Daisy is a diesel railcar. She was designed by Metro-Cammell and built at Washwood Heath in 1960. 


After Thomas was sent to the Works to have his bufferbeam repaired in 1961, Daisy was loaned from the B.R. 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 sideplates and cowcatchers and claimed that one only needed to "toot and look them in the eye" to shoo animals. This, of course, was proved false when Daisy tried to shoo an inquisitive bull. The Fat Controller discovered that Daisy was lazing about, but gave her a second chance after Daisy helped clear up the mess made when Percy collided into a train of stone. Daisy promised to change her ways.

In 1962, Mavis sought Daisy's advice about how to show Toby that her method of doing things was correct. This wasn't exactly the best move, as Daisy knew next to nothing about trucks.

In 1963, Daisy was not Pulling Troublesome trucks because they were mean  and she only likes passengers

In 1975, Daisy was given the Harwick branch line after its construction to run passenger trains while Ryan was in charge of goods traffic.

In 1990, Daisy was put in charge of Thomas' fast run to Knapford while Thomas was in York. Daisy later 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, Daisy was given charge of a special train to bring guests to Knapford for the welcome-home party, but was delayed after running over some cones left inside the crossing gates at Dryaw crossing. She only just made it in time.

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

In 1995, Daisy was stranded on the mainline 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.


Daisy is based on a BR/Metro-Cammell DMU Class 101/102, approx. 57 ft long. She is, however, a one-off, being a single railcar (akin to the Class 121 ' bubble cars') instead of the traditional two. She has recently been rebuilt as a 2-car set formation, like a regular British Rail Class 101. Although normally considered to be a Class 101, Daisy is always depicted with the distinctive valances around the bufferbeams that distinguishes the lightweight prototype units.


Daisy is painted green with yellow lining, similar to the livery of the British Railways DMUs in the 1960s. She wears makeup, including eyelashes, red lipstick, blush and blue eyeshadow. She has a grey face.
