LB&SCR C3 class

The LB&SCR C3 class were ten 0-6-0 steam freight locomotives built in 1906 at Brighton Works to a design by Douglas Earle Marsh. They were made to haul the heaviest goods trains and to replace the older C2 class, but they ended up being less efficient and fairly fuel-hungry. Marsh preferred rebuilding the existing C2s into the C2X class rather than making more C3s, so the C3s spent much of their lives on secondary freight duties in mid-Sussex and earned the nickname “Horsham Goods” because seven of them were based at Horsham. The boiler Marsh designed for the C3 later saw more success on the SR Z class 0-8-0 of 1929. All C3s passed to the Southern Railway in 1923; two were withdrawn in 1936–37 during the recession, and the remaining engines lasted until after nationalisation, being withdrawn between 1948 and 1952. None were preserved.
