ELI5: Explain Like I'm 5

Coach (rail)

A coach is like a big room on wheels that carries people from one place to another on a train track. It is a long carriage with rows of seats on either side where passengers can sit and relax during their journey. Think of it like a bus, but instead of being on a road, it's on train tracks! Coaches can have different levels of comfort, and some may have things like air conditioning, toilets, and snacks available for the passengers. Train coaches are an essential part of train travel and help people get to their destination comfortably and efficiently.
