## Biography

### *Thomas & Friends*

In Day of the Diesels, Den and Dart took Thomas to the back shed of the Dieselworks while Percy, Diesel 10 and the other diesels took over the Steamworks.

In the fifteenth season, he, along with Dart and Diesel, tried to find a Christmas tree for the Dieselworks whilst in competition with Thomas. Den later teased Flynn for spraying the Fat Controller and Gordon.

In the sixteenth season, he helped Thomas fix Ol' Wheezy and repaired Gordon's bufferbeam.

In the seventeenth season, Den, with Dart, help fixed a splutter in Salty's engine.

In the eighteenth season, Den, along with Dart, Sidney, and Diesel hid from Paxton, causing Paxton to search for them.

In the nineteenth season, he was sent to the quarry as a replacement for Mavis while she was at the Dieselworks. Initially, Den struggled with the troublesome trucks, but after some encouragement from Toby and Henrietta, he toughened up and finished his job. When Mavis came back, Den went back to the Dieselworks.

In The Great Race, Den, along with Dart and Paxton, was part of Diesel's plot to be taken to The Great Railway Show. Diesel had the three put under crates in a large train, making them resemble vans. When the Fat Controller was in the final stages of choosing who would go to the show, Diesel would then honk his horn to signal the three to start pushing, making it look as if Diesel was moving the train by himself, whereas the other three diesels would actually be doing most of the work, which Diesel hoped would convince the Fat Controller to take him to the show. The day before the show, Diesel refused to move his train from blocking all ways in and out of the yard, leading Thomas, who was in a hurry to demonstrate his shunting skills to convince the Fat Controller to enter him in the shunting competition, to move Diesel's train himself. When he whistled after a shunter coupled him up, the diesels mistook the tank engine's whistle as Diesel's horn and started pushing the train as they were instructed to. Thomas was surprised

## 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.

## Technical Details

### 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.

Den's basis
### Livery

Den is painted slate grey and orange with cream lining. His buffer beams are painted with orange and black wasp stripes. He has the Vicarstown Dieselworks logo on each side of his cab.
