The GNR Small Boiler C1 is the first 4-4-2 or Atlantic type in Great Britain. Designed by Henry Ivatt, 22 were built from 1898 at Doncaster Works. Known as ‘Klondykes’ (1897 Klondike gold rush) it appeared in 1888 in the US. A development of the 4-4-0 the additional trailing truck supported a larger firebox and improved riding. Ten years later Ivatt introduced the Atlantic type to Britain. Ivatt replaced Patrick Stirling, was revered for his locomotives. Seeking more power and adhesion, Ivatt took the American route. Number No.990, named for Henry Oakley, the general manager of the railway, it was shipped in 1898. Ivatt placed importance on boiler design. He opted for a large capacity vessel – the extra steam giving the Atlantics the edge over Stirling’s single wheelers. The Atlantics entered service in 1900 and proved fast and lively. Ivatt had to caution drivers to rein in speed on track between London and Doncaster too uneven for safety! In turn, the enginemen told Ivatt the cylinders were no match for the boiler. The first Atlantics had to be worked at uneconomic rates to achieve expected performance; they were thrashed. Ivatt attempted to rectify this by fitting superheaters.
