RE: Arriva North East: Upcoming Service Changes
more than likely that service 22 which runs from Sunderland Interchange to Peterlee at 37 minutes past each hour might turn into a service X22 from Sunderland to Peterlee along the X21 route which in turn provide almost a 30 minute frequency with the X21 and the X22 will leave Sunderland almost the same time as GNE X7 but the X22 will be quicker to Peterlee than X7.
