For this one, I'm going to exerpt from the readme.

"A remake of my favorite MTM1 track, King of the Hill. Original track design by David Glasscock from TRI. I changed the terrain and textures from the old track. Some well placed bumps and dips give this track a new twist. If you run off the edge there are places where you can get back up easily. Some new things to look for are several types of trees and a new high speed passenger train, The American Flyer."

Well said! I will add, however, that this track is a blast in multiplayer.
