On December 30, Beijing-Zhangjiakou HSR (including Chongli Railway) was officially put into operation. The debut of the first intelligent EMU on this HSR attracted attention of people from all walks of life and brought a unique travel experience to the passengers.


Beijing-Zhangjiakou HSR runs from Beijing North Station to Zhangjiakou Station. It passes through Beijing and Hebei Province. Its main line has 10 stations, including Beijing North, Qinghe, Shahe, Changping, Badaling Great Wall, Donghuayuan North, Huailai, Xiahuayuan North, Xuanhua North and Zhangjiakou. Yanqing Station is set for Yanqing Branch Line and Taizicheng Station is set for Chongli Railway. Beijing-Zhangjiakou HSR is 173.96km long totally.


It is an important part of Beijing-Lanzhou Corridor in the HSR network composed of "eight north-south lines and eight east-west lines" specified in China's Medium- and Long-term Railway Network Plan. The HSR is connected to Zhangjiakou-Hohhot HSR and Zhangjiakou-Datong HSR in the west, both of which were put into operation on the same day. It is connected to Beijing Terminal in the east, providing a fast passenger transport corridor between eastern Inner Mongolia, northern Shanxi, northern Hebei and Beijing.


At 8:30 on this day, train G8811 departed from Beijing North Station on schedule, heading for Taizicheng, as the first train running on Beijing-Zhangjiakou HSR. The outstanding feature of this Fuxing CR400BF-C EMU is "intelligent", including intelligent train operation, intelligent service, and intelligent operation and maintenance.


The CR400BF-C intelligent EMU is the world's first train running at a speed up to 350km/h in commercial automatic operation with a driver onboard. The CTCS-3 + ATO technology enables a series of operations such as automatic departure from stations, automatic in-section operation, automatic stopping at stations, automatic opening of doors, and linkage control of train doors and platform doors. The train has an automatic speed control precision within 2km/h and a stopping precision within 0.5m.


The intelligent automatic operation of the CR400BF-C intelligent EMU also includes the environment perception + decision-making function. The automatic operation system collects and processes environmental information (such as geographic location and route information) and vehicle status with the devices including on-board sensor, radar and antenna, and combines them with the EMU status. At the same time, it presets the algorithm for the purpose of safety, stability and comfort, and makes decisions in light of speed limit requirements and so on. The automatic operation of CR400BF-C intelligent EMU is not the operation just at preset time and speed. On the contrary, it simulates thinking of a human driver according to the actual conditions and adjusts operation at any time, so it is truly intelligent.


Different from the previous EMU versions, the CR400BF-C intelligent EMU is the first high speed train tailored to a line in China. From the exterior and interior, we can see some special designs for Beijing-Zhangjiakou HSR. Its attentiveness enhances travel experience here and there.


In addition to the optimized train head, the CR400BF-C intelligent EMU is equipped with the cold-proof technology suitable for the -40°C operation environment. The performance of traction and braking systems are improved to meet the requirements of starting and safe stopping at 30‰ grade to enable the train to run in mountainous areas. In particular, the new power battery system can drive the train to travel 20km at a speed of 30km/h in case of a power supply failure of the OCS, and so the train is able to move to the nearest station in case of a power supply failure in any section of Beijing-Zhangjiakou HSR. Now passengers no longer need to worry about being stuck halfway in the train due to OCS failure.


In terms of the interior, in addition to the intelligent environment adjustment and intelligent information exchange systems mentioned above, in order to improve the riding experience, the business-class seats of CR400BF-C intelligent EMU are designed to be more aesthetic and ergonomic, and so more comfortable.


In 1909, Beijing-Zhangjiakou Railway, the first railway independently built by China, was completed. It starts from Beijing, and passes through Badaling to Zhangjiakou in Hebei Province. In order to enable trains to climb up the steep hillside, Zhan Tianyou, the chief engineer, designed a herringbone turn-round track along the mountain. This is an innovation in the Chinese railway history.


110 years later, trains run underground from Qinglongqiao Station near Badaling Great Wall. In the long course of history, the new and old Beijing-Zhangjiakou railways "meet together" in the Winter Olympics Era.


In the future, with the continuous development of Chinese HSRs, undoubtedly more progress will be made in intelligent high speed EMUs.
