Just got our Wonderland Flyer set running - 4-6-0 locomotive is slipping now. Wheels are not slipping, it seems to be internal. It will move forward and back, but I can hear the motor running faster than the drive wheels. Is there some maintenance I can do?

I have lost the red cable that goes to the track, and of course we lost the track connector as wewll. To make it work for Christmas I plan to build a cable and some alligator clips on the track. But I need a diagram or a simple explanation. Don't want to get the wires crossed!!

Radioshack should have what appears to be a 1/8" plug.
