Kanggye Line
The Kanggye Line is an electrified narrow-gauge line of the Korean State Railway in North Korea running from Kanggye on the Manp'o Line to Rangrim, primarily hauling forest products. An interesting feature of the line is a significant switchback west of Rangrim. History
The Kanggye Line was built by the Korean State Railway in the late 1940s to aid in the construction of a hydroelectric dam on the Changjin River in the Rangrim mountains; construction of the dam had been started by the Japanese in 1937. Following an order issued in September 1999 by Kim Jong-il, electrification of the line at 1500 V DC was completed on 5 October 2000. Route
