I've got an idea what might happen here.
The ride is sort of a tilt coaster like shown here

However there are 3 round footers. If you have the track strapped to some form of a floor you can create an effect like the floor is collapsing.
The middle footer for the height, going up and down
The side footers to shake the track left and right.
The only issue I can see with this is it not being too realistic. The coaster would have to be held in place until the track is secured. If your crashing through the floor, your going to start rolling backwards straight away.
The only other thing I can think of is the that train gets attached to a piece of track. This piece of track is actually on a roboarm which throws the train about on the track and then places back in the correct position.
I have a feeling we will be seeing some visual/physics trickery on this ride like you experience on Hex.
Im also 100% sure there will be a tunnel if anyone took notice of my post a few pages back.
