In southwest China’s Yunnan province, construction of a high-speed railway connecting the capital city of Kunming with Shanghai has just been completed. The high-speed railway is the first for Yunnan.

The route is about 380 kilometers and connects the remote southwest with the prosperous eastern China. Engineers say there were great challenges during construction, but they were overcome. Yunnan is situated in a mountainous area, but engineers managed to build nearly 130 bridges and 40 tunnels.

Test runs of the railway will be conducted in June, with plans open to the public by the end of the year.
