Built in 1996 by Custom Coasters International, The Underground was the first modern indoor wooden roller coaster.  It remains the world's only totally enclosed wood coaster.

The mine train's track is about 1,000 feet long.  It takes riders past scenes of "Bad Bob" as well as several other audio, visual, and animated gags and scenes.
