Eastern Counties

The Eastern Counties Omnibus Company came about by the amalgamation of four companies the Peterborough Electric Traction Company, Ortona Motor Company Limited, the eastern operating area of United Automobile Services and the Eastern Counties Road Car Company of Ipswich. Registered on 14 July 1931, Eastern Counties was part of the Tilling Group until the Transport Act of 1968, which announced the formation of the National Bus Company. This was to take effect from 1 January 1969.

In 1984, in preparation for deregulation, Eastern Counties was split in to two separate companies, with Cambus being formed to take over operations in the Cambridge and Peterborough areas while, at the same time, the coaching operations were transferred to Ambassador Travel.
