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 learned 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 diesel engines were waiting in the quarry yard upon hearing that 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.

Season 2

Dennis was seen at Knapford when Sir Topham Hatt announced the arrival of the Quadruplets.

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.

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.

Season 10

Dennis later hit a fallen tree after Sidney forgot to warn him.

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 instead. Dennis will often create excuses to get out of work and is infamous for the fact that, unlike most of the engines on Sodor, he does not make an effort on being really useful, and slacks off on a regular basis. As a result of his laziness, he is very unpopular with other engines, but they are forgiving enough to let him redeem himself, depending on how motivated he really is. He 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 British Rail (BR) 11001, a prototype Bulleid diesel built at Ashford Works, England in 1949 and scrapped in 1959. He also carries his basis' number. Dennis' twin, Norman, is also based on BR 11001.

Dennis' basis

Livery

Dennis is painted two-tone grey with dark grey wheels, gearboxes, roof, and front. His number 11001 is painted on his sides in white, and his jackshaft is red.
