The E2 is based on the original LBSCR Class, more specifically the version with the extended side tanks, these 0-6-0 side tank engines were built at Brighton Works between 1913-1916 to replace the E1 Class.
They were used for shunting duties and short-distance goods trains in London and on the south coast, and last worked at Southampton Docks. They were withdrawn between 1961 to 1963. None were preserved.
Thomas is also based on this class, albeit with significant diffences.
The E2 is brown with yellow lining.
