Den is a diesel who runs the Dieselworks… when Diesel 10 is not around. While he isn’t devious, he is still a diesel. Den is a hard worker and popular among the Diesels. He is very thoughtful and thinks hard before he speaks. When Den does speak it is very slowly. This gives the appearance that he may be a little slow, but nothing could be further from the truth. Engines can wait a long time for Den to give his insight, but it is worth the wait!
Den is based on a 0-4-0 Rolls Royce Sentinel.
