Gentlemen,
FasTrack switches have a lot of plastic in them, that causes the problems that
he is having, in reality this is why I had to engineer my FasTrack Layout with
the old 711 and early 072 Lionel tubular switches. There are just some engines and Trackmobiles that the FasTrack switches will not accommodate. The reality is FasTrack switches were engineered for modern trains, not Trackmobiles or Tin Plate Trains. There are only 2 kinds of O Gauge switches that I know of that accommodate every different kind of O Gauge engine, along with Trackmobile and small independent Car & Truck type motorized equipment, when running at normal to slow speed. The original low voltage, K-Line SuperSnap Switches, which are now the RMT SuperSnap switches, and the old 711/072 Lionel tubular. Down thru the years, I have tested and run just about every different companies O guage switches, some we bought and resold, others were borrowed. It is not uncommon for FasTrack switches to stall TrackMobiles, it is simply the engineering design of the FasTrack switches. To much plastic and not enough metal for contacts.
