Keiyō Line

From Wikipedia, the free encyclopedia

The Keiyō Line (京葉線, Keiyō-sen^?) is a 43 km 1,067 mm (3 ft 6 in) gauge railway connecting Tokyo and Chiba, Japan, running mainly along the edge of Tokyo Bay. It is operated by the East Japan Railway Company (JR East).

It is the main rail access to the Tokyo Disney Resort and the Makuhari Messe exhibition center. The terminus at Tokyo Station is located underground, some distance to the south of the main station complex about half way to Yūrakuchō Station. This means transfer between other lines at Tokyo Station can take between 15 and 20 minutes.

The name Keiyō is derived from the second characters of the names of the cities linked by the line, Tōkyō (東京) and Chiba (千葉). It is occasionally confused with the Keiō Line, a different railway line in western Tokyo.

[edit] History

The Keiyō Line was initially planned as a freight-only line. Its first segment opened in 1975 as a link between the Chiba Freight Terminal Station (now the Mihama New Port Resort between Inage-Kaigan and Chiba-Minato Stations) and the JFE Steel factory near Soga Station. Passenger service began in 1986 between Nishi-Funabashi and Chiba-Minato, and was extended eastward to Soga and westward to Shin-Kiba in 1988.

The final segment of the Keiyō Line, between Tokyo Station and Shin-Kiba, opened in 1990. The platforms at Tokyo Station were originally built to accommodate the Narita Shinkansen, a planned (but never built) high-speed rail line between Tokyo and Narita International Airport.

Planners originally envisioned the Keiyō Line interfacing with the Rinkai Line at Shin-Kiba, thus providing a through rail connection between Chiba and the Tokyo Freight Terminal Station in eastern Shinagawa, and also completing the outer loop for freight trains around Tokyo formed by the Musashino Line. This original plan would also allow through service with the Tōkaidō Main Line, allowing freight trains from central and western Japan to reach Chiba and points east.

However, in the 1990s, as the artificial island of Odaiba began developing as a commercial and tourist area in the middle of the Rinkai Line route, the Rinkai Line was re-purposed for use as a passenger line. While there is a through connection between the Rinkai Line and the Keiyō Line, it is only used by passenger trains in charter service, usually carrying groups to the Tokyo Disney Resort.
