Chuo Sobu Line

Overview
The Chūō-Sōbu Line (中央・総武緩行線, Chūō-Sōbu-kankō-sen) is a railway line that runs through Tokyo and Chiba Prefecture, Japan.

Chūō-Sōbu Line is part of the East Japan Railway Company (JR East) network, but it operates on separate tracks along the right-of-way of the Chūō Main Line (Chūō Line (Rapid)) and Sōbu Main Line (Sōbu Line (Rapid)).

The term Kankō (緩行, lit. "slow run") distinguishes local trains on the Chūō-Sōbu line from rapid service trains running on the Chūō Main Line between Mitaka and Ochanomizu and on the Sōbu Main Line between Kinshichō and Chiba.
