Oliver Bulleid

Oliver Vaughan Snell Bulleid CBE was born in Invercargill, New Zealand, on 19 September 1882 to British immigrant parents. After the family's return to Britain and his education at Accrington Grammar School, he joined the Great Northern Railway at Doncaster in 1901 at the age of eighteen, as an apprentice under Henry Ivatt, the CME. A four-year apprenticeship was followed by appointments as assistant to the Locomotive Running Superintendent and, a year later, manager of Doncaster Works.

He served in the Royal Army Service Corps in the First World War, rising to the rank of major, and returned to Doncaster after the Armistice. From 1923 he served as personal assistant to Nigel Gresley of the LNER, working closely on Gresley's express designs through the 1920s and 1930s. In 1937 he accepted the post of Chief Mechanical Engineer of the Southern Railway in succession to Richard Maunsell.

His tenure at the Southern produced a distinctive and controversial design portfolio. The Merchant Navy Pacific class of 1941 introduced welded boilers, thermic syphons and his signature chain-driven valve gear enclosed in an oil bath. The lighter West Country and Battle of Britain Pacifics followed from 1945. The wartime Q1 0-6-0 austerity freight class of 1942, with its unconventional shrouded boiler, was designed to maximise haulage from minimum materials. His most ambitious experiment, the Leader Class double-cab tank engine of 1949, never entered service.

After British Railways nationalisation Bulleid's chain-driven valve gear was found to be unreliable in service and many of his Pacifics were extensively rebuilt to a more conventional design between 1957 and 1961. In 1950 Bulleid was appointed CME of Coras Iompair Eireann, the nationalised Irish transport authority, where he developed prototype peat-burning locomotives, the most notable being the CC1 turf burner of 1957. He retired in 1958 and died in Malta on 25 April 1970.
