Will the opening of Xicheng high-speed railway have an impact on baoji-chengdu railway?

Baoji-chengdu railway starts from Baoji, Shaanxi Province in the north, crosses the Qinling Mountains in the south, and reaches Chengdu, Sichuan Province, a land of abundance, with a total length of 669 kilometers. The main cities along the route are Baoji, Guangyuan, Mianyang, Deyang and Chengdu.

The train runs on Baocheng Line.

Baoji-chengdu railway crossed the Weihe River from Baoji Station to the south, after a 27-kilometer exhibition line, climbed 680 meters through the Qinling Tunnel, arrived at Qinling Station and descended along the Jialing River. After passing through Gansu Province, it crossed the Daba Mountain area, continued to the southwest at Guangyuan Station, crossed Jianmen Mountain, entered Sichuan Basin, and arrived in Chengdu via Mianyang and Deyang.

Limited by the terrain, the section from Baoji to Yangpingguan in baoji-chengdu railway is a single-track railway, and the section from Yangpingguan to Chengdu is a double-track railway, which is a national first-class electrified railway trunk line.

Electrification section of Baocheng line

Baoji-chengdu railway is the traffic artery connecting the northwest and southwest regions, the first electrified railway in China and the first arduous railway in New China. The completion of this railway has changed the situation of "difficulty in entering Sichuan" and created important conditions for the development of economic construction in southwest China.

The train went through the tunnel.

Baoji-chengdu railway is built on the second step of our country, surrounded by mountains, criss-crossing rivers and dangerous terrain. Baoji-chengdu railway from Baoji Station to Jiangyou Station is almost always in the mountainous area. After starting from Baoji, you need to cross Qinling, Bashan and Jianmen Mountain successively. The terrain is dangerous, so the project is quite arduous. The whole baoji-chengdu railway project has crossed hundreds of mountains and filled hundreds of deep valleys. There are 60 million cubic meters of earth and stone filling alone. According to the height and width of 1 m, it can circle the equator of the earth for more than one and a half weeks.

Topographic map of Qinling area

After the railway entered the Qinling Mountains, it circled the Qingjiang River. When the railway crosses the Qinling Mountains, the straight-line distance from Yangjiawan Station to Qinling Tunnel is only 6 kilometers, but it has increased by 680 meters, that is, it has increased by 1 10 meters per kilometer. In order to change the slope to only 40 meters per kilometer, so that the train can pass, the railway line can only turn around repeatedly, with a straight line distance of 6 kilometers and 27 kilometers; The line between Renjiawan Station (formerly Baoji South Station, renamed as Renjiawan Station on 20 13) and Yangjiawan Station climbs rapidly with a gradient of 33‰.

A circuitous baoji-chengdu railway.

In order to overcome the altitude difference, after passing Yangjiawan Station, it circuitously ascends with three horseshoe-shaped spirals and1(Figure 8). The line has three layers, with a height difference of 8 17 meters, which is the famous Guanyinshan line, so you can see the overlapping scene of three layers of railways at Guanyinshan Station. When the train goes uphill, it needs three electric locomotives to pull forward and push back to reach Qinling Station. Braking all the way downhill, sparks everywhere, very spectacular. Then pass through the Qinling Mountain Pass, pass through the Qinling Tunnel with a length of more than 2,364 meters, that is, enter the Jialing River Basin and arrive at Qinling Station; After crossing the Qinling Mountains, the line goes down the Jialing River to Guangyuan, Sichuan, with a downhill slope of 12‰. The Qinling-Lueyang railway line crosses the Jialing River for 14 times.
