Abstract:: Over the past 40 years of Reform and Opening up, China has been vigorously developing heavyhaul railway in order to meet the needs of the growing national economy and has made significant achievements. In the past 40 years, the maximum traction weight of Chinese heavyhaul railway has been improved from 3500 tons to 30000 tons. Transportation lines of heavyhaul railway were transformed from expansion of existing lines to building new ones such as DatongQinhuangdao railway, BaotouShenmu railway, ShenmuShuozhou railway, ShuozhouHuanghua railway, Chinese first 30ton axleload lineShanxi’s MidSouth region railway, and the longest special coal transportation lineInner MongoliaJiangxi railway, which is currently under construction. Upholding the concept of “railway construction leads to a stronger transportation country”, the railway technicians have been upgrading and optimizing heavyhaul technology. Nowadays, China has owned a complete set of mature technologies and standard system for 25 tons and 27 tons axleload heavyhaul railways, and has developed distinctive 30 tons axleload heavyhaul railway technologies. In this article, the world’s heavyhaul railways are outlined, and the capacity expansion of existing heavyhaul railways of China in the 1980s are highlighted, with a focus on summarizing several major heavyhaul transport corridors that have been given great efforts, which played an important role and have made great achievements in the past 40 years of Reform and Opening up, and the longterm challenges facing heavyhaul railway technology. It also highlighted significant progress and technological achievements in locomotive, wagon, track, control and communication industries. Then, it commented on international cooperation and communications as well as related major awardwinning achievements in heavyhaul transportation. Finally, combined with the development trend of world’s heavyhaul technologies and the current situation of Chinese railway technologies, the main development trend and directions of heavyhaul railways in China are discussed, such as big axel load heavyhaul railway technology, multimodal transport technology, fast heavy haul technology and clean, intelligent and interconnected development.
