The ShanghaiâÂÂKunming Railway or Hukun Railway (), also known as the Hukun Line, is a major arterial railroad across eastern, south central and southwest China. It connects Shanghai, whose shorthand name is Hu, and Kunming. The line has a total length of and passes through Shanghai Municipality, Zhejiang, Jiangxi, Hunan, Guizhou and Yunnan Province. Major cities along route include Shanghai, Jiaxing, Hangzhou, Yiwu, Jinhua, Shangrao, Yingtan, Pingxiang, Zhuzhou, Huaihua, Kaili, Guiyang, Anshun, Qujing, and Kunming.
The Hukun Line is double track from Shanghai's South Station to Liupanshui and single-track railway for about from Liupanshui to Kunming. The speed limit for the line is from Shanghai to Zhuzhou and from Zhuzhou to Huaihua. The entire line is electrified.
The ShanghaiâÂÂKunming high-speed railway runs parallel to the ShanghaiâÂÂKunming Railway.
The ShanghaiâÂÂKunming Railway has four major segments, which were built over a span of 70 years. In 2006, after the Ministry of Railways rebuilt sections along route and increased train travel speed, the four lines were collectively referred to as one.
On May 23, 2010 (UTC+8), a passenger train derailed after heavy rains caused mudslides on the Hukun Line in Jiangxi Province, killing 19 passengers and injuring 71.
