The JR Joban Line is affected by a personal injury that occurred at Mikawashima Station, and after 3:00 pm, the rapid train runs from Shinagawa Station to Toride Station in Ibaraki Prefecture, and local trains stop between Shinagawa Station and Katsuta Station in Ibaraki Prefecture. I had to suspend the operation on the line, but I resumed the operation by about 4:22 pm.
