The line follows the coastal contours through Invergordon to Tain and heads inland via Lairg. After Rogart we pass through the long-since closed "Mound" station, still with it's platform for the Dornoch branch derelict but intact. We take a look at the remains of this erstwhile line and discover Dornoch station building still surviving. At Golspie the line became the "Duke of Sutherland's Railway" - one of the longest-ever privately built lines. Dunrobin Castle station is next on route. Here we learn a little about the Third Duke, from his great great grandson Lord Strathnaver. By the time the train reaches Helmsdale, the coast has become more rugged than ever. From there it proved absolutely impossible to drive the railway any furthe ralong the coast, so our "Sprinter" heads inland again, this time through the remote Strath of Kildonan for 25 miles to Forsinard. At least there is a road along the valley but from there to Georgemas the railway is quite alone. Filmed in 1991
