Route map

The Kyūdai Main Line (久大本線, Kyūdai-honsen) is a railway line in Kyushu, Japan, operated by the Kyushu Railway Company (JR Kyushu). It connects Kurume Station, Kurume in Fukuoka Prefecture and Ōita Station, Ōita in Ōita Prefecture. It is also known as the Yufu Kōgen Line.

The line crosses the whole of Kyushu, approximately paralleling the Chikugo River and its tributary the Kusu River near Kurume, and along the Ōita River close to Ōita. It also traverses popular tourist resorts such as Hita (known as Little Kyoto) and spa resorts around Yufu.

Stations

History

In 1915, the Daito Railway Co. opened the 22 km Oita - Onoya section. The company was nationalised in 1922, and westerly extensions were undertaken in stages from 1923 until Amagase was reached in 1933. The Kurume - Chikugoyoshi opened in 1928, and easterly extensions to Amagase opened between 1931 and 1934.^{[ citation needed]}

CTC signalling was commissioned over the entire line in 1984, and freight services ceased in 1987.

Typhoon damage

In 2012, a landslide disrupted services for 6 weeks.

On 5 July 2017, torrential rainfall washed out the bridge over the Oita River between Chikugo Oisha and Teruoka, resulting in the closure of the section. According to the Japanese language Wikipedia article, the line was fully re-opened on 14 July 2018.
