Boco

Boco is a diesel who works on both the Mainline and the Brendam Branch Line. When he first came to the Island, the engines were not trustworthy of diesels after a certain devious diesel caused chaos on the railway, especially Gordon, Henry, James, & Duck. Edward was more kind and gave the new diesel a chance. After learning about Boco and seeing how nice he was, the engines accepted the big diesel and they're now firm friends. Boco is a very strong diesel and will do anything to help his friends. Boco also is one of the other engines who can handle the cheeky China Clay Twins, Bill & Ben.
