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 Centre 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.
In the nineteenth season, Butch sprayed Thomas with mud after he got stuck while pulling a tractor. He also tried to move a whale back to the ocean but could not when it was discovered that the tide was too far out.
After Thomas had an accident, he derailed far away from the rails so he was pulled by Butch to the Steamworks. Butch later attempted to get Rocky back on the rails by himself, but only stopped when his engine was at risk of blowing out.
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 loosely based on a Scammell Pioneer heavy recovery vehicle and his front resembles that of a Scammell Constructor. According to the official website, he was constructed out of parts from a diesel, a lorry and a crane.
Butch's front is painted yellow and his trailer is painted navy blue, with "SODOR HEAVY RECOVERY UNIT" written on both sides in white. Since Misty Island Rescue, he has the logo of the Sodor Search and Rescue Centre on his cab doors.
