Its very easy:
Use a Gerstlauer Bobsled track and shape the layout (
with banked turn of the track and not the train)
-Center of Raily (y) = 2m
-Save park and import the last track
-tilt the track, until one rail reaches ~the middle of the base-track (the first track) -> didnt do that on my version, and thats why the tracks looks chaotic.
-Save park and import the last track
-tilt the imported track by additional 4??
-repeat.
By arount 25 tracks, you should have reached the half-pipe shape.
-Import your base track (the first track) and now you need to add the banking of the cars.
