After hearing how the other engines of the Steam Team mention how fast and strong they are, Rebecca decided that she would leave the stations early to prove how she can get things done fast. Her first job was to pull the express, though she caused a small mishap when she accidentally collected Flying Scotsman's passengers at Vicarstown early. Rebecca first arrived on the Island of Sodor after Henry moved out of Tidmouth Sheds and Sir Topham Hatt wanted another engine to help with Gordon and the Express, though she arrived a day earlier than what Sir Topham Hatt expected and nearly bumped him and Winston off the rails when she tried to stop at Knapford.
