Re: Cornering at 270 mph
The first thing came to mind was, I wonder how it corners at 270 mph. Does it lean? Is the track banked? Probably, but it never touches the track/rail.
Then, I thought of a great book, Parallel Lies by Ridley Pearson. A railway suspense involving derails and incorporating computer controlled banking of a high speed train on a flat track (in the last chapter). But the wheels had to touch the track.
Interesting forces in action,
