Wuhan, capital of Hubei province, is testing its first self-driving subway at the highest level of automation.

As a grade-of-automation 4 system, trains running on Subway Line 5 will operate automatically at all times, including opening and closing doors, detecting obstacles and handling emergencies.

They will not require operating personnel.

Due to the cancellation of the traditional driving cab, passengers can see the train moving at full speed in the front, which may greatly improve passengers' subway experience.
