expecting smoother trips and others reporting confusion or frustration, including concerns about map accuracy.
