The 3 Streetlites along with the 5 on the 23 at Durham - which have been rumoured to be being replaced previously - would provide 8 to cover the PVR of the 17/17A at Stockton depot, replacing the DAF Cadets which are due for disposal any time soon. 
Having said that I am unsure which service would provide a business case for 7 new DD's given the X18 has just received it's batch not that long ago. The only possible one would be the X21/X22 but that would obviously be a direct replacement for the 57 reg batch on there currently.
Bringing all of these thoughts together could it be there are 7 VLA's enroute to Ashington for the 35?
