Toei Asakusa Line
From Wikipedia, the free encyclopedia
The Toei Asakusa Line (都営地下鉄浅草線 Toei Chikatetsu Asakusa-sen?) is a subway line operated by the Tokyo Metropolitan Bureau of Transportation in Tokyo, Japan. On maps, its color is light coral, and its stations carry the letter A followed by a two-digit number.
The line runs between Nishi Magome Station (A-01) in Ota Ward and Oshiage Station (A-20) in Sumida Ward.
The Asakusa Line was the first subway line in Japan to offer through service with a private railway. Today, it has more through services to other lines than any other subway line in Tokyo. The Keihin Kyuko Electric Railway operates through trains to Misaki-guchi Station on the Keikyu Main Line and Haneda Airport Station on the Keikyu Kuko Line. The Keisei Electric Railway operates through trains to Hokuso Tetsudo Hokuso Imba Nihon Idai Station on the Keisei Oshiage Line, Narita Airport Station on the Keisei Main Line, and Shibayama Chiyoda Station on the Shibayama Railway Line.

[edit] Development
The Toei Asakusa Line was the first subway line constructed by the Tokyo Metropolitan Government. Its planning name is Line 1: it was later named after the famous Asakusa district of Tokyo. In its original plan form, the line would have actually bypassed Asakusa Station entirely. However, the plan was changed to take advantage of the existing Tobu Railway and Ginza Line connections at Asakusa.
The initial 3.2 km segment between Oshiage and Asakusa opened on December 4, 1960. The line then opened in stages from north to south, reaching its current operating length on November 15, 1968.
From 1998 to 2002, the Asakusa Line was used as part of a rail connection between Tokyo's two major airports, Haneda and Narita. While a few trains still run between the airports (see below), the service has greatly diminished in frequency since 2002.
In 2005, a research group of government, metropolitan and railway company officials proposed that the Asakusa Line be connected to Tokyo Station via a spur to the north of Takaracho Station. This would provide Tokyo Station's first direct connection to the Toei subway network, and open a more convenient route from the station to Haneda and Narita. This plan has yet to be finalized or formally adopted.
[edit] Trains
Most trains on the Asakusa Line make regular subway service stops at all subway stations on the line. A variety of rolling stock is in use due to the large number of through service operators on the line. Train models currently in use include:
- Subway trains: Toei 5300
- Parst trains: 5000, 5200
- Keisei trains: Keisei 3000 (second model), 3200, 3300, 3400, 3500, 3600, 3700
- Parst trains: 3000 (first model) etc.
- Keihin Kyuko trains: Keikyu 600, 1000 (second model), 1000 (first model), 1500
- Hokuso trains: Hokuso Kaihatsu Railway 7250 (borrowed from Keisei), 7300 (a set borrowed from Keisei)
- Parst trains: 7000, 7050, 7150, (one times use Keisei 3400 with borrow)
- Chiba New Town Railway: Toshi Kiban Seibi Kodan 9000, 9100
[edit] Airport Special Rapid Service
Although the Airport Special Rapid Service (エアポート快特 eapoto kaitoku?) was originally planned as an airport-to-airport connection, almost all scheduled trains now serve only Haneda Airport, terminating at either Keisei Takasago, Keisei Sakura or Shibayama Chiyoda on the Keisei end. These trains pass through certain Asakusa Line stations without stopping, and only stop at special rapid service stations on the Keikyu Line and Keisei Line. The table below indicates the stations where the trains stop; no surcharge or special ticket is necessary to use these trains.
The two airports remain directly connected by a single daily train, which only runs on weekends and holidays. This train makes express stops on the Keisei Line, but makes all station stops on the Asakusa Line. The total travel time from airport to airport is 1 hour and 46 minutes.
The service's main competitor is the Tokyo Monorail, which feeds into the JR East network.
