The 700 km line, part of the Beijing-Kunming corridor, runs from Chongqing West via Sichuan and Guizhou to Kunming South at a design speed of 350 km/h. The Chongqing-Yibin section opened in September 2024; the Yibin-Kunming section now moves to static acceptance and joint testing, with service expected in the first half of 2027. [2] [3]

Once operational, Chongqing-Kunming travel time will be cut to about two-and-a-half hours and Chengdu-Kunming to under three hours. [2] [3]
