Where does the maglev train pass?

Maglev train is a kind of train driven by magnetic attraction and repulsion. Because of the magnetic force of its orbit, it is suspended in the air and does not need to touch the ground when walking, so its resistance is only the resistance of air. The maximum speed of maglev train can reach more than 500 kilometers per hour, which is even faster than the 300 kilometers of wheel-rail high-speed rail, so it can become a competitor of aviation. The research of magnetic levitation technology originated in Germany. As early as 1922, German engineer Herman Qiangsuo put forward the principle of electromagnetic levitation, and applied for the patent of maglev train in 1934. After 1970s, with the increasing economic strength of the world's industrialized countries, Germany, Japan, the United States, Canada, France, Britain and other developed countries began to plan to develop magnetic levitation transportation systems to improve their transportation capacity and meet the needs of their economic development. However, the United States and the former Soviet Union abandoned this research project in 1970s and 1980s respectively. At present, only Germany and Japan continue to study the magnetic levitation system, and both have made remarkable progress.
