However, there are major technological problems to resolve before the train could be put in to use.

"For example, the train would need a vacuum tube that extends hundreds of kilometers. And it is challenging to maintain such a large vacuum system," Zhao said.

"Also, there could be external impacts like earthquakes that could pose a threat to the system. And the braking system of the train at such high speed also needs non-traditional designs."
