First did the Ft.Wm.to Mallaig road by car back in the '70s, when it was even narrower than it is now. Herring were still coming ashore in Mallaig in large quantities, and being smoked there too. Along that road is Arisaig (where parts of Local Hero were filmed) and Morar (birthplace of . . . . . Carol (BBC Weather) Kirkwood!) with its silver sand beaches. Did that route a few more times by train, and just once behind steam - wonderful, wonderful.
One of my favourite drives, after leaving Stirling and The Trossachs, is from Crianlarich and up and across Rannoch Moor, on the way to the descent through Glencoe. One day, we dumped the car at Crianlarich, and got on the train to go to Fort William. Bought tickets, boarded train, departed - and a few minutes later, the train stopped at Tyndrum Lower station. Lower! Oh b*gger! Wrong train (this one was heading to Oban)! No problem; we got out, taking the guard's tannoyed advice "Alight here for Tyndrum Upper and Fort William".
One snag - well, two, actually: it had started to rain, hard. Undaunted, we set off. There was even a signpost. Now, Tyndrum is a pretty small village, but it has two stations, on two lines, each half way up a hillside, and (as we discovered) best part of 2km apart, as the walker goes. Soggy, and out of breath, we approached Tyndrum Upper station (which is very much upper), and arrived there in steaming heaps, just as the train arrived. The guard checked our tickets, looked at us knowingly, and said something about Tyndrum Lower and what a nice walk it is. He then produced two cups of tea, with his compliments. Magic.
