The arrival of a new chapter in people's life in northern Shanxi!

On September 13, the joint commissioning and trial operation of Dazhang high-speed railway started in full swing, and the first high-speed railway line in northern Shanxi entered the countdown of operation. The

high-speed railway connects Datong in Shanxi Province in the West and Zhangjiakou in Hebei Province in the East. It is a double track passenger dedicated line with a total length of 134.4km and a design speed of 250km / h. There are three stations in Datong south, yanggaonan and Tianzhen. The construction of a 6031 a 6031 high-speed railway started in November 2015, and is expected to open simultaneously with Beijing Zhangjiakou high-speed railway and Zhangjiakou Hukou high-speed railway at the end of this year. Connecting with Beijing Zhangjiakou high speed railway, it is a fast passenger transport channel connecting Shanxi and Shaanxi to the west of Inner Mongolia and the north of Hebei. It is of great significance to improve the high-speed passenger transport network in North China, serve the Great Wall Golden Triangle Economic Cooperation Zone of Mongolia, Shanxi and Hebei (wuzhangda), help "Beijing Tianjin Hebei integration" and "Bohai sea cooperation development". The joint commissioning and joint test work will gradually test the equipment along the line, debug and optimize according to the test results, provide important technical support for the line operation, and is an important link to ensure the high standard and high quality operation of Dazhang high-speed railway. In the two-month joint commissioning and test, Taiyuan Bureau Group Co., Ltd. will conduct a comprehensive test on the interface and matching relationship between all systems of the line and relevant systems by using the test train, test EMU, comprehensive test train and relevant test equipment under the specified test speed. Through step-by-step speed-up test, signal system test and earthquake early warning monitoring system test, the performance or function of traction power supply, catenary, communication, signal, passenger service, disaster monitoring and other systems, the applicability of track, turnout, subgrade, bridge, tunnel and other structural works, and whether comprehensive grounding, electromagnetic environment, vibration and noise meet the standards are evaluated and verified. Ensure that the functions and performance of each system meet the design requirements and have the opening conditions.

in view of the large temperature difference between day and night in the areas along the Dazhou Zhangjiakou high speed railway, especially the severe weather such as low temperature, heavy snowfall and strong wind when it is put into operation in winter, Taiyuan Railway Bureau Group Co., Ltd. and Daxi Passenger Dedicated Railway Co., Ltd. jointly organize all participating units to strictly inspect the standards and timely modify and adjust them in accordance with the requirements of "ensuring the safe operation of EMUs". 。 Special theoretical and practical training shall be carried out for the staff and management personnel in charge of joint commissioning and test, and all stations and trains along the line shall be organized to complete the whole process simulation operation and emergency simulation drill. In order to solve the problem that the relevant units of Dazhou Zhangjiakou high speed railway contact the high speed railway for the first time, and all works are basically at zero start, Taiyuan Bureau Group Co., Ltd. has transferred experienced personnel of high speed railway to Dazhou Zhangjiakou high speed railway from the stations along the line of Daxi high speed railway to carry out mutual insurance between stations and sections. During the test, the whole process of monitoring, guidance, learning and communication are carried out. According to

, after the completion of the joint commissioning and test, the Dazhang high-speed railway will carry out the operation test. After passing the preliminary acceptance, safety assessment and conformity assessment, it can fully meet the operation conditions. After opening to traffic, it only takes about 40 minutes from Datong to Zhangjiakou, and the time from Datong to Beijing will be reduced from the current six hours to about 100 minutes. The road network structure of Shanxi Province and the people's travel life along the line will open a new chapter.

as the saying goes, "if you want to be rich, build a road first." The opening of Dazhang high-speed railway will promote the development of economy and tourism in the two places, and it will be a beautiful scenic spot in the railway industry.
