Note: PML = permanent magnetic levitation technology.
China on Tuesday completed the construction of the country's first independently-developed trial line using rare earth permanent magnetic levitation (PML) technology.
Dubbed "Rainbow," the maglev line that is about 800 meters long was built in Xingguo County, east China's Jiangxi Province.
With a designed maximum speed of 80 kilometers per hour, the rail system now can serve a two-carriage maglev train with a carrying capacity of 88 people. The transit system is equipped with the BeiDou Navigation Satellite System, 5G and intelligent sensing technologies.
The track with rare earth PML technology can keep trains in a state of suspension, which is energy-saving and environmentally friendly.
China’s "Sky Train" levitates power-free on permanent magnet tracks
The benefits of maglev public transport systems are fairly clear: they're nearly silent, they need little maintenance, and they eliminate rolling resistance, so they use less energy to accelerate.

At present, it's just an 800-meter (half-mile) single test track, built on steel poles that lift the track some 10 m (33 ft) in the air. A two-carriage train carrying up to a gratuitously lucky 88 passengers is suspended magnetically underneath the track, making no contact, and it glides along, silent and frictionless, between elevated passenger platforms at speeds up to 80 km/h (50 mph). Once test runs are finished, it'll be extended to a 7.5-km (4.7-mile) track, with a higher top speed around 120 km/h (75 mph).
Obviously, being raised up on poles, it requires less real estate on the ground than a light rail operation, and according to the South China Morning Post, these Sky Trains cost about a tenth of what a subway does – even accounting for the large amounts of neodymium involved. They'll certainly age well on the balance sheet, too – a neodymium-enhanced magnet loses less than 5% of its magnetism in a century, so these facilities could outlast filial piety.
China made a train that floats in the air, if it runs, there is no sound, know the specialty

Beijing: China is once again in the news about its train. But this time China is in the news for its future maglev train. These high-speed trains run on electromagnets on the tracks. China has launched its first air-hanging train line in the country which is made of magnets. It is also known as Red Rail. This train is an experimental project with 2,600 feet long track. It is made in Jingguo County of Jiangxi Province, China.
China’s state media Global Times has released the photo of the train. The magnets of the train produce a force, which causes the train to rise in the air. Only 88 passengers can travel in this train. This train runs about 33 feet above the ground. It has no contact with the track. The most important thing about this train is that when it runs, there is no sound. The speed of the train is 80 kmph, but when it runs, no one knows.
