The ancient Mach-1 Skytrains in Vancouver. The front and back of each car have a small door, and when looking at that in combination of the shape of the train around that door, it looks just like an outhouse. Not only that, it has been known in the past and still occurs occasionally, to function as one, where people will use the space of where the fold down seats are just behind the small door, to take a poo poo!

These old poop poo trains are also known as boobie trains, crying trains, chicken slaughter trains.
1. Oh no, I just got poop-sandwiched by the poop poo train, had I been a little earlier or later to arrive at the station I would have boarded a Mach2 or Mach3 train!

2. If you see a pair of jeans, clothing, or bag left behind at the "outhouse area" of the poop poo train, do not touch it! It is likely to be covering up someone's turd!

3. Guess the people who designed the train wasn't paying attention to prevent it from becoming a poop poo train!!!

Mr. Hanky: "Poo-choo trian's layin' down its tracks, with a POO! CHOO! all the way and back!"

Eric Cartman: "Poo-poo train is my favorite thing! Spreading Christmas joy as we ride and sing!"

Mr. Hanky: "Christmas time wouldn't be the same, without hugs and kisses and a poo-choo train."

When sitting on the porcelain throne, preparing to drop some deuces a steady stream of fart air emits from your bunghole, sometimes pinched enough to emit a squeaking or whistling sounding fart announcing the turd train a'comin until the poo seals off the space and stops the whistle
Fuck dude, i could hear your poo choo train comin down the tracks from out here
