Japanese Train Sets A Speed Record Of 581 kph

Azuma writes "Last night, on December 2, a high-speed Japanese train set a new record of 581 kph, breaking its own previous record. The new Maglev high speed had real passengers on board this time. They proved that the distance between Osaka and Tokyo can be covered in one hour's time. However, we wouldn't see real trains for a while now since the cost is prohibitively expensive at this time. However, they expect that the cost would come down over the next 20 years. This seems to be the future of transportation, at least in Japan. Here is a detailed article from The Japan Times."

    It's hard(er) for a mag-lev train to derail sincehte 'wheels' wrap around the track. For it to derail it would have to rip the track apart. Not saying it's not possible but it's less likely to happen than on conventional trains.

      The degree minute thing probably came from the Sumerians who actually used base 60 for their counting systems. It is postulated that they regularly traded with another race and so came up with a base which could be used equally to translate from their 'old' units and those of their fellow traders.

      Base 60 makes it easy to divide values by common fractions, a half, a third, a fourth, a fifth, a sixth. Hence 60 seconds in a minute, 60 minutes in an degree and 6 x 60 degrees in a circle. The sumerians also gave us positional notation (ie. that the same symbol in different positions in a number means a difference value) which is where our hundreds, tens and units comes from. Some even believe that they invented 0 (in which case it was lost for some thousands of years afterwards) and it's shape comes from drawing () with a stylus in a clay tablet (their write once memory).

      Too bad most places don't invest in more trains. However, investment usually implies a return, and most train companies lose money. The more captalistic a country is, the worse this becomes... note in the article " Central Japan Railway Co. (JR Tokai) and the government-affiliated Railway Technical Research Institute." that it's a state sponsored initiative getting these things going.

      The French TGV is one good example of a system that works, but it's not easy to replicate economically in a country like the UK where there is public outcry at any possible addition of rail links or something close to where they live (and population density is three times higher than France, so routing around people isn't as easy). The Eurostar now has high speed track for part of the link in the UK, shaving 20 minutes off total journey time, but the route is incredibly inefficient and could have been much more direct. Also, it was way off schedule!

      The US gave up on trains long ago. Flights and cars are all there is, Amtrak is a joke. Ironic that the rail revolution made the US what it is today, and it has to be the major economy that has turned its back on rail the most. High speed services coast to coast would undoubtedly be too expensive though. I think there must be a magic ratio between average distance travelled by passengers, total country size, train running cost and so on which the TGV manages to get close to. The TGV rocks.

    This is obviously very impressive. Maglev trains are very expensive (especially the track), but they reach enormous speeds. It gets even better if you let them run in a depressurised tunnel, allowing them to reach speeds of several thousand kilometers per hour. Of course, that costs lots of extra moolah, but its an upgrade possibility once maglevs have become more commonplace.

    Concerning the question of why other countries don't have trains as cool as Japan - well, several reasons. The US just aren't interested. Appearantly, the American Way means having two cars per family and getting stuck in a traffic jam at least once a week. Besides, there are geographical concerns. America, as well as my home country (Germany) are definitely two-dimensional, rather than a linear strip of settlement like Japan, meaning that one requires a grid of synchronised train lines. Trust me, that's hard.

    Also, for the US there's the problem of population density. Sure, in the cities, public transport has customers. But in the rural regions, there isn't enough demand to make narrow-interval trains profitable. And the broader the intervals (say, twice a day?) the lower the interest. After all, why wait two hours for the next train, when you can jump in your car now?

    Actually, the one in Shanghai, PRC, has been 'deployed'.

    but also in the cost to power the trains.

    Of course the maintenance on regular trains is a wee bit higher - unless you think replacing those big steel wheels and the brake systems due to wear and tear is something that's cheap.

    Once you have maglev, you are restricted to long-distance trips because there is no maglev track feature similar to a "switch"

    Really ? So what, exactly, do you call this thing then ?
    http://www.transrapid.de/en/medien/praesentatio n/1 1.html

    Given the lack of developable land in Japan, where do they expect to put the tracks, since they would have to serve the existing stations which feed regional, metro, and local rail? Would they replace the existing bullet trains?

    Maglevs can easily operate on levitated tracks above existing tracks if so needed. Of course replacement would be a better option, but disrupting commuters is likely not a viable option, so alternative transportation would have to be introduced for as long as construction would last.

    High-speed rail demands extremely precise rail alignment and a continuous maintenance program

    Rail, yes. But this is maglev. Rail doesn't give you an inch leeway. Maglev does. Maglev gives you way -more- than an inch leeway. Slight disruption of the guideways won't be much of a disaster.

    Speaking of which - maglevs can't derail. You don't happen to know the -main- cause of rail incidents is, would you ?

    But if the segment does get destroyed, you install a new segment. Yes, it'll be more than a bit of steel and welding, depending on the maglev construction (i.e. linear motor in carriage, or linear motor in segments). But either which would not take much longer than replacing a segment of steel rail.

    Rail trains can even run efficiently at low speeds, as opposed to maglev

    Moot point. These things are meant to go fast, not slow.
    When do regular trains ever go slow ?
    1. When going through neighborhoods to prevent too much noise from being generated.
    - Maglevs are MUCH more silent, not an issue
    2. When leaving a station
    - Maglevs accellerate much faster, not an issue*
    3. When entering a station
    - Maglevs decellerate much faster, not an issue*

    * where they do go too slow, no worries - the levitation is generally not handled the same way, but rather by batteries in the carriages. They can levitate just fine without external power. Should they run out of internal power as wel, they generally 'land' on plain rubber wheels, and can be collected by another maglev.

    There is also the environmental/health impact of intense, uncontained magnetic fields.

    You're talking about te type of system where the linear induction motor is inside the track. The track segments get switched by the passing of the train. The magnetic field is directed upwards and does not extend a lobe of more than 10 meters at best.
    Which means that you have to be standing on the track, when the train passes over it, to be affected. I *think* you would have other worries at such a time :P
    Even if you think a bird may be affected, though, a track section's length is up to 62 meters in length. Even if travelling at 'only' 400km/h, that's passed in 1.79 seconds, with the length of the segment decreasing over that time as the train passes over.
    Inside the train the magnetic field is negligable - less than a CRT monitor.
