With an order of 19, it matches up all the 'X' routes match up at Ashington.

- 3x X21/X22 (extra MMCs)
- 5x X18
- 4x X15
- 4x X20
- 3x X14

Then there's 14x classic E400s available for cascades. With three kept as spares for Ashington, the other 11x will likely end up at Jesmond witth 7522.

Blyth's turn will be next and I reckon unless wanting to stick with ADL for commonality, probably a massive StreetDeck order potentially including the 306. If Arriva got rid of the X8 (replaced by an enhanced X7 and a new 42 or 43A service), Blyth's order would work out:

- 306/308 - 18x (all at Blyth or split with Walkergate / Jesmond)
- X9/X10/X11 - 13x
- X7 - 7x

Arriva could even throw some 6 Cylinder StreetDecks in for the X93 and allow 7401-06 to provide summer extras as well as providing extra support for Whitby, Redcar and Ashington depots depending on demand.
