Rosie is an dock tank engine that works at Knapford Harbour on Thomas' Branch Line. She also assists Percy with the branch's freight traffic.



Rosie is a friendly, respectful and helpful tank engine. She and Thomas like to have fun and also like to help each other when they are doing work, though her admiration of him occasionally get on his nerves. Rosie could be described as a feisty, energetic tomboy who is not afraid to work hard and get dirty.


Rosie is painted lavender with light grey tank panels, gold boiler bands, red lining and red wheels. The number "19" is painted on the sides of her tanks in yellow.

She was originally painted USATC black with white lettering and numbering. On the SR, she was painted SR black with yellow lettering and numbering. On British Rail, she was painted in BR's Departmental Malachite livery.
