William Adams (15 October 1823 – 7 August 1904) was an English railway engineer. He was the Locomotive Superintendent of the North London Railway from 1858 to 1873; the Great Eastern Railway from 1873 until 1878 and the London and South Western Railway from then until his retirement in 1895. He is best known for his locomotives featuring the Adams bogie, a device with lateral centring springs (initially made of rubber) to improve high-speed stability. He should not be mistaken for William Bridges Adams (1797–1872) a locomotive engineer who, confusingly, invented the Adams axle – a radial axle that William Adams incorporated in designs for the London and South Western Railway. History Adams was born on 15 October 1823 in Mill Place, Limehouse, London, where his father was resident engineer of the nearby East and West India Docks Company. After private schooling in Margate, Kent he was apprenticed to his father's works. The railway surveyor Charles Vignoles had previously worked on the construction of the London dock basins and this association then secured a position for Adams as an assistant in his drawing office. The final years of apprenticeship were spent at the Orchard Wharf works of Miller & Ravenhill, builders of engines for steamships. In 1848 Adams became assistant works manager for Philip Taylor, an ironfounder, millwright and former assistant to Marc Brunel, who had set up workshops in Marseilles and Genoa to build and install marine engines. Fluent in French and Italian, Adams soon found himself effectively the superintendent engineer for the Royal Sardinian Navy, although still nominally working for Taylor. (The Kingdom of Sardinia then encompassed Genoa and much of what is now north-west Italy.) In 1852 he married Isabella Park, the daughter of another English millwright working in Genoa, and returned to England. On his return to England Adams initially worked as a surveyor: considering possible routes for a railway on the Isle of Wight, overseeing construction work at Cardiff Docks and planning and equipping new workshops at Bow for the East & West India Docks & Birmingham Junction Railway, soon to change its name to the North London Railway. This led to his appointment as the company's locomotive engineer in 1854, a post he held for eighteen years. Here he introduced his noted series of 4-4-0 tank engines, the first to use the laterally-sprung bogie, and the first continuous train brake. In 1873 Adams took
