The 292 kilometres (181 mi) long Second Chengdu–Chongqing high-speed railway will take a more direct route than the existing 307 kilometres (191 mi) long high-speed Chengdu–Chongqing intercity railway and is expected to reduce journey times between the two cities to 50 minutes.[4] In addition, the section between Jianzhou and Dazu Shike will be designed for 400 km/h (250 mph) operations in the future,[5] creating potential conditions for further reductions to travel time.
Approval for the 69.273 billion yuan project was granted on August 17, 2021 by the National Development and Reform Commission.[1] Later the project cost was revised to 73.3 billion yuan.[5] Construction started on September 26, 2021.[4]
The first railway between the two cities was the Chengdu–Chongqing railway, completed in the 1950s.[8] The Suining–Chengdu railway and Suining–Chongqing railway form a route between the two cities which was completed in 2006. The fastest journeys on this line take just over two hours. The Chengdu–Chongqing intercity railway was completed in 2015.
