The railway line links Beijing to Zhangjiakou in Hebei province, co-host city for the 2022 winter games. With a maximum design speed of 350 km/h, the travel time between Beijing and Zhangjiakou will be shortened from more than 3 hours to 47 minutes. There will be 10 stations, and some stations will have facial recognition devices that allow passengers to enter the gates with their personal IDs. The intelligent high-speed trains are upgrades of the Fuxing bullet train, able to achieve autonomous and intelligent driving covered by the Beidou satellite system. The trains have functions tailored for the 2022 Olympics, such as media cars that will livestream sports events, and racks for skis.
