Tōyō Rapid Railway Line
railway line in Japan
The Tōyō Rapid Railway Line (東葉高速線, Tōyō Kōsoku-sen) is a rapid transit line owned by third-sector railway company Tōyō Rapid Railway Co., Ltd. The line connects Nishi-Funabashi Station in Funabashi, Chiba and Tōyō-Katsutadai Station in Yachiyo, Chiba. The name Tōyō (東葉) comes from the characters for Tokyo and Chiba. The line functions as an eastern extension of the Tokyo Metro Tōzai Line, 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 on embankments.
Operation
Every train on the Toyo Rapid Railway (other than depot workings between Yachiyo-Midorigaoka and Toyo-Katsutadai) operates a through service with the Tokyo Metro Tōzai Line. However, as Tōyō Rapid Railway rolling stock (the Tōyō Rapid 2000 series) is not equipped with ATS-P, they must terminate at 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 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.
