    "Beats the Autobahn any day"

    But, but Autobahn is a highway... Besides, the Autobahn does carry more people per hour and kilometers than does this train any time soon.

    If this is like every other "high speed" trains, then it can only keep its maximum speed for short periods of time.

    I believe it's more related with the environment (i.e. "let's not hit a cow") than anything else. So I wonder if they developed a system to allow a constant high speed (other than "we don't care about cows")?

    From the german article not anytime soon. The line is running from the city to, TADA, the airport!

    If anything this thing will make airtravel therefore easier by getting people to and from the airport faster.

    I recently had to go to london from amsterdam and checked out the three different methods. Boat, train (via channel-tunnel) and plane. Plane beat the other by a few hours. Mostly because of the number of transfers(?) and the inevitable waiting time this entails, required in the other two.

    Are these things using Electro-Magnets? Imagine the impact of loosing power. I'd worry about bringing magnetic strip credit cards on board unless I was assured that the magnetic fields wouldn't erase them. This is interesting technology and I'd like to know the answer to these questions.

    Does not beat the French TGV

    The point is: the TGV has once reached a maximum speed of more than 500km/h with a specially designed trainset on special rails, while 400km/h is the usual travelling speed for the transrapid. I see quite a difference there. The TGV does not come close to 400km/h, let alone 500km/h in everyday travel..

    If your goal is just to reduce friction, why not simply float the train on an air cushion, like a hovercraft? It seems like it would eliminate a lot of the complexity.

    The air cushion could be fairly efficient compared to military hovercraft, since the ground clearance could be an inch or so, instead of feet. Your track could be prepoured concrete instead of electromagnets.

    I'm probably missing something.

    Sorry about previous post. Hit "return" when reaching for "shift."

    I myself have discovered (by living in São Paulo and having a girlfriend in Rio de Janeiro) that traveling by bus is already better for me than traveling by plane.
    First, it's much more comfortable. The buses have seats that are much bigger and much farther apart (front-to-back) than airplanes. I am not a big person (173 cm and about 65kg, or about 5'8" and around 145 lbs) and I feel cramped in commercial airliners. Imagine tall and/or heavy people!
    Besides that, on a bus, the seats really recline (not the almost imperceptible 5 "recline" of an airplane seat), making it possible to sleep, which I now cannot do on airplanes (I used to be able to, but they are forever cramming more and more seats in, and thus limiting more and more the space each passenger has, and they have now surpassed my comfort limit). Additionally, there is no limitation on when you can recline the seat (there is no takeoff and landing) or on what kind of electronic devices you can use (it's nice to be able to use my cell phone to make or receive calls while en route) or when you can use them (again, no takeoff and landing).
    Also, you don't have to pass through really invasive security procedures to get on a bus. I also discovered something surprising: even though the bus travels much slower than a plane, I don't lose much time taking a bus. In fact, it's much better. Let me explain.
    If I take a plane, I have to get to the airport first. And I have to be there at least an hour before the flight (it would be 2 hours if I were in the US, but I am fortunate to live in a free country... if anyone thinks this is a troll, I'll be happy to discuss it with you. But basically, I enjoy many freedoms I couldn't dream of having in the US). After standing in a line to check in, I have to answer stupid questions, show ID, and check my luggage. Then I have some time to kill before the plane leaves. I usually get some kind of soft drink in the departure lounge (waiting area). Oh yeh... I have to show ID and my ticket to get in there. With all the noise and hurrying people around, it is all but impossible to make any kind of use of this waiting time by, say, reading. Then they call us to board. I then have to get in another line, present my ticket, and go to the plane. I then find my seat and sit down. I can try to read during this time, but again, there are people all around making a lot of noise and hurrying and arranging their stuff. Then the plane takes off. I can now try to read, but within a few minutes, the flight attendants come around with drinks. In the case of the São Paulo to Rio flight, the whole flight lasts only about 40-60 minutes (depending on direction, weather conditions, and air traffic at the destination). In the case of longer flights, the attendants come around several times to offer drinks and/or food.
    After the plane lands, it taxis to the gate. This can add another 5-15 minutes, depending on traffic. Then we are released into the terminal, which usually involves another wait while people block the corridor to take down the 74 bags they just couldn't check and had to bring on board. The one time I saw a flight attendant enforce the limit on the number of bags a couple could carry on, I literally applauded, and did I ever get dirty looks from the couple.
    Next we all go to baggage claim, which can take anywhere from seconds to forever. After that, either I meet my ride or go to car rental to get a car.
    In the end, I don't really save any time taking a plane instead of a bus, even though the flight part of the journey by plane takes 40-60 minutes and a bus trip takes 5-6 hours. Taking the bus has the added advantage that I can arrive at the bus station without a reservation, buy a ticket for the next bus, go down and wait a few minutes (not 45 like in the airport, plus buses are rarely late, while airplanes always seem to be) before getting on the bus. I can than either sleep (not possible in the airplane due to comfort and time constraints) or actually do some work or just relaxing reading. If I had a laptop, I could do work too. Also, buses have much more flexible hours. In the Rio-São Paulo example, the last plane (and you've gotta reserve that several days in advance) leaves around 10:00 PM. There are buses leaving with relatively high frequency until about 1:30 AM, and there are others that leave at even later hours, though not as frequently.
    Now imagine a train, which can offer all the advantages of buses, plus it doesn't get affected by traffic and can travel at 400 kph (about 250 mph). Add in that it can be much more energy-efficient than a plane, has an even lower risk of accidents, and (Steven Seagal movies aside) an even lower risk of hijacking than a bus, since it has very limited possibilities in terms of alternate routes (i.e., it can only go where there are tracks) and basically cannot be used as a weapon (except possibly against a vehicle on a road at a train crossing or another train). Basically, there's no comparison. A maglev train would blow away an airplane for everything except trans-oceanic travel. And best of all, it would probably be much cheaper than an airplane flight. I started taking buses because my girlfriend and I couldn't really afford to be flying back and forth every weekend, and the bus is a much, much cheaper option. I expect a maglev train ticket would be more expensive than a bus ticket, but less expensive than a plane ticket. I traveled extensively in Europe by train, and the prices were quite reasonable, even for the TGV (Train de Grande Vitesse (or sumfin' like that), which just means "high-speed train" in French) between some Swiss city (Geneva?) and Paris. And if you think about it from a business point of view, the marginal cost of adding space for more passengers (by adding more cars, not by cramming the passengers in like sardines like the frickin' airlines insist on doing) is very low. So if there is less demand, you send less cars. If there is more, you add some. So the "full flight" problem is reduced without large additional costs... wow.
    If I were a stockholder in a major airline, I would be even more worried now than before thinking about high-speed maglev trains... as a consumer of mass transport, I am definitely more happy than before thinking about these things because of the /. article.

