Yeongdong Line

The Yeongdong Line is a line of Korail. It connects Yeongju in North Gyeongsang Province with Gangneung in Gangwon Province. From Yeongju, it crosses the Taebaek Mountains and reaches the Sea of Japan (East Sea) at Donghae, thence proceeding north to Gangneung.

At Yeongju, the line connects with the Gyeongbuk and Jungang Lines. Some trains travel directly from one to the other, so that it is possible to travel directly from Seoul or Busan to Gangneung by rail.

The first 41.4 km (25.7 mi) section of the line (Mukho Port–Dogye) was opened by the privately owned Samcheok Railway on 31 July 1940. The line was named Cheoram Line, which ran from Mukho, a port on Korea's east coast that became part of Donghae in 1980, to Cheoram in the Taebaek Mountains, to develop three coal fields. Between Simpo-ri and Tong-ri stations, the great height difference was scaled by a steep double-track railway. Freight railcars going up and down were connected to the same cable, passengers had to walk up the mountain. A 12.9 km (8.0 mi) branch from Bukpyeong station (today Donghae station) to Samcheok, the Samcheok Line, was opened on 11 February 11.

Another section of the future Yeongdong Line was first projected as a branch line from Yeongju to Chunyang for the exploitation of the forest areas and mines in the area, the Yeongchun Line. Permission to build the line was given to the privately owned Chosen Railway on 16 October 1944, and work began that year with local forced labourers. Although the first section from Yeongju to Naeseong (today Bonghwa) was almost complete by August 1945, that month World War II ended, a Korean provisional government formed, and a flood damaged the tracks, leading to the abandonment of the line. After the nationalisation of the line work resumed in 1949, when the Economic Cooperation Administration, the United States government agency administering the Marshall Plan, also launched a plan to revive South Korea's economy, which included the construction of new railway lines. One new line under the plan was the 86.4 km (53.7 mi) long Yeongam Line from Yeongju to Cheoram, which included and extended the Yeongchun Line alignment planned by the Chosen Railway to link up the Cheoram Line with the rest of the network. The reconstructed 14.1 km (8.8 mi) from Yeongju to Naeseong opened in March 1950. Construction was interrupted again because of the Korean War in 1950. After the end of the war work was resumed in 1953, and the last section finally opened in 1955. The scenic Yeongam Line included 55 bridges and 33 tunnels:

Following the 1961 coup, the Supreme Council for National Reconstruction started South Korea's first five-year plan, which included a construction program to complete the railway network, to foster economic growth. The Gangwon Bukbu Line, a railway along the eastern coast from Mukho to Gyeongpo-dong in Gangneung, the endpoint of a narrow-gauge railway to Sokcho, was opened until 1962 as follows:

This line was also called the Donghae Bukbu Line with view to a planned connection with the existing line by the same name further north. On May 17, 1963, the Yeongam, Cheoram and Gangwon Bukbu Lines were integrated into a single line from Yeongju to Gangneung under the present name as the Yeongdong Line. Meanwhile, from August 1961, the 8.5 km (5.3 mi) Hwangji switchback section was built to bypass the cable-hauled section between Simpo-ri and Tong-ri stations, which opened on May 30, 1963.

A number of branches were built from the line, among them the 9.0 km (5.6 mi) long Hwangji Branchline from Baeksan to Hwangji (today Taebaek), which opened on December 20, 1962, and was integrated into the Taebaek Line in 1973.

After the closure of the Gangneung–Gyeongpo-dong section on March 1, 1979, the total length of the line reduced from 200 km (124.3 mi) to 193.6 km (120.3 mi).
