The Second Chengdu–Chongqing high-speed railway (Chinese: 成渝中线高铁; lit. 'Chengdu–Chongqing Central line high-speed railway') is a 292-kilometre (181 mi) long high-speed rail line that connects the cities of Chengdu (in Sichuan Province) and Chongqing in southwestern China, with a maximum speed of 350 km/h (220 mph) and a future design speed of 400 km/h (250 mph). It will head via Lezhi, Anyue, and Dazu. Construction started on September 26, 2021 and it is expected to open in 2027.

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. In addition, the section between Jianzhou and Dazu Shike will be designed for 400 km/h (250 mph) operations in the future, creating potential conditions for further reductions to travel time.

History

Approval for the 69.273 billion yuan project was granted on August 17, 2021 by the National Development and Reform Commission. Later the project cost was revised to 73.3 billion yuan. Construction started on September 26, 2021.
