The Sanin Main Line (山陰本線 San'in-honsen?) is a railway line in western Japan, which connects Kyoto and Shimonoseki, Yamaguchi, operated by West Japan Railway Company (JR West). It is the major railway line of the San'in region, approximately paralleling the Japan Sea, crossing Kyoto, Hyōgo, Tottori, Shimane, and Yamaguchi prefectures. The main portion from Kyoto to Hatabu is the longest single continuous railway line in Japan at 673.8 km, although no regularly scheduled train operates over the entire line.
Three different private companies built sections of the line, which were then nationalised and connected by the Japanese Government Railway (JGR).
The Kyoto Railway Co. opened the section to Sonobe between 1897 and 1899. The Bantsuru Railway Co. opened the Ayabe - Fukuchiyama section (as part of the current Maizuru Line) in 1904. Both companies were nationalised in 1907.
The first section opened by the JGR was between Yonago and Mikuriya in 1902, and the line was then progressively extended eastward, reaching Tottori in 1907 and Iwami in 1908, the same year the current Bantan Line opened to Wadayama and Yoka. Construction of that line continued westward, and the two lines were connected in 1912.
In the meantime the Sonobe - Ayabe section was opened in 1910, and the Fukuchiyama - Wadayama section the following year. In addition, construction from Yonago progressively westward opened to Matsue in 1908 and Izumoshi in 1910, resulting in the a 385km continuous line upon the 1912 connection mentioned above.
At the western end, the Choshu Railway Co. opened the Hatabu - Kogushi section in 1914.
From Izumoshi, construction continued progressively westward, opening to Masuda in 1923, and to Todakobama in 1925, the year that the Choshu Railway Co. was nationalised and the Kogushi - Takibe section opened, with construction then continuing from both directions until the two sections were connected in 1933, completing the current line.
The Yonago - Hoki-Daisen section was duplicated between 1962 and 1966, with the Ayabe - Fukuchiyama section duplicated in 1968/9, and the Tamatsukuri-Onsen - Kimachi section in 1970.
The Matsue - Higashi-Matsue section was duplicated in 1979, and the Yonago - Yasugi section in 1980.
The original Saga-Arashiyama - Umahori section was built on the banks of the Hozugawa in a narrow gorge. A new dual track alignment was opened in 1989, and the original alignment is now operated as the Sagano Scenic Railway. Further duplication occurred in stages, so that the entire Kyoto - Sonobe section was duplicated by 2010.
The Hoki-Daisen - Izumoshi section was electrified in 1982 in conjunction with the electrification of the Hakubi Line.
The Fukuchiyama - Kinosaki section was electirified in 1986 in conjunction with the electrification of the Fukuchiyama Line.
The Sonobe - Fukuchiyama section was electrified in 1985/6, and the Kyoto - Sonobe section in 1990.
CTC signalling was commissioned between Kyoto and Igumi (204km) in 1970/71.
Former connecting lines
- Fukuchiyama station - The Hokutan Railway Co. operated a 12km line to Koumori between 1923 and 1971.
- Ebara station - The Izushi Railway Co. operated an 11km line to its namesake town between 1929 and 1970.
- Iwami station - The Iwai Prefectural Government opened a 3km 762mm gauge line to Iwai Onsen in 1925. In June 1934 149 of the 216 buildings at Iwai Onsen burnt down, and then in September that year Typhoon Muroto caused such extensive damage to the line that it was out of service until February 1936. In 1944 the line was closed and materials recycled for the Japanese war effort.
- Kurayoshi station - In 1912 a 4km line to Kamii opened, and was extended 11km to Sekigane in 1941 and a further 5 km (as a passenger only section) to Yamamori in 1958. Freight services ceaed in 1974 and the line closed in 1985.
- Yonago station - The Hakuhi Electric Railway Co. operated a 12km line, electrified at 600 VDC, to Hosshoji between 1924 and 1967. A 6km electrified branch from Aga to Mori operated between 1930 and 1944.
- Arashima - The Hirose Railway Co. opened an 8km line, electrified at 600 VDC to Izumo Hirose in 1928. In 1954 the company merged with the Ichibata Electric Railway Co., and the line closed in 1960.
- Izumoshi station -
On the northern side of the station, the 8km Taisha Line opened in 1912, on the opposite bank of the Ogamogawa to the Izumo-Taisha station on the Ichibata Electric Railway line. Freight services ceased in 1974, and the line closed in 1990.
On the southern side, the Taisha Miyajima Railway Co. proposed to build a 92km line to Hiroshima. The 19km line to Izumo Susa opened in 1932, and the planned extension was formally abandoned in 1938. The line closed in 1965 as a result of flood damage.
- Nishi-Hamada - A 2km freight-only line to Hamada Minato to service the port operated between 1955 and 1982.
- Hatabu station - The Choshu Railway Co. opened a 27km line from Higashi-Mozeki to Kogushi in 1914. A proposed extension to Nagato was not built due to funding constraints, but the line was electrified at 600 VDC in 1926. The company merged with the Sanyo Electric Railway in 1928, and the line closed in 1971.
