The Chengdu–Chongqing intercity railway (simplified Chinese: 成渝客运专线; traditional Chinese: 成渝客運專線) is a 307-kilometre (191 mi) long high-speed railway that connects the cities of Chengdu (Sichuan) and Chongqing in southwestern China, with a maximum speed of 350 km/h (220 mph).

The route passes through most of the same cities that the older Chengdu–Chongqing Railway does, but is significantly shorter due to the greater use of elevated sections and tunnels.

The final tunnel achieved breakthrough on 16 December 2013 and a single track line was expected to open in first half of 2014.

[1] The line started operation on 26 December 2015,[2] initially to Chongqing North until renovations were completed at Shapingba on 25 January 2018.

[4] Travel time was reduced further to only one hour on 24 December 2020, with the introduction of Fuxing trains and 350 km/h (220 mph) operations on the line.
