The Hunan–Guangxi Railway or Xianggui Railway (simplified Chinese: 湘桂铁路; traditional Chinese: 湘桂鐵路; pinyin: xiāngguì tiělù), is a single-track electrified railroad in southern China that connects Hunan province and the Guangxi Zhuang Autonomous Region. The shortform name of the line, Xianggui, is named after the Chinese shorthand names of Hunan, Xiang and Guangxi, Gui. The line runs 1,013 km (629 mi) from Hengyang in Hunan to Friendship Pass on Guangxi's border with Vietnam.[1] The line was built in sections from 1937-1939 and 1950-1955. Major cities along route include Hengyang, Yongzhou, Guilin, Liuzhou, Nanning, Pingxiang and Friendship Pass. In December 2008, construction began on a capacity-expansion project for the Hunan-Guangxi Railway.[2] The project is adding 723.7 km (450 mi) of new electrified double-track along the entire route, including 497.9 km (309 mi) between Hengyang and Liuzhou and 225.8 km (140 mi) of passenger-dedicated line between Liuzhou and Nanning.[3]
