HELP! HO scale red rock express

[Mamachloster]

Purchased off EBay last year and worked great. Set it up yesterday and it seems like it is dragging the back wheels on the powered engine car. Could they be locked up somehow? Any advice would be greatly appreciated. I have no clue what I'm doing but have VERY sad kids who have looked forward to the train since last Christmas.

Sounds like the drive shaft to the rear truck may have come loose. You can remove the body to check and put it back in place if it has.
