Line description

The Baocheng Line runs from the plains of the Sichuan Basin to the Wei River Valley. It traverses the Qin Mountains, the east–west range that divides northern from southern China. The line has 304 tunnels and 1,001 bridges, which collectively account for 17% of the total track length.^[1]

In Baoji, the line meets the Longhai railway, on which trains can travel east to Xi'an and the Central Plains or west to Lanzhou and the northwest. At Yangpingguan, the line intersects with the Yangpingguan–Ankang railway which branches eastward along the Han River Valley. In Chengdu, the line connects with the Chengyu Line to Chongqing, Chengqian Line to Guizhou, and Chengkun Line to Kunming.

History

The Baocheng line was originally proposed in Sun Yat-sen's 1913 China National railway plan as part of the Datong–Chengdu railway. Construction began in Chengdu on July 1, 1952 and from Baoji in January 1954.^[1] The line opened on January 1, 1958.^[2] The Baoji–Fengzhou section electrified in 1961, becoming the first railway to be electrified in the country.^[2] The entire line was electrified in 1971.^[2] Construction of a second track between Chengdu and Yangpingguan began in 1993 and was completed in 1999. From Yangpingguan to Baoji, the line remains single-track. The railway was badly damaged by the 2008 Sichuan earthquake.^[2]

The Baoji–Chengdu railway, together with the Xi'an–Baoji section of the Longhai railway, formed the main railway route between Xi'an and Chengdu (and, in general, between North China and Sichuan). However, the new Xi'an–Chengdu high-speed railway, between these two cities has assumed much of the passenger traffic on this route.
