I just replaced the front drive axle due to the old one being bent on my Lionel Southern Crescent 38607 locomotive. It runs like a champ now.
Problem is, as soon as it goes around my loop and makes it to the terminal track, it completely stops every time and won't move again unless I pick it up and place it somewhere else. It also trips the Z1000 circuit breaker when it does this.
Layout wiring is correct, and this doesn't happen on my other locos.
I attached a photo of where it stops each time.
