The Arriva 21/21A new route in Peterlee is the following: between wingate and Peterlee A19 roundabout it follows GNE X7 route then between A19 and Peterlee bus station it does the old 24 route, the X21 goes between Peterlee bus station and A19 it does the X7 route then comes off A19 to go into ryhopeAh okay thanks.
I kept seeing notes about the route through Peterlee but I don't know Peterlee that well so was waiting for a map or to be told its instead of what route.
Bit disappointed that the timetable on the Arriva website doesn't give connection times between the 21/X21.
