The 650-kilometer Chengdu-Guiyang railway, an important part of the country's high-speed rail network, is put into operation on Dec. 16.

Running through mountainous terrain, the railway connects a number of tourist attractions including Huangguoshu Waterfall, Mount Emei and Leshan Giant Buddha.

China Railway Chengdu Group Co., Ltd. said trains can run at a speed up to 250 kph on the 632-km railway, linking the capital of Sichuan Province and the capital of Guizhou Province.

The construction of Chengdu-Guiyang Railway started in 2013. A 370-km long section of the railway has 85 percent of its route running on bridges and in tunnels.
