The Sichuan–Guizhou Railway or Chuanqian Railway (simplified Chinese: 川黔铁路; traditional Chinese: 川黔鐵路; pinyin: chuānqiǎn tiělù), is a single-track electrified railroad in southwest China between Chongqing Municipality and Guiyang, Guizhou Province. The shorthand name for the line, Chuanqian, is derived from the shorthand names of Sichuan Province (Chuan 川), to which Chongqing once belonged, and Guizhou (Qian 黔).
The Sichuan–Guizhou Railway originates in the north from the Chongqing Railway Station and shares tracks with the Chengdu–Chongqing Railway to Xiaonanhai. The line crosses the Yangtze River via the Baishatuo Railway Bridge and passes through Qijiang before entering northern Guizhou. The Liangfengya Tunnel 4,270 m (14,009 ft) on the Chuanqian Line in Tongzi was the longest railway tunnel in China when it was built.
