This class OY1 special class locomotive was built by Peckett & Sons in 1948 to work for Caurtaulds at Flint in North Wales. The locomotive was designed with a boiler pressure of 200psi and a tractive effort, at 85% boiler pressure, of 22,700lbf.
After it finished working at Flint it was donated to the Llangollen Railway Little or no work was done on the locomotive and it was sold for scrap to P. Dobbins (Chester) Ltd, who occupied the old steam shed at Mold Junction. Instead of being cut-up, the locomotive was stripped of all its copper/brass fittings etc and abandoned.
In 1986 the locomotive was purchased privately and in August of that year it was moved to Steamtown at Carnforth (now the home of West Coast Railways) for restoration to working order.
The locomotive was dismantled and completely rebuilt. During this time, a Kylepor exhaust system was designed and fitted to improve the steaming characteristics and a chime whistle has replaced the manufacturer’s original style. In addition, it was named ‘F.C. Tingey in honour of Fred Tingey, an ex-Barrow fireman who was one of the restoration team, but who sadly did not live to see the engine at work.
The locomotive moved under its own power for the first time in preservation in December 1999 and 24 hours later it left its restoration base for a new home at Kirkby Stephen East (Stainmore Railway).
In September 2002, 2084 appeared at the Corus 125 celebrations to mark 125 years of steelmaking at the Workington plant which has now sadly closed.
In May 2003 the locomotive moved to the Caledonian Railway at Brechin for what was intended to be just for the summer season. It soon became apparent that, with the very limited running that had been undertaken to date, attention was required to the axleboxes and this work was carried out during the winter of 2003-2004 with the help of the Caledonian Railway volunteers. The locomotive remained at Brechin for a further two years where it worked the passenger service until it returned to Kirkby Stephen East in December 2006.
The locomotive continues to be upgraded and recent work has seen the fitting of a new and much improved vacuum ejector system. It has recently been overhauled at Kirkby Stephen East where it returned to traffic in 2011 and is now operational.
Following a further overhaul the locomotive steamed again at Kirkby Stephen in August 2019.
