I set up my three rail tubular Lionel track- simple oval. Tested it (before I screwed it down) and everything worked fine so I started screwing the track down to the plywood surface (and cork)-ran the train with 3/4 of the track screwed down and everything still worked great. Screwed down the remaining 1/4 oval of track . . . now it doesn't work.
The circuit breaker on the transformer keeps popping-locomotive has no response whatsoever. I checked and re-checked the track. I even removed the screws holding down that last 1/4 part of the track-still nothin. Took all the train cars and loco off the track-nothin!
The transformer light will stay on for just about 15 seconds with throttle then pops the circuit breaker. It's a brand new MTH Z1000.
Any advice on problems I should look for would be appreciated. I'm NOT an electrician . . . which may be one of my problems.
