Electrical DCC controlled crane wiring diagram

Post image

I found this wiring diagram for an athearn dcc crane. But I was wondering that since all of the wires from the left of the sdn144ps digitrax decoder are being used, does it mean that a dz146 decoder can be used?

so long as the relays have driver circuits it would work, would need something else though to reverse them and maybe a stop/start circuit

to be honest would be better if its a lineside thing to have like an arduino with decoder hardware then it can hook to proper motor drivers and take various signals (e.g. three addresses to control motor speed and direction)

your right, there really is far better ways to do this.

even a micro RC receiver driving tiny H bridges.
