The Second Chengdu–Chongqing high-speed railway is a 292km (181miles) long high-speed rail line that connects the cities of Chengdu (in Sichuan Province) and Chongqing in southwestern China, with a maximum speed of 350km/h and a future design speed of 400km/h.[1] [2] It will head via Lezhi, Anyue, and Dazu. Construction started on September 26, 2021 [3] and it is expected to open in 2027.
The 292km (181miles) long Second Chengdu–Chongqing high-speed railway will take a more direct route than the existing 307km (191miles) long high-speed Chengdu–Chongqing intercity railway and is expected to reduce journey times between the two cities to 50 minutes. In addition, the section between Jianzhou and Dazu Shike will be designed for 400km/h operations in the future,[4] 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.[5] Later the project cost was revised to 73.3 billion yuan. Construction started on September 26, 2021.

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.
