Artist's commentary
Hang in There, Kogasa-san 2013
The Japanese reading for the place would be "Enteiho-eki", apparently.
These girls are characters from KRT Girls (Onward, Takame Girls! in Japanese), and there's a variety of them: a station attendant, a train operator, a mechanic, and so on. They're so cute!
Personally, I like the mechanic girl bcough cough
