I’d imagine this would be cheaper than air travel. Also air travel is annoying and a hassle if you’re just trying to go a few states over. Like DC to Philly or NY. Also if you’re traveling for business it’s probably easier to get work done on a train than a plane.Why do we need this when we have planes a cars everywhere? Don't get using old technology just because. Now if we are putting in those warp trains that no one has yet sure....
