The fact that the hyperloop is not a train is by far its most important feature.

We have reasonable cost estimates for trains, with a new unproven technology, you can make any cost estimates you want.

But its all a shell game, the hyperloop has every constraint a train does (and more!), and will inevitably, at the very least be exactly as expensive.

This is an old game, I'm sure everyone remembers The Simpson's monorail episode.

I'm not quite sure it's possible for a vacuum tube to cost less than some steel for a train track.

I guess it could be cheaper to build it under a city (tunnel needs to be smaller), but anywhere else... highly doubt it.

Plus, you know, trains are faster, more comfortable, have sleeper cabins, quieter, easier to stop in an emergency, and even have windows!

Hyperloop is basically Musk's dislike for sharing space with other people. Some of them might even be murderers, to put it in his words.
