Almost every train on the Toyo Rapid Railway makes Through Services with the Tokyo MetroTōzai Line. However, due to Tōyō Rapid Railway vehicles not being equipped with ATS-P, they can not operate on the Chūō–Sōbu Line, which uses this method of safety equipment. The same goes for E231-800 series sets, which can not go direct to the Tōyō Rapid Railway Line. Despite this, Tokyo Metro vehicles can operate on all lines.

Former services
Tōyō Rapid (東葉快速)
From the revised timetable on the 4 December 1999, a new service called the "Toyo Rapid" service. 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.
Construction workon the line commenced in July 1984, and the line was fully opened on 27 April 1996. Limited-stop "Toyo Rapid" services were introduced on the line from the start of the 4 December 1999 timetable revision, but such services in the "up" direction were discontinued in 2009, and the "down" limited-stop services were discontinued from the start of the revised timetable on 15 March 2014.
