@Mike Wyatt posted:...ZW-L is integrated into the Trainmaster systems, and using an MTH transformer you would not get that integration. I like my ZW-L, and have (just) figured out how to use it, controlled by my CAB-1. And would they gain if they went ahead now, and sold off the MTH transformer to buy a ZW-L? Or is the ZW-L "just a transformer", and the MTH version would serve just as well once a Legacy or TMCC system is added??If you are running DCS/TMCC/Legacy all in command mode, why are you concerned about controlling the transformers themselves? When running in command mode, they become just a source of power and could be any 18-volt, 10-amp AC transformer, like this one, for $64.
DCC will work with anything that is designed to receive and process a DCC signal. The number of rails has nothing to do with it.
