I'm sure they could learn something from JR East's and Toei's operations in Tokyo.The extent of Tokyo subways running over commuter rails is most impressive. This Polish map (to scale) shows which subway lines are have reciprocal operation along JR East and private railways. "It has been a generally followed principle that, to simplify operation, metro should be totally separated from other types of railways. In Tokyo however, by the end of the 1950s it was decided to connect metro lines with regional railways of many types: Private and National (main line). In this way Subway acquired access to outgoing lines, while regional railways received cross-city links. This was attempted not long after similar reciprocal working in London or some American cities had been eliminated." In fact nine subway lines (out of twelve) are extended to run over commuter rail at one or both ends. Some of these extensions go as far as the 60 km radius, but none splits into more than two branches at the same end except line A which splits into four. Line A (Asakusa) extends from Misakiguchi and Haneda airport (Keikyu) to Imba-Nihon-Idai and Narita airport (Keisei). Line H (Hibiya) extends from Kikuna (Tokyu) to Tobu-dobutsu-koen (Tobu). Line T (Tozai) extends from Mitaka (JR East) to Toyo-katsutadai (Toyo) and Tsudanuma (JR East). Line I (Mita) extends to Musashi-Kosugi (Tokyu). Line N (Namboku) extends to Urawa-misono (Saitama). Line Y (Yuracucho) extends to Hanno (Seibu) and Shinrin-koen (Tobu). Line C (Chiyoda) extends to Karakida and Hon-atsugi (Odakyu). Line S (Shinjuku) extends to Hashimoto and Takao-sanguchi (Keio). Line Z (Hanzomon) extends from Chuo-rinkan (Tokyu) to Minami-kurihashi (Tobu). London's planned Crossrail, which will have 24 tph and two branches at each end, is similar in principle to a Tokyo metro line extended at both ends over commuter rail. Thameslink 2000 is a cheaper but bigger project, with two northern branches and twelve southern branches including some 100 km long. I don't think that's realistic. I am sure that London could learn plenty from Tokyo. Better timekeeping for instance! |
