Legend :
The Kawagoe Line (Japanese: 川越線, romanized: Kawagoe-sen) is a railway line in Japan operated by the East Japan Railway Company (JR East), which connects the cities of Saitama, Kawagoe, and Hidaka in Saitama Prefecture. The main transfer stations on the line are Ōmiya, Kawagoe, and Komagawa.

## Services

The eastern section between Kawagoe and Ōmiya operates as an extension of the Saikyō Line from central Tokyo, with most trains traveling through to/from Ōsaki and on to/from Shin-Kiba via the Rinkai Line. On the western section between Kawagoe and Komagawa, about half of all trains travel through to/from Hachiōji via the Hachikō Line.
Except for a few rush-hour trains that start and terminate at Minami-Furuya, all eastbound trains from Komagawa and westbound trains from Ōmiya terminate at Kawagoe. Passengers wishing to travel beyond Kawagoe must change trains there.

## Station list

* All stations are located in Saitama Prefecture.
* Passengers bound for Ōmiya or Komagawa must change trains at Kawagoe. However, during early mornings and evenings, some trains leaving Kawagoe depot provide service from Minami-Furuya to Komagawa.
* All rapid or commuter rapid trains to/from the Saikyo Line stop at every station on the Kawagoe Line.
* Trains can pass each other at stations marked "∥", "∨", and "◇"; they cannot pass at stations marked "｜".

## History
### Line opening

A line linking Ōmiya with Kawagoe and continuing to the Hachikō Line at Komagawa was first proposed in March 1920. Construction work started in September 1935, with the line opening on 22 July 1940.

### Switch to diesel

Services were initially steam hauled, but diesel multiple unit trains were introduced from 1 June 1950. The final steam-hauled passenger train ran on 30 September 1969.

### Electrification

The line was electrified (1,500 V DC) from 30 September 1985, and through running commenced to and from the Saikyō Line, which opened at the same time. The tracks were doubled between Ōmiya to Nisshin, and a new EMU depot was opened close to Minami-Furuya Station. A special "Kawagoe Line Diesel Sayonara" train ran on the line on 3 November 1985.

### Hachikō Line through services

Through services between Kawagoe and Hachiōji on the Hachikō Line began on 16 March 1996 following the electrification of the southern section of the Hachikō Line between Komagawa and Hachiōji.
