China Plans 600 MPH Train To Rival Elon Musk's Hyperloop (shanghaiist.com)

In addition to relaunching the world's fastest bullet train, China is working on developing technology similar to Elon Musk's Hyperloop, which will allow passengers to travel at speeds up to 4,000 km/h (~2,500 mph). The first stage of the company's plan, however, will be to create a network of these "flying trains" operating at 1,000 km/h (~600 mph). Shanghaiist reports: Earlier today, the China Aerospace Science and Industry Corporation (CASIC), one of the nation's major space contractors, announced that it had begun research and development into a new, futuristic type of transport which would operate via supersonic "near ground flight." The system would presumably be similar to that of the Hyperloop, proposed earlier this decade by Elon Musk, in which capsules would fly at ultrafast speeds down reduced-pressure tubes, dramatically reducing travel times. Of course, the CASIC isn't looking to reach speeds of 4,000 km/h right away. The first stage of the company's plan will be to create an intercity network of these "flying trains" operating at 1,000 km/h. In the second phase, this network would be extended and the max speed of the pods increased to 2,000 km/h. Finally, in the third stage, the speed would be boosted all the way up to 4,000 km/h -- five times the speed of civil aviation aircraft today.

      It depends on the train (vendor). There is a railway rolling stock manufacturer based in a mountaineous, banking-centered small european country (let me mention no name). They are highly successful because their trainsets are agile, have a high dispatch reliability of 94-96% and are extremely energy efficient.

      On the other hand, these qualities were achieved by them via designing and building very lightweight trainsets and a series of collisions in Germany, Italy and recently in Austria have shown their crash resistance is more than lacking. Essentially 60 mph (~ 100km/h) there means that you are dead. This vendor will soon supply double-decker electric trainsets to the USA based on a waiver issued by the DoT.

      On the other hand, there are french and canadian vendors, whose multiple-unit trainsets are heavier, less agile and their dispatch reliability is lower, but they are built with both the letters and numbers, as well as the spirit of passive safety (crash resistance) standards kept in mind. There you stand a chance in a 60mph collision, unless you are seated at the very front of the trains. As for the japanese vendors, I have no info or experience, but their high-speed railways are said to be very safe.

      Some people say that since serious accidents happen so rarely, the firstly mentioned vendor has the right mindset. More people can be saved by offering agile, reliable and environmentally friendly electric railway trips as a realistic alternative to the toxically polluting and highly accident prone car use. Should an accident eventually happen after years of rail service, the victims can be financially compensated by using the savings achieved so far.

      At what speed do deaths become common? Even much faster trains like in the recent Philadelphia train derailment, which happened at 102mph, resulted in just eight deaths out of 238 passengers (most people were injured, but like I said, 102mph, not 60mph); similarly the Great Heck train crash in the UK in 2001 involved a train running at 88mph crashing into a freight train at 54mph (effectively a head on collision at 142mph):: 10 deaths, 82 injuries, with 7 people completely unharmed.

      I've quoted this article from 2 years ago before on /. when it comes to Hyperloop, but it is still relevant:

      The biggest issues are speed and scale. The Hyperloop was pitched as faster and cheaper than alternatives like cars and trains, but even small shifts in those numbers can dramatically change how it stacks up. It's easy to imagine safety concerns limiting Hyperloop speeds to just a fraction of its theoretical top speed or right-of-way issues keeping stations far from urban centers. Would we still be excited about the Hyperloop if a 30-minute trek became a three-hour one? What if it cost $60 billion instead the promised $6 billion? After enough setbacks, it might not be worth developing the technology at all. Those deployment details are life-or-death issues for the Hyperloop, but as long as the tests are focused on small-scale loops, it's not clear we'll ever get answers to them.

      SpaceX's latest round of tests doesn't seem likely to change that. The test track is only 5 miles, nowhere near the distance it would take to reach 700 miles per hour. Another test track built by Hyperloop Test Technologies will have the same problem, aiming at a 200mph top speed. For the same reason, these test tracks can’t address the unique safety issues that come with near-supersonic travel.

