Many years ago, I went on a day trip from Bristol to Lundy Island. The coach which took us to Weston, departed from near the old Bristol Docks, where I noticed this very unusual "ladies loo". It was unusual to see an old trolleybus in those days, whoever thought of converting it to a toilet, I wonder? If all the "seats" were taken downstairs, perhaps a voice would shout "plenty of room upstairs".
