London Transport Board , 1963-1970

In 1929 the London County Council tramways, the Underground railways and the London General Omnibus Company proposed to coordinate their services. It was not until 1933, however, that the London Passenger Transport Board (LPTB) was established by law. During the Second World War the government assumed control of the LPTB, and remained in charge until 1947. The LPTB became the London Transport Executive in 1948.

In 1963, under the 1962 Transport Act, the London Transport Executive became the London Transport Board, reporting to the Minister of Transport. The company continued to use the name "London Transport" in public, as it had done since 1933. The London Transport Board had responsibility for the London Underground and bus services in London, which was roughly defined as the area controlled by the Greater London Council (GLC). In 1970 responsibility for transport was transferred to the Greater London Council.