      Over the Shinkansen's 50-plus year history, carrying over 10 billion passengers, there have been no passenger fatalities due to derailments or collisions,[19] despite frequent earthquakes and typhoons. Injuries and a single fatality have been caused by doors closing on passengers or their belongings; attendants are employed at platforms to prevent such accidents. There have, however, been suicides by passengers jumping both from and in front of moving trains.[20] On 30 June 2015, a passenger committed suicide on board a Shinkansen train by setting himself on fire, killing another passenger and seriously injuring seven other people.[21]

      There have been two derailments of Shinkansen trains in passenger service. The first one occurred during the Chetsu earthquake on 23 October 2004. Eight of ten cars of the Toki No. 325 train on the Jetsu Shinkansen derailed near Nagaoka Station in Nagaoka, Niigata. There were no casualties among the 154 passengers.[22]

      Another derailment happened on 2 March 2013 on the Akita Shinkansen when the Komachi No. 25 train derailed in blizzard conditions in Daisen, Akita. No passengers were injured.[23]
      In the event of an earthquake, an earthquake detection system can bring the train to a stop very quickly. A new anti-derailment device was installed after detailed analysis of the Jetsu derailment.

      They are not going to travel at high speed in a blizzard or hurricaine, and not at all if mafiosos put concrete blocks on the tracks. But there is a lot of safety through high tech, redundancy and humans.

The military mindset might be close, though what is really needed is intelligence, professionalism, empathy, and big bucks for the long haul.

Trains in tunnels are far better protected than other trains and even compared to an aircraft which could be targetted by anti-aircraft missiles as happened in Ukraine a few years ago.

    The other advantage is that failures of the train are likely to be more survivable than aircraft failures since they can carry more weight for protection and a power failure should not mean automatic disaster (although when going 600mph through a tube it clearly is a possibility).

    ... I've been saying that Hyperloop is either a huge scam, or something else I'm still having a hard time to imagine.

    Let's be clear here: The current company that has the most advanced Hyperloop version (Hyperloop One) which is obviously still in very early prototype stages basically stole maglev propulsion system and slapped it into some poorly designed vacuum tunnel to see if it could make whatever Musk scribbled in some napkin. In fact, the first public test Hyperloop One made was just a maglev propulsion system similar to that employed in several other countries that are currently already running actual train test lines (like Japan), or have actual completed train lines (like China and South Korea).

    Almost everything one could point out as Hyperloop prototypes being "successful" can be single handedly attributed to maglev tech. There hasn't been a single significant technological contribution that I know of so far coming from Hyperloop companies, and I still didn't hear a proper explanation on how the heck these companies are planning to build entire tunnels over large stretches of land that would make it any more feasible or more economical over regular train tracks or maglev train tracks.

    The entire idea of Hyperloop puts a whole ton of disadvantages, extra costs, potential problems, among several other things on top of a maglev train to get some theorical speed advantage that's even further into the future and more infeasible than actually making a single working short route from one city to another. It loses flexibility, you need to spend exponentially more (because of the tunnels operating in near vacuum), you are limited to pods of limited sizes, the entire infrastructure becomes far more succeptible to stuff like earthquakes, terrorist attacks, and just plain wear and tear, it'll be mostly point A to B with no stops for efficiency, plus a ton of other stuff to worry about which maglev trains don't have to deal with in their current operational status.

    Yet, for some reason (money laundering, Simpsons monorail style scam, major spec stealing of foreign technology, or who knows what), some European countries plus US and UAE are investing on this. It makes no straight faced sense.

    And I've been saying this in all my comments on the matter: maglev trains are still evolving, getting faster, more robust and better overall - as shown by this article. People joke about it being China and whatnot, but overall, maglev trains are plenty secure.
    Hyperloop might be theoretically faster because it's basically maglev train cars inside a near vacuum tube, but that's only for the theoretical top speeds, which makes investing on it based only on that as much sense as investing on a F1 car prototype for consumers. Just because it theoretically can reach such speeds doesn't mean that it ever will, or even should.

    You wanna see how riding a Hyperloop could potentially be in the future? Go to China, Japan, South Korea or some other country with maglev trains, ride one, but keep seated the entire way and close the blinds. At least if we are to take Musk's designs and Hyperloop One designs seriously. Also imagine being cramped in a far tighter space, and paying a whole lot more for the priviledge - because the costs of building the whole thing up will have to come from somewhere.
