Scientists have built Red Rail, the world’s first maglev ‘Sky Train’ that uses magnets to float without power. Located in in southern China’s Xingguo county, Jiangxi province, this experimental 2,600-foot Red Rail boasts powerful magnets that produce a constantly repelling force strong enough to lift a train with 88 passengers in the air, even without a power supply.
Maglev trains are nothing new, but this one operates approximately 32.8 feet (10 meters) above the ground. It makes no physical contact with the rail as the train moves underneath the rail at a speed of 50mph (80km/h). The train’s arm encompasses the rail and permanent magnets, resulting in both repelling each other. Since the train is free-floating and there is very little friction, only a small amount of electricity is needed for propulsion. What could be next? Possibly a fusion magnet-powered train using MIT’s invention.
