JAPAN | Maglev

[Vapour]

NAGOYA (Kyodo) Central Japan Railway Co. (JR Tokai) will aim to replace bullet trains with maglev services between Tokyo and Nagoya in 2025, JR Tokai President Masayuki Matsumoto said Thursday.

On bullet train services using the maglev system being tested on an experimental track in Yamanashi Prefecture, he told a news conference, "We would like to aim at launching commercial services between the Tokyo and Nagoya areas in 2025."

The existing Tokaido Shinkansen Line system has reached its limits in terms of technology and transportation capacity, he said.

Matsumoto said he will "take the initiative" in utilizing the JR Tokai-managed line for the maglev.

It is the maglev Chuo line wich will deserve Shinjuku station isn't it ?

This is old news! The Japanese have been anouncing the Maglev from Tokyo to Nagoya and/or Osaka form almost 20 years. For some reason it just never gets built.

Well its quite pricey you know.

[Tri-ring]

I wonder how fast they will set the service speed at.
We still have a good 15 years for development.
I wouldn't be surprised if it reaches 750Km.

It could be possible to travel from Hokkaido to Kyushu in just 3 hours or less if this maglav is built!

The running test of JR－maglev is jostling this year. It will exceed 600km/h comfortably

Do they really plan this, or is it an assumption that they want to try that out?

[gladisimo]

it's practically a plane, but on land. I have to take the Shinkansen once in my life.

[Knuddel Knutsch]

If they want to start service in 2025 they have to start construction around 2013-2014, if they have one year test service, which is quite usual for such big projects.

That means they have 6 years for planning now.
Acutally a pretty tight timetable, for such a big project.
Did they set a timetalbe for when they want to start construction?

[giovani kun]

currently maglev technology is the only one that allows us to travel at trully high speed go nihon

Please site a source (english language) for these claims of 600 or 800 km/h?

[pflo777]

the claim of having a train thats able for reaching 600km/h sounds crazy at the beginning.

But remember that all the Systems and the propulsion technology of the Transrapid 08, which was put into service in 1998 was already able to reach 550 km/h in everyday service. so going to 600 is just 10%higher, and these 10% are usually considered as safety buffer...

To sad, that they never built a track thats long enough to test it....

It's already being tested at 500Km normal testing speed and marked somthing like 580Km so as I wrote in my earlier post it is not out of realm possibility to go up to as fast as 750Km when they make their launch at 2025.

he interior looks like the interior of an airplane. very nice

[Andrew]

Can we actually have some sources for these speeds please?
600km/h sounds feasible but I want to know where the figures of 750 and 800km/h come from.

There is no source since it is just a speculation but research of high temprature super conductive material is relatively new with much headway. The present speed limit is based on the strength of the super conductive magnet and how fast it changes it's polarity.
Hitachi jointly with JR Tokai recently announced they have discovered a material that displays super conductive magnetism of 0.05 Tesla at temprature using freezing machinery.Their goal is to create a material that can be mass producted which can create a 1~2 Tesla magnetic field at temprature obtainable using freezing machinery.

I'm sceptical of the claims of such high service speeds. While technically quite possible it would almost always be uneconomical to do so. I do find superconductors quite fascinating though, who knows where they could lead...

Economic feasibility has always been a concern and that is one of the reason why it has been postponed for such long time.
With stronger superconductive materials retaining it's features in temperatures obtainable with freezing machinery makes it economically viable to compete agaisnt other method of transportation.
With stronger magnets it means less guide coils is needed to be embedded within the course and higher temperature means you do not have to use cost prohibitive liquid Nitrogen, Helium or Hydrogen.
These super conductive materials will also have many other applications.

[Knuddel Knutsch]

its economical feasable, as soon as electrical energy is cheaper than fuel for an (domestic) flight from Osaka to Tokyo....

By the story that I asked a researcher of a friend, as for Maglev, 1000km/h seems to be possible theoretically.

I don't understand the "320 by two wheeled" and "400 by four wheeled
I agree that MagLev could theoretically operate at 1000 km/h . Theoretically!!
I am confident that the initial operating speed of the JR MagLev line between Tokyo and Nagoya will be between 500 and 600 km/h. The Japanese will have to test their new MagLev trains at up to 25% faster then the proposed operating speed to recieve certification of safty so I expect to see test running in the next few years at up to 700 km/h. But I believe that we are along way from normal operating speeds in excess of 550km/h.