    The train itself has batteries which have enough capacity to levitate it for about an hour. In case of a power-failure during travel the train would continue to float until it stops.

    There is no magnetic field in the cabin, credit cards, etc are safe.

    The "real" speed of this can only be estimated since currently there is no track long enough to give the train the chance to accelerate until the air drag is as high as the power of the impellent. It is estimated at about 600 km/h, AFAIK.

I see quite a difference there. The TGV does not come close to 400km/h, let alone 500km/h in everyday travel...
    Nitpick: the world-record was made by a souped-up perfectly normal beas^h^h^h^h TGV fitted with a bigger transformer, bigger wheels, a smaller gearing ratio, 7 less cars than normal, various aerodynamic optimizations and a stiffer-than-normal catenary.

    And TGVs everyday come 80 km/h close to 400 km/h on the newest high speed line, the LGV Médditérranée where the top commercial speed is 320 km/h (that's exactly 200 miles per hour). And they are routinely tested at 400 km/h, and most journalists invited for the ride don't bother showing-up.

    So a pityful maglev is laughable.

    The current S-Bahns can be sped up to 160km/h (from a current 80-120, generally), which would take the travel time down to 16 minutes versus the expected 10 for the Transrapid.

    Yeah, I think it should be rather obvious that maglev trains are not suited for distances as short as this. It is weird that they would even plan to use it for city-to-airport connections. This is not going to be useful for distances shorter than a few hundred kilometers, but given that these trains can go from city-centre to city-centre, they can shorten the time it takes to travel between cities considerably. Therefore, I would expect maglev trains to eventually be competitive on distances between 400 and 1500 kilometers. But it seems to take longer than I would have guessed 15 years ago.

    To make things worse, the video schedule displays along the lines run Windows and crash at least once a week. Luckily, the trains don't.

