I can confirm that Greg in Weardale is correct: the PVR is 5. Buses have a 32-minute layover at Consett Bus Station, which is why the PVR is not 4. The vehicle allocation is three Dennis Tridents and two OmniCitys. Tridents are more-or-less guaranteed on the 0854 departure from Consett as this works off college service X78 and scholars 822, while the 1454 arrival at Consett works onto scholars 827. The other board which is allocated a Trident catches the morning peak customers and presumably requires a double-decked vehicle to alleviate capacity issues on a single decker.
The PVR of services X30/X31 is also 5 vehicles, and the vehicle allocation is four Dennis Tridents and one OmniCity.
As only three OmniCitys of Stanley's four form part of their vehicle allocation, the depot has one spare OmniCity which should see primary allocation to "Red Kite" services 45/46 in the event that a branded vehicle is unavailable.
Sorry to spoil the fun - but if the former "West Durham Swift" services were ever to receive an upgrade, there's a high likelihood it would be in the form of double decked vehicles all around. There are some runs which need a double decked vehicle due to interworking with scholars, and others should be allocated a double decked vehicle so that people can have a seat on their peak time commute.
