Chikuhō Main Line
# Chikuhō Main Line

The Chikuhō Main Line (筑豊本線, Chikuhō-honsen) is a railway line in Fukuoka Prefecture, Japan, operated by Kyushu Railway Company (JR Kyushu). It connects Wakamatsu Station in Kitakyushu with Haruda Station in Chikushino. Between Orio Station and Haruda Station, as well as from Keisen Station via the Sasaguri Line to Yoshizuka Station, the line functions as an alternate route to the Kagoshima Main Line.

## Line data

As of 2021, the Chikuho Main Line is the third shortest of all Japan Railways Group lines named Main (or trunk) Line (not counting the JR Shikoku main lines, which were stripped of their designation after JR Shikoku started operating). For comparison, the shortest is Hidaka Main Line (30.5 km), after the closure of 116.0 km due to storm damage in 2015.

The line is divided into three sections. Each section has an alias.

## History

The 39 km Wakamatsu to Iizuka section was built by the Chikuho Kogyo Railway, opening between 1891 and 1893, with the 12 km extension to Chikuzen Uchino opening in 1895. The company was nationalised in 1907, with the 15 km Chikuzen Uchino to Harada section opening in 1929.

The 25 km section from Wakamatsu to Nogata was double-tracked between 1893 and 1896, with the 4 km Nogata to Kotake section double-tracked between 1904 and 1906. The 8 km Kotake to Iizuka section was double-tracked between 1942 and 1944.

The 35 km Orio to Keisen section was electrified in 2001.
