Transportation future rail: Maglev, Aerotrain ...

[sen-no-sen]

Following the debate on train VS car consumption:

https://www.econologie.com/forums/consommation-energetique-ep-train-vs-voiture-t10967-140.html

A new subject was necessary concerning the transport of the future on rails (rails, monorail, tube etc ...): their advantages, disadvantages, cost, social / environmental consequence etc ...

At the present time and to my knowledge there are two "trains" with magnetic levitation:

The transrapid:
http://fr.wikipedia.org/wiki/Transrapid
German technology developed in China

And the famous Japanese JR-Mag lev:

Given the high velocity of its machines, it may be the substitutes of medium-haul airlines of the future.

There are others and there are others.

Currently, there is a train in South Korea, which should enter service in 2012, it is in partial service and testing: http://www.monorails.org/tmspages/MagTaed.html

There is also the Linimo of Nagoya which is the only one with the Transrapid of Shanghai to be really in service: http://en.wikipedia.org/wiki/Linimo

An important interest with the Maglev is that there is no wear of the track, it takes a lot of copper but it does not wear (and the value of this copper follows the stock market. .. With the TGV, there is a rapid and significant wear of the track above 300 km / h especially with Jacob type bogies articulated as the axle load is greater.

A point of view (quite personal AMHA) on the aerotrain of Bertin by Liberation:

Oh yes, I had completely forgotten!

Vast subject anyway .... . And not necessarily exciting. What do we begin with ?

Can the TGV run at> 500 km / h on average? https://www.econologie.com/forums/tgv-a-540- ... 65-10.html
The transport of the future would not be the TGV, why?

Is the Aérotrain definitely dead?

What is the interest of the magnetic levitation train?

The TGV has been an evolution in the railway sector, certainly, but the Japanese and the Germans who also has this technology we understood that this was not an end.
Like space research, this is an area that is expensive but yields in terms of innovation.

About Linimo in Nagoya, Japan, three videos:

Thanks for the links, do you have information about energy efficiency with respect to a conventional train / metro (or for linear express).

No, I do not have any information, I have to look for it (in Japanese) it certainly exists, it is necessary to find them. Then, it will compare to a metro tire (Japanese), it exists, because the Maglev Linear Express carries many more passengers much faster.

[Leo Maximus]

I did a quick search and concluded that it was not worth looking for Linimo's energy efficiency:
- The Linimo "flies" at 8 mm above the track and its load is limited to 10,2 tons.
- Its capacity is about 20% that of an equivalent train with wheels or tires.
- Its speed is very limited to prevent "rubbing".
- The traffic on the same line would be 2 or 3 times higher with a good classic metro (which can be quiet, fast, cheap and comfortable) carrying many more passengers.

From where I concluded that it was not worth looking for more.

The Linimo was a demonstration vehicle for an exhibition, it was not dismantled to continue the experiment.
