Tobu Skytree Line
The Tobu Skytree Line (東武スカイツリーライン, Tōbu Sukaitsurii-rain) is a Japanese railway line operated by the private railway company Tobu Railway, extending from Asakusa Station in Tokyo to Tōbu-Dōbutsu-Kōen Station in Saitama Prefecture. Some trains from the line continue to the Tokyo Metro Hibiya Line and Tokyo Metro Hanzōmon Line. Previously named the Tobu Isesaki Line, this section was rebranded the Tobu Skytree Line on 17 March 2012 in conjunction with the opening of the Tokyo Skytree tower.
Note that Oshiage Station is officially an extension or part of Tokyo Skytree. The double tracks between Oshiage and Hikifune are thus the third and fourth tracks of the Tokyo Skytree − Hikifune section.
All-stations "Local" services operate from Asakusa to Kita-Senju, and Tōbu-Dōbutsu-Kōen, and onward to Minami-Kurihashi on the Tōbu Nikkō Line. Some peak-hour Local services from Asakusa terminate at Takenotsuka, Kita-Koshigaya, or Kita-Kasukabe.
The Skytree Line has trains that inter-run with two Tokyo Metro subway lines. One is the Tokyo Metro Hibiya Line connected at Kita-Senju, with all-station stop "Local" trains only. The other is the Tokyo Metro Hanzōmon Line at Oshiage, running as either local, semi-express or express trains within the subway line and the Tokyu Denentoshi line. Beyond Shibuya, the terminus of the Hanzomon Line, nearly all trains continue to and from the Tokyu Den-en-toshi Line, down to the terminus of Chūō-Rinkan.
To the north, trains run via the Yagan Railway to the Aizu Railway's Aizutajima Station.
Stops and operated sections are as of 2013.
