Thomas the Tank Engine Wikia

Norman is an orange diesel with a unibrow. He is often seen working around Vicarstown. He is Dennis' twin.


Norman was one of the diesels who took over the Sodor Steamworks. He later laughed at Flynn for not being able to rescue Thomas. Norman told Percy that Sidney had been on his hoist for two years and was there when he was given his new wheels. He also offered Thomas and Gordon a place to sleep at Vicarstown Dieselworks when the turntable at Tidmouth Sheds was frozen. When Gordon refused the offer (due to the fact he hates the smell of the oil), Thomas was left to sleep there.

Norman was at the Dieselworks when Paxton returned after looking for him, Diesel, Sidney, Den and Dart.

When the Great Railway Show was being held, Norman was one of the engines who were hoping to be picked to compete but wasn't. Norman was later involved in an accident with Thomas, resulting in the tank engine being unable to compete in the Great Railway Show until he had to.

Sometime later, he helped the other diesels do the steam engines' work when the coal delivery was delayed.

Then, Norman was one of the diesels who got into trouble by not doing their jobs properly due to Diesel playing a trick on Rebecca so she could do the jobs and end up in the wrong place.


Norman's shape resembles that of his twin Dennis, but he is a diesel engine who is much kinder and more willing to work. He wants to be liked by all the engines, whether they be steam or diesel engines. So he does his part at the Sodor Dieselworks and follows all of his orders; in fact Norman is so efficient, Sir Topham Hatt holds him in high regard.

However, poor Norman often breaks down and he does not like that. Unlike Dennis (who is lazy), if Norman were fixed properly he would show what a Really Useful Engine he can be. He is also willing to help another engine in trouble.

Technical Details


Norman is based on British Rail (BR) 11001, a prototype Bulleid diesel built at Ashford Works, England in 1949 and scrapped in 1959. Norman's twin Dennis is also based on BR 11001. While the two co-exist in the television series, in the real world only one engine of this type was ever built, which Dennis bears the number of.


Norman is painted orange-red with two yellow stripes and red wheels with grey rims. He has a dark grey front, roof, toolboxes and footsteps. His running board and bufferbeams are red. His paint is chipped in places and shows signs of weathering.

In his initial appearances, Norman had a red jackshaft, however since the seventeenth series it has been painted black.
