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.
for those of us who don't use that artificial metric crap. I mean, really, if God wanted us to use the Metric system, he would have made the distance between the King's nose and his thumb to be exactly one meter.
I just wish the US would invest in more passenger trains. They don't have to be super fast (like the one in this article), but imagine how much fuel/electricity we could save if we could all easily commute by train. And hey, you can always sleep on the train on the way to work, something you can't do while driving. (Or rather, something you shouldn't do, I'm sure someone's tried it.)
The maximum speed for a maglev train is considered to be around 580 kph due to limits in electrical facilities for the train, the engineers said.
We haven't seen nothing yet. It seems the more juice, the higher the speed. I for one hope to see mass production of Maglev trains. They will be vastly superior to planes at less cost.
I can't help thinking that maglev train development will help achieve cheap spaceflight as well. Imagine a spaceplane taking off from a maglev hitting 1000+ kph.
kph parses as kilo*pico*hour. It makes no sense.
You probably mean km/h.
No need to bastardize a fine international standard.
And much less hassle as well.
Train:- Arrive 5 minutes before departure.
- Get on.
- Travel, with passport check on the way.
- Get off.
Airplane:I, for one, welcome our new super-fast trains. I've used the 300kph trains (TGV,Eurostar,etc) and they are a really nice way to get around. For travelling within continents, these will a far better alternative than flying.
Forget thrust, drag, lift and weight. Airplanes fly because of money.
In France , the TGV derailed at least two times in 20 years. Each times at more than 250Km/h (150mph) No injuries, No deaths.
Because the train is linked upon boggies.
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?
Divide et impera!
God measured in cubits.
Also, 581 kph = 116.5050712 microparsecs per century.
You're forgetting that you can even take a comfortable night train and sleep while you travel. I do this with my family when we need to cover a "one night's distance". We loose less "wake time" and we arrive in a better shape.
I hadn't the slightest objection to his spending his time planning massacres for the bourgeoisie... (P.G. Wodehouse)
I wonder if moving that fast causes problems with train-land wi-fi and cell networks due to the doppler effect? Imagine you're screaming toward a cell tower at 167 m/s (600 km/h) - that's a doppler shift of 500Hz at 900MHz, which I imagine could cause some problems.
This is so wrong.
SWITCHES?
Nothing deployed? The Germans and chinese will be very upset that they do not exist
Then the mention of lack of land, all the while ignoring that the train is elevated.
Earthquakes? well, since the train is elevated, the supports are designed to handle earthquakes. It is LRT and Heavy Rail that has problems due to the fact that they are heavily anchored to the earth through every inch of the rail. This allows for the rail to be moved from underneath the train while it is moving.
BTW, In japan, the monorails have had NO problems with earthquakes/Typhons, etc, while LRT has to be stopped and adjusted after each item.
Cusion of air for aerodynamics???? It is a "MAGLEV"; it is supported by magnetic force, not aerodynamics.
As to evironmental impact, give me a break. The amount of force is FAR less than an MRI.
I prefer the "u" in honour as it seems to be missing these days.
Seriously, if you're not willing to pay tax dollars for rail infrastsructure, why also pay for roads and bridges? And while you're at it, why not dismantle the education system and courts as well? When private enterprise performs all of these civic functions, will "freedom" have been expanded or will we simply have seen a net transfer of power away from voters into private hands? Just asking. --M
Actually, the one in Shanghai, PRC, has been 'deployed'.
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.
Really ? So what, exactly, do you call this thing then ?

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.
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.
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.
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
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.
Kids these days put their coins in Tesla coils anyway
Yep, a TGV recorded 515.3 km/h (320.3 mph) back in May 1990, not bad at all.
