This is Hyperloop test site in Mojave desert (next to Vegas I think) visit by a newly formed Future Forward Party and the two claimed that apart of its MAGLEV units (the 'Track') rolling stocks and so many things 'Can be made ENTIRELY by Thai industrial sectors. What i've known today is that the Loop is an evolution of previous Maglev that exists for decades and merely past prototype stage (so far only Shanghai has one).

Unless you account for the costs to build the thing. And account for the costs of keeping a thousand mile plus long tube in a near vacuum state, plus the maintenance costs for said tube. I mean, if you can develop the technology, great, because it's the same tech you need for an orbital launch cannon, which is a practical application, but a hyperloop won't replace high speed trains anytime soon.

Yup. The issue with projects like this is it is a MASSIVE initial investment to get it built in the first place. It takes so much inertia to get going that the short term and even medium term benefits aren't worth using it to replace other forms of transit.
Its kinda like how, in theory, we could have a high speed rail allowing people to commute between San Fransisco and LA. The issue is even if you created such a line instantaneously, you wouldn't have many customers at first because nobody currently commutes between San Fransisco and LA, and anybody who travels between them is currently using other forms of transport. Its effectively a non-existent market.
So such an endeavor would have to be propped up for years before you actually had any profit to keep it going on its own.

Most countries which want to use railways already have good conventional rail networks which get people where they need to go in a suitable amount of time.
If you've got to go farther, and want to go faster, it makes more sense to develop electrically powered short and medium-range air transport, like Norway is doing.
Part of me thinks the technology is interesting, and could have particular uses, the other part thinks it's just impossible to build something like this on the scale of conventional rail, both in practical and economic sense.

Then again people might have thought same about regular trains before...
Maybe hyperloop starts to get more traction when current type of airplanes become unusable/too expensive.
While this is really cool. I just don't see this providing anything high and above high speed rail. High speed rail is already really fast. I'm sure some placed will build some ^ as pointed out above.
It's more about the prestige than anything else.

Hyperloop would potentially allow trip that's distance about same to Finland to Japan in about 6 hours. With Japanese bullet trains more like full day. "Bit" different in speed.
Now sure now airplanes do that work. How long before airplanes goes out of viability?
Would you really want to get into an enclosed pipe, with parts of it many miles from anywhere? If there is a major breakdown, what do the emergency services do?
The Channel Tunnel from England to France has 2 parallel train tunnels, with a spare service tunnel in-between. If there is a problem, they can get services in down one of the two that are not blocked.
With this, they'll need access hatches spaced along the pipe, and have to fill in the vacuum before anyone can get in.
The idea is good, but are a lot of potential problems to sort out. I am sure they'll have most of it done, but I haven't seen any mention of it.

I think we are more likely to see electric planes take up that kind of long distance travel.
Alternatively, perhaps the coming utopia of AI powered 3-day working week will allow us the spare time to take a train trip to Japan and enjoy it taking several days. I bet you see a lot of different countries and scenery on such a trip!
A friend of mine travelled from Europe to Japan by train, along the Trans-Siberian Railroad to Vladivostok. the photos got more and more bleak as the journey went on, and the destination looked exactly what you'd expect a neglected ex-Soviet naval base in the middle of nowhere to look.

That is about 800 mph. That is not unbelievable. It's much faster than a plane even (they tend to cruise at about 600 mph) it's just that a 4500 mile vacum sealed tube would probably cost 50 billion dollars and take 10 years to construct. With that you could build a whole fleet of electric planes in probably 2-3 years and fly anywhere in the world. It would just take a little longer. It's realistic to assume electric planes will likely be able to to reach about half that speed.

the link Skinnerreal posted mentions the problem of lateral acceleration - "shoogling", to you and me. With a system in California, I would imagine that tectonic activity would be an issue, and it would be even more so for a transcontinental system - how do you adjust for even normal tectonic movement, let a lone earthquakes distorting the tube (and if it breaks the tube, that would be catastrophic).
Assuming this thing is moving at 800mph, it'll take 12 seconds and 1.3 miles to come to a halt at a deceleration of 3g.

Given that the Virgin test site in Mojave tests 'passenger pod'. I can't really imagine that it can perform HST functions of Freight. (while HST today has also been applied to freight service... the Chunnel did operate freight trains as well).
No sorry I don't know what that is. I'm from England.
You've got better ones than we do.
But then we gutted our massive rail system and offered in up it sacrifice to the diesel truck gods.
But I never had a single trip from Boston to Baltimore that wasn't delayed an hour or two en-route. Waiting around for the departure time in Boston was always a blast too, since the building was in a bad enough state that the train exhaust essentially vented itself from the tunnel through the building to the outside.

Only an hour or two delay AND a building?!?!
Jeez you guys are living the high life.
I'm use to constant cancellations and very low crumbling platforms with a meter gap between it and the train with a pool of puke and human faeces at one end and druggies at the other.
Some parts of our network (southern rail...) are terrible. I believe the US has the same issue. Many years of under development and failure to maintain and some parts are getting to the point where it will cost more to repair than just wholesale scrap.

I've been meaning to post this video. I found it interesting and shared a few parallels between it and the hyperloop technology discussions here.
It points out that sometimes it's easier to simply hone current technologies, rather than create something completely new. Why build a hyperloop when bullet trains could potential reach new levels of efficiency? Of course, you could also argue that current trains have already reached the peak of their technological progress.

One of my colleagues went to a conference in China and went on the electromagnetic suspension train from the airport to the city. It's either Beijing or Shanghai.
He said it was very fast but the altitude control wasn't perfect so occasionally it gave a kind of swoop and judder which was quite disconcerting.
