China has unveiled a maglev train capable of a top speed of 600km/h, state media said this week.
The maximum speed would make the train, self-developed by China and manufactured in the coastal city of Qingdao, the fastest ground vehicle in the world.
Using electro-magnetic force, the maglev train "levitates" above the track with no contact between body and rail.
China 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.
While 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.
With the ability to reach 600km/h once it gets up to speed, it's estimated it would only take 2.5 hours to travel from Beijing to Shanghai by train - a journey of more than 1200km.
The journey takes a comparable amount of time by plane and 5.5 hours by high-speed rail.
Launched in October 2016, the high-speed maglev train project saw the development of a magnetic-levitation train prototype with a designed top speed of 600 km/h in 2019 and conducted a successful test run in June 2020.
Engineers have completed the integration of the maglev transportation system, and a train with five carriages has been running well on a test line within the factory, the China Railway Rolling Stock Corporation (CRRC) said.
The train can travel with two to 10 carriages, each holding more than 100 passengers, according to Ding Sansan, chief engineer of the project. The train provides the best solution for trips within the range of 1500 km, Ding said, adding it fills the speed gap between aviation and high-speed trains.
Countries 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.
