The Southern Railway Class LN or Lord Nelson Class is a class of 4-6-0 steam locomotive. They were named after famous Royal Navy admirals. They were introduced in 1926, and for a time held the title of 'most powerful locomotive in Britain' (the claim being based on tractive effort). This led to the GWR introducing the King class to take the title back, as before the Lord Nelsons the GWR Castle class had held the title. The GWR claimed the King's were built to allow longer trains to be used, but considering they did not lengthen their platforms to match these lengthened trains until the mid-30's it is clear the Kings were simply a publicity exercise.
The Lord Nelson's had a very long firebox difficult for inexperienced firemen so as often as possible the Lord Nelson's had specific firemen. They were not thought of as very good steamers, until in 1938 Bulleid, Maunsell's replacement as CME of the Southern modified the Nelson's, giving them larger chimneys and lemaitre blastpipes. This transformed their performance.
One was involved in what could have been an extremely major accident in the early 30's- it's leading driving wheels jumped off the track and ran for many yards before amazingly rerailing themselves over a point without the crew's knowledge!
The LMS Royal Scot Class was loosely based on this class.
