Biography

Thomas & Friends

When Dennis was new to the railway, he tried to take advantage of Thomas by getting him to do all his work for him. 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 then on.

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

Stories From Sodor

Season 1

It was revealed that Dennis regularly works on the Norramby Branch Line, alongside Emily, Molly, and Neville^[1].

Season 2

Dennis was seen at Knapford when Sir Topham Hatt announced the arrival of the Qua dru ple ts^[2].

Amazing Adventures

Like in the television series, Dennis tried to take advantage of Thomas by getting him to do all his work for him and soon learnt his lesson when he reversed into a ditch^[3].

Stories of the Sophomores

Dennis, alongside Mavis, Diesel, Diesel 10, Salty, 'Arry and Bert, was seen at Ffarquhar Quarry waiting to hear if Jacob had been found^[4].

Season 10

Dennis later hit a fallen tree after Sidney forgot to warn him^[5].

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 prototype Bulleid diesel built at Ashford Works, England in 1949 and scrapped in 1959. He also carries his basis' number. Norman is also a member of this class.
