Bilevel car

A bilevel car is like a big bus or train that has two levels for people to sit in. When you get on a bilevel car, you can either go up the stairs to the top level or stay on the bottom level. Each level has seats for people to sit and look out the windows. Bilevel cars are used for things like commuter trains or long-distance travel because they can fit a lot of people and make efficient use of space. Basically, it's like a two-story building on wheels!
