West Highland Line

The route at a glance

The West Highland Line leaves Glasgow Queen Street, follows the Clyde towards Helensburgh, then runs beside Gare Loch, Loch Long and the upper end of Loch Lomond. At Crianlarich, services divide: one branch continues west through Glen Lochy and along Loch Awe to Oban; the other heads north through Bridge of Orchy, Rannoch Moor and Fort William before reaching Mallaig.

The full Glasgow–Mallaig trip takes about 5 hours 30 minutes. Glasgow–Oban takes about 3 hours 20 minutes, while Glasgow–Fort William takes about 3 hours 50 minutes. Treat it as a journey rather than a quick transfer: the appeal is the changing terrain outside the window.

What to watch for

• Loch Lomond and Loch Long: the southern section trades Glasgow's suburbs for steep-sided water and forest.
• Rannoch Moor: north of Bridge of Orchy, the Mallaig branch crosses open peatland with lochans and distant mountains. Much of this country has no road access.
• Corrour: on the moor, this is the UK's highest mainline station and has no public-road access.
• Glenfinnan Viaduct: beyond Fort William, the line curves across the 21-arch concrete viaduct above Loch Shiel.
• The coast to Mallaig: Loch Eilt, Loch Ailort, Morar's sands and views towards Skye finish the northern branch.

The Oban branch has its own strong run of scenery: Loch Awe, Ben Cruachan and the Pass of Brander lead to the harbour town.

Riding it well

Start at Glasgow Queen Street, not Glasgow Central. Check the destination on the departure board before boarding: trains may divide at Crianlarich, with portions continuing to different terminals. If travelling to Fort William or Mallaig, make certain you are in the correct part of the train before the split.

Regular ScotRail services run year-round. Advance fares are tied to a specific service; flexible tickets suit travellers who want room to stop or adjust plans. Seat reservations are not compulsory, but are useful on busy summer services. Bring food and water for the longer runs, particularly if you are travelling through the remote Mallaig branch.

Stops and onward travel

Fort William is the practical break point for an overnight between the moor and coast. Glenfinnan is the station for the viaduct and monument. Mallaig is the rail terminus and a ferry port for Armadale on Skye and the Small Isles. At the other end of the split, Oban connects directly with island ferries.

The seasonal Jacobite steam service uses the Fort William–Mallaig section, but it is separate from the regular rail service. The standard ScotRail train crosses the same viaduct and reaches the same coastal stations.
