トップハム・ハット卿
Thomas arrived on Sodor shortly after he was built in 1915, when The Fat Controller bought the locomotive for a nominal sum to be a pilot engine at Vicarstown. Thomas was used initially as a station pilot engine in the first three stories in book 2, but longed for more important jobs such as pulling the express train like Gordon; his inexperience prevented this. In the fourth story, "Thomas and the Breakdown Train", Thomas rescues James and is rewarded with his own branch line.
