China Plans 600 MPH Train To Rival Elon Musk's Hyperloop (shanghaiist.com) 159

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.

        Your nuts. A train going 60mph (I'm assuming it's not going through some tube) that crashes is going to be survivable for nearly everyone on board. A train going 600mph through a tube (partial vacuum no less) that crashes (and I assume that means some sort of derailment) is going to be a disaster.

        60mph train crashes have happened many times in history, but in the last 100 years or so very few have resulted in the majority of passengers being killed or seriously injured.

          A train derailment results in cars sliding across the ground and (relatively) slowly piling up. The train and ground are basically parallel.

          The head on collision is a perpendicular impact for the lead cars, but much more like a derailment for the following.

          There's even less to run into in a low-pressure, sealed tube. Not even much air. I suppose there are other trains running through the same tube, but tube traffic control is much simpler than air traffic control .

        Wheeled trains can already reach those speeds, the problem is noise. Current high speed trains in Japan run under their rated maximum to keep noise down, especially when leaving tunnels where the air pressure creates a boom.

        Japan has been trying various things to deal with the problem, and is going to have its ultra high speed maglev line 90% tunnel with very long braking areas to dissipate the pressure wave.

        Maybe they don't care so much about the noise in China, perhaps the tracks are further from populate

          • by Shotgun ( 30919 )

            And this is probably how we will see the technology really build out. High speed trains will be slowly covered in tunnels. Then the operators will start to evacuate the tunnels so they can increase the speed. They'll pressurize the cars for passenger comfort, which will allow a higher level of vacuum. They'll basically sneak up on the hyper loop.

    • Overly fast trains are too easy to sabotage anyhow. Would you rather be in a train crashing at 600mph or 60mph?

      These trains are designed to compete with planes, not other trains. However, even then they would be a lot more difficult to sabotage than today's high speed trains which run at 1-200mph, not 60 mph, above ground on open tracks which are accessible by just about anyone at any time. 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.

        I like how you think. It addresses some of the worst problems I saw when trying to use the train in the US. The whole train has to stop at every podunk station along the rail.

        Instead, passengers getting off at the next station move to the rear car. When near, it disconnects and takes a side track into the station. Another car, loaded and ready, uses it's battery pack to accelerate and catch the main train that never stopped. When it catches up, it connects. People not getting off at the next stop move

    • Next time, fact check instead of spreading FUD. The bullet train in Japan is extremely safe. Here is the reality.

      https://en.wikipedia.org/wiki/... [wikipedia.org]
      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.
      -snip-
      I believe the safety of these trains are in part due to the absolute professionalism of all people involved with its operation.

      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.

      I am not sure this level of professionalism is possible in the U.S. or especially China, considering the current state of their trains, unless a totally new kind of cadre is created. The military mindset might be close, though what is really needed is intelligence, professionalism, empathy, and big bucks for the long haul.

      The U.S., China and other countries the size of California and up will gain amazing returns from these trains. The only downsides of which I am aware (and they are not downsides to me) are that they drive down the price of air tickets and also get you used to such comfort that you wonder why you stick yourself in a flying can with miniscule leg room.

So you want all the pods making that exact trip to assemble at given times, but to avoid waiting, you'd be told to leave home at particular times. S

    China Plans 600 MPH Train To Rival Elon Musk's Hyperloop

    You mean the Hyperloop that does not exist?

    And will never exist. Sorry, but expecting to maintain near vacuum in 350 miles of 3-meter diameter tubing is not going to happen. Temperature induced contraction and expansion, earthquakes, vandalism, and sabotage. There're your problems.

    And when it does fail, what happens? The entire system goes down as it loses vacuum. Assuming you could get someone to whatever remote location is required in a timely manner to repair the fault, how long will it take to put the whole system under vacuum again? All 350 miles of it? Assuming you weren't pulped when your carriage travelling at 1200kph suddenly went from operating in a vacuum to operating at standard PSI.

    • by Rolgar ( 556636 )

      If you put a small vacuum machine (powered by covering the tube with solar panels, which also power your propulsion) on every 10' of track, I imagine they could probably get most of the vacuum restored within 10-30 minutes. And you probably don't even need a perfect vacuum. Just cutting the air in the tube by 80-90% would be enough to severely reduce air resistance without putting too much pressure on the tube.

    ... 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.
