Richard Maunsell was the Chief Mechanical Engineer of the South Eastern and Chatham Railway and later the Southern Railway from 1913 to 1937. During that time he designed the N, N1, U1 class 2-6-0 mixed traffic and passenger engines and the K1 and W class 2-6-4 tank engines seen above. Out of these six classes, only one N class engine is preserved at the Swanage Railway.
