Thirty years ago today, on May 11, 1995 (April 12, 1995 lunar calendar), our country became the sixth country to successfully develop a maglev train. The medium and low speed maglev train uses the principle of "same-sex repulsion and opposite-sex attraction" to make the magnet have the ability to resist gravity, so that the car body is completely off the track, suspended at a distance of about 1 cm from the track, and flew into the air, creating a miracle of space flight near "zero altitude". After the completion of the world's first maglev train demonstration operation line - Shanghai Maglev Train, it only takes 6 to 7 minutes to travel more than 30 kilometers from Pudong Longyang Road Station to Pudong International Airport. The train runs in suspension above the rails. The rails are not in contact with the vehicle. It not only runs fast and can exceed 500 km/h, but also runs smoothly, comfortably, and is easy to realize automatic control. It has no noise and does not discharge harmful exhaust gases, which is conducive to environmental protection. It can save construction costs. Low costs for operation, maintenance and energy consumption. It is an ideal super special express train in the 21st century. All countries in the world attach great importance to the development of maglev trains. At present, countries are actively studying this kind of car. Japan's superconducting maglev train has been tested and is about to enter the practical stage. The running speed can reach more than 500 km/h. After which countries, our country is the sixth country to successfully develop a maglev train? Japan, Germany, the United Kingdom, Canada, the United States, and the former Soviet Union.
