The London Transport Board was the organisation responsible for public transport (except main-line trains) in London, England, and its environs from 1963 to 1969.
It was an independent statutory undertaking reporting directly to the Minister of Transport, whose responsibilities were similar to those of the LTE, but with the addition of some railway lines previously the responsibility of British Railways.
[1][2] The LTB was responsible for the London Underground and for bus and coach services within the London Passenger Transport Area, an area with a radius of about 30 miles from Charing Cross established when the London Passenger Transport Board was formed in 1933.
By 1970 the roads in London had become so congested that the Greater London Development Plan included in its scope policy to reduce dependence on the car.
[3] Bus services outside the GLC area and Green Line Coaches were passed to a new company, London Country Bus Services, formed on 1 January 1970 as a subsidiary of the National Bus Company.
