Chengdu–Chongqing intercity railway

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 line includes four major elevated sections and two tunnels.

For the planned railway, see Chengdu–Chongqing high-speed railway.

History

Construction on the Chongqing section began on 22 March 2010 while work on the Sichuan section began on 11 November. The final tunnel achieved breakthrough on 16 December 2013 and a single track line was expected to open in first half of 2014. The complete double track configuration was due to be completed by the end of 2014.[1] The line started operation on 26 December 2015,[2] initially to Chongqing North until renovations were completed at Shapingba on the 25th of January, 2018.[3]

Journey time

The railway reduced travel time between Chengdu and Chongqing to 75 minutes, 45 minutes quicker than the previous fastest route via Suining.[4] Travel time was reduced further to only one hour on December 24, 2020 with the introduction of Fuxing trains and 350 km/h (220 mph) operations on the line.[5][6]

An additional line is planned which will offer a faster journey time when complete, the Chengdu–Chongqing high-speed railway.
