The Greater Anglia franchise was formed by the merger of the InterCity Great Eastern, Great Eastern and the West Anglia half of the West Anglia Great Northern franchises. It was renamed as East Anglia in 2016.
In 2004, National Express won the right to operate the then new Greater Anglia franchise. It was branded 'One' which was an acronym for "Operated by National Express".
