The planning application on the Durham County Council website says that the depot will have 65 buses allocated.
The current allocation is 74, if you take out the Metrocentre Mini you've got 69, 68 if a spare went with it.
Can't see moving 3 Toonlink's out would be operationally sensible, maybe they might move the 30 to Riverside, which would probably get you to the planned 65 at Consett.
