Lhasa-Nyingchi Railway passes through the Yarlung Zangbo River Suture Zone between the Gangdise and the Himalaya land masses on the Qinghai-Tibet Plateau. More than 90% of the railway built in areas over 3,000m above sea level. Therefore, high altitude and hypoxia, severe natural environment as well as complex geological conditions have posed great challenges to the project.
