Thank you that worked! All of the cars are lighted on this set. I tried turning the axles around on the last car and it started running again. Don't quite understand how the axle location changes how electricity would flow through but good to know how to fix it. Thanks again.

I just purchased a used department56 train made by Bachman and all works well until I try and add the last car. When I do that the whole train stops functioning. Can anyone provide guidance on what causes this and how to resolve it?

thanks!
