World's first Autonomous Rail Rapid Transit system, or ART, on Tuesday officially entered a trial operation phase that will last for three months in Zhuzhou in Central China's Hunan province.

This shows the capability of China Railway Rolling Stock Corp of commercializing its independently developed ART system since its debut in October 2017.

The smart bus, developed by the research arm of CRRC Zhuzhou Locomotive Co Ltd, is about 30 meters long and equipped with sensors that can read the dimensions of roads and plan its route. It has a maximum speed of 70 kilometers per hour.

The 3-kilometer A1 test line has set up four stops. Passengers can scan a QR code to receive an electric ticket and take a ride.
