China poised to open 350 km/h automated railway



Automated operations are due to start before the end of this year on the 174 km high speed line linking Beijing with Zhangjiakou in Hebei province, one of the host cities for the 2022 Winter Olympic Games. Journey times will be cut to around 50 min compared with about 3 h by trains using the 190 km conventional line.

Designed to carry visitors to the Olympic venue at up to 350 km/h, the line will be ‘the smartest in the country’, according to Mo Zhisong, Chief Engineer responsible for train control systems at China State Railway Group, which until June this year was known as China Railway Corp.

Speaking at a press event last month, Mo said tests had shown that the smart railway improved operational safety and comfort, enhanced on-time performance and cut energy costs. Automatic driving and dispatching systems and intelligent substations are among 67 ‘smart technology projects’ deployed on the line. Different types of intelligent robot will be available at stations to assist passengers and handle luggage. During the trials, a test train reached a maximum speed of 385 km/h.

Design of the 53·5bn yuan railway was carried out by China Railway Engineering Consulting Group with the help of a suite of software from Bentley Systems. The line includes 10 tunnels, one of which is 1·2 km long, and 64 bridges. One of the 10 stations will serve the Great Wall visitor site at Badaling and is located up to 102 m below the surface.
