In order to cope with the steadily increasing weight of express passenger traffic on the Southern Railway in the early years of Grouping, Richard Maunsell, the Chief Mechanical Officer, needed a locomotive that was more powerful than the King Arthur class, but one that would still conform to the various gauging and weight issues within the region and still be capable of hauling 500 ton trains at a speed of 55mph.The new Lord Nelson design had to fit within the profile of the King Arthur class and having previously used a Drummond four cylinder locomotive as a test bed, Maunsell altered the positions of the cranks on the Lord Nelson design to give eight exhaust pulses per revolution, rather than four.


The resulting increase in power over the two cylinder design of the King Arthur class was significant. A longer, Belpaire boiler, with a completely differently designed firebox was used, the cab design was similar to the L1 4-4-0 and the bogie was of a new design, being independently coil-sprung.Maunsell decided to produce one example as a prototype, ordered from Eastleigh Works on May 29, 1925, which replaced the last engine on an existing King Arthur build order. The locomotive, No. E850, was completed on August 11, 1926 and after trials at Eastleigh, was sent to Nine Elms for trial running on the Western section mainlines to Bournemouth, Portsmouth and Exeter, before moving across to Battersea for trials on the Dover boat trains.


Although areas for improvement were noted, there was enough confidence in the locomotiveing design for a further fifteen engines to be ordered; ten on March 13, 1927 and a further five on March 23, 1928. These locomotives were completed at Eastleigh between June 1928 and November 1929 and once the decision was taken to name the class after naval leaders, the Southern Railwaying publicity department went to work promoting the introduction, basing their claim of the class being the most powerful express locomotive in Britainin
