Diesel 10 is a villainous diesel with a roof-top and a hydraulic claw grabber named Pinchy. He mainly works in the lumber yards as a "Branch clearing specialist"


Diesel 10 is quite evil and mean, being confined to a single area of the island and not being allowed to access most of the rest of it. Even so, he does have a good side, as he helped the Flying Scotsman get to his welcome celebration, and this good behavior seems to have been recognized by the Controllers of Sodor, as he is seen working away from his normal area.
