China Breaks Speed Record with 700 km/h Maglev Train Test

Chinese scientists have reached a significant milestone in the field of magnetic levitation technology. Researchers from China's National University of Defence Technology have successfully propelled a one-tonne vehicle to a speed of 700 kilometres per hour (km/h) in just two seconds. This remarkable achievement occurred on a 400-metre test track, setting a new world record for superconducting electric maglev systems.

Footage of the test, which has circulated widely on social media and Chinese news platforms, shows a chassis-like vehicle rapidly gliding along the track, leaving a misty trail in its wake. This successful experiment demonstrates considerable advancements in both extreme acceleration capabilities and high-power control systems.

According to a report by the South China Morning Post (SCMP), a spokesperson from China Central Television (CCTV) stated, "It resolves core technical challenges including ultra-high-speed electromagnetic propulsion, electric suspension guidance, transient high-power energy storage inversion, and high-field superconducting magnets." This breakthrough could have far-reaching implications for various modes of transportation, including hyperloop systems and aerospace launches.

The same research team had previously achieved a speed of 648 km/h on the same track earlier this year. Their decade-long research efforts place China at the forefront of global maglev technology, marking a significant evolution since the development of the country’s first manned maglev train three decades ago.

Professor Li Jie, who played a pivotal role in establishing Beijing's first commercial maglev subway line, expressed optimism about the future of ultra-high-speed maglev transport in China. He believes that this recent success will accelerate the development of maglev technology within the country.

In 2020, CRRC Qingdao Sifang, a major Chinese train manufacturer, tested a prototype capable of reaching speeds of 600 km/h. Concurrently, Southwest Jiaotong University has been working on a high-temperature superconducting maglev system in Chengdu, aiming for speeds exceeding 600 km/h.

Additionally, a collaborative effort between the Third Research Academy of China Aerospace Science and Industry Corporation and North University of China has resulted in the construction of a 2-kilometre experimental line in Datong. This facility is designed to test maglev trains in low-vacuum pipelines, with aspirations to achieve speeds of up to 1,000 km/h in the future.

The advancements in maglev technology hold the potential to transform travel between cities through vacuum-sealed tubes, as well as revolutionising rocket launches by reducing fuel consumption during takeoff. Furthermore, this technology could provide new avenues for testing high-speed flight equipment through ground-based simulations, enhancing research and development in aerospace technologies.
