A few years ago I build this version of a roller coaster.
It has been on some exibitions since, but it was'nt until now I finally took some useful pictures.
The "cool" thing about the coaster is, that it is build up in two-three hours and can run quite well over a whole weekend, if I use only selected train axles ;-). The Tracks are quite stiff and can be handled well and easy. They are cliped together and fixed with tiles.
the cars are not fixed to the track, which was the main problem... to fast or to slow, fall of or come to a still...
Currently I am trying do do a redesign of the famus "Matt's Rollercoaster" because everybody is asking about a looping.
