History: 

Built in October 1941 at the Sothern Railway’s Eastleigh Works, ‘Cunard White Star’ was the fourth of Oliver Bulleid’s exciting and radical new 30-strong ‘Merchant Navy’ Class, designed for top-link express passenger work. The new locomotives had many innovations, such as chain-driven valve gear that was lubricated by means of an oil bath, electric lighting, one piece Firth-Brown driving wheels, and the distinctive air-smooth casing. The unusual French-style number 21C4 was replaced by the BR number 35004 in October 1949, following nationalisation of the railways. Rebuilt in July 1958, it was eventually withdrawn from Bournemouth shed in October 1965 and scrapped by Cohens at Eastleigh shed in 1966.
