It’s my understanding the the DPU’s always follow the lead locomotive’s controls. Would there ever be senarios when it would be nice to control them seperatly? For example during hilly territoy, maybe an engineer would like less or more dynamic brakes on the rear than on the front. Or more or less power in certain situations.
Is this idea just too complicated and not really wanted or needed? ideas?
Yes, of course, that is why the can be controlled and not just put on line. And for the very reasons you cite.
Wonder why nobody’s corrected your impression yet. The engineer (always?) has the choice of controlling the DPU separately or with the head end units. Putting up the fence, it’s called-- no idea how complicated the switchover is, but I’m guessing not very.
Thanks, I quess I just never knew for sure how they were exactly controlled.
Absolutely. You don’t want to be tipping a hill, with the remotes still going up hill and go into DB, could rip the train apart. The engineer can have the remotes pushing while the head end is in DB until the remotes tip the hill, then he can synch them up again.
Question: Is DPU used yet where there are two sets of DPU? If so has lead control software been developed so each section of DPU can be run separately?
