On May 24, 166 "pink wagons" were shipped to Australia from Changshu Port in Jiangsu Province. This batch of vehicles was developed by the Zhuzhou Rolling Stock Co., Ltd. of CRRC Yangtze Group Co., Ltd. It was the third time for the company to customize products for the Roy Hill Company in Australia in recent years.

The rolling stocks are stainless steel open-top ore wagons, mainly used for transporting mineral powder and ore. With an axle weight of 40 tonnes, it is one of the largest axle weight general railroad wagons currently in operation. The exterior of the vehicle has been painted in pink, as per the customer's choice to support the "Pink Ribbon Breast Cancer Awareness Campaign" initiative. Upon arrival, there will be 438 pink wagons in operation in Australia, looking like flowing pink ribbons.
