The is a railway line that runs through Tokyo and Chiba Prefecture, Japan. Part of the East Japan Railway Company (JR East) network, the line operates on separate tracks along the right-of-way of the Chūō Main Line (Chūō Line (Rapid)) and Sōbu Main Line (Sōbu Line (Rapid)), providing service between Mitaka Station in the cities of Mitaka and Musashino and Chiba Station in Chiba.
The term distinguishes local trains on the Chūō-Sōbu line from rapid service trains running on the Chūō Main Line between Mitaka and and on the Sōbu Main Line between and Chiba.
All through service trains enter the Tōzai Line at either Nakano, or Nishi-Funabashi. These trains operate within the following routes:
Certain limited express and seasonal trains run through, or stop at stations on this line. For information on the Shinjuku Wakashio and the Shinjuku Sazanami that make stops on the Chūō-Sōbu Line at, see their respective articles.
At around 9 -10pm, a few westbound trains headed beyond Mitaka onto the Chūō Line (Rapid), with some terminating at Musashi-Koganei, and the others at Tachikawa. The other trains during the hour operated regularly.
At around 4 - 6am and 11pm - 1am, Chūō-Sōbu Line services were divided at Ochanomizu Station, into two sections.
This service pattern last operated on 13 March 2020. To prepare for the eventual installation of platform doors on Chūō-Sōbu Line platforms and the future addition of Green Cars on the Rapid line, Chūō Line Rapid service trains no longer regularly operate on the Chūō-Sōbu Line tracks.[2]
