Back in 2004 when National Express won the Greater Anglia franchise, they operated it under One but kept the former franchise names from Anglia Railways, First Great Eastern and WAGN as sub-brands with the exception of Stansted Express which was left as it's own sub brand with the sub-brands being used were: One Anglia, One Great Eastern and One West Anglia. This they did for the first two years of the franchise.

This helped to differentiate between all four brands and helped foster pride for services operated by each one.

This timetable was set during the December 2005 to May 2006 timetable period.
