CNN —China has revealed a prototype for a new high-speed Maglev train that is capable of reaching speeds of 620 kilometers (385 miles) per hour. The train runs on high-temperature superconducting (HTS) power that makes it look as if the train is floating along the magnetized tracks. The sleek 21-meter-long (69 feet) prototype was unveiled to media in the city of Chengdu, Sichuan Province, on January 13. The country’s first high-speed Maglev train, it began operating in 2003. The CR400AF-G train can travel up to 350 kilometers per hour in weather as cold as -40 degrees Celsius (-40 degrees Fahrenheit).
