Notes: Powerful 4-4-0 engines originally built from 1930 for the Hastings line to replace L class locomotives and other earlier 4-4-0s, they has quite restricted dimensions and weight, but were an outstanding example of compact 3-cylinder design. The class proved capable of handling express trains of around 12 carriages on various Southern Region routes. 30900/1/7/9/13-15/17-21/24/29-31/33-34/37-39 were later fitted with multiple jet chimneys. With nearly the steam-raising capacity of the 4-6-0 'King Arthur' class, these engines sometimes produced remarkable performances, able to sustain over 70mph with heavy trains on level track. SR 903 was built at Eastleigh in 1930 and is seen here in early-mid 1930s form without smoke deflectors in olive green with a train of Maunsell carriages. In BR days she was based in Kent and latterly Nine Elms before withdrawal in December 1962.
