On old stock years ago before the introduction of retention tanks you would see a sign in the toilet cubicle saying ‘Do not use the WC while the train is standing in a station’ (or some such wording). Therefore if the train wasn’t moving you needed a frosted window with a clear peep hole to see if the train was stopped at a signal in the middle of nowhere or actually at a station. That way you could work out if it was safe to flush or not. It was an unspeakable crime to leave a pile of poo and Izal toilet paper on the tracks for the commuting public to see!
Nowadays a window isn’t essential but natural light from a window is so much more pleasant than artificial light plus a window makes the space feel larger and less cramped.
