I'd say as a starting point if Arriva get a big investment in the near future, this is what they should do as a starting point:
- 17x ADL E400MMC (ZF) for X21 / X22 (incl 2x spare)
* 7541-50 go to Blyth for 308 with 7551/52 as spares for 308/X10/X11
- 14x ADL E400MMC (ZF) for X10 / X11 (incl 1x spare)
- 6x Scania E400MMC (ZF) for X18
- 5x Scania E400MMC (ZF) for X15
- 6x Scania E400MMC (ZF) for X93
