Butch, also known as the "Sodor Heavy Recovery Unit", is a breakdown vehicle. He is kept busy in construction areas, clearing rubble, towing broken-down or stranded vehicles, or assisting in engine rescues.
Butch first appeared towing Lorry 3 to the docks after he broke down. After that, he received many cameo appearances. He also helped with the demolition of Tidmouth Sheds in Calling All Engines! and the rebuild of Great Waterton in The Great Discovery. He is now part of the Search and Rescue Team. In the fifteenth season, he was given a magnet. In the sixteenth season, Butch broke down and needed to be towed to the Search and Rescue Centre by Flynn. In the seventeenth season, Butch towed Flynn to the Rescue Center when he got a flat tyre when racing to a fire. He later told Flynn about the fire at Brendam Docks, and encouraged him to fight it.
Butch is serious about his job and loves working, especially with his railway friends. Despite his size, Butch has a kind heart and is always ready when his service is needed.
Butch is based on a Scammel tank recovery vehicle. According to the official website, he was constructed out of parts from a diesel, a lorry, and a crane.
Butch is painted yellow with a navy flatbed and "Sodor Heavy Recovery Unit" written on both sides in white. Since the opening of the Sodor Search and Rescue Centre, he has the logo of said establishment on his cab doors.
