There was another thing that I noticed that looked impossible. The turn at the top is extremely tight yet it is only 132ft off the ground, so it is taken with extreme speed. Using some calculations I determined that a train launched at 135MPH would traverse the top of that curve at approximately 119MPH!
I don't see how anyone could survive a turn that sharp at that kind of speed, not to mention the transitions between banking.
Are my calculations correct, and if so what kind of G-forces are we looking at?
