京濱東北線
Most Keihin–Tōhoku Line trains have a through service onto the Negishi Line between Yokohama and Ōfuna stations. As a result, the entire service between Ōmiya and Ōfuna is typically referred to as the Keihin-Tōhoku—Negishi Line() on system maps and in-train station guides. Keihin-Tōhoku Line—Negishi Line trains are recognizable by their light blue stripe (the line's color on maps is also light blue).
