China has launched the world’s first suspended maglev line built with permanent magnets that can keep a “sky train” afloat forever, even when it is not being supplied with power. The 800-metre (2,600-foot) experimental Red Rail in southern China’s Xingguo county, Jiangxi province, used powerful magnets rich in rare earth elements to produce a constantly repelling force strong enough to lift a train with 88 passengers in the air. Unlike most existing maglev lines, the suspended rail operates about 10 metres above the ground. There is no physical contact with the rail as the train moves underneath the rail at a speed of 80km/h (50mph).
