The Hunslet engine company built 69 0-6-0 diesel shunters between 1955 and 1961. They worked on the Eastern and Scottish regions of BR, although most had a very short service life due to a surplus of shunters at the time; only one survived to receive a TOPS number. Heljan's model (item no. 25921) is beautifully decorated with superb cab detail and excellent running qualities.
