Anyone had this engine (or the other road names it comes in) stop when going over a Ross switch? The engine dips when going over the frog, causing it to momentarily lose ground contact. I've spent many days figuring this out. I cleaned and polished the switch points where they contact the running rails. Then a flash of inspiration: the front truck has a wire going to the engine frame to help ground connection. The surfaces where this wire is screwed to the front truck and the other end where it screws to the frame, were painted. I removed the paint from these places, polishing the areas where the wire's eyelets contact the truck frame and the engine frame, so now there is clean ground contact. Problem solved. Hope this helps anyone else who has experienced this.
