I'm putting a perimeter FasTrack on my layout and a tubular inner loop.
They both use a common crossover.
My Question is - if both trains have their own transformer for power on their loops, is that power transferred to the other's track because of the crossover???

If so, how does one isolate those loops so each train operates on its own transformer - make sense???

Most crossovers that I know of have connections inside that bridge power over to the other rails.... so to isolate you would just put Insulating pins in the center rails of the crossover that connect to your inner ring. Or wherever you want the track to be isolated from the other transformer. Remember if you put the pins in the crossover itself.... and you have one transformer off..... the train will stop on the crossover.... probably not a condition you want

T-Man,
Can you give me more specifics on what you stated about running a wire for the connection in my desire to have two trains running over the same Cross-Over???

Thanks,
Mr. Bill

I hope you didn't loose sleep over it.

The X on the bottom of the crossover needs two cuts. One center rail can stay connected but the other is separated from the first. Solder a wire over the connected rail, to join up the cut ends. I explained the outer rails cam stay connected, if both your positive outputs are on the center rail.
