China has set a new world record by accelerating a superconducting electric maglev test vehicle to 700 km/h in just two seconds. Researchers at the National University of Defence Technology conducted the test on a 400-meter track, demonstrating both extreme acceleration and safe deceleration. This achievement in ultra-high-speed magnetic levitation technology resolves core technical challenges and signifies a major advancement in China's high-speed transport development, with potential applications in future concepts like hyperloop systems.
