Researchers at a university in southwestern China say their approach could mean super fast but cheap travel.
China rolled out a prototype of a state-of-the-art maglev vehicle that its developers said could herald cheaper and faster next-generation magnetic levitation train transport, even approaching the speed of some planes.

Researchers at Southwest Jiaotong University unveiled the new maglev train and 165-metre (540 feet) test track in Chengdu on Wednesday.
