Den is a large diesel-hydraulic shunter and the main engine at the Vicarstown Dieselworks.



Den is the diesel engine who runs the Vicarstown Dieselworks, assisting in the repair of the other diesels. He is stately and deeply pensive. He tries to make sure everything he says is deeply considered, can often be heard muttering "what I mean to say is...", and can tend to over-think. He may come across as a little slow, but nothing could be further from the truth. He is rather astute and likes to take into account as much as he can with regards to a problem. Although he is not a worrier, he may tend to be on the fence about taking particular action over a matter before making a calculated, informed decision that will be worth the wait. Sometimes though, Dart, his assistant at the Dieselworks, can tell what he is thinking and cut to the chase a little quicker for the benefit of the other engines, which is why they support each other so well as a team. Den is a hard worker and is popular and well respected among the diesels for helping to fix them. Although he is not devious, Den may have the occasional chuckle at another engine's expense.


Den is painted slate grey and orange with cream lining. His buffer beams are painted with orange and black hazard stripes. He has the Dieselworks logo on each side of his cab. The number "D11" is painted on his sides in white.
