The reporter learned from the China Railway Corporation that since July 2014, the railway department has successfully carried out a comprehensive test of 30 tons of axle load and heavy-duty railways between the eldest son of the south-south railway route in south and south of Pingshun, marking the achievement of China's heavy-duty railway technology. A new breakthrough.
Heavy-duty transportation is an internationally recognized development direction of railway freight transportation, and the axle weight of trucks represents the development level of railways. At present, China's railway wagons generally use 23 tons of axle load. In recent years, in order to speed up the development of heavy-duty transportation, the railway department has successfully developed a complete set of 25-ton axle-heavy and heavy-duty railway technology through independent innovation, and successfully applied it to heavy-duty lines such as the Daqin Railway. On this basis, combined with the implementation of the new Shanxi Central and Southern Railway Passage Project, the railway department carried out comprehensive research and development of 30 tons of axle load and heavy-duty railway technology, systematically organized core equipment and key technology research, and developed the 30-ton axle load locomotive for the first time, 30 Tung axle load trucks and electronically controlled air brake systems; the first phase of the development of the same phase power supply technology and energy-saving traction transformer; the first development and application of 30 tons of axle load heavy-duty railway track structure, heavy-duty rail and ballast and line bridge tunnel complete sets of technology.
This comprehensive test will lay a solid foundation for the opening of a 30-ton axle-heavy and heavy-duty railway in China. It will further enhance the technological innovation level of China's heavy-duty railways and form a complete technical system for 30-ton axle-heavy and heavy-duty railways with independent intellectual property rights.
