- “There's room for another engine at the Dieselworks, if one of you wants to sleep there.”
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 a place to sleep at the Dieselworks when the turntable at Tidmouth Sheds was frozen.
When the Great Railway Show was being held, Norman was one of the engines who were hoping to be picked to compete, but he wasn't picked. Norman was later involved in an accident with Thomas, resulting in the tank engine being unable to compete in The Great Railway Show.
Sometime later, he helped the other diesels do the steam engines' work when the coal delivery was delayed.
Norman's shape represents his twin Dennis, but he is a much kinder diesel engine. 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. 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.
Norman is based on the Bulleid Diesel prototype, No. 11001. Dennis is also based on this locomotive.
Norman is painted orange-red with yellow lining and a dark grey roof.
