I have seen videos of the esu mobile contoller two able to controll mth ps2/3 in dcc on 3 rail track. they only show a test track of one long straight track set up though. is this set up really possible on a real 3 rail track layout especially with reversing loops? I was just toying with the idea of trying to run my mth engines using the esu command system. I know the ISU proto throttle will work with the esu command station. the ISU proto throttle looks so cool and prototipical to use. I thought maybe using mth o scale engines would be even better given thier size. not sure just how well the 3.0 electronics with built in dcc would run vrs. a real dcc decoder such as esu o scale decoders. like I said I am just toying with the idea. anyone trying this or have any thoughts about this. feel free to comment. thanks.
