R also uses that local track. If an R has to wait for a V to switch, that means two tracks are held as the homeballs approaching the switch clear (and an E makes the stop at Queens Plaza. F via 63rd is fine, but put the Q there, and it has to switch local before 36th...with the V and R already local. If either service has a train in the station, the Q has to wait to go local, thus delaying not only itself but the F as well (which has to switch onto the express and deals with the same thing, to a lesser degree with the E)...meanwhile al of this is going on, more V and R trains are on their way Peak tph is somewhere around 30, it'd be really difficult to handle the R, V, AND Q all running local. Plus the R and V relaying at CTL while the Q continues on (since they have to make sure there are no passengers on the trains relaying - it's non revenue track). It's just too many trains crossing paths and using the same track. |
