With a length of 189 kilometers and a design speed of 120 kilometers per hour, the Xubi section of the Longhuang Railway is a convenient railway passage from the Chengdu-Chongqing Economic Circle to northern Guizhou, Nanning and Beibu Gulf.
The line starts from Xuyong North Station in Xuyong County, Luzhou City, Sichuan Province in the north, passes through Zhenxiong County, Weixin County, Zhaotong City, Yunnan Province in the south, and reaches Bijie East Station in Bijie City, Guizhou Province, the overall altitude rises from 358 meters in the Sichuan Basin to 1573 meters in the hinterland of Wumeng Mountain in the Yunnan-Guizhou Plateau.
There are 8 bridges and 67 tunnels on the whole line, and the bridge-tunnel ratio reaches 86%. Since the start of construction in October 2016, the railway department has organized all participating units to innovate technology and construction methods to overcome difficulties and promote construction. The Fengjiazhai Bridge, which is the highest and spans of the whole line, has a pier of about 129 meters, which is equivalent to the height of a nearly 50-story building. 12.The 8-kilometre Banzhulin Tunnel passes through 9 faults, half of which are occupied by weak surrounding rock. During the construction process, the design and construction unit overcame geological risks such as high gas, water inrush, mud inrush, rockburst, shallow burial and fault fracture zone, and through the research and development of more than ten patented technologies, it helped the tunnel to break through smoothly and further promote the construction of the whole line.
