Before the of British Rail (BR) in 1982 the system was split into largely autonomous regional operations: those operating around London were the London Midland Region, Southern Region, Western Region and Eastern Region. Sectorisation of BR changed this setup by instead organising by the traffic type: commuter services in the south-east of England, long distance intercity services, local services in the UK regions, parcels and freight. The aim was to introduce greater budgetary efficiency and managerial accountability by building a more market-focused and responsive business, rather than privatising BR completely. It was expected that the London and South East sector would cover most of its operating costs from revenues, in contrast to heavily subsidised rural services.
