This programme was filmed aboard a Class 158 Unit in February 1994 and shows the Highland Main line at its best! We take the high road on this magical journey starting at Perth station. The scenery speaks for itself as we progress through Dunkeld, Pitlochry, Aviemore and Carrbridge. We come across snow as we approach the summit of the route. The stations and infrastructure, including semaphore signalling, add a fascinating spectacle to this ex-Highland Railway line.
