I'm wrestling with wiring an Atlas uncoupling track to an SC-2 for remote operation. I am running in command mode with one power supply for track power and a separate power supply for accessories (switches). Since the uncoupler inherently uses track ground (outer rail), do I need to tap into track power for the uncoupler or do I cross the grounds and use accessory power (so it doesn't impact track voltage) with the track ground? I'm sure this is nothing new but my searches haven't come up with anything.
Thanks.
