Arthur was brought to Sodor by Sir Topham Hatt to pull freight and shunt around the yards. He found that he really enjoyed working with fish, and that he was just about the only engine that liked their smell. Because of this, Sir Topham Hatt sent him to work the coastal run, shuttling fish from Brendam Docks to the various stations of the island.
Arthur currently enjoys working the coastal run, as well as working at the Docks with Salty. He also is often called upon to do odd jobs, such as taking freight trains and passenger trains around the island if something happens to the regular engine.
Arthur is a friendly, obedient, intelligent, and cheerful tank engine. He has never been naughty and his held in high esteem by the other engines of Sodor. He is a hard worker and is always willing to help out a friend in need. He holds Hiro in high esteem as a mentor. He is good friends with James, BoCo, and Edward. If anything negative can be said about him, it can be said that he can be a bit gullible and can work himself so hard that he can fall asleep on the job.
