The Tokyu Den-en-toshi Line (東急田園都市線 Tōkyū Den'entoshi-sen?) is a major commuter line operated by the private railway operator Tokyu Corporation and connecting south-western suburbs of Tokyo and neighbouring Kanagawa Prefecture, with its western terminus of Chūō-Rinkan, to a major railway junction of western downtown Tokyo, Shibuya. At Shibuya, nearly all the trains continue on the Tokyo Metro Hanzomon Line.

The line's color on maps and station guides is green, and stations carry the prefix "DT" followed by a number.

Operation[edit]

Nearly all trains on the Den-en-toshi Line are operated through to/from the Tokyo Metro Hanzomon Line using Tokyu, Tokyo Metro, and Tobu Railway 10-car EMUs. Around half of them continue beyond Oshiage, the terminus of the Hanzomon Line, to the Tobu Skytree Line (Kita-Koshigaya Station, Kita-Kasukabe Station and Tōbu-Dōbutsu-Kōen Station), Tobu Isesaki Line (Kuki Station), and Tōbu Nikkō Line (Minami-Kurihashi Station).

Rapid service[edit]

Tokyu operates two types of rapid services as well as Locals.

Local (普通 Futsū?) (L)
Stop at all stations. Eight service per hour per direction in day time.
Semi-Express (準急 Junkyū?) (SE)
Only up trains in weekday morning, to reduce congestion of passengers around Shibuya of rapid trains and to reduce delays with equalizing the speed of the trains.
Express (急行 Kyūkō?) (Ex)
Four trains per hour per direction in day time.

Through trains to Oimachi Line[edit]

A few trains are operated through to/from the Tōkyū Ōimachi Line to utilize forwardings to/from Saginuma depot, up to Ōimachi in the mornings, and down to Saginuma in the late evenings. These formations are 5-car sets, unlike the 10-car trains normally used on the line. A few express trains in holidays also serve from Chūō-Rinkan in the mornings, down in the evenings.

History[edit]

Prewar predecessors[edit]

On March 6, 1907, the Tamagawa Electric Railway (玉川電気鉄道 Tamagawa Denki Tetsudō?, Tamaden) opened the first section of the Tamagawa Line (玉川線 Tamagawa sen?) tramway (not to be confused with today's Tōkyū Tamagawa Line (東急多摩川線 Tōkyū Tamagawa sen?)) between Shibuya and what is now Futako-Tamagawa. Two branch lines opened from the Tamagawa Line: the Kinuta Line (砧線 Kinuta sen?) (March 1, 1924) from Futako-Tamagawa to Kinuta, and the Setagaya Line (January 18, 1925) from Sangenjaya.

Tamaden was acquired by the Tokyo Yokohama Electric Railway (東京横浜電気鉄道 Tokyo Yokohama Denki Tetsudō?) (now Tokyu) on April 1, 1938. In addition to its principal Tokyo-Yokohama line, TYER also operated the Mizonokuchi Line (溝の口線 Misonokuchi sen?) from Futako-Tamagawa (called Futako-Tamagawa-en) to Mizonokuchi from July 15, 1927. The Tamagawa Line provided a further connection past Futako-Tamagawa to Shibuya. On July 1, 1943, this section was integrated with the Ōimachi Line running from Ōimachi in southwest Tokyo to Futako-Tamagawa-en.

Tama Den-En-Toshi Plan[edit]

Before 1945, the Tama Hills southwest of Mizonokuchi were largely forested, occupied by small villages along the Ōyama Route (now Route 246) and training bases for the Imperial Japanese Army. After World War II, many farmers migrated to the area.

In 1953, at which time about 20,000 people lived in the area, Tokyu Group president Keita Gotō unveiled a "new town" planning scheme called the South-Western Area Development Plan. He envisioned new railway and freeway infrastructure (the latter being realized as the Tōmei Expressway) and large, clean houses for commuters working in Tokyo. Tokyu started accepting new residents in this Tama Den-En-Toshi ("Garden City") Plan area in 1959.

In accordance with this plan, the Ōimachi Line was renamed the Den-en-toshi Line on October 11, 1963 and officially extended to Nagatsuta on April 1, 1968.

From the 1970s onward, the population of the area increased rapidly. The towns were viewed as cultural and sophisticated, and attracted many new residents. While Tokyu Group's housing construction project is almost complete, other developers still push forward with the construction of apartmants and houses. There are now about 550,000 residences along the line, excluding the section from Shibuya to Mizonokuchi which was already urbanized prior to the plan. This makes the area the largest "new town" developed by the Japanese private sector.

Development of the line[edit]

On May 11, 1969, the former Tamagawa Line and Kinuta Line were closed for the construction of a new underground Shin-Tamagawa Line along with the Route 3 of Shuto Expressway. Tokyu provided substitute bus service during the interim. The new line began service on April 7, 1977 between Shibuya and Futako-Tamagawa: through service with the Den-en-toshi Line began on November 16, 1977.

On August 12, 1979, the section from Ōimachi to Futako-Tamagawa was separated and named the Ōimachi Line again, thus restoring its original name and route. This coincided with the inauguration of through services from the Den-en-toshi Line via the Hanzōmon Line of the then Teito Rapid Transit Authority (帝都高速度交通営団 Teito Kōsokudo Kōtsū Eidan?, Eidan or TRTA) and the Shin-Tamagawa Line.

The line was completed in its present form on April 9, 1984, when sections between Tsukimino and Chūō-Rinkan were opened. The Shin-Tamagawa Line officially became part of the Den-en-toshi Line on August 6, 2000.

Through service was extended beyond Suitengūmae to Oshiage on March 19, 2003, allowing through service with the Isesaki Line and Nikkō Line of Tobu Railway.

Tokyu plans to expand the line to four tracks from Futako-Tamagawa to Mizonokuchi. Almost all trains of the Ōimachi line are planned to run through this section to Mizonokuchi. The corporation has already announced that it will begin this service on June 2009, postponed from fiscal 2007. Ōimachi line express trains, which are 6-car sets, will then run between Ōimachi and Mizonokuchi.[2]
