The Chengdu–Chongqing Intercity Railway (simplified Chinese: 成渝客运专线; traditional Chinese: 成渝客運專線) is a 307 kilometres (191 mi) long high-speed railway that will connect the cities of Chengdu (Sichuan) and Chongqing in southwestern China, with a planned maximum speed of 350 km/h. The route will pass through most of the same cities that the older Chengdu–Chongqing Railway does, but will be significantly shorter due to the greater use of elevated sections and tunnels. It is expected to reduce travel time between Chengdu and Chongqing to 75 minutes, 45 minutes quicker than the current CRH route via Suining. The line will include 4 major elevated sections and 2 tunnels.
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 the December 16th 2013 and a single track line is expected to open in first half of 2014. The complete double track configuration is due to be completed by the end of 2014.
