I do think that if it does get sold off bit by bit, Ashington depot would fit perfectly within GNE's current strategy. Only trouble would be service number parity for existing and incoming services so this is what I'd suggest:

Current GNE services:
- X15 > X4
- X20 > 20X or X90
- X30 > X2
- X31 > X3
- X32 > X3A

Incoming Arriva services:
- X15 = Same
- X20 = Same
- X21/ X22 > X31/X32 (Paying homage to previous incarnations)
- 35 > 435
