RE: Concerts in Tyne and Wear - Special SF Buses and Metro
It seems Arriva ran a few extra buses out of Haymarket. 306 at one point was a mix of Walkergate/Blyth/Ashington buses. Seen a few extra X7/8(even though that doesn't run)X9/10/11/21/22/308/52/43/44 be about one or two more of these services
