Construction of the UHS maglev transportation system started in Yanggao County in April 2022. It integrates aerospace technology with ground railway transportation technology, aiming to achieve a train speed at 1,000 km per hour.

In the future, the system could be used for transportation between China's megacity clusters, allowing for a journey from Beijing to Shanghai in about an hour and a half.
