The West Highland Line ( – "Iron Road to the Isles") is a railway line linking the ports of Mallaig and Oban in the Scottish Highlands to Glasgow in Central Scotland. The line was voted the top rail journey in the world by readers of independent travel magazine Wanderlust in 2009, ahead of the notable Trans-Siberian line in Russia and the Cuzco to Machu Picchu line in Peru. The ScotRail website has since reported that the line has been voted the most scenic railway line in the world for the second year running.
The West Highland Line is one of two railway lines that access the remote and mountainous west coast of Scotland, the other being the Kyle of Lochalsh Line which connects Inverness with Kyle of Lochalsh. The line is the westernmost railway line in Great Britain.
At least in part, the West Highland Line is the same railway line as that referred to as the West Highland Railway.
History The route was built in several sections: Glasgow Queen Street to Cowlairs Junction - Edinburgh and Glasgow Railway Cowlairs Junction to Bowling - Glasgow, Dumbarton and Helensburgh Railway (later absorbed into the Edinburgh and Glasgow Railway) Bowling to Dumbarton Central - Lanarkshire and Dumbartonshire Railway, operated by the Caledonian Railway Dumbarton Central to Dalreoch - Caledonian and Dumbartonshire Junction Railway Dalreoch to Craigendoran - Glasgow, Dumbarton and Helensburgh Railway Craigendoran to Fort William (opened 11 August 1894) - West Highland Railway sponsored by the North British Railway Crianlarich to Oban - Callander and Oban Railway, operated by the Caledonian Railway.
There is an additional section from Fort William (or a junction near Fort William) to Mallaig, built as the Mallaig Extension Railway. The West Highland Railway approved the construction of the line at their annual meeting in January 1895.
The line faced potential closure as part of the Beeching cuts in 1963 and again in 1995 due to reduced revenues.
Route description Shortly after leaving Glasgow Queen Street station, and beyond Queen Street Tunnel, the line diverges from the main trunk route to and at and follows a northwesterly course through the suburbs of Maryhill and Kelvindale. Between and Dumbarton, the route is shared with the North Clyde Line to before branching northward at Craigendoran Junction towards , the section where the West Highland Line itself is generally accepted to begin. It gives high-level views of the Gare Loch and Loch Long before emerging alongside the northwesterly shores of Loch Lomond, then climbs Glen Falloch to .
The branch to Oban diverges at Crianlarich, an important Highland junction of both road and rail, and runs through Glen Lochy to and through the Pass of Brander to reach salt water at and before a final climb over a hill to . About from Crianlarich, the Mallaig and Oban routes both pass through the village of Tyndrum, but they are served by separate stations, making it an unusually small settlement to be served by more than one railway station.
After , the line to Mallaig climbs onto Rannoch Moor, past the former crossing point at Gorton Crossing to station. In winter, the moor is often covered with snow, and deer may be seen running from the approaching train. The station at on the moor is one of the most remote stations in Britain and is not accessible by any public road. This is the summit of the line at 1347 ft (410 m) above sea level. Carrying on northwards, the line descends above the shores of Loch Treig and through the narrow Monessie Gorge. The final stop before Fort William is . The section between Fort William and Mallaig passes over the Glenfinnan Viaduct, through Arisaig with its views of the Small Isles of Rùm, Eigg, Muck and Canna, and the white sands of Morar before coming to Mallaig itself.
With the exception of the route between Glasgow Queen Street and Helensburgh Upper, and the short section between Fort William Junction and Fort William station, the railway is signalled using the Radio Electronic Token Block, controlled from the signal box at Banavie station.
Services Passenger services on the line are operated by ScotRail and Caledonian Sleeper. As of December 2025, the service pattern is as follows:
3tpd each way Mallaig - 1tpd each way Mallaig - 1tpd Oban - Dalmally 6tpd each way Oban - Glasgow Queen Street. Additionally, 1tpd Glasgow Queen Street - Oban (one way only)
All of the services from Glasgow Queen Street - Mallaig are combined with services to Oban, splitting at Crianlarich. Similarly, two of the return services combine at Crianlarich.
During the summer season from May until October a steam locomotive-hauled daily return service between Fort William and Mallaig known as The Jacobite is operated by West Coast Railways. There is one train a day in May, September and October, and two trains per day from June until the end of August.
Caledonian Sleeper operates a nightly service (except Saturday) from Fort William to London Euston, with northbound services also 6 nights per week.
Onward ferry connections operated by Caledonian MacBrayne are available from Mallaig to the Isle of Skye, to the small isles of Rùm, Eigg, Muck, and Canna, to South Uist, and to Inverie on the Knoydart peninsula. From Oban ferries sail to the islands of Lismore, Colonsay, Coll, Tiree, Mull and Barra.
As of 2021, there is a single regular freight operation on the line, consisting of alumina services from North Blyth to a smelter near Fort William.
Route timings Since improvements to Scottish trunk roads in the 1980s, a train journey can take significantly longer than the equivalent road journey. There are several reasons for this. The line is entirely single track once it leaves the North Clyde suburban network at and trains must wait at stations with crossing loops for opposite direction trains to pass. Even when no crossing is timetabled, each train must pause at various token exchange points whilst the driver contacts the main signalling centre at to swap tokens electronically and obtain permission to proceed. Up to 15 minutes have to be allocated for trains to divide or combine at the junction station at , whilst trains heading to/from Mallaig also have to reverse at Fort William & traverse the Banavie swing bridge at low speed. A further issue is finding suitable timetable paths for Oban & Mallaig trains on the busy North Clyde line, which carries an intensive local stopping service. As West Highland trains only stop at Dumbarton Central and Dalmuir on this stretch, it is not uncommon for them be delayed by a preceding local train and so recovery time has to be included in their schedules to reduce the possibility of a late arrival in Glasgow.
Over much of the Rannoch Moor section the speed limit is for the Sprinter and on the approach to Rannoch station. The Caledonian Sleeper travels at maximum, slowing down for a number of bridges on the route due to the heavy weight of the locomotive which hauled the train until the end of the old franchise in April 2015. The operator of the sleeper Serco has replaced these with refurbished electro-diesels since it took over, which have a lighter axle load; it is not yet clear whether the new locomotives will be cleared to run at higher speeds now they are in service.
