Lady/Tasha is a Red tank engine who works on the NWR
Lady is friendly and kind, sometimes cheeky to the engines. Even though she got Diesel into a serious accident, she is still kind and helps all engines. She is also very flirty and loving towards Adam when they become a couple and is very suspicious if she sees other female engines happy around him, leading her to be jealous as shown with Alice when they had a small pep talk about him.
