NCE Pro 5 AMP DCC. Do all DCC systems do this when switching locos on the one cab control? Using the same cab controller, I set loco1 merrily along it's way, then select another loco (loco2), that may, or may not be running along merrily elsewhere on the layout. As soon as I do anything on the cab, loco2 then sets off with the same speed/direction/settings etc as loco1. I may only wanna just turn the headlight on, on loco2, speed loco2 up a bit, maybe slow it down etc, but if loco 1 was going in reverse at speed 60, then off goes loco2 at that setting too, as soons an anything is touched/selected on the cab. Especially if loco2 is in "reverse" and loco1 was "forward". Do all DCC systems behave like this when selecting another loco from a single cab control?
