GUIYANG, Aug. 8 (Xinhua) -- A Fuxing bullet train departed on Tuesday morning from Guiyang, capital city of southwest China's Guizhou Province, marking the full operation of the Guiyang-Libo section of the Guiyang-Nanning High-speed Railway.

The Guiyang-Nanning High-speed Railway is the first high-speed rail with a designed speed of 350 km/h for both Guizhou Province and south China's Guangxi Zhuang Autonomous Region, of which Nanning is the capital city.

Due to complicated landforms along the rail section, including high mountains and steep valleys, the Guiyang-Libo section consists of 86 bridges and 62 tunnels. The mileage of bridges and tunnels accounts for 90 percent of the total mileage of the section.
