Shanghai Maglev Train, the first MAGLEV line in the world. When it was built up, more than thirty kms which was from Pudong Dragon Road to the Pudong International airport, just spent six to seven minutes. Shanghai Maglev Train was the normal conducting type maglev train. It was designed by "Opposites attract" principle which was a attract suspension system, installed in the train on both sides of the bogie suspension electromagnet, and laying on the track of magnets in the magnetic field to produce the suction vehicle float.

The normal conducting type maglev train controled the current in the electromagnet accurately, so keep 10 ~ 15mm gap between the body and the guide rail, while ensuring a smooth suspension reliability and train running and the motor power output. This suspended way needn't to set up a dedicated ground support equipment and the ground round of auxiliary.To TR series of the Germanic maglev train as a representative, its speed could reach 400~500/kilometers, and it was mainly fit to the long-distance high-speed transportation between cities; in addition, the efficiency and speed of the HSST series of the Japanese maglev train was lower, and it was mainly fit to the slow running.

The idea to the normal conducting type maglev train was came out in 1922 by Herman · Kemper, a engineer from Germany.

The normal conducting type maglev train and the track were the same with the working principle of the motor. It was the super express in the 21st century, and was much accounted of all over the world. Nowadays, our country is reserch this express with Japan, Germany, UK, USA.
