Very cool. I'll have to build one soon!

Taking in a couple of Tobbe's suggestions (and ignoring his worm gear warning), I
came up with a possible drive train. You'll have to add supporting structure. I
used the turntable upside-down, and envision the whole ride suspended from the
base of the turntable (which is on top). You should be able to fully enclose the
drive train in a 10-stud diameter box, so you wouldn't have to put anything below
baseplate level. I'm not sure how well the belt drive will work, but it keeps the
drive train compact, and it's realistic. Also, you can't actually lay a worm gear
box directly on to a motor like I did.

I grease nearly every part of the gear train for shows--specifically to cut down
on the powdered plastic effect. I use "Type 25 silicone compound" from Radio
Shack, but others use other lubricants. Just don't use anything oil-based!
