Yanqing Branch Line of Beijing Zhangjiakou high speed railway enters countdown

On July 17, the communication and signal engineering of Yanqing Branch Line of Beijing Zhangjiakou high speed railway, which was undertaken by Beijing Branch of China Communications Engineering Bureau Group, passed the preliminary acceptance of China National Railway Corporation, marking a step closer to the opening and operation of the line. The total length of Yanqing Branch Line of Beijing Zhangjiakou high speed railway is 9.32km.

After the Yanqing Branch Line passed the dynamic acceptance on July 15, the State Railway Group organized relevant experts and units to conduct another inspection and acceptance on the construction of Yanqing Branch line, static and dynamic acceptance in the previous stage, problem rectification and implementation of expert review opinions. It is also the last "big test" before the opening and operation of Yanqing Branch line. Since the commencement of the project, the project Department of Yanqing Branch Line of China Communications Engineering Bureau Group has been playing steadily, attaching great importance to each project node, and promoting the project construction safely and orderly. Taking Beijing Zhangjiakou high speed railway as an example, they strengthened basic work, paid attention to detail management, improved security system, improved key and key process card control measures, improved construction quality and technology, and ensured the internal reality and external beauty of communication and signal engineering.
