Recently, trains developed by CRRC for the Chengdu Metro Line 13 Phase I and Line 30 Phase I were put into operation, marking a new era of more intelligent and autonomous operations in the city.
Thanks to the GoA4-level fully automated system, the Line 13 trains automatically wake up and complete self-checks before daily service, depart on schedule, and return to the depot after operations are completed, without any human intervention throughout the entire process.
Line 30 is China’s first subway line to integrate conventional fully automated operation and train-to-train communication technology. Through direct interaction between trains, the technology can significantly reduce headways while improving operational efficiency and safety redundancy. Equipped with advanced autonomous computing and route-planning capabilities, the line operates at GoA4, the highest level of automation.
Both lines are equipped with CRRC SRI's Internet of Vehicles (IoV)-based Prognostics and Health Management (PHM) system, and, for the first time, feature visualized train fault diagnosis and emergency response functions. For the critical faults, visual models of fault tree analysis and emergency response procedures are established to track the entire process of fault handling and intelligently assess the compliance.
