CHENGDU, Dec. 26 (Xinhua) -- A railway linking Chengdu and Kunming, two major cities in southwest China, is now fully operational with the opening of its last section on Monday.

With a designed speed of 160 km per hour, the new 915-km line, which runs almost parallel to an existing railway link between Chengdu and Kunming, cuts the travel time from 19 hours to 7.5 hours.

The new line runs through a number of cities and prefectures, such as Chengdu, Meishan, Leshan, Liangshan Yi Autonomous Prefecture and Panzhihua in Sichuan Province, and Chuxiong Yi Autonomous Prefecture and Kunming in Yunnan Province.
