China has revealed a prototype for a new high-speed Maglev train that is capable of reaching speeds of 620 kilometres 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-metre-long prototype was unveiled to media in the city of Chengdu, Sichuan Province, on January 13. In addition, university researchers constructed 165 metres of track to demonstrate how the train would look and feel in transit, according to state-run Xinhua News.

Professor He Chuan (vice president of Southwest Jiaotong University, which worked on the prototype) told reporters that the train could be "operational" within 3-10 years.

He added: "Sichuan has rich rare earth resources, which is very beneficial to our construction of permanent magnet tracks, thus promoting the faster development of experiments."

China is home to the world's largest high-speed rail network, which stretches over 37,000 kilometres, and the fastest commercially operating train -- the Shanghai maglev.

The country's first high-speed Maglev train, it began operating in 2003. Running at a top speed of 431 kph, the train links Shanghai Pudong Airport and Longyang Road in the eastern side of Shanghai.

China has been eager to make further infrastructure improvements ahead of the 2022 Winter Olympics, which will take place in Beijing.

This time last year, China unveiled a new 174-kilometre high-speed railway line connecting Beijing with 2022 Winter Olympics host city Zhangjiakou, cutting the travel time between the two from three hours to 47 minutes.

Earlier this month, the country debuted a bullet train specifically designed to withstand freezing temperatures. The CR400AF-G train can travel up to 350 kilometres per hour in weather as cold as -40 degrees Celsius (-40 degrees Fahrenheit).

It will run on routes between Beijing, Shenyang and Harbin -- the latter of which is so cold that it hosts an annual snow and ice festival.
