We started off day three with a ride on the world's fastest train, the Shanghai Maglev, with a top speed of 431 kph (268 mph). For those who don't already know, the word Maglev is short for magnetic levitation. Basically, that means this train uses powerful electromagnets to hover only about 1/3 inch above the track, which eliminates friction. Propulsion is also achieved using electromagnets, creating a very fast, quiet, and efficient means of transportation. At top speed, a maglev train is about twice as efficient as a car and three times as efficient as an airplane.
