Suin Line (1937–1995)

The Suin Line (水仁線, Suijin-sen) was a narrow gauge railway line built by the Chōsen Railway (Chōtetsu) during colonial-era Korea, located in Gyeonggi Province.

History
The privately owned Chōsen Gyeongdong Railway was granted a licence to build a second railway line to haul salt from Sorae. Starting at Suwon, terminus of the railway's Suryeo Line, a 52.0 km line was built to Incheon Port via Sorae, and was opened for operation on 5 August 1937. On 26 October 1942, the Chōsen Gyeongdong Railway was acquired by the Chōsen Railway, which continued operating the line until the end of the Pacific War.

Following the partition of Korea and the establishment of the Republic of Korea, on 17 May 1946 Chōtetsu, along with all other railways in the country, was nationalised, and the new Korean National Railroad took over operation of the Suin Line. Over the following years, the KNR continued to operate the line, keeping the Suin Line name but making numerous changes; recently, the line has been undergoing conversion to.

Services
In the November 1942 timetable, the last issued prior to the start of the Pacific War, Chōtetsu operated four daily, third-class-only local passenger trains:
