    Pneumatic tubes use a constantly generated vacuum and air pressure to move objects. It would take forever to pump out a tunnel for a single train.

      No you have two loops of constantly moving air. The train then goes in and out of that tube at stations.

      It’s a fucking shit idea and trains are great. But I remember that and seem to be the only one. No one ever mentions that idea

        Honestly not sure how that would work, but I guess it doesn’t exactly matter. Never heard of it though, maybe you could dig up some article from back then.
