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. The line opened on August 15, 1961, and was electrified in 1975 and was the first to be electrified in the country. 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.
