Thomas'DayOff78.png

Dennis is a lazy diesel. He has a twin named Norman.

Bio

When Dennis was new to the railway, he tried to take advantage of Thomas. He soon learnt his lesson when he reversed into a ditch. With Thomas' help he was able to finish his work and promised to be a Really Useful Engine from now on.

In The Great Discovery, Dennis and a number of other diesels later waited in the quarry yard to hear if Thomas had been found in the days leading up to the reopening of Great Waterton.

Personality

Dennis is considered to be a very lazy diesel who tries to take advantage of others and depend on them to do his work. Dennis will often create excuses to get out of work, but usually gets caught in his lies, and always says sorry - but whether or not he means it is the question.

Basis

Dennis is based on No. 11001, a Bulleid diesel built at Ashford Works, England in 1949 and scrapped in 1959. He also carries his basis' number.

Livery

Dennis is painted grey with dark grey wheels and roof and red buffer beams.

Trivia

  • The fact that Dennis and Norman are twins is thought to be impossible as No. 11001 was the only one of its type built. However, this dilemma has also been shared with Skarloey/Talyllyn and Rheneas/Dolgoch.
