On March 12th, I also photographed Tokyu 5050 Series 4110F "Shibuya Hikarie" set.
On that day, the train was in service as an "F Liner" train for Hanno, which operates only twice on the morning of Saturdays, Sundays, and holidays.
"F Liner" train for Hanno used to operate many times on weekdays, Saturdays, Sundays, and holidays before 2022. However, all "F Liner" trains toward Seibu Ikebukuro Line on weekdays and the daytime on Saturdays, Sundays, and holidays are shortened to Kotesashi Station.
From March 18th, 2023, "F Liner" for Hanno does only once on Saturdays, Sundays, and holidays, as well as a rapid train for Shin-kiba.
