Why go underground (expensive 3rd dimension down) when we have the whole 3rd dimension up almost unused? The freight can be trucked by large Zeppelins for example (and electric at that with the most of the energy generated by the solar panels covering the upper surface of the Zeppelin https://news.ycombinator.com/item?id=38017937 ). The issues are pure engineering ones. These freight Zeppelins can be fully automated,…
A train car carries about a kiloton of cargo. How many zeppelins would that take? Edit: Actually, I can't count. Only a few hundred thousand pounds. That's still probably a bunch of zeppelinworths though.

Elon Musk said from the outset that he was not gonna build it, he thought the idea was good and published a whitepaper on it which basically started the conversation. He also talks about a supersonic electrical passenger jet from time to time, but he says he don't have the time to do that either.
Perhaps we should apply a bit more of a critical standard to Elon's various statements: https://motherfrunker.ca/fsd/

That sounds like railroads but worse. What's the advantage? Tunneling is incredibly expensive to do, yet you're proposing it in a situation where it'd need enough coverage so as to ban large freight transport over roads.
I’m not arguing with you here but it would be interesting to know what about tunnelling is fundamentally expensive. Things I can think of: it is slow, so you burn through a lot of wages. To compare with road building the only major road I can think of, built in my lifetime, was the M40. It is 90 miles long and took 4 years to build but I don’t know what the cost was. The channel tunnel is much smaller than a freeway…

#174There is a world where we dig tunnels under federal highways, and stick freight trucks down there. They'd run on a monorail, at 120+ mph. Surface vehicles would be dramatically limited in terms of height, width, and length. Maybe people buses could go down there? In my imagination these tunnels are, like, 200' down. Like mole people.
Why do people keep trying to invent more expensive, less traffic dense railroads. Did they stop teaching arithmetic in school?

Its super common in Australia for railways to shut down due to warping of the rails from heat.

You have, once again, described an expensive and bad train.
I still haven't seen the math to prove ground effect aircraft are less efficient than cargo ships, but I suppose it's true or it would've been done already.

Contrarian take, but tons of truck traffic on interstate highways makes driving far more fun (as long as there isn't road maintenance or undue stoppage). I'm actually looking forward to future me being able to ride my motorcycle around a freight-train's worth of semi-automated cargo-haulers on interstates that are mostly devoid of vacationing families.

#179Robert Goddard designed a vacuum train in the 1910s, why did Elon think it was going to work a century later?
