Data from E L Ahrons, The British Steam Locomotive from 1825 to 1925 (London: Ian Allan, 1926; and Graham Glover, British Locomotive Design 1825-1960 (London: George Allen & Unwin Ltd, 1967). See also steamindex at [], last accessed 28 June 2006
Unsuccessful stab by William Adams and his successor Massey Bromley at increasing the size of freight engines. Rather than supplanting smaller 0-6-0s, these Moguls -- the first of the wheel arrangement in Britain -- proved profligate coal burners, needed too much lubricating oil, and did not steam well. They were scrapped after only 6-8 years of service.
According to steamindex's review of Great Eastern locomotive designs, 572, the first of the class, was dubbed Mogul "...after the Great Moguls of Delhi, who at that time were much in the public eye. The name was painted on the large sandboxes which stood on the running plate above the middle pair of driving wheels ..."
(Locobase notes railroads and builders of locomotives using the same wheel arrangement in other countries such as the United States had given them the "Mogul" name as early as 1866.
