"Hippsche Wendescheibe", an old type of Swiss main signal, between Neuthal and Bauma on the
DVZO museum railway from Hinwil. Back side of the signal in "stop" position, showing a big
white disk (which means that the trains of the opposite direction must 
stop - to trains seeing the backside the signal is not relevant, they 
can pass it).
