- Unveiled in Shandong, prototype will be a first step towards ground-breaking high-speed travel that will rival passenger jets, project engineer says
China was a leader in technologies that included suspension, guidance, control and high-powered traction, Ding told Qingdao Daily.
“The test vehicle has been powered up and is in good order,” Ding was quoted by the newspaper as saying.
Taking Beijing-to-Shanghai by plane as an example, Ding suggested: “It takes about four-and-a-half hours by plane including preparation time for the journey; about five-and-a-half hours by high-speed rail, and [would] only [take] about three-and-a-half hours by maglev.”
While earlier reports suggested the prototype was expected to begin full-scale testing by 2020, it was unclear what Thursday’s unveiling meant for this timetable.
More maglevs would join the development project in the coming months, the team leader was quoted as saying, while mass production of the technology was likely by 2021.
In contrast to the optimism of the team at Qingdao, Chen Peihong, professor of economics at Beijing Jiaotong University and a transport analyst, was more circumspect about the future of maglev trains.
“The market has to be bigger. Technology alone cannot make [the concept] a success,” she said.
Plane or train: as high-speed rail link connects Hong Kong to 44 mainland Chinese cities, what are cheapest and fastest ways to get where you are going?
Public transport relied heavily on economies of scale, Chen said. Chinese cities including Jinan, Hangzhou and Chongqing were considering maglev lines, but even the longest – from Jinan to Taian – would not exceed 50 kilometres.
Chen said that electromagnetic fields from maglevs were greater than those from the lines that powered high-speed trains, while environmental worries might keep maglevs out of densely-populated areas.
There was a debate in China in the early 2000s about the benefits of a developing a maglev compared to high-speed rail, researchers on that project said. Rail was preferred by the government because it was an established technology and one that was cheaper to realise.
By the end of last year, China’s high-speed rail network extended to most of the country at a distance in excess of 29,000 kilometres, according to government figures, twice as long as the rest of the world’s high-speed rail lines combined. Spain’s high-speed AVE network was the second-longest at 3,100km.
Elsewhere, researchers in Chengdu, Sichuan province, said a vehicle inside a vacuum tube powered by a superconductor coil from a maglev train – a hyperlink – was in development. They expected the vehicle to reach speeds in excess of 1,000km/h as air was pumped from the tube and resistance to the speeding object gradually eliminated.
