The Kangan Line, also spelled Kang'an Line, is a non-electrified standard-gauge freight-only secondary line of the Korean State Railway located entirely within Sinà Âiju-si, North P'yà Ângan Province, North Korea, running from Sinà Âiju on the P'yà Ângà Âi Line to Kang'an.
For the original line's history and other information prior to 1945, see Gyeongui Line (1904âÂÂ1945).
In 1911, the Yalu River Railway Bridge was completed across the Yalu River between Sinà Âiju and Andong (now Dandong), China, connecting the Kyà Ângà Âi Line to the Anfeng Line of the South Manchuria Railway. Work to convert the Anfeng Line from narrow gauge to standard gauge was completed at the same time, thus connecting the capitals of Korea and China with a continuous railway line via and Manchuria.
As a result, Sentetsu opened a new station in Sinà Âiju (on the site of today's Sinà Âiju Ch'à Ângnyà Ân Station), with the original station, located northwest of the new station, being renamed Lower Sinà Âiju Station.
On 1 November 1935, Sentetsu opened Pinjà Âng Station between Sinà Âiju and Lower Sinà Âiju stations, but closed it again on 15 November 1941.
On 1 June 1936, Lower Sinà Âiju station was renamed Sinà Âiju Kang'an Station, and the line from Sinà Âiju Station to Sinà Âiju Kang'an Station was detached from the Kyà Ângà Âi Line to become the Kang'an Line.
Passenger service on the Kang'an Line was discontinued on 31 March 1943, with general (public) freight traffic being relocated from Sinà Âiju Kang'an to Sinà Âiju station on 20 December of that year.
The Kang'an Line is used to serve the various industries in Sinà Âiju, such as the Sinà Âiju Streptomycin Factory and the Sinà Âiju Chemical Fibre Complex (called the "Chà Âsen Paper Mills, Ltd." prior to 1945). There is also a large workshop for maintenance of passenger cars at Kang'an Station.
