So what makes them “smart”? Well, the train cars     4     (equip) with 5G signals, intelligent lighting and sensors to collect real-time data and detect any operational abnormalities. Meanwhile, each individual seat has     5     (it) own touch-screen control panel and wireless charging docks. Though the high-speed trains on the route are autonomous, a monitoring driver will be on board at all times. The trains can start, stop and adjust automatically     6     different speed limits between stations. Back at the station, robots and technologies of facial     7     (recognize) can help passengers with directions, luggage and paperless check-ins.

Today, China is home to the world’s     8     (large) high-speed rail network, and the fastest    9     (commercial) operating train — the Shanghai maglev.
