The Victor/Vulcan 2994-6 locomotives were ordered by the Steel Company of Wales (SCOW) for their Abbey, Margam and Port Talbot works in 1950. They had a whole range of advanced features, such as 18" X 26" cylinders, together with piston valves, roller-type big-end and side-rod bearings, manganese steel axle-box and horn plate liners, hopper ashpans, self-cleaning smokeboxes, rocking grates and Lambets wet sanding. Steel fireboxes were used as well as "Owens" patent poppet valve and balanced regulator valves though surprisingly the locomotives weren't fitted with superheating. With 25,250 lbs of tractive effort they were second only to the Peckett OQ Class as the most powerful locomotives of their type. In later life 2994 and 2996 were sold to Austin Motor company and were named 'Victor' and 'Vulcan' . They ran until 1972 when the locomotives were preserved on the West Somerset Railway and currently run at the Stephenson Railway Museum and the Lakeside and Haverthwaite Railway. 2995 was sold to NCB at the same time for use at a colliery and was scrapped in 1967.
