Following "Iketama Happy Train", I photographed Sotetsu 20000 Series on Tokyu Toyoko Line and Sotetsu 21000 Series on Tokyu Meguro Line.
Since March 2023, going-through service trains toward Toyoko Line or Meguro Line via Tokyu Shin-yokohama Line have been in service.
This time, I could shoot pictures of 21000 Series 21106×8 set on Meguro Line and 20101×10 set on Toyoko Line. The trains through Meguro Line mainly operate between Ebina Station and Nishi-takashimadaira Station on Toei Mita Line or Urawa-misono Station on Saitama Railway Saitama Stadium Line. Those through Toyoko Line do between Shonandai Station and Wakoshi Station on Tokyo Metro Fukutoshin Line.
I hold complex feelings of surprise and sensational at the going-through service because I can see Sotetsu carriages in Tokyo Metropolitan Area and Saitama Prefecture.
