- "That's it. I need a vacation."
- ―Cranky, Swan Dive
Cranky is a green, grumpy and sleep-deprived crane that works at Brendam Docks.
When Brendam Docks' shipping company was expanding, they needed another crane, so Cranky came to Sodor. However, Cranky immediately felt hot, bothered and claustrophobic in the busy dockyard, so he took out his anger on the other engines, namely Thomas and Percy who were helping out from the Branch Line. When a storm arrived, Cranky managed to save Gordon, James, Duck, and the other big engines, who were stationed in a freight shed until further notice when the roof caved in, but not before Cranky toppled over onto the tracks in front of Thomas and Percy! The little engines helped the crane to be uprighted again, but Percy accidentally caused Cranky to topple over again when the crane seemed ungrateful for the little engines's actions. Since then, Cranky has been careful not to make fun of Thomas and Percy, but is still cranky all the same!
Much to the chagrin of the other engines, Cranky is "Cranky by name, and cranky by nature", as Salty would say. Cranky is often perturbed by the presence of other around him, sometimes calling them "bugs" or "mites" as a way of getting on their nerves from high up in the sky. He can try to be helpful on occasions, but those are rare, rare occasions indeed.
