Our clubs Lionel layout has an outer loop and an inner loop. Recently four turnouts were purchased so we could run a train from the outer and inner loop. The turnout layout has each pair of turnouts hooked together with isolating pins on all three tracks between the turnouts. There are two transformers (CW40 or 80) one for each loop. Their power cords are coming off of the same outlet. The engine switch is in the forward only position.
The problem is when the engine crosses over onto the other turnout, the engine stops and the transformers indicate a short (green light on both transformers are blinking). I'm assuming that the back truck and front truck on the engine are "common" so when the front truck goes over onto the other turnout each truck is on it's separate power supply or transformer. Should this make any difference when it's AC?
I have another question. Should the two transformers be interconnected by a lead going from the common of transformer 1 to transformer 2?
It's been half a year, but if you are still having trouble-- or someone else is-- then here you go... Clean the track and check to see if your track is dead. If your switches have not been wired for constant voltage do so now. If you still have trouble then let me know.
