Even on the D train dash from 59th to 125th street during non rush likely don't get much north of 45-50 (based strictly on my impression, no inside knowledge). I remember reading that the modern equipment could theoretically go faster than 60mph, but I doubt they ever in normal service get near that, for a number of reasons (actually interesting question, maybe one of those with knowledge know, do they have any kind of governor on subway cars to keep them from going above a certain speed? Not talking the track tripper system/speed control, I mean the top end, like they have on many cars to keep them within the speed rating of the tires.
