Den

Den is a big diesel-hydraulic engine who runs the Vicarstown Dieselworks with his assistant, Dart.

Personality
Den is the diesel engine who runs the Vicarstown Dieselworks, repairing 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diesels for fixing them with a whisk of his wheels, even if his tools may be old and shoddy and his machinery may be outdated. Although he is trustworthy and authoritative, Den may have the occasional chuckle at an engine's expense.

Basis
Den is based on a Rolls Royce Class 4DH Sentinel diesel-hydraulic 0-4-0. These engines were bult to replace Sentinel's steam line for use in various industrial shunting roles. Larger 0-6-0 and 0-8-0 variants were also produced. Several engines of this type are preserved, including one at the National Railway Museum, and another at the Bluebell Railway.
