Chikuhi Line

The Chikuhi Line (筑肥線, Chikuhi-sen^?) is a railway line in Kyushu, Japan, connecting Meinohama Station in Fukuoka, Fukuoka (and via a subway through service, Fukuoka itself) to Karatsu Station in Karatsu, Saga, and from Yamamoto Station in Karatsu to Imari Station in Imari, Saga. Trains from Karatsu to Imari use the Karatsu Line to Yamamoto.

A fleet of six new 305 series 6-car electric multiple unit (EMU) commuter trains was introduced on the Chikuhi Line from February 2015.

The Kita-Kyushu Railway Co. opened the Fukuyoshi - Hamasaki section in 1923, extending it west to Higashi-Karatsu (situated on the east bank of the Matsuura River, opposite the Karatsu Line on the west bank) in 1924 and east to Hakata in 1924 and 1925. The line was again extended west to Yamamoto where it junctioned with the Karatsu line (establishing Higashi-Karatsu as a reversing station in the process) in 1929, and to Imari in 1935. Diesel locomotives were introduced in 1933, and the company was nationalised in 1937.

In 1983, the Hakata - Meinohama section was closed and replaced by a link to the Fukuoka City Subway Airport Line, a new line from Nijinomatsubara to Karatsu opened (including a new station called Higashi-Karatsu, situated about 1.5 km southeast of the original station of that name) and the entire section was electrified at 1,500 V DC to allow through running to Fukuoka via the subway. At the same time, the original Nijinomatsubara - Yamamoto section closed. The Meinohama - Shimoyamato section was double-tracked in 1986, with double-tracking extended to Chikuzen-Maebaru in 1999 and 2000.
