China News Service, Chengdu, January 13 (Reporter He Shaoqing) The world's first high-temperature superconducting high-speed maglev engineering prototype and test line using the original technology of Southwest Jiaotong University was officially opened on the 13th in Chengdu, Sichuan Province.
This marks a breakthrough in the engineering research of high-temperature superconducting and high-speed maglev from nothing, and has the conditions for engineering experiments and demonstrations.

It is understood that the high-temperature superconducting maglev train technology is planned to be engineered first in the atmospheric environment, and the expected operating speed target value is greater than 600km/h, which is expected to create a new record of land traffic speed in the atmospheric environment.
The next step is to combine future vacuum pipeline technology to develop a comprehensive transportation system that fills the gap in land transportation and air transportation speeds, laying the foundation for a long-term breakthrough in speeds above 1000km/h.

The completion of the high-temperature superconducting high-speed maglev engineering prototype and the test line project is an important implementation step to promote the engineering of the high-temperature superconducting high-speed maglev train technology, which can realize the suspension, guidance, traction and braking of the high-temperature superconducting high-speed maglev prototype And other basic functions, as well as the joint debugging and joint test of the entire system engineering, meet the later research test.
Combined with the maglev train model test bed in Southwest Communications University, it can verify the high-speed superconducting maglev train and its long-term reliability.
According to Yang Dan, President of Southwest Jiaotong University, the HTS maglev train technology was born in Southwest Jiaotong University as a revolutionary technological creation.
The school began the development of maglev in the 1980s. After nearly 40 years of scientific research, it has formed the theory of vehicle-mounted high-temperature superconductor-permanent magnet orbit interaction, established a high-temperature superconducting maglev electromagnetic thermal multi-field coupling model, and broke through the large load, The high-speed, high-temperature superconducting suspension technology has the conditions for engineering.
