Dunno why I bothered to update this old thing, but I did. It works again now.

Minor track tweaks (collision-proofing, redundant part removal)

Corners and slopes are now smoother, allowing for slightly faster speeds. Many thanks to Neotician for the suggestion! (check out his stuff: http://forums.keenswh.com/post/my-wheel-based-concepts-will-be-posting-continuously-6866433?pid=1282599457 )

Rebuilt the tram and improved its aesthetics. It's now a little more rugged and works slightly better than the old one.
