It operates passenger services, mostly out of London Waterloo station, to the South West of London and in the counties of Surrey, Hampshire, Dorset, Devon, Somerset, Berkshire, and Wiltshire and on the Isle of Wight. The area of operation, essentially the former South Western division of Network SouthEast, is also roughly that of the pre-1923 London and South Western Railway (excluding everything west of Exeter). The Stagecoach Group took over the franchise on the privatisation of British Rail in 1996 and retained it in 2004 and again in 2007 making it, along with First Great Western, the longest-running franchise. It is the largest passenger franchise in the UK and is a particularly complex operation due to the large number and variety of services.
