@Richie C. posted:Maybe I'm missing something but, assuming you are powering the entire layout as one loop, I'm not sure why you can't run trains in each room individually just by closing the switches and run both rooms as one big loop by keeping them open ?
That would work if both engines go about the same speed for a given throttle setting and they are set to go only forward. But if the engines go vastly different speeds for a given throttle setting, you could have one traveling at a moderate speed, while the other goes too fast to stay on the track.
