The official Thomas & Friends website have now added a character involved in the Day of the Diesels special into the Engine Depot.
Den will be introduced in the upcoming special where he already has appeard in the Fifteenth Series which was broadcast early in the UK.
Den's description reads; 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!
Another Day of the Diesels character will be added onto the Engine Depot in a month's time.
Day of the Diesels premieres later this Autumn.
