railways, beginning in the late 1830s. The availability of rapid transport enabled prosperous London workers to settle all across Surrey and travel daily to work in the capital. This phenomenon of commuting brought explosive growth to Surrey's population and wealth, and tied its economy and society inextricably to London. There was rapid expansion in existing towns like Guildford, Farnham, and most spectacularly Croydon, while new towns such as Woking and Redhill emerged beside the railway lines. The huge numbers of incomers to the county and the transformation of rural, farming communities into a "commuter belt" contributed to a decline in the traditional local culture, including the gradual demise of the distinctive Surrey dialect. This may have survived among the "Surrey Men" into the late 19th Century, but is now extinct. Meanwhile, London itself spread swiftly across north-eastern Surrey. In 1800 it extended only to Vauxhall; a century later the city's growth had reached as far as Putney and Streatham. This expansion was reflected in the creation of the County of London in 1889, detaching the areas subsumed by the city from Surrey. The expansion of London continued in the 20th century, engulfing Croydon, Kingston and many smaller settlements. This led to a further contraction of Surrey in 1965 with the creation of Greater London, under the London Government Act 1963; however, Staines and Sunbury-on-Thames, previously in Middlesex, were transferred to Surrey, extending the county across the Thames. Surrey's boundaries were altered again in 1974 when Gatwick Airport was transferred to West Sussex. In 1849 Brookwood Cemetery was established near Woking to serve the population of London, connected to the capital by its own railway service. It soon developed into the largest burial ground in the world. Woking was also the site of Britain's first crematorium, which opened in 1878, and its first mosque, founded in 1889. In 1881 Godalming became the first town in the world with a public electricity supply. The eastern part of Surrey was transferred from the Diocese of Winchester to that of Rochester in 1877. In 1905 this area was separated to form a new Diocese of Southwark. The rest of the county, together with part of eastern Hampshire, was separated from Winchester in 1927 to become the Diocese of Guildford, whose cathedral was consecrated in 1961. During the later 19th century Surrey became important in the development of architecture in Britain and the wider world.
