Shanhaiguan is the main traffic route from the northeast into the Central Plains, and now there are two high-speed railways in Beijing-Harbin and Qinshen. Qin Shenke was opened in 2013 to connect the Beijing-Shanghai high-speed railway to East China in Tianjin; the Beijing-Harbin high-speed railway opened in early 2020, the main line only to Beijing Chaoyang Station, northeast to South China, the problem has not been completely solved, because now the starting point of the Beijing-Guangzhou high-speed rail is Beijing West Railway Station.
In theory, the Beijing-Harbin high-speed railway can also run to the Beijing-Guangzhou high-speed railway, from Beijing Chaoyang Station, via the East Star Liaison Line, beijing-Harbin railway, to Beijing Station Beijing-Shanghai field, through the underground diameter line, to the Beijing West Railway Station high-speed field. But on this road, there are three bottlenecks.
First, the Dongxing Liaison Line between Beijing Chaoyang Station and the Beijing-Harbin Railway is a single line with limited capacity.
Second, beijing station only has the Beijing-Shanghai field access to the underground diameter line, and the train needs to cut the main line of the Beijing-Harbin Railway, but it is not conducive to the busy Beijing-Harbin Railway operation.
Third, only the north side of the Beijing West Railway Station is connected to the underground diameter line, while the train has to go to the high-speed field on the south side to get on the Beijing-Guangzhou high-speed railway, and it also needs to cut the main line of the Beijing-Kowloon Railway.
The train cut the positive line twice, which is very troublesome for the organization of the train. Therefore, the underground diameter line in Beijing cost 2 billion yuan and took 8 years to complete and open to traffic, but it seems very chicken ribs, and after so many years of opening, only suburban railway trains are used. The biggest problem is that the design of the underground diameter line was not perfect, and all the stock channels of Beijing Railway Station and Beijing West Railway Station should be fully connected, and the current situation seems to have saved funds, but in fact, the utilization rate has not been achieved and has not played an effect.
After the opening of Beijing Fengtai Station at the end of 2021, all the ordinary speed trains of the Beijing-Shanghai and Beijing-Kowloon Railways will be relocated to Fengtai Station, Beijing Station will free up space for Beijing-Shanghai Yard, and Beijing West Railway Station will free up space for the Beijing-Kowloon Line, which can provide support for the opening of trains from Northeast to South China.
Some friends also said that the road from Beijing Chaoyang Station to Beijing West Railway Station belongs to the liaison line, and the design speed is low and very time-consuming. According to the maintenance requirements of the high-speed rail one-way no more than 2700 kilometers, Harbin can only go to Wuhan at the farthest, according to the current Harbin to Beijing Chaoyang 4 hours, Beijing west to Wuhan 5 hours, the whole process will reach 10 hours, such a long time, it is better to take a plane.
Friends, do you think it is necessary to open a high-speed railway in the northeast that passes south through Beijing? Feel free to share your thoughts in the comments section below.
