Hi John.
On my SuperSnap layout I have had two places where shorts have appeared:
1. Where the SS track mates up with O gauge tubular track, the metal contact under the center rail of the SS track was barely contacting the black tie of the tubular track. I forgot to remove that SS contact. The result was a low grade short that was a challenge to track down. If you have tubular and SS track you might want to check those connections. I use track pins on all my connections.
2. Sometimes the switches developed a short. This seemed to occur after a lot of use. I think the SS switch which was screwed down became a little loose after use. There must be something in some of the SS switches that can cause a short if the switch becomes a little loose. Once I screwed the switch down again and there was no short and then everything was fine. This happened a few times with several of the switches.
