"Info on this article only applies to TME headcanon and how the character is used in the series, and does not entirely comply with lore and character development established in Thomas & Friends."

Diesel Electric Unit 69420 Mark 10, or Diesel 10 for short, is a recurring villain on the channel. Speaking with a gruff Russian accent, and having an unpredictable personality, Diesel is the perfect no-nonsense head of the Sudrian Mafia, someone The Fat Controller is even afraid of. But despite this hard exterior, Diesel has slowly gone insane, developing schizophrenia, and talking to his claw as if it was a real person, even going so far as to give it a name, "Pinchy".
