Rosie (Thomas the Tank Engine)

Rosie is a pink tank girl engine a number 19 on The Fat Controller's railway. She's young and tries to copy Thomas, to his displeasure. She is voiced by Teresa Gallagher in UK, and Jules de Jongh in US.

During an autumn storm, Thomas was supposed to deliver a train to High Farm. Rosie wanted to help, but Thomas left on his own. Rosie followed him down the line, so Thomas decided to take the shorter, more dangerous route, thinking that Rosie would not follow him. Thomas ended up trapped in an avalanche, but was thankful to see Rosie going by on the other line. Rosie took the train to High Farm, and then brought back the farmer's daughter Alice, who thanked Thomas.
