   Every station other than Aqueduct is served at all times, but not by   
   every train.  For example, late nights the A runs local in Manhattan   
   and makes the stops that the C makes in the day.  During the day alternate   
   A trains go to Leffert's Blvd and the Rockaways, but after midnight they all   
   go to the Rockaways and there's a shuttle between Euclid Ave and Lefferts Blvd.   
      
   In general, every station is served every 20 minutes or better,   
   although I see a few places like the Rockaway shuttle with 26 minutes   
   between some trains.   
      
   There's also a lot of weekend closings for construction.  This weekend for   
   example there's no L service in Manhattan.

   Well, sort of.  From Penn Station to Jamaica, there's nothing between   
   3:18 and 4:54 AM and that ripples out to the rest of the system.
