On August 28, 2022, I learned from Caizhao.com that the bid-winning candidates for the Dujiangyan-Siguniangshan Mountain Rail Transit have been released. The project was won by Sichuan Highway and Bridge Construction Group Co., Ltd., with a bid price of 10.888 billion yuan.

Project Overview

The project starts from the Chengguan High-speed Railway Junction Station in Dujiangyan City and ends at Siguniangshan Town, Xiaojin County, Aba Prefecture. The total length of the line is 123.18 kilometers. The estimated total investment is 21.589 billion yuan, including 35.4 kilometers/25 new bridges and 85.7 kilometers of new tunnels. /25, with a bridge-to-tunnel ratio of 98.34%. There are 11 stations on the whole line, namely Dujiangyan Station, Yongfeng Station, Puyang Station, Longchi Station, Hongkou Station, Yingxiu Station, Gengda Station, Wolong Station, Dengshenggou Station, Balangshan Station, Siguniangshan Station .

The project is designed according to the mountain rail transit system, with passenger transport as the main function, and freight transport as well. The main line is a double line, the gauge is 1000 mm, the limited slope is 4% for the wheel-rail section, and the rack section is increased to 12%. The maximum driving speed is 120 km/h, and the rack section is 30 km/h. .
