Sekihoku Main Line (石北本線 Sekihoku-honsen?) is a Japanese railway line in Hokkaido, operated by Hokkaido Railway Company (JR Hokkaido) between Shin-Asahikawa in Asahikawa and Abashiri Station in Abashiri. The name comes from Ishikari Province (狩国?) and Kitami Province (見国?), names of ancient provinces along the line.[1]

Basic data[edit]

Services[edit]

The Okhotsk limited express train, named after the Sea of Okhotsk, runs from Sapporo to Abashiri four times a day in summer, six times a day in winter.[2] The limited rapid train Kitami operates between Asahikawa and Kitami, with one return service daily.

As for the local service, the line is roughly divided into three segments. In the segment between Asahikawa and Kamikawa, the line functions as a commuter rail of Asahikawa City. There is one local train service per one to two hours. The segment between Kamikawa and Engaru is a sparsely populated area. Between Kakikawa and Shirataki, a local train runs one lap per day. For the segment between Engaru and Abashiri, there is one local train service per one to two hours.

History[edit]

The principle route between Sapporo and Okhotsk Subprefecture has changed several times. Originally, the route was the Hakodate Main Line to Asahikawa, then the southbound Nemuro Main Line and then the northbound line from Ikeda, via the Abashiri Main Line (網走本線 Abashiri-honsen?) to Kitami. The route shortened by 53.5km when the section between Takikawa and Furano on the Nemuro Main Line opened in 1913.

Another route, northbound from Asahikawa to Nayoro, then southeast to Kitami was completed as the Nayoro Main Line (名寄本線 Nayoro-honsen?) and Yūbetsu Line (湧別線 Yūbetsu-sen?) in 1921.

A third route was a shortcut between Asahikawa and Engaru, straight through the Kitami Pass. The Sekihoku Line (石北線 Sekihoku-sen?), completed in 1932, finally completed the main route still used today.

The current Sekihoku Main Line consists of the remnants of these three lines. The section between Shin-Asahikawa and Engaru is from the Sekihoku Line, the section between Engaru and Kitami from the Yūbetsu Line, and the section between Kitami and Abashiri from the Abashiri Main Line.

The first of the abovementioned sections to open was from Abashiri to Kitami in 1912. The Kitami - Engaru line was opened between 1912-15 as a 762mm (2'6") gauge line, but was converted to 1067mm (3'6") gauge in 1916.

The Asahikawa - Kamikawa section opened in 1922-23, and the Engaru - Shiritaki section in 1927-29. The final section, including the Ishikita tunnel, opened in 1932.
