Vacuum Maglev

I am rather disappointed that I had never given serious thought to this idea. A maglev train inside a vacuum. Literally no friction to fight against.

It really doesn't sound so expensive as to be unreasonable. I am surprised that no country has had the guts to seriously propose a demonstration project. The Wikipedia page about vactrains does link to a train China is proposing though.

The most likely thing holding it back is safety. Even good technologies suffer some pretty horrible accidents while everyone is learning the ropes. When the technology is a thousand mile per hour train inside a vacuum tube no one wants to have to go through those growing pains.
