RRC’S QIQIHAR ROLLING STOCK Company, known as QRRS, is the core subsidiary for its operations in Qiqihar City, and the pillar enterprise in the freight wagon sector for CRRC. Over the last 20 years, QRRS has provided more than 17,000 wagons to Australia and New Zealand. Its range of ore wagons, grain hopper wagons, coal hopper wagons, container flat wagons, articulated wagons, side dumping wagons, ballast wagons, tank wagons and others has found success in the Pilbara region of Western Australia, along with the eastern states, South Australia, and on both South and North Island in New Zealand.

Operation speeds for the 40t wagons have been improved to 100km/h with a maximum traction tonnage of 57600t. “At present, the 40t axle load ore wagons developed and manufactured by QRRS are popular
