Butch 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 Brendam Docks after he broke down. He also helped with the demolition of Tidmouth Sheds and the rebuild of Great Waterton. He is now part of the Search and Rescue Team. Butch broke down and needed to be towed to the Sodor Search and Rescue Centre by Flynn. Butch towed Flynn to the Rescue Center when he got a flat tire when racing to a fire. He later told Flynn about the fire at Brendam Docks, and encouraged him to fight it.
