Combination bus

Picture a big yellow school bus that picks up lots of different kids from different neighborhoods and takes them all to school together. Now imagine that instead of just one bus, there are lots of different buses that all come together and connect to make one big bus, kind of like a Lego tower. This is called a combination bus.

With a combination bus, lots of different buses can work together to transport even more people than just one bus could handle. Each of the smaller buses might pick up kids from different areas or have different routes they follow, but when they all come together, they form a really big transportation system that can get lots of people where they need to go. It's kind of like how putting all your Legos together can make a bigger and more awesome creation than just using one set.
