Chuo-Sobu Line: the Chuo-Sobu Line is a main east-west rail link in central Tokyo between Mitaka and Chiba.
The JR Chuo Main Line runs west from Tokyo Station all the way to Nagoya, and the JR Sobu Main Line runs east from Tokyo Station all the way to Choshi in Chiba Prefecture. Put together, they form an east-west commuter railway artery through the metropolis.However, there is a section of track, spanning five stations, north of Tokyo Station where neither the Chuo Line nor the Sobu Line run.
The JR Chuo-Sobu Line therefore spans the Chuo and Sobu lines for this stretch of five stations through which neither runs. Furthermore, between Mitaka in the west and Chiba in the east, the Chuo-Sobu line provides a rapid and local service for stations on these lines. The orange Chuo Line (Rapid) acts as the rapid service, and the yellow Sobu Line as the local service.
The trains that run on the Chuo-Sobu Line are differentiated by color: yellow is local and referred to as "Sobu Line," and orange is Rapid and referred to as "Chuo Line."
The Chuo-Sobu line's official name is Chuo-Sobu Kanko Sen, "slow-moving Chuo-Sobu line." That's because it provides stations on those two lines with a local (every-station) service in the form of the yellow (Sobu) line, while the orange (Chuo) line provides the express service.
The Chuo Main Line and the Sobu Main Line are "Rapid" (Kaisoku) lines for the length of the Chuo-Sobu Line, i.e., between Mitaka in the west and Chiba in the east. Past where the Chuo-Sobu Line stops, they change back to being "slow" (local) lines.
