Little is known of Craven's parentage and there is also some confusion over his early career, but all sources agree that he was born 11 September 1813 at
Hunslet a suburb of
Leeds. According to John Marshall, Craven began an apprenticeship with
Robert Stephenson and Company of
Newcastle, later transferring to
Fenton, Murray and Jackson of Leeds at the age of fourteen. Bradley states that he began his apprenticeship Fenton Murray and Jackson. He appears to have left Fenton, Murray and Jackson in 1837, and worked briefly for
Carrett, Marshall and Company of the Sun Foundry, followed by a year working for
Maudslay and Company of Westminster. He then returned to Leeds to become works manager either for
Todd, Kitson & Laird followed by
Shepherd and Todd or else
Shepherd and Todd. He spent three years at Leeds working with
David Joy and
John Gray, before he was appointed Locomotive Foreman of the
Manchester and Leeds Railway (M&LR) on 9 November 1842, under
James Fenton. Following the resignation of Fenton in January 1845, William Jenkins was appointed to replace him in February, and Craven was promoted to outdoor locomotive superintendent under Jenkins. Craven resigned from the M&LR in May 1845 and then became Locomotive Engineer for the
Eastern Counties Railway at
Stratford Works but little is known of his work there. In December 1847 he took up his principal post as Locomotive, Carriage and Wagon Superintendent of the
London, Brighton and South Coast Railway following the dismissal of John Gray. ==Brighton==
