Well, my Southern Belle runs again, and again, thank you for your help.  The problem was a badly connected red wire to the rails; it did not stay in place.

Thank you so much for your help, il will try to double check things.
But i was wondering, is it normal, when you have the locomotive in the palm of your hand, that the wheels and rods do not turn?

Hello everyone! I am the new owner of a Bachmann Southern Belle set.  You can look at its maiden voyage sunday here

Today, i put the set on my countertop, every link is ok.  Nothing moves. The litte locomotive itself seems to have a problem, the little connecting rods dont seem to work at all, the wheels dont move.

Than you in advance for your help!
