Tobu Railway |東武鉄道|Tōbu Tetsudō is a 75.0 km suburban train line that runs fromIkebukuro Station inToshima, Tokyo ,Japan toYorii Station inYorii, Saitama . Its official name is the Nihongo|Tōbu Tōjō Main Line|東武東上本線|Tōbu Tōjō Honsen, but it is referred to as Nihongo|Tōbu Tōjō Line|東武東上線|Tōbu Tōjō Sen on Tōbu signage and publicity information.The Tōjō Line and
Tōbu Ogose Line branch are isolated from other Tōbu lines, such as the Isesaki Line and Nikkō Line. There was a plan to connect between Nishiarai on the Isesaki Line and Kami-Itabashi on the Tōjō Line, but this was never built.The name of the line comes from the original plan to construct a line linking Tokyo (東京) with Jōshū (上州) (an ancient province now
Gunma Prefecture ).History
On
1 May 1914 , the Nihongo|Tōjō Railway|東上鉄道|Tōjō Tetsudō began operating, covering the 33.5 km stretch between Ikebukuro and Tanomosawa (located between the present stations of Kawagoeshi and Kasumigaseki). Two years later, the line was extended 9.2 km from Kawagoemachi (now Kawagoeshi) to Sakadomachi (now Sakado), and at the same time, the section between Kawagoemachi and Tanomosawa was abandoned.cite journal | last = Yamamoto | first = Tomoyuki | authorlink = | coauthors = | title = 東武東上線の神話時代(1)| journal = Japan Railfan Magazine| volume = 48| issue = 570| pages = 126-131| publisher = | location = | date = October 2008]In 1920, the Tōjō Railway was absorbed into the Tōbu Railway, and in 1923, the line was extended 13.4 km from Sakadomachi to Ogawamachi. In 1925, the line was further extended 10.8 km from Ogawamachi to Yorii, completing the present-day Tōbu Tōjō Line. While the original plan had been to extend the line as far as
Gunma Prefecture , the connection at Yorii did at least allow for through operations via theChichibu Railway . The line from Ikebukuro to Yorii was electrified in 1929. The 10.9 km Ogose Line from Sakadomachi to Ogose was not opened until much later, in 1943. With the steadily growing population along the line, trains were gradually increased in length to the maximum 10 cars seen today, and the original single track was doubled and even quadrupled in some places (between Wakōshi and Shiki). The line from Ikebukuro to Yorii covers a total distance of 75 km.Steam for freight haulage was finally withdrawn in 1959.
In 1987, the Yūrakuchō Line reached Wakōshi, allowing through-running from Kawagoeshi on the Tōbu Tōjō Line to the then terminus of Shintomichō (later extended further east to the present terminus of Shinkiba).
