Sgt Murphy was a Kerr Stuart 0-6-0T (3117 of 1918), one of a type developed for wartime use. After the First World War it was used by the Admiralty at Beachley Dock at Chepstow, Monmouthshire until being sold to deal A. H. Richards of Chepstow. It was acquired from Richards in 1921 by Penrhyn Quarry.
In 1932 Sgt. Murphy overturned in the quarry, killing its driver. It was rebuilt at the railway's Coed y Parc workshops in with the boiler lowered by more than 7 inches. It received a new firebox in May 1938 and new side tanks in 1945. In January 1955 it was officially noted as "scrapped" and left in the scrap line at Coed y Parc.
Sgt. Murphy was purchased by Messrs Pealling and Weaver and moved to Staffordshire in 1964, it was at Teddy Boston's Cadeby Rectory by 1976. In 1977 it arrived at the Betws-y-Coed Railway Museum. At the end of 1991 it went to Winson Engineering at Penrhyndeudraeth, where it was rebuilt as a 0-6-2T. By now in the ownership of the then General Manager Gordon Rushton it arrived on the FR in 1993.[video 1]
While on the Festiniog, it received the FR crest and featured in a number events including the 1993 Hunslet Hundred gala.
In July 1996 it was moved to the Teifi Valley Railway.
