context_page_description: The Chengdu–Kunming railway or Chengkun railway, is a major trunkline railroad in southwestern China between Chengdu, the capital of Sichuan Province and Kunming, the capital of Yunnan Province. The line is 1,134 km long and traverses rugged terrain from the Sichuan Basin to the Yunnan-Guizhou Plateau. The line was built between 1958 and 1970. Major cities along route include Chengdu, Pengshan, Jiajiang, Emei, Ebian, Ganluo, Xide, Xichang, Dechang, Miyi and Panzhihua in Sichuan Province and Yuanmou, Lufeng, Anning and Kunming in Yunnan Province.
context_section_description: Planning of the Chengdu–Kunming railway began in 1952 with several routes under consideration.  The westernmost route over the most difficult terrain was selected in 1956.  Construction began in 1958 during the Great Leap Forward and expanded to full-scale in 1964.  In July 1970, the line was completed and entered into operation in January 1971.  The government published a pictorial in 1976 showing pictures of the construction and extreme terrain that required hundreds of tunnels and bridges. Building conditions were hazardous and 2,100 workers perished during the construction of the original line.  On August 30, 2000, the entire line was electrified.  Aside from Chengdu and Kunming, the line has a total of 122 stations.
