China's First Engineering Test Line For High-temperature Superconducting High-speed Maglev Has Been Completed And Put Into Operation.

Recently, China's first high-temperature superconducting high-speed maglev engineering test line was officially completed and put into operation in Chengdu, Sichuan Province. This marks a key breakthrough in China's high-temperature superconducting maglev transportation field, from laboratory research to engineering application. The test line is 1.9 kilometers long and designed for a speed of 600 kilometers per hour, making it the world's fastest high-temperature superconducting maglev test facility currently under construction.
According to the project leader, the high-temperature superconducting maglev technology uses superconducting materials cooled by liquid nitrogen to achieve zero resistance and complete diamagnetism, creating a suspension gap of more than 10 millimeters between the train and the track. It has significant advantages such as no friction, low noise, and low energy consumption. Compared with traditional maglev technology, its construction cost is reduced by about 30%, the maintenance cycle is extended by 50%, and it can operate stably in an environment ranging from -20℃ to 60℃, adapting to China's complex geographical and climatic conditions.
After the trial line is put into operation, continuous manned operation tests will be carried out, with a focus on verifying the vehicle's dynamic performance, system integration reliability and emergency response capabilities. A Chinese Academy of Engineering academician pointed out that the breakthrough of this technology not only provides a new solution for China to build a three-dimensional transportation network of "high-speed maglev + aviation + high-speed rail", but also promotes the technological upgrading of related industries such as high-temperature superconducting materials and cryogenic refrigeration. Relevant patents have reached more than 120.
At present, the R&D team has initiated the planning of a 5-kilometer test line and plans to complete the full system joint debugging and testing of a 600-kilometer-per-hour high-temperature superconducting high-speed maglev by 2025, laying the foundation for future commercial operation. Industry insiders believe that high-temperature superconducting high-speed maglev is expected to become another "national business card" in China's transportation equipment field after high-speed rail.
