I wonder if anyone can clarify the dates of when the various GNE eras started

- When were the local brands introduced - Wear Buses, Coastline, Go Ahead Gateshead etc?

- When did they all get rebranded into the red/blue corporate livery as Go Gateshead, Go Northern etc. Was there ever a Go VFM Buses, or had that been discontinued by then?

- When did those names get phased out and combined as Go North East?

- When did the route branding era start?
