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.


Rapid (快速)

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, Kita-Narashino, Yachiyo-Midorigaoka and 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 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.

Limited-stop 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.
