Rosie is a lavender tank engine.
When Rosie first arrived on Sodor, she followed Thomas around and wanted to be just like him, much to Thomas' annoyance. However, he was glad to see her after he got stuck in a land slide whilst taking some birthday mail to Alice.
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. Rosie could be described as a feisty, energetic tomboy who is not afraid to work hard.
Rosie is painted lavender with grey tank panels, gold boiler bands, and red detailing on her wheels and metalwork.
