Daisy

Daisy is a diesel rail-car who works on Thomas' Branch Line

Persona
Daisy is a diesel rail-car, who has been known to consider herself "highly sprung, and right up to date!" She was brought to help run passenger services on Thomas' branch line, while Thomas was "indisposed" after running into the stationmaster's house. She can be hard to please, most indignant, and highly opinionated. She is confident in herself and can sometimes boast of her abilities in particular situations, unconcerned, despite having never actually been in such a position before. She will sometimes presume she can show other engines a thing or two, despite knowing little on the matter, until she actually learns for herself.

After arriving on Sodor, Daisy insisted that she required delicate handling and considered pulling trucks and vans to be below her. She was very lazy and stubborn, but the Fat Controller spoke severely to her, telling her that his engines must work hard and that he sends lazy engines away. However, working hard after Percy got himself into a predicament, the Fat Controller felt she deserved another chance. Daisy is now good friends with the other engines on Thomas's branch line, tries to work much harder to be a useful engine, and is better capable of handling things alone.

Basis
Daisy is a BR/Metro-Cammell DMU Class 101/102. She is, however, a single rail-car instead of the traditional two-piece unit.
