Now I'm going to have to look closer at mine. I have so many engines, I never got around to converting mine to 2 rail. I have run them as is and they were fine. I did order P&D fixed pilots, just never got around to mounting them.
I prefer modern stuff so these have sat around waiting for another rainy day.
Talk about wheelies? I had to think of this engine that I bought that's a shelf queen. She can't go around the layout even once without jumping the rails.
This is someone's attempt at a 2 rail conversion that doesn't work for me. It is another brand (L) that the electronics, also don't get along with my stuff. So it sits on the shelf. The wheel profile is very different (round tire edges) and the trucks swing wildly when the power is applied so that they jump the rails. Someone added screws to limit their travel?
