    Works for me. But it'd be a bitch if a terrorist ever managed to get in there.

      but that's what brakes are for.

        •  Nearly instantaneous tube REpressurization... (1+ / 0-)

          can be achieved in an emergency, and is far less likely to be deadly than sudden DEpressurization at civilian flight altitude, and probably no more common.

            a terrorist device might cause damage, not just pressure loss. Consider the subway bombings. Now think of that with more passengers on a larger train going much faster. The train could rip itself to shreds as it twists and turns inside the tube,  digging into the walls at several hundred miles per hour. Even if it's electrically powered, grinding up all that combustible material, like aluminum, at high temperatures could cause a fire... which could turn into a thermobaric bomb when you suddenly dump oxygen into the mix.

            Not saying it's not a good idea, just saying it has some risks. It'll have to be treated more as an airliner than as a subway, which means more time, more money, and I doubt it would be competitive with air travel or regular trains.
