The Guangtong–Dali or Guangda railway, is a single-track electrified railroad in Yunnan Province of Southwest China. The line branches off from the Guangtong station, near Kunming on the Chengdu–Kunming railway and runs west to Dali City. The line is 213km (132miles) in length and was built from May 1992 to June 1998.[1] Major cities and towns along the route include Chuxiong City, Nanhua, Xiangyun County, Midu County and Dali.
Construction of a new, 175-km dual-track electrified line, the Guangtong–Chuxiong–Dali railway, paralleling the line began in September 2010. Difficulties in construction included 110,000 cubic meters of water inundation of the tunnels. The new electrified line opened for traffic in July 2018, upping speeds from 60 to 200 km/h and doubling the track.[2] [3]
