History
The first section of the line, named the Hachiko North Line, opened from Kuragano to Kodama on 1 July 1931, followed by the section from Hachioji to Higashi-Hanno, named the Hachiko South Line, on 10 December 1931. The Hachiko North Line was extended southward from Kodama to Yorii on 25 January 1933, and the Hachiko South Line was extended northward from Higashi-Hanno to Ogose on 15 April 1933. The Hachiko South Line was further extended northward from Ogose to Ogawamachi on 24 March 1934, and the last section between Ogawamachi and Yorii opened on 6 October 1934, connecting the north and south sections, and completing the entire line, which became known simply as the Hachiko Line. All passenger operations were switch from steam haulage to electric trains from 20 November 1958. CTC signalling was commissioned over the entire line from 27 February 1985. On 1 April 1987, with the privatization and splitting of Japanese National Railways, the Hachiko Line was transferred to the ownership of JR East. From 16 March 1996, the Hachioji to section was electrified at 1,500 V DC, and services on the non-electrified section north of Komagawa to and from were operated separately as one-man driver only operation services using KiHa 110 series DMUs.
