CRRC Zhuzhou, a subsidiary of China Railway Rolling Stock Corp－the country's largest rolling stock manufacturer by production volume－said this is a breakthrough in China's heavy haul railway sector and a milestone in the country's self-innovation in equipment manufacturing.

CRRC has built a global network of 75 subsidiaries from Malaysia to as far as South Africa, including 13 research and development centers located in the United Kingdom, the United States and Germany.

CRBC has managed to find partners from Croatia and other European countries. Croatian multinational oil company INA provides diesel for the project, Croatia-based building material provider PGM is responsible for 70,000 cubic meters of concrete, maritime service company Marine Construct specializes in geological survey, and Slovenian company SLP offers pile testing and monitoring experts. Some reinforcement bars are purchased from a steel plant in Bosnia and Herzegovina, while an Italian factory sells the thicker version of them.

CRSBG's contributions strengthen the world's infrastructure projects across industries
