Harvey is a tank engine with a crane mounted on top of his boiler, which makes him look rather unusual.
All the engines except Thomas teased Harvey at first, but when he was able to rescue Percy after an accident, they realized that his difference was what made him special. Since then, he has proved very useful, using his crane arm for maintenance, building and clearing up.
Harvey is a kind, friendly and hard-working crane engine. He enjoys helping out when his friends are in distress.
With perhaps the most distinctive appearance of any engine, Harvey is painted burgundy with yellow lining and brown square buffers. His name and the number "27" are written on both sides in yellow, however, the "27" is painted on his crane.
Harvey is based on Dubs Crane Engine No. 4101, nicknamed "Dubsy".
