West Highland Line 
One of the great travel journeys of the world. I got on at Dalmuir and off at Mallaig. The line between Glasgow and Mallaig was built in stages between 1889 and 1901. Oban was served by a separate line (called the Callander and Oban Railway) from Glasgow, which was opened in 1880. After most of the Callander and Oban Railway were closed in 1965, the Oban services were diverted via the West Highland Railway to enable them to reach Oban via Crianlarich.

The line passes Loch Long and Loch Lomond to Crianlarich, where most trains divide. One portion of the train heads west to the port of Oban, whilst the other portion travels up the rest of the original West Highland Railway. The route continues across Rannoch Moor to Fort William, where the trains reverse and head west in order to reach the port of Mallaig.

Sit on the right-hand side of the train for the best views overlooking Loch Lomond.

After Bridge of Orchy, the line climbs onto Rannoch Moor, past the former crossing point at Gorton Crossing to Rannoch station. In winter, the moor is often covered with snow, and deer may be seen running from the approaching train. The station at Corrour on the moor is one of the most remote stations in Britain and is not accessible by any public road.
