Anything that can be called "a vacuum" is very very hard to achieve in a large volume.

- jacquesm 3y agoYes. That's why any kind of vacuum solution is likely a non-starter both from a technical and an economical perspective. And the 'obvious' solutions (multiple smaller evacuated chamber that connect as trains pass through) have a whole raft of safety and complexity issues and are going to increase the costs massively.
