BoCo is a diesel who was built in September 1958 and arrived on Sodor in 1965 to work on Edward's Branch Line. He is a wise and kind diesel who loves to work.


Once BoCo came to the North West Railway, he had to deal with Bill and Ben's nonsense as they played a trick on him. Edward soon settled them and told them about BoCo. Then, he threatened to take away the cars he had bought for them when they were teasing Gordon, back when the big engine wandered down Edward's branch. Edward and BoCo then became friends. Since then, he has worked on the Wellsworth-Brendam Bay Branch.


BoCo is based on the BR Class 28 diesel-electric engine, famous for its Co-Bo wheel arrangement.
