Recently, the Changshui Airport Station on the Chongqing-Kunming High Speed Railway, built by China Railway 18th Bureau, completed related structural works, laying a solid foundation for the full operation of the line. As Yunnan Province's first high-speed railway designed for speeds of up to 350 km/h, the Chongqing-Kunming High Speed Railway serves as a vital transportation corridor connecting Yunnan, Guizhou, Sichuan and Chongqing.
