And still: it does not mean the train can not be propelled off the tracks by a foreign object on the track.

Every time, new technology triggers concern. The engineer needs to prove safety. The maglev generates much excitement in the railroad industry.

In any case, wouldn't these same rules apply to a regular train (or even transrapid's train). The wheels on a conventional train don't have any power to stick it to the ground.

If it were feasible for a train to lift off in an accident of some type then I'm sure it wouldn't matter the propulsion method.

The magnetic field, in fact, helps to stabilize and lock the train into place. No it's not quantum locking but magnets do tend to try to keep in alignment.

The wraparound design may look less in danger of flying off the rails but if you think about it would be just as catastrophic. Those underwings will do very little to keep the train from leaving the track.

So has some kind of detection system been built into the track to warn against objects on the track? Or will it be monitored by cameras?

You really do not get it, do you.
As I have posted before there are all the same, Meissner effect is Quantum locking which is flux pinning. They repels magnetic field and thus bend the magnetic field around it.
The end cause is the magnetic field will hold the superconductive material within the magnetic field unless there is strength stronger then the magnetic field to dislodge it.

Maglev toy train goes on sale, and it actually floats.
But to be careful - the mechanism this toy maglev floats is not the same as the real one.

Is it sad that this man-child actually wants one?

No I reckon this version, also from Takara Tomy, is much more hi-tech:



Its even got a modern train activation whistle!

Wheels......lol

But seriously, simulating the actual maglev suspension mechanism in the size of toy is an engineering challenge.

A fast moving maglev trainset induces current in the wall coils, and the induced current generate a magnetic field that levitates the trainset.... Doing this in toy scale will require either the toy maglev moving at ridiculously fast speed or pumping up of the magnetic field by external power supply, which will make it incredibly expensive

The one above LinearLiner also offered from TakaraTomy, operates on the same principle as a Maglev and as you mentioned it is incredibly expensive with a price tag of 35,000 yen to start sales from September this year.

I've been looking everywhere for more information on the record 603km/h run. All that I can find is piecing things from YouTube. It took 22km to reach 603km and it kept up that speed for 10 seconds. However, I haven't found anywhere how long it took to reach that speed.

I saw another video in Japanese which seemed like it would reach 500km/h in 2 minutes. Also, I haven't seen anyone comment on if that acceleration is felt more than the Shinkansen. It's considerably faster than the N700, which reaches 300km/h in 3 minutes.

Note: In comparison, the TGV took 12m40s to reach 574.8 km/h.

Aircraft accelerate to almost 300 km/h in less than a minute. That pushes you back into your seat somewhat.

I think the acceleration in the maglev will push you back into your seat far less than that. At least I know the 431 km/h acceleration of the Shanghai Transrapid did.

Aircraft are also inclined slightly in flight which makes it seem like it's accelerating faster than it is.

I wonder how the acceleration of the jr maglev compared to the transrapid version.

I think accelerating to 500 km/h on the maglev will be very comfortable.

What is the status of the Chuo Shinkansen. When will the construction work between Tokyo and Nagoya begin? Last time I checked in, the news said work shall begin in early 2015.

It already has. I believe there is a picture of showning construction taking place within this thread.

There is not much information regardinng the construction progress at all, I have looked around and couldn't find anything.

I know platform construction has begun at Shinagawa station, but has tunneling works started?

No construction updates, but this is a video of a recent trip to the Maglev Exhibition Center.
Starts with some passes of the Maglev vehicle and then goes into a scientific explanation of the principles with a demonstration. It then finishes with a short movie of how an actual trip would take place between Tokyo and Osaka.

Yes: http://www.sankei.com/economy/news/1...270031-n1.html

Taisei Corporation started tunnel construction. But "started construction" does not mean tunnel boring machine is already in place and digging.

http://www.yomiuri.co.jp/economy/201...YT1T50085.html

Construction of Shinagawa station went to a joint venture lead by Shimizu Corporation.
