I was aware of the service.
Before it eventually became a coach-based service operated by Go North East, it was operated by OK Travel largely as a Saturday (it might have ran a couple of other days too - I can't remember) shoppers service to the Metrocentre alongside service X27 which operated between Fishburn/Hutton Henry and the Metrocentre.
Considering neither incarnation of the service exists, I think it is safe to say it wasn't particularly well used.
