# Sasebo Line

The Sasebo Line (佐世保線, Sasebo-sen) is a railway line in Kyushu, Japan, operated by the Kyushu Railway Company (JR Kyushu). It connects Kōhoku Station in Kōhoku, Saga Prefecture to Sasebo Station in Sasebo, Nagasaki Prefecture. It is part of the route connecting Sasebo with Saga and Fukuoka. Most of the line runs parallel to National Routes 34 and 35. From 1898 to 1934 the Kōhoku - Haiki section was part of the original Nagasaki Main Line.

## History

The Kyushu Railway Co. opened the Yamaguchi (present-day Kōhoku) - Takeo (present-day Takeo-Onsen) section in 1895 as part of the original Nagasaki Main Line. It was extended to Haiki in 1897, and to Sasebo the following year. The company was nationalised in 1907.
In 1934 the Hizen-Yamaguchi (present-day Kōhoku) - Isahaya line opened as the new Nagasaki Main line, with the line being renamed the Sasebo Line. The history of the line beyond Sasebo is covered under the Matsuura Line.
The entire line was electrified in 1976, and freight service ceased between Haiki - Sasebo in 1985, Arita - Haiki in 1987 and on the balance of the line in 1996.
The section between Takahashi station and Omachi station will be double-tracked as the current compromise until the construction of the Kyushu Shinkansen Nagasaki route between Takeo-Onsen and Shin-Tosu can be decided.
