@Bill Sherry posted:I know you understand conductivity because of the 1 ohm resistance you got for the track connections. That is great. If you look at the picture you supplied us of the suspended track you can easily see crud on the top of the rails. You said you already cleaned the wheels, now you need to clean that track up to complete the circuit. Enjoy yourself and have fun. I'm sure this will bring back fond memories from the past. JP
Just a reminder - when cleaning the track (or pretty much anything else related to the train) do NOT use steel wool.
