Locomotive Magazine, September 1904

Starting in 1863, Sharp, Stewart & Co. not only delivered some goods locomotives with a 0-6-0 wheel arrangement to the newly founded Cambrian Railways, but also twelve locomotives with a 2-4-0 wheel arrangement. The driving wheels were not particularly large at 66 inches, but they were used for passenger and express trains. Although relatively small for their time and not particularly fast, the engines were richly decorated with large amounts of brass. From 1890 they were fitted with a new boiler and a driver's cab. Two locomotives were converted to tank locomotives from 1908.
