The Tobu Tojo Line (東武東上線 Tōbu Tōjō-sen) is a 75.0 km suburban railway line in Japan which runs from Ikebukuro Station in Toshima, Tokyo to Yorii Station in Yorii, Saitama, operated by the private railway operator Tobu Railway. Its official name is the Tobu Tojo Main Line (東武東上本線 Tōbu Tōjō Honsen), but it is referred to as Tobu Tojo Line (東武東上線 Tōbu Tōjō Sen) on Tobu signage and publicity information.

The Tojo Line and Tobu Ogose Line branch are isolated from other Tobu lines, such as the Isesaki Line and Nikko Line. There was a plan to connect between Nishiarai on the Isesaki Line and Kami-Itabashi on the Tojo 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 old province now Gunma Prefecture).

Rolling stock depots

The main maintenance depot for the line is Shinrinkoen Depot, to the north of Shinrinkoen Station. This opened in March 1971, and as of December 2013 has an allocation of 678 vehicles (the entire fleet used on the Tojo Line and Ogose Line).[3] A smaller maintenance depot is also located at Kawagoe, on the south side of Kawagoeshi Station. This was the main maintenance depot from the time the line first opened in 1914 until the larger facility at Shinrinkoen was built in 1971. Kawagoe Depot still carries out lighter maintenance and inspection duties.[3] A stabling yard is located to the south of Shimo-Itabashi Station. Built in 1935, this is capable of stabling eight 10-car trains, and is used for stabling trains close to Ikebukuro outside the peak hours.[3]

History

The "-1.9" kilometre post just outside the station

On 1 May 1914, the Tojo Railway (東上鉄道 Tōjō Tetsudō) opened the 33.5 km section between Ikebukuro and Tanomosawa (田面沢駅) (located between the present stations of Kawagoeshi and Kasumigaseki).[3] The Tokyo terminus of the line was originally planned to be at Shimo-Itabashi, and this is where, even today, the "0 km" post for the line is located (with Ikebukuro Station marked by km post "-1.9").[3] The section from Shimo-Itabashi to Ikebukuro was initially treated as a light railway extension of the main line.[3] 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.[4]

In 1920, the Tojo Railway was absorbed into the Tobu 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 Tobu Tojo Line.[3] 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 the Chichibu Railway.

The line from Ikebukuro to Yorii was electrified in October 1929.[3] 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.

The Ikebukuro to Shiki section was double-tracked between 1935 and 1937, extended to Kawagoe in 1954, to Higashi-Matsuyaa between 1965 and 1968, to Shinrinkoen in 1977, and to Musashi-Ranzan between 2002 and 2005.

In 1949, Flying Tojo limited express services commenced, running between Ikebukuro and Nagatoro on the Chichibu Railway, initially using 5310 series EMUs with transverse seating, and taking approximately two hours.[3] The name was inspired by the Flying Scotsman express train service running in Britain.[3] This service continued until December 1967.[3] Steam for freight haulage on the line was finally withdrawn in 1959.[5]

Freight services ceased in 1986. In 1987, the Yurakucho 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).

June 2008 timetable revision

From the start of the revised timetable on 14 June 2008, new limited-stop evening TJ Liner services commenced using new 50090 series rolling stock. Six down services operate on weekdays, with four at weekends. Trains from Ikebukuro stop at Fujimino, Kawagoe, Kawagoeshi, Sakado, Higashi-Matsuyama, and Shinrinkōen, with some services continuing to Ogawamachi stopping at Tsukinowa and Musashiranzan stations.[6] Limited Express services were discontinued and replaced by new Rapid Express (快速急行) services. Daytime express services were increased from four to five per hour, and semiexpress services were reduced from four to three per hour. All trains operating out of Ikebukuro are standardized as 10-car trains.[7] From this date, the maximum line speed was increased from 100 km/h (60 mph) to 105 km/h (65 mph).[5]

March 2011 timetable revision

From the start of the revised timetable on 5 March 2011, TJ Liner services were increased from six to nine on weekday evenings. The irregularly spaced daytime express services were adjusted to run at 12-minute intervals, and semi-express services were adjusted to run at 20-minute intervals.[8]

From 17 March 2012, station numbering was introduced on all Tobu lines. Tobu Tojo Line and Ogose Line stations were numbered prefixed with the letters "TJ".[9]

From 10 September 2012, 10-car 5050-4000 series sets entered revenue service on the Tobu Tojo Line, with inter-running through to the Tokyo Metro Fukutoshin Line.[10]

March 2013 timetable revision

From the start of the revised timetable on 16 March 2013, through running via the Tokyo Metro Fukutoshin Line was extended beyond Shibuya over the Tokyu Toyoko Line and Minatomirai Line to Motomachi-Chukagai in Yokohama.[11] New "Rapid" services were introduced, with the previous daytime off-peak pattern of five Express services hourly changed to four Express and two Rapid services per hour in each direction.

March 2016 timetable revision

Following the revised timetable introduced on 26 March 2016, through services to and from Motomachi-Chukagai in Yokohama, running via the Tokyo Metro Fukutoshin Line were extended to Shinrinkoen, and upgraded to "Express" status, branded as "F Liner". Weekday morning TJ Liner services were introduced in the up direction to Ikebukuro.[12] Morning Commuter Express (通勤急行 Tsūkin-kyūkō) services were discontinued from this date.
