About The Keihin–Tōhoku Line is a railway line in Japan that connects the cities of Saitama, Kawaguchi, Tokyo, Kawasaki, and Yokohama. It is part of the East Japan Railway Company (JR East) network. The line's name is derived from the characters for Tokyo (Japanese: 東京), Yokohama (Japanese: 横浜) and the Tōhoku Main Line (Japanese: 東北本線). The Keihin-Tōhoku Line officially follows portions of the Tōhoku Main Line and Tōkaidō Main Line. Between Ueno and Akabane stations the Keihin–Tohoku and Tohoku Main lines are physically separate and thus alternate routes. route length is 59.1 km (36.7 mi) with 36 stations.

tbh, not sure about 1970's era. For a Toyko route, people think of modernity and the present era with E233 works nicely with this.
