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)[1] 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).[2][3] It will head via Lezhi, Anyue, and Dazu. Construction started on September 26, 2021 [4] 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.[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.

History

[edit]

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]

Other railways between Chengdu and Chongqing

[edit]

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.
