Diesel

Diesel is one of the first diesels on Sodor. Diesel is devious, manipulative, and very troublesome. He blamed engines for accidents and caused many more. Diesel was sent away, sent back, and sent away again by The Fat Controller until at one point he stayed permanently. Diesel now is less devious, but still plays tricks to haunt the other engines. He one day knows that all his tricks will get back on him someday.
