 Upon sectorisation, the London & South Eastern sector took over responsibility for passenger services in the south-east of England, working with the existing BR business units of Regions and Functions to deliver the overall service.Day-to-day operation, staffing and timetabling continued to be delivered by the Regions – and the sector came into existence with barely thirty staff based at Waterloo.On 10 June 1986, L&SE was relaunched as Network SouthEast, along with a new red, white and blue livery.
