Shonan-Shinjuku Line

E231 train as Shonan-Shinjuku Line train at 2nd track of Shinjuku Station

The Shonan-Shinjuku Line (湘南新宿ライン, Shōnan Shinjuku Rain^?) is a railway line in Japan that connects the cities of Saitama, Tokyo, Yokohama, Kamakura, and Odawara. It is not a distinct railway line, but rather a 78 km composite line formed by portions of the Takasaki Line, Utsunomiya Line, Saikyo Line, Yokosuka Line, and Tōkaidō Main Line.

Trains

Initially, services were operated using a mixture of rolling stock, including 115, series, 211 series, 215 series (double-deck), E217 series, and E231 series EMUs, but rolling stock was standardized on the E231 series EMUs in 2004, from which date these trains also included two bilevel Green cars.

The following types of services run on the Shonan-Shinjuku Line:

• Local trains (普通, Futsū^?)

Local trains go from the Utsunomiya Line through the Shonan-Shinjuku Line to the Yokosuka Line and vice versa, making all station stops.
