1 / 10China unveiled a maglev train capable of a top speed of 600 kph on Tuesday, state media said.2 / 10The maximum speed would make the train, self-developed by China and manufactured in the coastal city of Qingdao, the fastest ground vehicle globally.3 / 10Using electromagnetic force, the maglev train 'levitates' above the track with no contact between body and rail.4 / 10China has been using the technology for almost two decades on a very limited scale. Shanghai has a short maglev line running from one of its airports to town.5 / 10While there are no inter-city or inter-province maglev lines yet in China that could make good use of the higher speeds, some cities including Shanghai and Chengdu have started to conduct research.6 / 10At 600 kph, it would only take 2.5 hours to travel from Beijing to Shanghai by train - a journey of more than 1,000 km (620 miles).7 / 10By comparison, the journey would take 3 hours by plane and 5.5 hours by high-speed rail.8 / 10Countries from Japan to Germany are also looking to build maglev networks, although high costs and incompatibility with current track infrastructure remain hurdles to rapid development.9 / 10Using electro-magnetic force, the maglev train 'levitates' above the track with no contact between body and rail.10 / 10China has been using the technology for almost two decades on a very limited scale.
