With the
2022 Beijing Winter Olympics fast approaching, the world's first self-driving high-speed train is already in action, transporting athletes and officials between the
two main cities hosting the games on the
historic Beijing-Zhangjiakou intercity railway.
The fact that this
bullet train can drive itself is remarkable enough. But partway through the 56-minute ride, it passes through another engineering marvel:
the Badaling Great Wall Station.
