In reply to a post by MrSaffron:

The reversal in base closure may have come too late for currently released plans...who knows it might be on future roll-out.

And Kinloss has (mostly) closed and Forres hasn't been upgraded, but Nairn has (further away) I'm wondering if actually there is something more complex in this rollout - such as where BTor has a larger exchange building and/or capacity to core networks.
