On April 17, Hangzhou Metro’s first fully automated metro train, developed by CRRC Nanjing Puzhen Rolling Stock Co., Ltd., rolled off the production line, marking a significant step forward in the city’s smart urban rail development.
Built to Hangzhou’s proprietary AH-type specification, the train will enter service on Hangzhou Metro Line 12 with a maximum operating speed of 100 km/h. It automates the full operational cycle, including wake-up, sleep, self-diagnostics, depot entry and exit, mainline operation, station stopping and door operation, and train washing. On-board intelligent systems include active and passive obstacle detection and running gear safety monitoring. All critical circuits and subsystems adopt redundant design, significantly enhancing operational safety. In addition, it features self-healing capabilities, including automatic subsystem reset and remote control, ensuring high availability even under abnormal conditions.
Powered by a permanent magnet traction system, the train delivers an overall energy saving of over 20%. Its air conditioning system features antibacterial and antiviral purification, combined with intelligent airflow distribution technology for enhanced passenger comfort. High-seal electric plug doors, sound-insulating pads, and high-performance sound insulation materials are applied to further reduce vibration and noise.
