When will the Chengdu-Kunming double line be opened to traffic?
The Chengdu-Kunming double line is expected to be fully opened to traffic at the end of 2022 or 2023.
On December 9, 2019, the Yanbian Tunnel of the Chengdu-Kunming Railway double line was successfully completed, marking the completion of the Miyi to Panzhihua section of the Chengdu-Kunming Railway double line. On December 18, 2021, the Panzhihua South Station-Xichang West Station test run was carried out. On January 10, 2022, the Mianning to Miyi section of the Chengdu-Kunming Railway capacity expansion project was opened for operation. As of October 2022, only the section from Emei to Mianning is still under construction, and it is planned to be fully opened to traffic in 2022. By then, the double-track Chengdu-Kunming Railway will be separated from the old Chengdu-Kunming Railway passenger and freight lines, which can greatly enhance the passenger and freight transportation capacity of the southwest region's railways.
Characteristics of the Chengdu-Kunming double-track project
In order to ensure that the construction of the Chengdu-Kunming double-track project proceeds smoothly on schedule, the construction unit has overcome difficulties such as the narrow construction site, large height difference, and wide area for high-altitude and edge operations. In view of the complex geological conditions on site and the harsh weather conditions on the Western Sichuan Plateau, the construction process control and personnel management were strengthened, and a number of new construction techniques were adopted to properly solve various problems encountered during the construction.
The station building project of the Emian Section of the Chengdu-Kunming Railway Capacity Expansion and Renovation Project mainly includes 6 passenger stations including Shawan South, Emian South, Jinkou Henan, Ganluonan, Yuexi, Xidexi and Yan After the completion of the main structures of the five over-traffic stations including Gang, Fandianzi, Teke, Floodplain and Anluo and related production and living buildings, they will enter the sprint stage of beam erection and track laying. The outline of the Jinkou Henan Station is designed based on the local majestic valley elements, and the architectural colors are extracted from the traditional costumes of the local Yi people, highlighting the regional culture.
The double-track Chengdu-Kunming Railway is a new or additional railway line based on the existing Chengdu-Kunming Railway. It has a total length of more than 800 kilometers and is constructed and opened in sections. Currently, only the section from Emei to Mianning is still under construction, and it is planned to be fully opened to traffic in 2022. By then, the double-track Chengdu-Kunming Railway will be separated from the old Chengdu-Kunming Railway passenger and freight lines, which can greatly enhance the passenger and freight transportation capacity of the southwest railway.
