Probably rubber tubing as a driveshaft - not uncommon, but it hardens with age, and then often crumbles.

Model airplane fuel-line tubing is a good choice for a replacement, but you'll need to either measure the diameters of both the motor shaft and the worm shaft, or take the loco along if you can find a nearby model airplane shop.

If you don't have a supplier for model airplane stuff, contact me via PM.

Well that was unexpected, would be it be hard to just replace the motor and worm gear with something more effieicient?
