京濱東北線
The Negishi Line does not exist as an independent service. Nearly all passenger trains are operated through onto the Keihin-Tōhoku Line past Yokohama to , , and ; 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).
