The JR Yamanote Line is suspending operation on the inner and outer loops from around 5:30 pm for inspection of the substation.
Due to this effect, the up and down lines between Omiya Station and Osaki Station on the Saikyo Line, some sections of the Shonan-Shinjuku Line, and the Sotetsu Line, which operates directly with the Yamate Line, are from Shinjuku to Hazawa Yokohama-Kokudai Station. The up and down lines between them are not driving.
In either case, there is no prospect of resumption.
