George is a grumpy steamroller whose interactions with engines generally lead to trouble. He is owned by the Sodor Island Council.

George is a grumpy, bad-tempered and rude steamroller. He is no friend of the railway, often heard rebelling that "railways are no good" and that they should be pulled up and turned into roads. George is happiest when he is rolling, but enjoys causing bother for the engines across the island too. He is grouchy, disagreeable and his unpleasant attitude and stubborn nature are often the cause of chaos and disruption, an example being when he crashed into Sir Handel's train for calling him a "great clumsy road-hog".
