One of a series of five volumes written and drawn by Ian Beattie reviewing steam motive power designs emanating from the four groups and British Railways. It sets out to identify and portray the various locomotive classes built – though not necessarily conceived – during the 25 years existence of the Southern Railway, from establishment in 1923 to dissolution in 1948. By means of scale drawings (4mm to 1ft), complementary photographs, biographical summaries and major dimensions, the information presented herein is directed towards rail enthusiasts of all ages and degrees of knowledge, with perhaps a bias towards those who are in the throes of building or already possess model railways, for whom the dimensional and allied details given should save much time and effort in researching their favourite S.R. engine. Locomotives included are Uire/Maunsell ‘King Arthur’ Class 4-6-0, 1924; Maunsell N Class 2-6-0, 1924; Maunsell L1 Class 4-4-0, 1926; Maunsell ‘Lord Nelson’ Class 4-6-0, 1926; Maunsell U Class 2-6-0, 1928; Maunsell U1 Class 2-6-0, 1928; Maunsell Z Class 0-8-0T, 1929; Maunsell V Class ‘Schools’ 4-4-0, 1930; Maunsell W Class 2-6-4T, 1931; Maunsell N15x Class 4-6-0, 1934; Maunsell Q Class 0-6-0, 1938; Bulleid Q1 Class 0-6-0, 1942; Bulleid ‘West Country’ Class 4-6-2, 1945; U.S.A Class 0-6-0T, 1946; Bulleid Rebuilt ‘Merchant Navy’ Class 4-6-2, 1941-1956.
