If they had the vehicle resource from the X2 as an interworking pattern, they could probably up it to 10 minutes again, with two an hour continuing to Newcastle as a new X6 service. I'd say it would have to work to allow for X12 passengers to still connect on to it at Durham Bus Station though, with through-fares being available. 

For years it was 15 minutes between Durham and Bishop Auckland then at some point I think it ran to Cockfield every 30 minutes and Ramshaw as the 6A every 30 minutes combined every 15 minutes between Durham and Bishop Auckland. Then I think it became the 6 from Durham to West Auckland every 12 minutes with a revised 50/50A replacing the 6A to Ramshaw.

I think that's right but I may be wrong as Arriva have changed their services in Bishop Auckland quite a few times over the last 10 years so I forget but I don't believe the 6 was ever every 10 minutes.
