Passenger train toilet

When you go on a really long trip on a train and you need to go potty, there's a special little room called a toilet that you can use. Inside the toilet, there's a seat with a hole that you sit on, just like at home. But instead of flushing with water like you might have at home, there's a small button or lever that you push that makes everything go away. The toilet wastes go through pipes underneath the train and are stored in a special tank until the train gets to a station where they can be properly disposed of. It's important to make sure you only go potty in the train toilet and not on the floor or anywhere else on the train!
