President Musk will never allow it.
Be prepared for cars in tunnels! And poorly functioning cars at snail pace, if that!
High speed rail is amazing! Let’s do it
Elon is in power and has too much money shame him into building hyperloop finally
He never intended to build the Hyperloop. From the start, it was a lie to shut down a proposed project to build a west coast high speed rail line.
Yeah, and it can be defeated with elementary school level math, so anyone in government who agreed to fund it should be brought back to school (though they are probably just more corrupt than stupid).
Everyone in the industry tries to focus on how fast a hyperloop can go, and tries to keep any criticism focused on the engineering challenges (and to be clear, there are many, many engineering and safety challenges).
It should never be discussed as "LA to the Bay in X minutes", it needs to be discussed in terms of passengers per hour.
Given that these vehicles travel very fast, passengers will need to remain seated while the vehicle is in motion. Let's pretend that the occupants of each vehicle are capable of leaving the vehicle with their luggage in under the FAA's targeted evacuation time of 90 seconds (even though luggage makes it take like 10x that). That's 40 loads per hour, and let's be generous and say they fit 40 people, that's 1600 people per hour.
That puts it on par with a lane of car traffic. Maybe you can squeeze some more people in there, or really crack a whip to get people out quick, but you won't be able to get to a fraction of the passengers per hour of high speed rail at ~20,000.
When you actually do calculations with all the other factors, you get ~350 passengers per hour.
Not as long as the cargo railroad companies hold all the power. America needs an alternate timeline with no fascism, sane governance, and making all railroads public.
You wouldn't build high speed rail on cargo lines, anyway. New rail corridors need to be established. The LA-Vegas line is being built along an existing interstate, which solves a lot of right-of-way and land usage issues. That's what you want to do.
That works fine in nowheresville like the Nevada desert. Unfortunately, the bulk of America east of the continental divide is too populated to legally pull that off in any reasonable amount of time.
Much of the cargo lines through much of the country are pretty flat and straight. Tracks and such would have to be upgraded, but doable.
Bigger problem though is my previous mention. They own the lines, so passenger rail is a second-class citizen.
Presumably, those cargo trains still need to run on those routes, but they have no economic incentive to do it fast. You don't want even regular passenger services and cargo on the same line if you can avoid it. Amtrak has a lot of issues because of that. For high speed rail, it could never live up to its name.
America has tons of land. Even without reusing existing interstate corridors, there are some viable new corridors.
Too bad the California high-speed rail project is being threatened by President Musk.
