Fred is a diesel working on the Skarloey Railway.
In the 1980's 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.
Once a year, Rusty and Fred have to pull a slow train that spreads weedkillers on the tracks. One holiday weekend, he pretended to be ill so he would not have to pull the weedkilling train. So Rusty had to pull the train for him. For unknown reasons, he and Rusty did not attended Ivo Hugh's naming party.
