The {{nihongo|'''Tōyō Rapid Railway Line'''|東葉高速線|Tōyō Kōsoku-sen}} is a [[rapid transit]] line owned by the [[Public-Private_Partnerships_In_Japan|third-sector]] company Tōyō Rapid Railway Co., Ltd., which runs between [[Nishi-Funabashi Station]] in [[Funabashi, Chiba]] and [[Tōyō-Katsutadai Station]] in [[Yachiyo, Chiba]]. The name {{nihongo|Tōyō|東葉}} comes from the characters for Tokyo and Chiba. The line functions as an extension of the [[Tokyo Metro Tōzai Line]],<ref name="terada2013">{{cite book| last = Terada| first = Hirokazu |title = データブック日本の私鉄 |trans-title=Databook: Japan's Private Railways| publisher = Neko Publishing| date = 19 January 2013| location = Japan| page = 56| isbn = 978-4-7770-1336-4}}</ref> with a [[through service]] between the two lines.
Of the 16.2km line, approximately 5.9 km (37%) is in underground tunnel, 9.5 km (59%) is on bridges (viaducts), and 0.8 km (4%) is elevated.
==Operation==
Every train on the Toyo Rapid Railway (other then depot workings between Yachiyo-Midorigaoka and Toyo-Katsutadai) operates a [[through service]] with the [[Tokyo Metro Tōzai Line]].<ref>{{Cite web |title=駅案内・時刻表 ｜ 東葉高速鉄道 |url=https://www.toyokosoku.co.jp/station |access-date=2024-09-13 |website=www.toyokosoku.co.jp}}</ref> However, as Tōyō Rapid Railway rolling stock (the [[Tōyō Rapid 2000 series]]) is not equipped with [[ATS-P]], they must terminate at [[Nakano Station (Tokyo)|Nakano]] and cannot continue onto the [[Chūō–Sōbu Line]], which uses ATS-P. Similarly, the Chūō–Sōbu Line's [[E231-800 series]] sets must terminate at [[Nishi-Funabashi Station|Nishi-Funabashi]] as they lack the WS-ATC safety system the Tōyō Rapid Railway Line uses. Tokyo Metro vehicles can operate on all three lines.
===Current train services===
There are three train service types on the Tōyō Rapid Railway, however all trains stop at every station the Tōyō Rapid Railway Line. As such, the service type only refers to the stops made on the Tokyo Metro Tōzai Line.
====Rapid (快速)====
Operates between [[Tōyō-Katsutadai Station|Tōyō-Katsutadai]] and [[Nakano Station (Tokyo)|Nakano]] (the western terminus of the Tōzai Line), with some services extending to [[Mitaka Station|Mitaka]]. The majority of services on the Toyo Rapid Railway use this service. While it stops at every station on the Tōyō Rapid Railway Line, the section between [[Nishi-Funabashi Station|Nishi-Funabashi]] and [[Tōyōchō Station|Tōyōchō]] on the [[Tokyo Metro Tōzai Line]] is non-stop except for a stop at [[Urayasu Station (Chiba)|Urayasu]], then the service stops at all stations west of Tōyōchō. Most morning and afternoon trains go direct to Mitaka on the [[Chūō–Sōbu Line]].
====Commuter Rapid (通勤快速)====
Like the Rapid Service, it also operates between [[Tōyō-Katsutadai Station|Tōyō-Katsutadai]] and [[Nakano Station (Tokyo)|Nakano]] stations and in the morning and afternoon to [[Mitaka Station|Mitaka]], and stops at every station on the Tōyō Rapid Railway Line. Only operates in the "up" direction on mornings towards Nakano. It is non-stop between [[Nishi-Funabashi Station|Nishi-Funabashi]] and [[Urayasu Station (Chiba)|Urayasu]] before stopping at every station west of [[Urayasu Station (Chiba)|Urayasu]].
====Local (各駅停車)====
This service only operates on rush hours when services on the [[Tokyo Metro Tōzai Line]] make through services with the Tōyō Rapid Railway Line, and sometimes goes to [[Mitaka Station|Mitaka]] station on the [[Chūō–Sōbu Line]]. This service stops at all stations on the Tōyō Rapid Railway Line, [[Tokyo Metro Tōzai Line]] and the [[Chūō–Sōbu Line]].
===Former services===
====Tōyō Rapid (東葉快速)====
From the revised timetable on the 4 December 1999, the "Toyo Rapid" service was created. It stopped at [[Nishi-Funabashi Station|Nishi-Funabashi]], [[Kita-Narashino Station|Kita-Narashino]], [[Yachiyo-Midorigaoka Station|Yachiyo-Midorigaoka]] and [[Tōyō-Katsutadai Station|Tōyō-Katsutadai]]. Due to congestion on tracks, on March 14, 2009, the timetable changed to have 4 evening "up" bound Tōyō Rapid trains, thus the "down" service towards [[Tōyō-Katsutadai Station|Tōyō-Katsutadai]] was abolished. Due to passenger counts increasing on stops that the Tōyō Rapid did not stop at, the Tōyō Rapid service was completely abolished on the March 14 2014 timetable change.
==Stations==
* All services stop at every station.

==History==
Construction work on the line commenced in July 1984, and the line was fully opened on 27 April 1996.<ref name="terada2013"/> Limited-stop {{Nihongo|"Toyo Rapid"|東葉快速|Tōyō Kaisoku}} services were introduced on the line from the start of the 4 December 1999 timetable revision. Such services in the "up" direction (toward Tokyo) were discontinued in 2009, and the "down" limited-stop services were discontinued from the start of the revised timetable on 15 March 2014.<ref name="railfan20140315">{{cite web |url= http://railf.jp/news/2014/03/15/195500.html|script-title=ja:東葉快速が廃止される|trans-title=Toyo Rapid discontinued|date= 15 March 2014|location= Japan|language= ja|access-date= 15 March 2014}}</ref>
