Butch

Butch, also known as the "Sodor Heavy Recovery Unit", is a breakdown vehicle.

Bio
Butch is kept busy clearing rubble, towing broken-down or stranded vehicles or assisting in engine rescues. He also helped with the demolition of Tidmouth Sheds in "Calling All Engines". He keeps to himself, and thus doesn't speak much. However, he does have a big heart and is willing to help out engines and vehicles in distress.

Appearances
Butch first appeared in the fifth season with no dialogue, or, for that matter, no face. He has made cameos in every season since. However, he does speak on a Leap Pad book called, "Thomas the Really Useful Engine", and he is saying, "Hi. I'm Butch, the breakdown truck." Butch never made a speaking role in the tv series since his introduction.

Basis
According to the official website, Butch was constructed out of parts from a diesel, a lorry and a crane. He is based on a Scammel tank recovery vehicle converted to breakdown truck.

Livery
Butch is painted yellow with navy flatbed with "Sodor Heavy Recovery Unit" on both sides in white.

Butch's beard
Butch was the first non-human character in the television series to have facial hair. He has a small patch of beard.
