Ichiban Densha ga Hashita is a Abe Hiroshi dorama special about the girls who drove the trams or roman densha during WW2 in Hiroshima and the first roman densha to run after the bombing. While it was a brezzy one hour, I wish they had let the old ladies do the talking with images and photos instead of dramatising the story.
I have a feeling that the anime short works better as a story than the dorama special. Watchable but I would not go out of my way.
