'Go North East' refers to the depots held in the North Division of the company: Riverside, Percy Main and Hexham. 'Go Northern' refers to the depots held in the South Division of the company: Chester-le-Street, Deptford, Washington, Stanley, Peterlee and Crook.

Similarly, Stagecoach North East is divided into two legal companies (Busways and Transit), and Arriva's comparable example is of course Northumbria and Durham County.
