In 1979 the organisational structure of the BRB's railway operations still largely reflected that of the Big Four British railway companies, which had been merged to create British Railways over 30 years previously. There were five Regions (Scotland being a separate region), each region being formed of several Divisions, and each division of several Areas. There was some duplication of resources in this structure, and in the early 1980s, the divisional layer of management was abolished with its work being redistributed either upwards to the regions or downwards to the areas.
