Sure. Keeping a chamber from San Francisco to Los Angeles under vacuum should be a cinch.

It will not take as much land as high speed train does we use today and much quicker. It is really a good news. It is faster and cheaper.

But it takes a tremendous amount of energy to pump down a particle accelerator.
It's also a huge expense for all those vacuum pumps and their maintenance.
The largest particle accelerator in the world is only 27 kilometers long.
A train from SF to LA would be at least 600km.

On top of that you'll have to dig a tunnel that long and maintain a viable vacuum tube that long.
Then you'll have the same length of mag-lev track on top of all the other expenses.

How can that possibly be cheaper than a mag-lev above ground?

It might be faster but so would flying everyone in the Concorde. That didn't turn out so well though.
If capitalism promotes innovation and creativity then why aren't scientists and artists the richest people in a capitalist nation?
