History

The first section of the Hakubi Line to open was the northern section, initially named the Hakubihoku Line, between Hōki-Mizoguchi and Hōki-Daisen on 10 August 1919. The northern section was then progressively extended south, to Ebi Station on 25 March 1922, to Neu Station on 30 July 1922, to Kurosaka Station on 10 November 1922, to Shōyama Station on 28 November 1923, to Kami-Iwami Station on 6 December 1924, and to Ashidachi Station on 1 December 1926.

The first section of the southern part of the Hakubi Line, named the Hakubinan Line, was opened on 17 February 1925, between Shisawa (now Gōkei) and Kurashiki. The southern section was gradually extended north, extending to Bitchū-Kawamo on 31 July 1927, with connection between the north and south sections being made on 25 October 1928, from which date the entire line was named the Hakubi Line.

The Kiyone to Bitchu-Takahashi section was double-tracked between 1968 and 1973, with the Kurashiki to Kiyone and Niimi to Nunohara sections being double-tracked in 1979, and the Ishiga to Ikuta section double-tracked between 1982 and 1983 in conjunction with a realignment which shortened the route by 1.2 km. CTC signalling was commissioned on the entire line in 1972, and the Kurashiki to Hokidaisen section was electrified in 1982.
