back in 2002, on my first basement layout I had Gargraves turnouts. So I was excited to obtain a Ross. I had a similar problem with a double slip switch made by the same company 22.5 degree. It was a beautiful switch but shortly after installation one or more of the rails moved and shorts would happen. I bought it as new at a show so, I had to find a way to stabilize the movable rails. It turned out that the staples(?) used had worked their way loose. The locos would catch or move the rails that would slide through the staples. I had dabbled in O scale (2 rail) and went into my track supply box. Surgery next. I removed the offending rails and replaced several ties with a stronger wood, less porous less worked wood the original staples were useless.
I re fastened the rails with o scale track spikes. It was a tight space but the spikes were thin and long. This remedied the moving shorting rails. Happily the switch was rebuild using the same method.
note the switch I had was an early model production. It seemed more intricate, there wasn’t a diamond plate on mine.
best of luck with yours.
