Campo is the third of railway barges in Big city port. He is used to carry coal cars though. The reason is if coal tips out of the cars trenches along the rail beds catch it. He is mostly pulled by Zink. Campo is a crued barge with tricky mind. And never likes to be pulled along side Frank and Eddie, who allways annoy him. He is a distant cousin of S.C. Ruffy, the Sodor private owner wagon.
Sometime before 1941, Campo caused a bad acident and was rebuilt as a Zinc barge for the Lake Bigg mining operation. He still caused trouble, and often complained about not being loaded fast enough. After he was nearly sunk by some trucks, he was towed to a beach and turned into a children's playground.
