I added two brand new switches to my layout, Lionel 5021 manual switches, to make a turnaround.
Every time the engine goes over one of the new switches, it shorts out and trips the breaker in the transformer.
Once the engine is pushed off the switch, it operates just fine. It has no problems on any of the old switches on the track, which are just older 5021's and 5022's. Just the new ones.
Any ideas? I can't really see anything different about the new switches.
