krus_aragon -- thanks for the map in post #6 above, showing Nova Scotia's railways presumably at their maximum extent -- quite fascinating. English-speaking Canada certainly has some marvellous place-names (as does Quebec in its different way).
Something of a trivial / personal thing; but I find it rather delightful to discover that Pugwash was at one time the terminus of a short branch from Pugwash Junction -- all lines concerned, long abandoned, I would guess. Two or three decades ago, my brother and his then wife spent a holiday with relatives of hers who lived in Nova Scotia. My brother has no interest in railways; but he had a great yen to visit Pugwash, because of a childhood passion for the TV-cartoon series about the (gentle and inept) pirate hero of that name. He insisted one day on taking a long drive, with wife and child, to Pugwash -- just to say he'd been to the place. He found it a very tiny settlement, almost totally without amenities of any kind; nonetheless returned from the expedition in triumph, delighted to have made it there.
