I have two ovals of track. The outer oval I want to run TMCC/Legacy stuff and on the inner oval I want to run conventional engines. I have the Legacy base station powered by a 180 watt Powerhouse for the outer track. my question is can I use the same Legacy handheld to control the inner track running conventional trains by using a Powermaster that is powered by a separate 180 watt Powerhouse? Would this then be controlled by setting up the inner track using the TR key on the Legacy remote? Or is none of this possible?
