When Lily first arrived, Daisy was sent to show her around the Island. Lily made Daisy feel like she wasn't special or unique.
Lily is a proud engine. She is very arrogant and, like Daisy, considers herself "highly sprung and right up to date".
Lily is based on the BR/Metro-Cammell Class 101/102 DMU. She is, however, a single railcar instead of the traditional two to four-piece units. These were one of the longest serving class of "First Generation" DMUs, with its service life of 47 years only being replaced by the Class 121. A total of 41 cars are preserved.
Lily is painted yellow with red lining. She also has gold buffers and a black roof.
