Daisy is a diesel railcar on the NWR. She currently works on passenger services on Thomas' branch and sometimes takes the milk.
Daisy was built by 1960 and was sent to Sodor to assist on the Ffarquhar branch while Thomas was at the works. At first the railcar was hard to please for Toby and Percy, they had to soothing Henrietta, Annie and Clarabel there feelings after Daisy say rude things about them. The next day Daisy was coupled up to milk van and wasn't too pleased about it, She then blew her fuse while shuddering and said her fitter told her that she was not allowed to pull anything and so was uncoupled from the van, Daisy then rolled away happy as can be.
When Percy had his predicament The Fat Controller souled Daisy for her lazy and rather rude altitude but gave Daisy another chance and nowadays Daisy is more polite to the engines.
One day she came across a steam lorry named Elizabeth and both didn't get on well until Elizabeth slipped on some oil and crashed into a milk tanker that Daisy was pulling. the steam lorry soon apologized for her rudeness and she and Daisy are now firm friends.
Daisy was stubborn, hard to please and lazy. She can be boastful about being highly sprung and up to date but after Percy's Predicament she has became a more hard working and reliable engine!
