MR_P posted:Nope, but I am running it on O42 MTH track and for that size a loco E-8, it's a pretty tight turn...
Track is new as well, and I've not have any other problems , just this PS-1 engine and it's the only 1 I have.
I will check the wires from the pickups as I think GGG might have meant ?
I had a Williams Locomotive that did the same thing, It was a loose wire inside of the engine and the loco would sputter and jump on curves. Easy fix...
