Currently two lines completed I assume, the Shanghai Pudong maglev and the Changsha Huanghua Airport line under test

China's first maglev train starts full-load test

A full load-test for maglev trains is being conducted in central China's city of Changsha. The trains will run on China's first domestically designed and manufactured magnetic levitation railway.

Can you state the advantages and disadvantages of this form of transportation for our forum users please?

Very short, for maglev:

advantage:
very fast
lower drag/resistance

disadvantage:
very expensive to build
very expensive to operate

Or do you mean the low speed version?

Proponents claim that the operations costs are atually markedly lower than steel-on-steel systems. Far less wear and tear as well as lower energy costs when going to high speeds.
Construction costs are also claimed to be higher mostly due to far lower volume of construction and less experience.

Yeah, only two lines and both are city to airport links, hardly long distance IMO. In that video tjrgx posted it is said the Changsa line will only go at 100 km/h! If so, then what is the point of maglev? The Shanghai line is does over 400km/h every day. That's a speed that would make a great deal of sense for long distance lines.

Realistically what are the chances of a long distance maglev line being built in China?

Well, I will say the answer to your question will depend on time frame.

Within the next 10 year, basically zero chance.
10-20, I will venture to guess 10-20%
20-30, I will say probably greater than 50%
30+ years, I am willing to bet that at least one long distance line will be built.

I think the real push on Maglev will happen when 1) once it is proven it can travel at a speed of 500+ km/h safely and efficiently, and 2) it can carry large enough amount of passengers.

At current performance and payload, there is not a lot of practical advantage over high-speed conventional rail as a mass transit vehicle. However, just like any new technology, I believe its day will come.

In others words it has to prove to be economical to build and operate carry the same number of passengers over the same distance in less time that conventional HSR?

That's my take too, plus that there has to be a need for the capacity the new line would bring. Unless there is a need for another line between for example Beijing and Shanghai then there won't be one built and thus no chance of a maglev built there. However, should there be a need to add another line on a stretch that already has conventional HSR? Then the chances of the new line being maglev goes up IMO.

Speed is not the only strong point of maglevs, especially the mid-speed maglevs in which can negotiate steeper hills, reduces noise pollution, can accelerate and decelerate more quickly and, with same cabin space the height of the overall cars can be reduced making tunneling more cost efficient.
The down side at the moment is it's sticker price and not compatible with legacy tracks.

Just rails . Not many maglev train manufacturers. But they're saying Changsha maglev would cost significantly less than "LRT".

I think capacity is still a major problem for maglev.

I was able to get out to Changsha to see the maglev for myself.

Japan is already investing tens of billions of US$ in the maglev Chuo Shinkansen, which will enable to complete the 286 kilometer-long journey from Tokyo to Nagoya in 40 minutes by 2027 at a top speed of 505 km/h.

Is it on some kind of 'training wheels' ? Maybe they were testing the emergency wheels? It does not sound levitated to me.

Where do you see the wheels? The levitation isn't at a meter above the tracks, it's actually very close to the tracks. But there is air between the tracks and the trains magnets both above and below the track.

I don't see any wheels, but when the trains pass, you do hear some kind of metal on metal contact, so perhaps there are guide rails on the side to keep it in place?

It is much less quiet than expected from maglevs.
