Services
Komagawa Station in Hidaka, Saitama is the boundary point between two distinct sections. The southern section from Hachiōji to Komagawa is electrified at 1,500 V DC. Some trains terminate at Komagawa, while others continue over the Kawagoe Line to Kawagoe Station. A few trains leave the Hachikō Line at Haijima Station, entering the Ōme Line and terminating at Tokyo Station.
The non-electrified northern section connects Komagawa with Kuragano. All trains continue on the Takasaki Line to Takasaki, where transfer to the Jōetsu Shinkansen is available. There are no through services connecting the southern and northern halves of the line.
The Hachikō Line takes the first kanji of its name from the first character of Hachiōji (八王子) and the second kanji from the first character of Takasaki (高崎).

The first section of the line, named the Hachiko North Line (八高北線), opened from Kuragano to Kodama on 1 July 1931, followed by the section from Hachioji to Higashi-Hanno, named the Hachiko South Line (八高南線), 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.
