Karatsu Line
# Karatsu Line

The Karatsu Line (唐津線, Karatsu-sen) is a regional railway line in Saga Prefecture, Japan, owned and operated by Kyushu Railway Company (JR Kyushu). It connects Kubota in Saga City to Nishi-Karatsu in Karatsu City, both in Saga Prefecture, Japan. The line was originally constructed to carry coal from the Karatsu coal fields to the Port of Karatsu for export and had many branch lines to coal mines which have since closed.

## Operation

All trains running on the Karatsu Line stop at all stations along the line, including through services from both sections of the Chikuhi Line. All trains that run to/from Kubota Station use the Nagasaki Main Line to terminate at Saga Station instead.

## Station list

Station numbering has not been introduced for the Karatsu Line, but both Karatsu and Nishi-Karatsu use the station numbering from the eastern section of the Chikuhi Line.

## History

The Karatsu Kogyo Railway opened a line from Myōken (妙見) (today Nishi-Karatsu to Yamamoto in 1898, on an alignment paralleling the west bank of the Matsuura River, and extended the line to Taku the following year. In 1902, the company merged with the Kyushu Railway Co., which extended the line to Kubota in 1903. The company was nationalised in 1907. From 1898 to 1912, a number of freight only branch lines were also built.

The Chikuhi Line from Higashi-Karatsu was extended to Yamamoto in 1929 on an alignment paralleling the east bank of the Matsuura River.

In 1983, the Chikuhi line was rebuilt so it branched at Karatsu, with the Karatsu - Nishi-Karatsu section being electrified at 1,500 V DC at the same time in conjunction with the electrification of the Chikuhi line, together with CTC signalling from Nishi-Karatsu to Kubota.

The last of the freight only branch lines closed in 1982. Freight services ceased in 1986.
