Gui-Nan High-Speed Railway Project

The Gui-Nan High-Speed Railway is a high-speed railroad in China connecting the city of Guiyang in Guizhou Province with Nanning, the capital of the Guangxi Zhuang Autonomous Region. It constitutes a vital section of the "Baotou (Yinchuan)-Haikou Channel," one of the main corridors outlined in the "Mid-to-Long Term Railway Network Plan" (revised edition 2016), under the "Eight Verticals and Eight Horizontals" high-speed railway network. Spanning 481 kilometers in length, it is the first high-speed railway in southwestern China designed to operate at a speed of 350 km/h. The project used Yufeng P.O42.5 (high-speed railway dedicated) cement and P.O52.5 cement, by an estimated supply volume of around 500,000 tons.
