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.
