To be honest, I don't see anything majorly changing in Ashington. Blyth will be the worst hit if anything.

Most I can see at Ashington is X21/X22 reduced to every 30 mins each and maybe the X20 reduced from double to single deckers.

With a PVR reduction for the X21/X22/35 (from 21x to 14x), no doubt that would leave enough E400MMC to transfer from Ashington to Whitby / Redcar if needed to allow the B9TLs to take a back seat role.
