How many Chinese famous Railways do you know?
Over 70 years of development, China's railways are intertwined and integrated with the country, the nation, and the people. Chinese railway workers keep forging ahead in the process of tempering, and keep moving forward in the process of making progress. Chinese railway workers have won one success after another with their own efforts, helping the development of the society, and showing the connotation of "China's name card".
(1) Nanning-Kunming Railway

Nanning-Kunming Railway--the most beautiful and steep trunk line. The Nanning-Kunming Railway starts from Nanning in the East, Kunming in the West, and Hongguo in the North, with a total length of 899.7 km. It is a National first-class electrified railway trunk line connecting Guangxi, Guizhou, and Yunnan. Along the way, there are high gorges and deep valleys, and beautiful landscapes. Many world firsts and Asian firsts were created on the Nankun Railway.

The Xinguanjiao Tunnel is the longest high-altitude tunnel in the world and the longest tunnel in China, with a total length of 32.645 kilometers. Can you imagine how difficult to construct so long a tunnel? The project was fully started on November 6, 2007. After nearly seven years, the project was completed on April 15, 2014.
