Here ya go. This is a video tutorial made by the guy who designed the track in your example image. He says that what he teaches in the video is basically what he does to make his trolley car thing. You just have to expand on what you learn in the video.

well I have watched this by Cannibal but I want to make it bigger and fancier just when it comes to triggering glued items it wacks me up
keep all physics on except one piece , on the glued item, and trigger the piece with no physics onOriginally Posted by BlueRambo7
Well is it possible to have objects (physics on) in each other, glued and not break apart?Originally Posted by 420
Thats why you need the one non-physics object and a trigger to activate physics on it.Originally Posted by BlueRambo7
Yes, when physics objects are past the point of touching, their boundaries overlap, they will try to force themselves apart. That is unless you have them glued to one another. IE: If you have 5 boards overlap inside of 1 board, you must glue that 1 board to all 5, and if those 5 boards overlap each other, you must glue each to the other.Originally Posted by BlueRambo7
Yes, that looks completely do-able. Although I don't quite know what you mean by applys brake. Does the platform or the rider apply the brake?
well the platform will be sliding down at a 45degree angle and the beams above will be parallel with the platform the bike is sitting on
