One of Britain's great railway journeys closes for nine days next month
What happened
On 6 October 2026, Network Rail Scotland gave a month's notice of a major closure on the West Highland Line. Buses will replace trains between Crianlarich and Fort William, and between Crianlarich and Mallaig, from Monday 9 November to Tuesday 17 November 2026. That is nine days. The work covers several different jobs at once. More than four kilometres of track is being renewed at various points along the line, including at Arisaig, at Corrour, and in the tunnels at Loch nan Uamh and Beasdale. Drainage is being improved and a culvert replaced between Glen Douglas and Arrochar & Tarbet. A culvert is the channel that carries water underneath the railway. Where these block or fail, the result is a washout or a landslip, which is the main cause of unplanned closures on this line. Fassfern Bridge, near Spean Bridge, is being refurbished, and a redundant structure near Loch Eil is being removed. Vegetation is being cleared between Fort William and Arisaig. Gerry McQuade of Network Rail Scotland said the closure "gives us the opportunity to carry out a large amount of work in one go". Mark Ilderton of ScotRail said the work would "help make the railway more reliable and resilient".
Why this matters
The West Highland Line is two things at once, and both are affected. It is a tourist route, regularly described as one of the most beautiful railway journeys in the world. It runs from Glasgow up past Loch Lomond, across Rannoch Moor, to Fort William, and then on to Mallaig over the Glenfinnan Viaduct. People book it from the other side of the world. It is also a lifeline. For communities along the line, including Arisaig, Morar and Mallaig, it is how people get to appointments, to shops, to school and to the ferry for the islands. There is a road, but it is a long one, and in winter it is not always open. So a nine-day closure matters in two different ways. Visitors need to know before they book. Residents need to know how the replacement buses will work. November is a deliberate choice. It is after the main tourist season and before the Christmas period, and the days are short enough that the line is quieter. That is the least bad window. The drainage and culvert work is the part most worth caring about. The West Highland Line's biggest reliability problem is water: heavy rain, landslips and washouts. Fixing drainage is the unglamorous work that keeps the line open in February.
What the evidence actually says
A few honest points. The announcement does not include a cost figure. Network Rail has not published one for this package of work, so anyone quoting a number for it is guessing. Engineering dates can move. A month's notice is good practice, but weather in the Highlands in November is a real factor, and the exact pattern of bus replacement can be adjusted. Re-check close to the date. The quotes about reliability and resilience are from Network Rail and ScotRail, which is to be expected. The reasoning behind them is sound: track renewals, drainage and bridge refurbishment do reduce faults. But a nine-day blockade does not make a rural single-track line through mountains immune to storms. It reduces the risk; it does not remove it. It is also worth noting what is not in this closure. The section between Glasgow and Crianlarich, and the Oban branch, are not listed as having buses replace trains, though timetables either side of a blockade are often affected anyway. Check the specific journey you want rather than assuming. And replacement buses on this route are a significantly different experience from the train. The roads are winding, the journey takes longer, and the views from a bus on the A82 are not the views from Rannoch Moor.
Practical advice
If you have booked, or are about to book, a trip on the West Highland Line: Avoid 9 to 17 November 2026 if the train journey itself is the point of the trip. The scenery is the product, and a bus does not deliver it. If you must travel in that window, check ScotRail's website for the replacement bus timetable and allow considerably more time than the train would take. If you have a ferry to catch from Mallaig or Oban, build in a large margin. A missed connection to an island ferry can mean a missed day. If you use a wheelchair or a mobility scooter, or need help to travel, book ScotRail's Assisted Travel service in advance. Replacement buses cannot always take every mobility aid, and booking ahead means a suitable vehicle is arranged. It is free, and on a route like this it is essential rather than optional. If you live along the line and have a hospital appointment in that window, ring the department early. Many will move an appointment when transport is the obstacle, and there may be patient transport you are eligible for. And whatever time of year you travel in the Highlands: carry your regular medicines in your hand luggage or day bag, not in a case in the hold or the boot, with enough for a few extra days. Weather disruption here is normal, not exceptional, and a day stuck somewhere should not mean a day without your tablets.
What to know
Buses will replace trains on the West Highland Line between Crianlarich and Fort William, and between Crianlarich and Mallaig, from Monday 9 November to Tuesday 17 November 2026. The announcement was made on 6 October. The work includes more than four kilometres of track renewal at Arisaig, Corrour and the Loch nan Uamh and Beasdale tunnels, drainage improvements and a culvert replacement between Glen Douglas and Arrochar & Tarbet, refurbishment of Fassfern Bridge near Spean Bridge, removal of a redundant structure near Loch Eil, and vegetation clearance between Fort William and Arisaig. The drainage work is the most valuable part for anyone who depends on the line in winter, because water is the main cause of unplanned closures. If the scenic journey is the reason for your trip, travel outside those dates. If you need assistance, book ScotRail's Assisted Travel service in advance. And carry your medicines with you rather than in the hold.
