Here we have two forms of railway transport in an active image.
I’ve always liked photos that show transport on two levels (or more). This photo worked out well. I caught a tram passing below a steeple-cab electric in suburban Prague in early June 2000.
What makes the whole image more interesting is the tram passenger flagging the car to stop. This puts a bit life in the photo.
Incidentally, if you haven’t been there, Prague is one of the great tram cities, and offers endless opportunities for photography.
