X2 renumbered X12 - given the recent clarification of the regulations around split services, it's not surprising to see this one happening.
If this is the case with the X12/X2 it's a pity they couldn't have just made the whole route have the X2 as it's service number, although they wouldn't do this now after just renumbering the X1 as the X12.
