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."

The relationship between the railroads and goverment was cordial hostility at best, which dates from the trustbuster era and the way the goverment nationalized the railroads during WWI. Even if what you say was true, the automotive industry failed signally, as they didn't replace the railroads for long distance travel, airlines did. As I said before, what the automotive industry killed was the intraurban railroads (trolleys), which were a very different kettle of fish from the big national railroads. *Don't* confuse the two.

      In fact, most of the large railroads were relieved to be rid of passenger traffic, as it barely broke even, and generally lost money. They maintained it as long as they did because passenger trains served to keep the railroad name in the public eye, and in hope that 'brand recognition' would lead them to choose that road for freight shipment.

      The airlines easily bested the railroads after WWII because of the the condition of the railroads. Between the Great Depression and WWII very little new equipment was purchased. During WWII the massive amounts of traffic served to wear out what equipment there was. As a result, when it came time to compete, the railroads were in a hole because of the amounts of capital investment required to repair the damage, while airlines needed only buy equipment.

      That highlights a key difference that continues to handicap railroads. Airports and seaports are generally built by goverments (local/state/federal) who hope to recoup construction costs via a higher tax base. Only operations costs are paid for by user fees, (every time you fly, some of the money you paid goes to the airport you depart from and arrive at). Highways are built and maintained the same way. Thus shipping lines, truck lines, and airlines only need pay for their operating equipment, and some overhead. Their capital costs are far lower than that of the railroads. OTOH, railroads own and maintain their own physical plant, as well as their own operating equipment, thus vastly increasing their capital costs.

      It's in the books. Don't make me cite references...
      Don't bother, I've seen them. 99% of them make the same mistake you are, they confuse the passenger services of the big railroads with the passenger operations of the intraurbans. These are two very different markets, despite superficial similarities.

    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?

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.

In order to derail the mag-lev train would have to rip the track apart. Additionally, since the train is wrapped around the track and doesnt just sit on it like conventional trains do, its possible to superelevate the track (track rises on one side as it turns). Superelevation is used to counteract the centrifugal forces as a vehicles makes a tight turn at fast speeds.


    Couple of things wrong with this...

    For starters, unlike the German Transrapid, the Japanese maglev design consists of a roughly u-shaped track which the train sits inside of. Basically, very difficult for the train to derail, but in this case it is the track that wraps around the train (at least this is how they were doing it five years ago, I suppose the Japanese might have changed their design since then).

    As for superelevation, it is not a characteristic unique to maglev designs. Ordinary steel rail, even in the backwards US, is usually superelevated in the turns. The trouble is that with the relatively narrow track gauge, and with the relatively tall rail cars that need to be stable even when the train is standing still on the corner for whatever reason, the amount of superelevation they can use is limited. Just like highways - they could superelevate onramps and turns much more than they do, and make it more comfortable to travel at high speeds, but it is extremely uncomfortable (and unstable for large trucks) if for some reason (traffic, accident, stall, whatever) you need to stop on the turn. Maglev doesn't really have this problem, as the train is wrapped around the track (or vice versa), so a little more superelevation could be used.

    On a side note, a year or two ago I heard about a group (I don't remember if it was the Germans, Japanese, or someone else) taking people up in passenger jets and doing some various g-rate (different amounts of banking, etc.) turns to see what the limits of passenger comfort were.

    GM, firestone & Philip's Petroleum created a front company that purchased over 400 suburban railway & tram systems in the US, then ran them down & replaced them with buses. They even got a $10,000 fine when the govt prosecuted them under the anti-trust statutes. Yep they destroyed infrastructure that today would cost millions or billions to replace for a then $10,000 penalty.

    If it wasn't for that fact, many US cities today could [b]potentially[/m] have suburban railway systems as extensive as Sydney's suburban & inter-urban Cityrail system

    Really AFAIC railways systems should be publically run & financed through consilidated revenue, just as roads are. Public transport will never reach it's full potential while it's expected to make a profit (or break even), while there's no equilivent expectation in regards roads

    I cant see how you think maglev is any safer. You now have to worry about power failures while your traveling at a high rate of speed.

    Japanese maglevs have rubber-shod wheels that the trains sit on when they're not levitating. If a train loses power, then it will settle onto the wheels and then be stopped mechanically (i.e. with friction brakes) by the conductor or by remote control.

    By the way, most maglevs have emergency power supplies that are designed to maintain levitation and electrodynamic braking capability in the event of power failure.

    Those are just two safety measures among many that are built-in to this type of system. It's naive to assume that the designers of these trains haven't thought about the types of things that could conceivably go wrong with them.
