diesel 10 (human)

In Thomas and the Magic Railroad, Diesel 10 was an evil, villainous, manipulative, mischievous and ravenous diesel engine who basically acted like a tyrannical boss-like figure to Splatter and Dodge. He absolutely despised steam engines, would call them taunting names like "Puffball", "Teapot" and "Tin Kettle" and was not above doing anything to get rid of them if possible. He is Sodor's strongest (but not quite largest) diesel, his power being enforced by his slightly malfunctioning claw, Pinchy. He can use this deftly, and was even able to use it to make a sculpture. Pinchy, though, seems to have a mind of its own, as it has been shown to "punch" Diesel 10 in the face from time to time, which he loathes. All engines, steam and diesel alike, fear or respect him.

Diesel 10 is based on a British Rail (BR) Class 42 diesel-hydraulic engine with an added non-regulation hydraulic claw. All but two members of the class were named after Royal Navy warships, so they, and the similar Class 43 (not to be confused with the InterCity 125 power cars with the same class number), were nicknamed "Warships". Two of these engines are preserved, D821 Greyhound and D832 Onslaught.
