CHINA has successfully carried out a systematic test on a cutting-edge transportation system involving an ultra-high-speed maglev (magnetic levitation) train running in a low vacuum pipeline, according to media reports on January 15.

Three navigation tests have been completed in accordance with the test procedures, thanks to the use of a super-navigation vehicle, and all systems work normally when the speed exceeds 50 kilometers per hour (kph) on the 210-meter test route.

Researchers working on the project in Datong in Shanxi province indicate that they aim to build an ultra high-speed mega transport system running in low vacuum pipelines by combining railway and aerospace technology, [...]

The team from the state-owned China Aerospace Science and Industry Corp. hopes they will eventually be able to operate maglev trains in a tube with extremely thin air — meaning they would "fly on the ground" at speeds that rival planes.

The technology of maglev successfully eliminates friction, while operating the train in a low-vacuum pipeline reduces resistance and noise, which are two main problems in train transportation.
[...]

The experiment successfully completed at the beginning of 2023 is the first full-scale super-navigation experiment in China and has verified a series of key technologies, the correctness of the high-speed vehicle system and related coordination work.

The development of the maglev train was made possible, in part, by the rapid development of new industrial materials in China. The maglev track, for instance, needs steel with a low response to a magnetic field. Otherwise, the track will generate eddy currents that can cause a loss of energy during operation, according to media reports.

The development and promotion of high-speed rail remain a major priority in China, which aims to connect more of its vast territory, including not only larger cities but also remote areas, to travel by train to reduce the time and expense for a larger group of people.

[...]

Several new maglev networks are reportedly under construction, including one linking Shanghai and Hangzhou and another connecting Chengdu and Chongqing.

China successfully tested its first high-temperature superconducting maglev system in the northeastern city of Changchun on Friday, marking a technological breakthrough for the country in this field. The operation verified core technologies including superconducting magnets, linear synchronous traction, induction power supply and low-temperature refrigeration, laying a foundation for promoting the superconducting magnetic levitation system, the China Media Group reported.

The system is said to be suitable for high-speed, ultra-high-speed and low-vacuum pipeline application scenarios, Science and Technology Daily reported, citing Yu Qingsong, deputy chief engineer and director of the Maglev Research Institute of Chinese train manufacturer CRRC Changchun Railway Vehicles Co, Ltd. According to Yu, the operating speed can reach 600km/h.

There is no way it can go fast with only 1 cm clearance and although they claim it will go faster than the Japanese SC maglev I have only seen videos of people pushing it.
