At present, rail transit is mainly divided into subway, high-speed rail, bullet train and ordinary train. The cost of maglev train is similar to that of high-speed rail, and the operation cost is much lower than that of traditional high-speed rail. Japan's 600km/ h Tokyo Nagoya Line is expected to open to traffic in 2027. The United States (hyperloop), Russia, Brazil and other countries are vigorously developing high-speed maglev trains. China Aerospace Science and Industry Group and other units have initiated projects to develop superconducting maglev trains over 1000km.

     In 2022, the company developed the superconducting magnet system for the superconducting maglev train with a speed of 623km, which set a world record. The experimental overload exceeded 30G! Up to now, many research institutes and enterprises have supplied superconducting magnets for maglev trains in bulk, and have reached long-term cooperative relations. Xi 'an Polymer magnet has laid the foundation for the development of superconducting magnets for high-speed maglev trains in the field of rail transit, and has become the preferred equipment service provider in the domestic industry.
