My rail truck looks great but has never run well. What is the matter with these little guys? the lights come on OK but the motor just has no guts. It crawls along the straights but stalls at the curves. I would dearly love to see it do a full circuit of my track!

My Annie has recently died and I think I might have cooked the motor. It was running on Aristocraft 18V 7 Amp track power. It was running fine and then just stopped. Can you run these locos on that power? Or are they only for use on the less powerful Bachmann power packs?
