Network Rail is set to invest £15 million in a major programme of engineering works on the West Highland Line, one of the world’s most scenic railway routes.
The upgrade, beginning in October 2025, will improve the resilience, safety and reliability of the line, which connects remote Highland communities and popular tourist destinations such as Fort William, Mallaig, and the iconic Glenfinnan Viaduct.
The works are essential to maintaining the long-term performance of the railway, particularly in areas vulnerable to extreme weather and flooding.
The programme includes:
- Track renewals: 10km of rail and 9,100 sleepers replaced
- Bridge renewal near Corrour
- Vegetation management to improve visibility and safety
- Five culvert renewals to enhance drainage and structural stability
- Feith footbridge renewal
To deliver the upgrades safely, the line will be closed for nine days between Crianlarich and Fort William, from the evening of Friday 7 November to the morning of Monday 17 November 2025. Temporary compounds will be set up at Rannoch and Tulloch stations to support the work.
Network Rail Route Director Ross Moran said:
“This is a significant investment in the future of the West Highland Line, helping to ensure it remains safe, reliable and resilient for years to come. The route is vital for the communities it serves and for the many visitors who travel to experience one of the most scenic rail journeys in the world.
“We appreciate there’ll be disruption as a result of this work and thank passengers and communities in advance for their patience. These upgrades are essential to keeping services running smoothly in a remote and challenging environment."
The West Highland Line is a vital transport link for both local residents and visitors, playing a key role in supporting tourism and economic development in the Highlands. The investment will ensure the route remains safe, reliable and resilient for years to come.
Network Rail’s commitment to maintaining and improving rural infrastructure reflects its broader strategy to future-proof the railway against climate challenges and deliver better services for passengers.
