CRRC Nanjing Puzhen Rolling Stock, a subsidiary of Chinese rail manufacturer CRRC, has rolled out the first fully automated metro train for the network in Hangzhou, a major city in eastern China.
The train will enter service on Line 12 of the Hangzhou Metro and is designed for a maximum operating speed of 100 km/h. The train was developed according to the local AH-type specification, used for the city’s metro system.
According to CRRC, the train can automate the entire operational cycle, from start-up and shutdown to self-diagnosis, entering and exiting the depot, running on the line, stopping at stations, door operation, and automatic washing.
Intelligent systems for driverless operation
The train is equipped with on-board intelligent systems, including active and passive obstacle detection and monitoring of bogie and running gear safety. Critical circuits and subsystems have been designed with redundancy to enhance operational safety.
The train also features self-healing functions, such as automatic resetting of certain subsystems and remote control, to maintain availability in the event of abnormal situations.
Energy consumption reduced by over 20%
The train uses a permanent magnet traction system, which enables a total energy savings of over 20%, according to the manufacturer.
For passenger comfort, the air conditioning system includes antibacterial and antiviral purification functions, combined with intelligent airflow distribution.
CRRC also notes that the train uses airtight electric doors, soundproofing materials, and solutions to reduce vibrations and noise.
