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.
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.
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.
Baoji-chengdu railway starts from Baoji in Shaanxi in the north, reaches Chengdu in Sichuan in the south, passes through Shaanxi, Gansu and Sichuan provinces, and is connected with chengdu-chongqing railway, chengdu-kunming railway, Longhai Railway and Baozhong Railway, with a total length of 669 kilometers.

After the completion of the railway, due to the large slope and many tunnels, the electrification transformation was carried out. The first phase of 9 1 km electrification from Baoji to Fengzhou was completed on 196 1, and the whole line electrification was completed on 1975. This is the first electrified railway in China.
Baoji-chengdu railway is bounded by Guangyuan Station, Baoji-Guangyuan section is under the jurisdiction of Xi Railway Bureau, and Guangyuan-Chengdu section is under the jurisdiction of Chengdu Railway Bureau. The list of radio stations is arranged by geographical area.

Baoji-chengdu railway project is arduous, and the main quantities of the whole project are: subgrade earthwork 765,438+065,438+060,000 cubic meters; 304 tunnels with a total length of 84.4 kilometers; Bridge 100 1 seat, with total length of 28. 1 km; The total length of the bridge and tunnel accounts for about 17% of the line length, and the main line is 667.7438+0 km. From construction to commissioning, there were 58 serious landslides and 272 collapses, and the amount and difficulty of remediation were quite large.
The completion of Baocheng electrified railway has opened the process of railway modernization in China. Since then, with the pace of economic construction and reform and opening up in the motherland, electrified railways have entered a period of rapid development. In just over 20 years, it has become the ninth country with an electrified railway of 10,000 kilometers after Russia, Germany, Japan and other countries. This achievement is inseparable from the fact that baoji-chengdu railway has trained and trained a large number of construction backbones.
Baoji-chengdu railway is mainly responsible for the exchange of materials between southwest and northwest regions, and is the backbone of the national railway network, which has played a great role in the development of industrial and agricultural economy along the line. Later, four branch lines were built from Guangyuan to Bazhong, Deyang to Hanwang, Guanghan to Yuejiashan and Qingbaijiang to Dujiangyan, which promoted the development of mineral resources in nearby areas.
