Somewhere in my vast collection of souvenirs that happened to fall off a wall and into my luggage, while traveling around the UK and Europe, is a sign:
"Passengers will please refrain from flushing toilets whilst the train is standing at the station platform."
Back in the 70's, I was traveling by train in Sweden and had to make use of the facilities. While standing at the commode, I felt a great wind. I looked down through the commode and saw the track ties going by. Different... BTW, they also had a sign on the door to the restroom to not use it when in the station!
