    These vacuum tube trains are LITERALLY a pipe dream. The largest vacuum chamber on earth takes 8 hours to depressurize using the strongest vacuum generator on earth, and it is only big enough to fit the space shuttle, is underground, encased in feet of concrete, steel, and aluminum.

    It would literally take multiple months to depressurize a (one way) vacuum chamber large enough to reach from NYC->DC. Also it would barely go faster than a regular high speed rail train, plus would be completely out of service any time it needed maintenance
