A new maglev train prototype and 165 metres (540 feet) of test track were unveiled in Sichuan province in China on January 14, 2021.

It was developed by researchers at Southwest Jiaotong University, who said their “high-temperature superconducting maglev” technology is more economical and efficient since it uses liquid nitrogen as a coolant.

The train is designed to travel up to 620km/h (385mph), but developers are working to boost its speed to 800km/h (497mph).

A commercially viable version of the train could take another six years to create.
