@BobbyD posted:I may have missed this. Does it do the exact same thing if you pick up the locomotive and rotate it 180 degrees so it is now facing in the opposite direction?
Now that is very interesting.
I did as you suggested, and as led to do by lehighline's comments on right vs left turns.
When running in the other direction, it sparks at all of the outside corners, and finally kicked out the breaker.
However, it is smooth as silk, going thru that inside turn, which I tried, both, forwards and backwards.
So, now to remove the shell and to see what I find.
