Took a 3-day business to Shanghai, China, so I had a chance to take the first (maybe the only at this moment) commercial operating meglev train in the world. The rail is between Shanghai Pudong Airport and Longyang Road. It takes about 7 minutes for this trip, and the train only takes about 3 minutes and 12 second to reach the top speed at 431 Km/h. It only remains the top speed for around 20 seconds, then starts to reduce the speed.
It is quite an exciting experience for this kind high speed on the ground. But the train becomes shaking after reaching the speed of 380Km/h. I am really curious about the safe speed of maglev train for a long distance operation.
