Two years later, the LSWR would be amalgamated into the Southern Railway as part of the Grouping Scheme, creating the “Big Four”.

The first batch of LSWR’s S15 locomotives was 16-strong and finished production by May 1921. The result rolled out of Eastleigh Works in February 1920 as the S15 Class, and it was quickly established that this locomotive would be a very successful worker. With a more modern requirement - that would see a locomotive capable of serving south coast ports and running express dairy trains in and out of London - still in place, Urie changed key aspects of his H15 Class to produce a freight-dedicated locomotive. Urie’s original mixed-traffic H15 design, which helped the LSWR in the midst of the war effort, would serve as the basis for his future locomotives. The S15 Class was originally formed from the mind of the London & South Western Railway’s Chief Mechanical Engineer, Robert Urie, as there was a need for a new locomotive to fulfil heavy freight duties in the early 1920s.
