When people sit on the top level of the double-decker bus, they can see a lot of the city while they ride. They might see famous buildings and parks, and even some famous sites like Big Ben or the London Eye along the river. However, they would not see the underground tunnels of the Tube because the train travels below the city. Using buses and trains also helps the environment in some ways because many people can ride together instead of everyone driving their own car, which can reduce pollution. Overall, public transportation helps a large city like London move millions of people every day while trying to balance convenience and protect the environment.
