The highest speed is 385 kilometers per hour! Beijing-Zhangzhou High-speed Railway has been commissioned jointly

At 14:18 on October 5th, with the opening of the first comprehensive inspection vehicle, the 55201 train from Beijing Zhangjiakou high-speed railway, the Beijing Zhangjiakou high-speed rail joint commissioning work was officially launched, and the opening of the Beijing Zhang Gaotie railway and the Guangzhou railway entered the countdown.

Jing Zhang high-speed rail

Beijing Zhangjiakou high-speed railway starts from the airport, passes through the railway station, stops, stops, stops, and ends. The main line of Beijing Zhangjiakou high-speed rail is 174 km long, of which 70.5 km in Beijing and 103.5 km in Hebei Province, with a maximum design speed of 350 km / h. The joint commissioning test was carried out by using CRH380AJ-0203 EMU to carry out the step by step speed test between the two blocks. In the process of step-by-step speed increase, the maximum speed of each section of the test train should not exceed 110% of the allowable speed of the section line. Therefore, the maximum test speed is expected to reach 385 kilometers per hour during the joint commissioning test period.

According to the relevant person in charge of Beijing-Zhang Intercity Railway Co., Ltd., the joint commissioning and commissioning work is organized by the operation unit, the Chinese Academy of Railway Sciences carries out the inspection, and the construction unit and the integration unit jointly participate in the completion. In order to ensure the safe and smooth operation of EMU trains, the joint commissioning is a rigorous test, test and adjustment optimization before the opening of high-speed railway.

After the static acceptance of the new line project is qualified, the railway department verifies the performance of the track, power supply, catenary, communication, signal, early warning and monitoring system by means of comprehensive detection of train dynamic detection; evaluates whether the comprehensive grounding, electromagnetic environment, vibration and noise data meet the standards, so as to make the performance of each system and the whole system meet the design requirements, and provides important technology for operation. Guarantee.

Beijing Zhangjiakou high-speed rail is an important part of the "Beijing eight Gorges" channel in the national medium and long term railway network planning. It is an important foundation project for the coordinated development of Beijing, Tianjin and Hebei. It is also an important traffic guarantee facility for the 2022 Winter Olympics.

After opening and running, the high speed rail arrived from 1 to 12 hours.
