Then Thomas sneaks up and gives a cheeky whistle, telling Gordon to wake up and work harder and runs off, laughing. One day, Gordon returns from a long journey and wants a rest, so he finds a siding to sleep in.
Thomas likes to startle him rudely by teasing him with his loud whistle. Thomas thinks he works the hardest and is often very cheeky to the bigger engines, especially Gordon, the biggest and proudest engine who pulls the express. His job is to fetch coaches for the other engines and then take them away when the engines are done pulling them. Thomas is a blue tank engine who works at a big station called Knapford on a railway island named Sodor.
