Well if the deckers are all for Ashington routes, it would work out as:
- 3x - X21/ X22 (to replace classic E400s)
- 3x X14
- 4x X15
- 5x X18
- 4x X20

That's the full 19x allocated. Then the cascades available (18x) would be:
- 7514-17
- 7524-28
- 7529-34
- 7553-56

So they could do:
- 7514-7517 - 35 (PVR shortfall perhaps made up from perhaps 7510)
- 7522, 7524-25 - 43/44/45
- 7526-28 - Ashington spare
- 7529-34 & 7553-56 - 43/44/45

Then there'd be 11x full height E400 from 7501-09 & 7511-12 to replace older Geminis and take a more backseat spare role at Jesmond & Ashington.

I believe that all the Classic E400s have been converted to Euro 6?
