Daisy

Daisy is a diesel railcar

Bio
Daisy's introduction in the television series was directly adapted from The Railway Series and happened virtually the same way. Her model was also used as a generic diesel in the fourth series.

During the steam and diesel engines rivalry, Daisy was one of the diesels who joined the meeting at the Coaling Plant and later helped Toby take the workmen to build the Sodor Airport.

Ever since the Harwick Branch Line was built, Daisy had been working on that line with Ryan, managing the passenger trains while he handles the goods, although she still helps out on Thomas' branch line if passenger duties are not too busy on her line.

Daisy regained her original attitude when she encouraged Ryan to help her out with some of her passenger duties, but her laziness backfired when Ryan took on even more of her responsibilities and ended up causing confusion and delay. Daisy apologised and agreed to do Ryan's extra duties for a while: taking trucks to and from the Quarry.

The Fat Controller asked Daisy to take some special passengers to the holiday town of Harwick, but she decided that they were so special that she did not want to allow children eating ice lollies on board and refused to pull a dusty baggage truck. However, these turned out to be the props and the audience. Without them, the puppeteers' Punch and Judy puppet show could not go ahead. With no time to go back to the station to get the props, the puppeteers put on their performance from one of Daisy's windows.

She was finally able to pull rolling stock without worrying about her swerves when The Fat Controller asked her to pull Annie and Clarabel during her help on Thomas' Branch Line. The coaches paid her back for saying rude things to them by convincing her she was falling apart when there was actually nothing wrong with her. However, their plan backfired as Daisy panicked and abandoned them with their passengers at Maithwaite so she could speak to a professional. She returned to Harwick soon after.

After years of scarcely no accidents, Daisy derailed when a bull blocked her way back to the Arlesburgh Yard Sheds and Judy and Jerome had to help her get back on the tracks.

Diesel damaged Daisy's springs when he bumped into her and later - thinking that she was asleep - explained that it is his way to make friends. Diesel later told her that Harvey was boasting about being unique, which caused trouble between the two engines. At Christmas, Daisy was upset that Christmas was not going out as planned.

Sometime later, a storm damaged the Harwick school and Daisy had to take them to Knapford school. She complained about it so Duck later found Dexter so she did not have to take the children.

Personality
Daisy is a diesel railcar, 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, mostly indignant, and highly opinionated. She is extremely authoritative, trustworthy, and 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, the Fat Controller felt she deserved another chance after she worked hard clearing up after an accident Percy had. Daisy is now good friends with the other engines on Thomas' Branch Line, tries to work much harder to be a Really Useful Engine and is better capable of handling things alone. Daisy can be described as a self-obsessed diva and also vain about not wanting her interior be dirty one bit.

Despite changing for the better, Daisy is still snarky and irritable. During the steam engines’ feud with the diesels, she temporarily sided with the diesels in their campaign to get rid of all of the steam engines.

In newer episodes, Daisy was heard speaking French, such as when she said "Merci beaucoup" (Thank you very much) to Den and Dart after she was repaired, and when she used the terms to describe the entertainers she was to carry to Duck and Oliver, which indicates that she has knowledge in the French language as well.
