|The Hunslet Diesels|
The Hunslet Diesels are two old worn-out narrow gauge diesel engines.
Not much is known about them, they used to work for the National Coal Board and were later sold to the Skarloey Railway to work there. The diesels were later scrapped and some of their parts were used to build Fred. The Hunslet Diesels are presumed to be painted in a black coat of paint, with bright red side rods, just like their basis.
