The opening of the West-to-Ten high-speed railway is imminent, visiting the longest high-speed railway tunnel in the Qinling Mountains

The Xi'an to Shiyan high-speed railway will open for operation on June 30th. The Qinling Mabaishan Tunnel is 22.9 kilometers in length and is the longest tunnel on the Xishigao Railway line, utilizing a double-track single-line design. The builders overcame challenges such as small cross-sections, complex and changing geology, gradually tackling this "tough nut" step by step.
