The Nayoro Main Line ( Japanese 名 寄 本 線 , Nayoro-honsen ) was a railway line on the Japanese island of Hokkaidō . It opened up the sparsely populated northeast of the island, was opened between 1915 and 1921 and was in operation until 1989.

description

The Nayoro main line consisted of a 138.1 km long main line and a 4.9 km long branch line. Both were Cape gauge , single-track and not electrified. A total of 40 train stations and stops were opened up.

In Nayoro, the main line branched off from the Sōya main line and initially led eastwards through the Nayoro Valley. She crossed the Kitami Mountains at the 300 meter high Tenpoku Pass. North-east through the Okoppe Valley, she reached Okoppe on the Sea of ​​Okhotsk . From there it followed the coast in a southeasterly direction. After Mombetsu , the route led a few kilometers inland to pass the Komuke-ko and Shibunotsunai-ko lagoons on their south side. Eventually it ran south through the Yūbetsu Valley to Engaru , where it met the main Sekihoku line . The branch line ran from Naka-Yūbetsu to the center of Yūbetsu .

history

In the Hokkaidō Railway Construction Act passed by the Japanese Reichstag in 1896 , the Nayoro main line was sketched for the first time, but the implementation of this project by the Railway Authority (later the Ministry of Railways ) took two decades to come. On November 1, 1915, the Yūbetsu Kleinbahnlinie ( 湧 別 軽 便 線 , Yūbetsu-keibensen ) was extended from Yasukuni via Engaru to Kaisei, with the Engaru – Kaisei section forming the first section of the later Nayoro main line. The track was initially 762 mm, but already on November 7, 1916, took place Umspurung in the usual Cape gauge (1,067 mm). With the commissioning of the section from Kaisei via Naka-Yūbetsu to Yūbetsu on November 21, 1916, the so-called Yūbetsu Line ( 湧 別 線 , Yūbetsu-sen ) was completed.

On October 20, 1919, the Ministry of Railways opened the first section of the Nayoro Line ( 名 寄 線 , Nayoro-sen ) from Nayoro to Shimokawa (16.5 km). The section from Shimokawa to Kami-Okoppe (22.4 km) followed on October 25, 1920, that from Naka-Yūbetsu to Okoppe (54.1 km) on March 25, 1921. The last section was on October 5, 1921 , 9 km long section between Kami-Okoppe and Okoppe put into operation, completing the project. On November 5, 1923, the Nayoro Line was renamed the Nayoro Main Line. The Nayoro Line and the north of Engaru located part of the Yūbetsu Line were merged on October 1, 1932 to form the new Nayoro Main Line. From June 1, 1935, combustion railcars were used for the first time between Naka-Yūbetsu and Yūbetsu .

The Japanese State Railways , which was responsible from 1949, set up numerous stops on demand in order to enlarge the catchment area. Express trains also ran from 1962 to 1986 . These measures could not stop the steady loss of importance of the Nayoro main line. On November 1, 1978, the state railway stopped freight traffic on the Yūbetsu branch line. Two years after the Ministry of Transport had classified the Nayoro main line as unprofitable, it became the property of the new company JR Hokkaido on April 1, 1987 as part of the privatization of the state railway . Freight traffic was completely stopped on the same day. JR Hokkaido closed the Nayoro main line on May 1, 1989 also for passenger traffic. Several bus routes took their place.
