Maglev Train Exceeds 600km/h For World Record

nojayuk writes: An experimental Japanese magnetic levitation train has reached a speed of 603 km/h, breaking the world speed record the same train set last week of 590 km/h. "Central Japan Railway (JR Central), which owns the trains, wants to introduce the service between Tokyo and the central city of Nagoya by 2027. The 280km journey would take only about 40 minutes, less than half the current time. However, passengers will not get to experience the maglev's record-breaking speeds because the company said its trains will operate at a maximum of 505km/h. In comparison, the fastest operating speed of a Japanese shinkansen, or "bullet train" is is 320km/h. ... Construction costs are estimated at nearly $100bn (£67bn) just for the stretch to Nagoya, with more than 80% of the route expected to go through costly tunnels, AFP news agency reports."

    Not if you count the time getting through security. For me, this is one of the biggest comforts of riding a train. I use it for short city to city trips. Show up 20 minutes before scheduled departure to make sure you aren't late, walk on, walk off. Most train stations are in the middle of the city while airports tend to be on the edge of the city, which, depending on where you are going, can often add even more travel time to travelling by air. Also, sometimes minimal travel time isn't the biggest concern.

      Then every car (and the tunnel itself!) needs to be a pressure vessel and you need oxygen masks if there is a leak. Plus you have to turn every station into an airlock. Depressurizing the tunnel is a lot of extra work.

      It might be easier (although not much more sane) to have two large ventilation systems for the tunnel. One working at high negative pressure (near vacuum), and the other working at a high positive pressure. The vents would be shutters that could be opened and closed rapidly, so you're always pulling air from the front of the train and introducing it behind the train. Basically you would always have a strong tail wind, reducing the heating effects of compressing that much air. The energy required to move the air would be substantial though, and it might not make sense. The high speed shutter system would be relatively complex too, and making it reliable would be a challenge.

    Trains don't have security theater yet because of the lower perceived potential impact - you can't crash a train into something, for example. This is, of course, an display of lack of imagination. Living near NYC, I am all too familiar with a multitude of bridge and tunnel crossings. Damaging a train - even a local subway train, not a commuter or long-distance route - in the middle of any one of those would cause serious headaches, if not major consequential damage. The real point is that an ultra-speed line operating the Boston-NYC-Washington corridor, or any other section of the major city routes, would become a much more attractive target because of (1) its very newness and shiny-ness, and (2) the higher possibility of doing consequential damage by damaging a train at higher speed. One must assume, then, that some degree of security theater will be imposed on the new rail system.

    One must also assume that since the new tracks will have to be totally new, they will have an excuse not to follow existing tracks into the old center city stations along highly expensive rights-of-way, but will instead stop at new stations outside of cities . . . maybe at airports, to take advantage of at least *some* infrastructure. This would be OK if there were better local connections, except in the US many airports have no connections to their cities; the three New York City area airports, for example, despite being in one of the best mass transit centers in the country, were never fully connected to the existing local commuter train lines. And bus service is laughable.

    That assumes the entire cost scales equally, but I suspect the major cost is the development of the technology and the building of the train itself, the track and associated infrastructure is probably a lot less.

    Something like this would be amazing to have in the Northeast Corridor - heck, we're spending $117 billion just to increase the speed there to 350km/h. At 500km/h it would take an hour to get to New York, which would be just as fast as flying, without the insanity and the hassle.
