Rail engineer trials automatic track laying system in China

China Railway Engineering (CRE) has debuted a smart track-laying method on a 500m stretch of a high-speed rail line in Hunan Province, which it claims can cut site labour by some 63%. CTCE is a subsidiary of China Railway Group. China Daily reports that the system uses a “long-rail intelligent sorting vehicle”, a push-and-roller recovery vehicle and a tractor. Called “WPZ-500”, the system was developed with the assistance of Central South University based in Changsha, Hunan province, and Zhuzhou Xuyang Electromechanical Technology Development.
