The Yokosuka Line connects Tokyo in Chūō, Tokyo and Kurihama in Yokosuka, Kanagawa. Officially, the name Yokosuka Line is assigned to the 23.9 km segment between Ōfuna and Kurihama stations, but the entire route is commonly referred to as the Yokosuka Line by JR East for passenger service.
The Yokosuka Line runs underground between Tokyo and Shinagawa (parallel to the Tōkaidō Main Line, the Yamanote Line and the Keihin-Tōhoku Line) then branches to the west along the Tōkaidō Shinkansen into the city of Kawasaki. (This alignment, technically known as the Hinkaku Line (品鶴線 Hinkaku-sen ), was originally built for freight usage; see below.) It rejoins the Tōkaidō Main Line corridor near Tsurumi Station and follows the Tōkaidō Main Line to Ōfuna, where it branches off to the southeast along the original Yokosuka Line toward the Miura Peninsula.
The limited number of stations along the route make the Yokosuka Line a de facto express route between Tokyo and Ōfuna, with trains regularly attaining 120 km/h.
Yokosuka Line local trains make all stops. Most trains have 11 cars, with two of those being Green cars. Other trains between Tokyo and Zushi are made up of 15 cars -- an 11-car set joined to a 4-car set. (Due to shorter platform length at stations south of Zushi, only 11-car trains are operated to Kurihama.) The Airport Narita rapid service operates as a local train within the Yokosuka Line.
Shōnan-Shinjuku Line local trains make all stops on the Yokosuka Line between Nishi-Ōi and Zushi.
Ohayō Liner Zushi and Home Liner Zushi commuter liners stop at the stations shown in the list below. The Ohayō Liner Zushi only boards passengers at Ōfuna, Kamakura and Zushi; the Home Liner Zushi only boards passengers at Tokyo, Shimbashi, and Shinagawa.

The Hinkaku Line (品鶴線 Hinkaku-sen ) was originally built to divert freight traffic from the busy Tōkaidō Main Line, providing an alternate route between Tokyo and Tsurumi. After a 1967 explosion, freight trains were banned from portions of the central Tokyo rail network, providing the impetus for the construction of the orbital Musashino Line. The new Musashino Line was connected to the Hinkaku Line roughly 6 km north of Tsurumi Station near Musashi-Kosugi, siphoning off nearly all freight traffic after its opening in 1975. This left a substantial chunk of the double-tracked, mostly grade-separated Hinkaku Line disused.
In order to put the line back into passenger service, a new 6 km track was installed between Tsurumi Station and the Musashino Line, where it was connected to the now-disused portion of the Hinkaku Line. Two new stations were constructed: one (Shin-Kawasaki) adjacent to the existing Kashimada Station on the Nambu Line in 1980 and another at Nishi-Ōi in 1986. Musashi-Kosugi Station, the third station in this section opened in 2010 and provides a transfer to the Nambu Line as well as the Tōkyū Tōyoko and Meguro lines.
The section between Yokosuka and Kurihama is single-tracked; trains can only pass one another at Kinugasa and Kurihama stations.
