James Holden (26 July 1837 – 29 May 1925) was an English locomotive engineer.
He is remembered mainly for the "Claud Hamilton" 4-4-0, his pioneering work with oil fuel, and his unique "Decapod".
James Holden was born in Whitstable, Kent on 26 July 1837. He was apprenticed to his uncle, Edward Fletcher and, in 1865, joined the Great Western Railway, where he eventually became chief assistant to William Dean. In 1885 he was appointed Locomotive Superintendent of the Great Eastern Railway, which placed him in control of Stratford works. He held office from 1885 to 1907 and was succeeded by his son Stephen (1908–1912), who enlarged the "Claud Hamilton" type into the capable Class S69 4-6-0 design.
James Holden was a Quaker. His style of management was rather paternalistic, and trade unionism was not encouraged. Holden had little regard for trade unions and believed employers should voluntarily look after their men. He was responsible for erecting the first hostel (1890) for enginemen arriving in London with late trains from the provinces.
Holden (who lived at Wanstead during his GER days) died in Bath, Somerset on 29 May 1925.
While to some extent his work consisted in improving the designs of his predecessors, Holden was responsible for several designs of his own. He completely reorganised Stratford Works, which, together with a considerable degree of standardisation, brought Stratford to an exceptionally high position among British locomotive works in the speed and efficiency of its locomotive production. Some of the extensively-built locomotive classes may not have been outstanding in performance on the road, or in fuel economy, but they were rugged in design and with their massive working parts were reliable and easy to maintain.
