Daisy

Daisy was built especially for service on the Ffarquhar Branch Line. After Thomas was sent to the Works to have his bufferbeam repaired in 1960, Daisy arrived to do his work. Daisy was nasty to Henrietta, Annie and Clarabel, refused to sleep in the Ffarquhar engine sheds on the grounds that it was "smelly" and blatantly refused to pull freight because it was "bad for her swerves". Daisy later called Toby cowardly for having side plates and cowcatchers and claimed that one only needed to "toot and look them in the eye" to shoo animals away. This, of course, was proven false when Daisy tried to shoo an inquisitive bull named Champion and ended up being humiliated. The Fat Controller discovered that Daisy was lazing about and spoke to her sternly, saying that lazy engines were not welcome on his railway, but he gave her a second chance after Daisy helped clear up the mess made when Percy crashed into a train of stone. Daisy promised to change her ways.

In 1962, after Douglas claimed all diesels were "devils", Percy used Daisy as an example of a good diesel to try and change his opinions about them.

Once, Mavis sought Daisy's advice about how to show Toby that her method of doing things was correct. This was not exactly the best move, as Daisy knew next to nothing about trucks.

In the latter half of 1990 and the former half of 1991, Daisy was put in charge of Thomas' fast run to Knapford while Thomas was in York, because of her hard work she was given the number 14. Daisy later that year claimed that she was not afraid of snow, but changed her mind after getting stuck in a snowdrift for a week.

When Thomas finally returned from York, he helped with building of the Harwick Branch Line and when it was completed, Daisy was transferred there to manage its passenger trains, with Ryan managing the goods. 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 on Thomas' Branch Line, as passenger services on the Harwick line dried up in the winter and Thomas was on quarry duty. 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.

In 1993, Daisy - along with Thomas, Percy and Toby - saw Wilbert off when he returned to Gloucestershire.

While the Railway was preparing for the Golden Jubilee of the Railway Series in 1995, Daisy became stranded on the Main Line when the stretch before Dryaw was declared unsafe as rabbits had burrowed beneath it and so she was given the task of ferrying passengers from the airfield to Knapford. She later tried to cheer Henry up when he started to worry about the Golden Jubilee.

In 2007, Daisy teased Percy for being afraid of grass snakes but was humiliated when she blew a fuse out of fright when a crate of eels dropped beneath her.

In 2011, Daisy attended the ceremony where the bust of the Thin Clergyman was unveiled at Tidmouth.
