He was born in Clapham on 14 May 1800, the son of Isaac Railton and his wife, Margaret Maria Railton, née Scott. He was a pupil of the London architect and surveyor William Inwood. In 1825 Railton set off for a tour of Greece and Egypt. On his return to England he prepared for publication some drawings he had made of the remains of the recently excavated Kardaki Temple on Corfu. They were printed as a supplementary volume to James Stuart's Antiquities of Athens under the title of The newly-discovered Temple at Cadachio Illustrated. In the mid-1830s, Railton carried out several commissions for Ambrose March Phillipps, a Leicestershire landowner who had converted to Catholicism at an early age. On his marriage his father, Charles March-Phillipps of Garendon Park, had given him one of the family's other Leicestershire estates, on which stood the ruins of Grace Dieu Priory. There, Railton built the neo-Tudor Grace Dieu Manor, complete with chapel. Meanwhile, Ambrose Phillipps bought - with borrowed money - a tract of land in nearby Charnwood Forest to build a monastery for a community of Trappist monks, to be named Mount St Bernard. Railton designed a church and monastic buildings, once again employing a neo-Tudor style. The church was consecrated in October 1837. Railton's buildings were, however, soon replaced by a more ambitious monastic complex to plans by Augustus Pugin. For Charles March Phillipps, Railton designed lodges and gatehouses for Garendon Park, which have survived the demolition of the main house. Railton also designed two identical Anglican churches in Charnwood Forest, at Copt Oak and Woodhouse Eaves,. He built further churches nearby at Groby and Thorpe Acre, the latter on land donated by Charles March Phillipps. Also in Leicestershire, he designed Beaumanor Hall for the Herrick family. At Ripon he designed a palace for the bishop. The foundation stone was laid at a ceremony in October 1838, and by the end of 1841 it was ready for the bishop to move in. Four years later, Railton was asked to add a chapel, slightly separate from the palace, to allow the local population to worship there. In deference to the Tudor style of the palace, he chose the perpendicular style, battlemented like the main building. Between 1838 and 1848 he was employed as architect to the Ecclesiastical Commissioners for whom he produced two standard designs for parsonages. During this time he also remodelled Riseholme as a house for the Bishop of Lincoln. In 1836 he won the fourth prize in the competition to design a replacement for the Houses of Parliament which had recently been destroyed by fire, and in 1839 came first in the competition to design a monument to Admiral Lord Nelson in Trafalgar Square, London. His winning design – a simple Corinthian column topped with a statue of Nelson – was constructed between 1839 and 1842; the lions on the base, although part of the original plan, were not added until 1867. Railton exhibited at the Royal Academy between 1829 and 1851. He built nothing after 1850. He lived at 65 Onslow Square, Kensington, in the later part of his life, and died on 13 October 1877, while visiting Brighton.
