The Sasshō Line (札沼線, Sasshō-sen) is a railway line in Japan operated by Hokkaido Railway Company (JR Hokkaido), which connects Sōen in Sapporo and Hokkaidō-Iryōdaigaku in Tōbetsu, Ishikari District. Its name is made up of two characters from Sapporo (札幌) and Ishikari-Numata (石狩沼田), the latter of which was the terminus of the line until it was relocated to Shin-Totsukawa in 1972.

History
editThe first part of the line to open was the northern (and now closed) section between Ishikari-Numata (on the Rumoi Main Line) to Nakatoppu (present-day Shin-Totsukawa). This opened on 10 October 1931, and was initially named the Sasshō North Line (札沼北線, Sasshō-hoku-sen).[3] This line was extended southward from Nakatoppu to Urausu on 10 October 1934, and the Soen to Ishikari-Tobetsu section, initially named Sasshō South Line (札沼南線, Sasshō-nan-sen), opened on 20 November 1934.[3] The section between Urausu and Ishikari-Tobetsu opened on 3 October 1935, linking the north and south lines, which were unified as the "Sasshō Line".[3]
Nakatoppu Station was renamed Shin-Totsukawa in 1953.[citation needed]
The section between Shin-Totsukawa and Ishikari-Numata was closed on 1 April 1972.[3]
With the privatization of JNR on 1 April 1987, ownership of line was transferred to JR Hokkaido.[3]
Duplication
editThe section between Hachiken and Ainosato-Kyoikudai was double-tracked between 1995 and 2000.[citation needed]
Electrification
editThe line was electrified over the 28.9 km section from Sōen Station to Hokkaidō-Iryōdaigaku Station in 2012, with engineering work completed by March 2012. New 733 series EMUs were introduced from June 2012,[4] with all trains operated using EMUs from the start of the revised timetable on 27 October 2012.[5]
Part Closure in 2020
editJR Hokkaido had been planning to permanently close the section between Hokkaido-Iryodaigaku and Shin-Totsukawa on 7 May 2020, but the company moved closure forward to 17 April due to the COVID-19 outbreak.[6]
Former connecting lines
edit- Shinkotoni Station: An 11 km horse-drawn 762 mm (2 ft 6 in) gauge line operated from Sapporo north west to Kawabata, opening in 1911 and crossing the Sassho Line near Shinkotoni. Petrol locomotives were introduced in 1922. The line was replaced by buses in 1943.
- Tobetsu Station: A 31 km 762 mm gauge line was opened to Obukuro in sections between 1949 and 1952. Typhoon Marie (1954) caused significant damage to the line, and repair was considered impractical. The line was formally closed in 1958. An 11 km 762 mm gauge line operated to Ebetsu, on the Hakodate Main Line, although at each terminus, the 762 mm gauge stations were on the opposite banks of the Tobetsugawa and Ishikarigawa rivers (respectively) to the JR stations.
