The total length of the railway is 213 kilometers, including 104 kilometers in Chuxiong Prefecture. The vast railway capacity expansion and transformation project is an important part of the Pan-Asian Railway West Line and Yunnan-Tibet Railway. It is a national grade I double-track railway with a total length of 174.45 km. The total length of bridges and tunnels is 109.88 km, accounting for 63% of the total length of the railway. The design speed of the railway is 200 km/h, and the estimated investment is 13.936 billion yuan. After the completion of the project, Kunming-Chuxiong inter-city train will run for only one hour, which is of great significance for strengthening the transportation capacity of the railway network in Western Yunnan and improving the Pan-Asian railway network.
