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). It connects the Sōtetsu Main Line to the JR East Saikyō Line, via the tracks of the Sōtetsu Shin-Yokohama Line and the Tōkaidō Freight Line. 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.[4] [5]
JR through service trains enter the Tōkaido Freight Line once leaving Hazawa Yokohama-Kokudai Station, via the Tokyo-side of Yokohama-Hazawa Freight Station, then enters the Yokosuka Line tracks near Tsurumi Station. The service shares the same route as the Shōnan–Shinjuku Line, heading inbound towards Musashi-Kosugi, Ōsaki, Shibuya, and Shinjuku.
Trains operate from Ebina on the Sotetsu Main Line, via Nishiya, Musashi-Kosugi, and enter the Saikyō Line at Ōsaki. Trains will mostly terminate at Shinjuku. In the morning rush hours, some trains go further north towards Musashi-Urawa, Ōmiya, Sashiōgi (where the Kawagoe Line depot is located), and as far as Kawagoe. A total of 46 round trips will be operated every day, with a rush-hour frequency of 4 trains per hour, and off-peak frequency of 2-3 trains per hour.[6]
The fastest travel times are 44 minutes between Futamatagawa and Shinjuku, 45 minutes between Yamato and Shibuya, and 36 minutes between Ebina and Musashi-Kosugi.
Past proposals also suggested Sōtetsu trains to operate through services with the Ueno-Tokyo Line, towards the Utsunomiya, Takasaki and Jōban Lines. 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. Thus the idea was scrapped due to these difficulties.
