Why would they go into X-lines? The PVR of the X5/X15 is four, and 6065 - 6068 are the four buses branded.
6065 - 6068 are undergoing preparation for service at Saltmeadows Road/Volvo. 6069 and 6070 are both in fleet livery, and are both at Volvo for MOT. Once tested they will be shared spares for the 16, 47 and X5/X15, alongside 6064 which is currently at East Yorkshire for further gearbox tweaks.
