Billy Mill to MetroCentre
limited stop via Coast Road, Newcastle Haymarket and Teams
every 20 minutes
This service will provide connections to the MetroCentre from the Newcastle and SE Northumberland areas, without having to change onto another operators' service.
A service like that would make a lot of sense.
I think Arriva do lose out a fair bit by not having a very big presence in Gateshead (only really the X12 and the barely worth having X24, these days. They had more a decade or so ago, when some services were shared) or Sunderland (just the Peterlee services from the South - all of which have strong competition from GNE)
