Pudong Airport is opposite Longyang Road Station. Shanghai maglev train is the first maglev line in China and the first demonstration line of maglev train put into commercial operation in the world. The interior of the train is divided into VIP cars and ordinary cars. Passengers can enjoy the scenery of Pudong on the train, and it feels like flying at low altitude. Maglev train is a high-tech means of transportation that uses the attraction and repulsion between magnetic poles. 1922, German engineer HermannKemper put forward the principle of electromagnetic levitation, and then applied for a patent. It realizes non-contact suspension and guidance between the train and the track by electromagnetic force, and then draws the train by electromagnetic force generated by linear motor. Maglev trains can be divided into two categories: the normally conducting type and the superconducting type. The levitation air gap of the normally guided maglev train is small, generally 8-10 mm; The levitation air gap of superconducting maglev train is large, generally 100-200mm.
