Key to symbols The Sōtetsu–JR Link Line is a section of the Eastern Kanagawa Rail Link project, built by the Japan Railway Construction, Transport and Technology Agency (JRTT).

This service is publicly referred to as a Sotetsu Link Line by JR East,[1][2][3] and as a JR Link Line by the Sagami Railway (Sotetsu).

The service shares the same route as the Shōnan–Shinjuku Line, heading inbound towards Musashi-Kosugi, Ōsaki, Shibuya, and Shinjuku.

This requires trains to cross over level junctions to enter Tōkaido Line tracks near Tsurumi or Shinagawa (or somewhere in between), which would possibly undermine the high density train operations in this section, if no dedicated grade separation is built.
