On June 19, 2021, the National Energy Group Heavy Haul Railway Mobile Blocking Technology Conference and Opening Ceremony was held in Shijiazhuang. The National Energy Group Shuohuang Railway became China’s first heavy-haul railway with a mobile blocking system, marking my country’s heavy haul Major breakthroughs in railway technology have been achieved.

Mobile block is recognized by international railways as the best control system for improving safety indicators and improving transportation efficiency. By controlling the safe interval time of multiple trains on the same railway, the occurrence of rear-end collisions of trains is prevented. For the first time, Shuohuang Railway proposed and adopted mobile blocking for technological upgrading and transformation, to further overcome the bottleneck constraints of transportation capacity, improve transportation efficiency, reduce logistics costs, accelerate the adjustment of transportation structure, promote "revolution to railway", and achieve high-quality development of transportation.

Shuohuang Railway's heavy-load mobile block system, after eight years of key technology research, core equipment development and equipment research, expanded testing and engineering application research, has realized a heavy-load mobile block system that meets my country's actual operational needs and is oriented to heavy-load railways. The "four innovations" of mobile block safety protection technology for complex scenarios, heavy-duty train relocation technology based on wireless communication and Beidou satellites, and comprehensive safety assurance technology for the entire process of heavy-load mobile blockage, are the capacity and efficiency of heavy-haul railways. Upgrade provides a complete set of solutions. The application of mobile block system technology can reduce the average departure interval of a truck from the original 11 minutes to 7.3 minutes. After the completion of the mobile block transformation on the Shuohuang Railway, the annual transportation volume can increase by 40 million tons, which can reduce the comprehensive maintenance cost of signal system equipment. 20%, it also has a positive effect on reducing the safety pressure of traffic personnel and the labor intensity of maintenance personnel.

The successful opening of the Shuohuang Railway Mobile Blocking System has filled the gap in the field of domestic heavy-haul railway mobile blocking technology, can greatly improve the automation level of heavy-haul transportation, and has a demonstrative and leading role in the expansion and promotion of my country's existing railways. At the same time, with the application of heavy-load mobile blocking technology, the significant advantages of railways such as green environmental protection, energy saving and high efficiency will be effectively brought into play, which will further promote the national transportation and local economic and social development along the railway, and help win the "blue sky defense war."Editor/Xing Wentao
