The data doesn't make sense to me, at least if it doesn't take into consideration transfers (which are very erratic from my experience).
Ex: The A in general goes express from 125th to 59th st without any stops. Therefore, one would think those stations should be sort of disconnected from each other (sort of islands in the the graph), but the data as presented shows them with a simple gradual extension of time.

makes me wonder about its accuracy in general.
