JR Saikyo Line train services

The JR Saikyo Line is classified as a commuter rail service, meaning a passenger train service that connects suburbs and other towns to the major metropolitan area of Tokyo. As such, its trains run slower than some other services, with maximum operating speeds between 90 kilometers (56 miles) and 100 kilometers (62 miles) per hour.

Three service types operate on the JR Saikyo Line:

  • Local trains, or kakueki-teisha, trains stop at all stations along the route.
  • Rapid trains, as well as Commuter Rapid trains, omit certain stations, thus quickening the pace of the journey.
  • Commuter Rapid services operate only during the rush hours. Some cars are designated as women-only during these times as well.

Main connections

JR Seikyo Line connects with the JR Yamanote line in Osaki Station, Ebisu Station, Shibuya Station, Shinjuku Station and Ikebukuro Station.

Some trains continue past the terminal stations of the JR Saikyo Line. For example, some transfer to the Kawagoe Line at Omiya Station and continue as far as Kawagoe Station. Southbound trains may travel past Osaki Station using the Rinkai Line, which is operated by the Tokyo Waterfront Area Rapid Transit, toward Shin-Kiba Station. Others may continue to Ebina Station using the Sotetsu Main Line.

The JR East Tokyo General Rolling Stock Centre is located at the link between the Rinkai and Saikyo Lines. There, train cars for the Yamanote Line are stored.
