Pete is a new engine for Hiatt Grey's engines, he arrived from the Rheilffordd Gwili Railway to help out the engines. Mainly with Jenny. And once he arrives, Pete was shunting coaches, but then he starts to complain. But Rachel, helps him to take her good train and she can shunt coaches.
Pete is a shunter engine, he doesn't like freight cars laughing. He certainly complains about shunting coaches for the big engines. And he sometimes can be a little boastful, and claims he's not afraid.
- In a runnig gag, Pete normally calls the team "sissies" much to their hatred and annoyance.
