The Skarloey Railway bought two worn out Hunslet Diesels from the National Coal Board and, using parts from both engines, constructed Fred. He was put into service in 1989 as a secondary Diesel and is used mainly for maintenance and engineering work. Fred is lazy and tries to stay out of work by pretending to be ill. Rusty often has to pay the price. Once a year, Fred has to pull a slow train that spread weedkillers on the tracks.
