Daisy
Daisy was built especially for service on Thomas' branch line. When she first arrived, she was highly strung and would only carry passengers because she felt she was too good to pull trucks. Daisy soon learned that all work is important on Sodor, and now helps out whenever she can.
Fun Fact
Daisy was brought to the Railway after Thomas broke through the Stationmaster's house and "visited him" for breakfast.
