Funny thing, decades ago when I still subscribed to Popular Mechanics and Scientific American, I fantasized about subways in vacuum tunnels and even long distance trains that would “drop” into straight tunnels that ended in distant continents – gravity doing the work, like pendulums.

My solution starts with a gravity assist. Yours needs antigravity! .
