  Transport is one of the four main areas of policy administered by the Mayor of London, but the mayor's financial control does not extend to the longer-distance rail network that enters London. In 2007, the Mayor of London assumed responsibility for some local lines, which now form the London Overground network, adding to the existing responsibility for the London Underground, trams and buses. The public transport network is administered by Transport for London (TfL).
  
  The lines that formed the London Underground, as well as trams and buses, became part of an integrated transport system in 1933 when the London Passenger Transport Board or London Transport was created. Transport for London is now the statutory corporation responsible for most aspects of the transport system in Greater London, and is run by a board and a commissioner appointed by the Mayor of London.
