Keep in mind subways will be operating on a holiday schedule Monday ("President's Day"). Those of us with the misfortune of working for employers who hate presidents should take note.
The 2/3: Running normally in Brooklyn, they take over the 1's duties in Manhattan, and run local between Chambers and 96th streets. In protest, the 1 refuses to stop anywhere between 14th and Chambers, and the downtown 1 goes even farther and skips stops between 34th and 14th streets. I don't understand it either.
The A: Running locally between Euclid Avenue in Brooklyn and 168th Street in
the Bronx Manhattan. Downtown/Brooklyn-bound trains skip 50th, 23rd and Spring Streets in Manhattan. Please plan accordingly.
The C: Again, it won't be running at all. Listen to Strayhorn and take the A train.
The F: Brooklyn-bound trains skip York Street in Brooklyn, as well as 2nd Ave, Delancey St, East Broadway, and Broadway/Lafayette in Manhattan. DUMBOners returning from Manhattan should take the A to High street and walk the extra few blocks.
The N: Manhattan-bound trains run on the D line between Stillwell Avenue and 36th Street. All N stops in between are screwed. Consult the MTA's Weekend Service Advisory for alternate travel suggestions, or for more details on other subway disruptions.
