London Transport's Silver Jubilee AEC Routemaster buses are launched.

The Silver Jubilee of Elizabeth II marked the 25th anniversary of Queen Elizabeth II's accession to the thrones of the United Kingdom and other Commonwealth realms. It was celebrated with large-scale parties and parades throughout the United Kingdom and the Commonwealth throughout 1977, culminating in June with the official "Jubilee Days", held to coincide with the Queen's Official Birthday. The anniversary date itself was commemorated in church services across the land on 6 February 1977, and continued to be for the rest of that month. In March, preparations started for large parties in every major city of the United Kingdom, as well as for smaller ones for countless individual streets throughout the country.

The London Transport Executive was the executive agency within the Greater London Council, responsible for public transport in Greater London from 1970 to 1984. In common with all London transport authorities from 1933 to 2000, the public name and operational brand of the organisation was London Transport.
