Duck Duck Go gives results on this.
I think you have to play around with the entry I usually type in D.U.M.B. I’ve found a lot of people talking about the sub US system and a Maglev system that goes at an insane speed.
What if the technology existed in the 1930s/40s to build a machine that could bore and melt through a rock?
What if that rock was at a consistent depth around the earth, with no geological changes?
What if that rock was far below the water table?
What if the introduction of maglev helped to sweep the system of its stale air and other ( unknown processes) helped with ventilation energy and light?
For doubters here’s some timelines to consider.
When the London underground system was put in place it was bricked out and took years to build
Brunel etc started playing with sealed air tunnel building systems.
By 1920 tunnels under rivers in London, New York and Liverpool seemed to be at the extreme up to 1 mile.
1990 Channel Tunnel 25 miles of air conditioned tunnel just below the surface.
CERN was bored out of rock relatively quickly and we now know that there are a vast array of machines that can move at a pace back filling and a tunnel with cylinders as they bore.
There are a couple of these machines in the UK ( German made) that were used for cross rail in London and have been moved on to HS2.
All of the above is done at or just below the surface where they deal with soil, sand, chalk, sandstone and hard stone changes every few hundred metres.
We have heard about Denver and the surrounding area so we know that capabilities are advanced.
10 years ago Musk indicated that he wanted to build a Maglev link between LA and San Francisco and the world thought he was crazy. Now he’s set up a development to build boring machines.
