Not that you should ever expect the F to shuttle you anywhere without taking an underground siesta or morphing into a whole new train or something, but expect a little nighttime shakeup onboard next week. The city's most delayed subway line's getting the FASTRACK treatment starting Monday, with no overnight service between Broadway-Lafayette Street and York Street.

The MTA says they'll be doing extensive repair and maintenance work from 10 p.m. to 5 a.m. Monday through Friday, with service affecting F stops in Lower Manhattan as well as York Street in Brooklyn. As always, free shuttle buses will run between the Broadway-Lafayette Street and East Broadway stops, and between York Street and Jay St-MetroTech in Brooklyn. Thankfully, borough-hopping won't be a complete nightmare, since the F will be rerouted along the A line in both directions between West 4th Street and Jay Street-MetroTech.

In other fun subway news, the 7 continues its hellacious tirade against weekend travel by once again not running between Times Square-42nd Street and Queensboro Plaza in both directions. This joy starts at 2 a.m. on Saturday and runs through 4:30 a.m. on Sunday; free shuttle buses will service stops between Vernon Boulevard-Jackson Ave and Queensboro Plaza.
