Live: Beijing-Zhangjiakou high-speed railway in service

The 2022 Winter Olympics just got another major upgrade for athletes and spectators. A new, smart high-speed railway between Beijing and Zhangjiakou, host cities for the Games, starts operation on Monday. The railway will shorten the distance between the two cities to less than 50 minutes. Join CGTN's Sun Ye for a ride on the train and see if it's indeed running at the top speed (350km/h) it promised!
