Mostly, on the NEC we use them for making high speed station stops to save on brake shoe wear and not piss the air away making a lot of on and off with the automatic brake. There is of course, more than one way to skin a cat so your operators behaviors may vary.I guess this is where we can say something positive about the ACS64s, the dynamic/regen works wonderful. On dry rail you can almost bring a train to a stop without touching the air, I know the majority of the time I hardly touch the air for minor speed changes on 9 cars or less on a good day.
