Barry is a BR Standard Class 2 engine. He is courageous, kind, and yet intimidating. He used to be very boastful and laid-back, but he realized that his work was not a game and needed to be taken seriously. He now loves to tell tales of his adventures when he used to work as a rescue engine in North Wales.
- Barry was originally set to be in the 39th volume of the original Railway Series, called Barry the Rescue Engine, but the volume was cancelled.
- He is named after Barry Island in South Wales, in which he was rescued from the scrapyard.
