Strange predictions of trains with wings and propellors - demonstrated on model railway.
Introductory intertitle: "With the successful trials of the rapid "Zepp train", Germany is experimenting further with various units to ascertain the most efficient shape for high speed transit."
High angle shot of a model railway. A strange space age style vehicle is placed on the track - very rounded shape with a bullet shaped front. "Bodies and tracks may vary, but they all rely on propellers for tractive effort and speeds of 150 miles an hour are prophesied."
A man pushes a strange vehicle along the track - it is a cross between a plane and a train - very weird and pretty comical. The vehicle begins to run along the track on its own power - it is a train with wings! It races a train - and wins. Various shots of the new vehicles passing in between modern trains - strange!
