The Chengdu-Guiyang high-speed railway is expected to open by December 2019, the Chengdu railway bureau announced on Monday.

Starting from Chengdu South Station, the railway route covers Sichuan, Yunnan and Guizhou province. With a total investment of 78 billion yuan ($12.67 billion), the railway stretches 632.6 km and runs 250 km per hour.

The Chengdu-Guiyang high-speed railway began construction on December 25 last year. After the high-speed railway goes into use, it will take only 2 hours to go from Guiyang to Chengdu, benefiting 36 million people along the railway.
