This actually works. All you have to do is decelerate the train once (because it's spinning with the world while you build it).
And solve the trivial engineering task of reducing all friction and air resistance to zero. Oh, and that of getting on and off the train.
You need energy to decelerate, though.
Just use magnets.
Pls send my Nobel price by mail, I'm not good at speeches.
Fridge magnets are the secret of infinite energy