    Which reminds me of a trip I had with one of the newest trains here in Norway. I happened to be seated beside an american who worked in the telecom industry, and he said that before I entered the train, the train had stopped for a few minutes, and they said on the speaker "we are standing still while the onboard computers are restarted". We both went: "Uh-oh, I hope they're not running Windows on those control systems"...

    Many years ago, I worked for a (far) different division of a company heavily involved in development of MagLev trains. When I used to see them in their glossy corporate brochures ("Transportation of the Future"), I would roll my eyes and think "this will never get beyond the prototype stage". I may have to revise my opinion.

    I have driven in Germany many times, and can attest to fellow North Americans that the Germans take their driving far more seriously. They obey the speed limits right down to the km/hr., where they exist (secondary and city roads and many parts of the Autobahn), and on the stretches of Autobahn that are unregulated, they obey rules very carefully about slower traffic keeping to the right, proper signaling, passing etc. North American driving looks very sloppy in comparison. The sections of the Autobahn that are unregulated are (by comparison to here) beautifully engineered, built and maintained (flat, smooth, properly banked turns, etc.).

    A few years after the wall came down, I drove from Berlin to Bavaria through the former east (Leipzig, etc). There was massive Autobahn (and everything else) reconstruction was under way. There were sections of new road that were like a glass table interspersed with sections that were like an old washboard - quite a difference. Oh, and there were a lot of Trabants on the road in the "former East". For those who haven't seen them, picture a small toaster on wheels with blue smoke billowing out the back (2-stroke engines) and a top speed of about 80km/hr. (~50 mph). I remember seeing a Trabant pulling a trailer that had a brand new Mercedes 500SEL on it and thinking it ironic. After passing another Trabant on a slight curve on the Autobahn, I looked in my rear-view mirror and saw its passenger side door fly open. The car is so narrow that the (large) driver was able to reach over the passenger, grab the passenger door handle an slam the door shut while still steering the car.

    Interesting curiosities: I was told that in Germany, if you come up behind another car and want him to move over, you can be charged for flashing your lights at him and that you can also be successfully sued for giving another driver the middle finger gesture.

    That's still fairly worrying, though. It implies that in the event of a power failure, you now have a floating missile travelling at 250 mph towards the next station, with no way of braking, and (since it's floating) almost no frictional braking...

    Uh, what part of Germany was that? I *rarely* see Germans pay much attention to the speed limit, unless of course they know there's a radar camera nearby (in which case they slow down for maybe a few seconds).

    I've lived in Germany now for almost ten years (Hannover-Hamburg area) and speeding (and trying to run red lights) seems to be the national sport.

    where they exist (secondary and city roads and many parts of the Autobahn), and on the stretches of Autobahn that are unregulated, they obey rules very carefully about slower traffic keeping to the right, proper signaling, passing etc.

    That I agree with -- indeed it's often a shock to be back in the States and drive there, where passing on the right is pretty much normal (even if it's technically illegal).

    OTOH it's not that big a deal, since the speed differential between any given car and the average speed is *far* lower (cars in the States drive about 70 +/- 10 mph; in Germany it's about 85 +/- 30 mph because of varying speed limits by type of vehicle) so passing on the right isn't that big a deal.

    North American driving looks very sloppy in comparison. The sections of the Autobahn that are unregulated are (by comparison to here) beautifully engineered, built and maintained (flat, smooth, properly banked turns, etc.).

    Yup, it never ceases to amaze me how perfectly built the Autobahnen are. But OTOH think about it this way: with the high speeds, you *have* to have a perfect surface -- otherwise the car would go flying at the first pothole (or take out the whole suspension).

    Interesting curiosities: I was told that in Germany, if you come up behind another car and want him to move over, you can be charged for flashing your lights at him and that you can also be successfully sued for giving another driver the middle finger gesture.

    Yes, both are true. Honking or flashing your lights at someone to get them to pull over is called "Nötigung" (basically means "forcing") and is punishable by law. Tailgating is also considered a mild form of Nötigung. In both cases you're encouraged to take down the license plate and turn them in (though I don't know if the plaintiff gets anything for doing it).

    However, the converse is also true. If you're in the left lane and only doing 80 kph, others can sue you for blocking the road.

    Using the finger is an offense in Germany on or off the road, actually, as is insulting someone (calling someone an a**hole is subject to fines). This results in rather interesting twists of conversation -- Germans have gotten rather good at verbally assaulting and insulting people without ever actually calling them anything...
