I feel like I'm going fucking mental.

I was certain for about a year the idea was pneumatic tubes like in a bank but for trains. Which I though maybe, but probably too much friction.

Then it turned into a bog standard vacuum tunnel that was all over youtube and the Internet before Musk. But everyone acts like that was the original idea.

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.
