Oops, I agree@Whistler40145: I've just realised -- we've gone wrong, haven't we? Itinerary says Newcastle & Berwick / North British main line / Berwickshire Railway: which last, was the Reston -- St. Boswells branch. I'm the initial culprit -- you posted Reston, then I stayed on the main line and posted Grantshouse, and we went on from there. Taking stock -- do you agree?
At the risk of being a real pain -- shouldn't we be heading south from St. Boswells, toward Hawick and Carlisle??
