Here's an idea using bobsled track:
----------------------------------------
NORMAL TRACK
????????? ????????? ????????? ????????? ????????? ????????? ????????? ????????? ????????? ????????? ????????? BOBSLED TRACK|BRAKES|NORMAL TRACK
So it can just have like a 4 foot jump(maybe smaller), then land on bobsled WIDE track that is slipper just a bit under the normal track to insure a safe landing, then brakes to slow it down, then the coaster continues the course. That might be the easiest thing if the wheels would work.
EDIT:I drew a quick picture of how the track would look, only I tilted it so you can see what it looks like. NOTE:The image is VERY sloppy:-p
