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 SR USA class.
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 was originally painted lavender with grey tank panels, gold boiler bands, and red detailing on her wheels and metalwork. Currently, Rosie is now painted cherry red with dark raspberry tank panels with the letters “NWR” written on them in light grey, gold boiler bands and light grey lining. She has gold lining above her wheels and around her ladder. She also has the number "37" in light grey under her cab windows. Rosie also still has her original red wheels with light grey wheel rims.
