The Chenglan Railway Chengchuan section is located in Sichuan Province. The project is in line with the existing Baocheng Line in Qingbaijiang Station in Chengdu. It passes through Deyang, Mianyang to Aba, and is in line with the completion of the Xining Railway in Huangshengguan. The design speed is 200 kilometers per hour. It is about 275.8 kilometers long and is the first railway built on the plateau in Sichuan. According to Liu Chao, deputy chief engineer of the Chenglan Railway Headquarters of China Railway 19, the Yuelongmen Tunnel is a controlling project across the board and the division of the plain and the plateau. This year, the phenomenon of "seasonal wind" began to occur in the tunnel, which led to the increased harmful gases in the cave in a short time. Especially during the rail paving, the rail paving vehicle adopts diesel engines. If the ventilation is poor, a large amount of toxic and harmful gases may be generated. The employees of the project department adhere to the data to determine the data in the cave 24 hours, solve the ventilation problem. It is expected that the launch of the left line of the tunnel will be completed within this month, and the right line is completed within the year.

It is planned to complete all rail paving tasks except the Desheng Tunnel this year.
