Major Upgrade Works Set for Dunblane–Bridge of Allan Rail Line
More than £4 million will be channelled into upgrading the railway between Dunblane and Bridge of Allan early next year, as Network Rail prepares a series of structural improvements aimed at strengthening the line for decades ahead.
The programme focuses on three key structures along the route, each due for targeted engineering work designed to tackle ageing infrastructure, enhance safety and improve overall resilience. Network Rail says the investment underlines its commitment to keeping the line reliable for passengers and freight operators alike.
At Kippenross Tunnel, teams will move in from 5 January to reinforce weakened brickwork using sprayed concrete. They will also carry out essential masonry repairs, improve drainage inside the tunnel and refresh signage, forming part of a wider effort to address long-standing water and structural issues.
Work on the Bridge of Allan footbridge is scheduled to begin on 19 January, with the structure temporarily closing from 27 February until 26 April. Crews will replace the timber deck, strengthen steel and masonry elements, extend parapet walls and apply protective paint. Vegetation will be cleared from around the bridge to maintain safe public access and prolong the bridge’s lifespan.
The Mill of Keir Viaduct will undergo a separate phase of repairs starting on 23 February. Engineers will install additional steel supports to reinforce parapets and spandrel walls, while masonry repairs, new signage and drainage clearance form part of the wider upgrade package to secure its long-term stability.
Rail services between Dunblane and Bridge of Allan will be altered over two weekends—28 February to 2 March, and 14 to 16 March—while work takes place. Network Rail says the temporary changes are necessary to ensure staff can complete the improvements safely.
Stephen Orr, scheme project manager at Network Rail, said:
“The work is vital to maintaining safe and reliable infrastructure for everyone who uses these routes. By reinforcing structures, improving drainage, and upgrading signage, we’re ensuring these assets remain fit for the future. We’re also focused on sustainability, extending the life of existing structures and reducing the need for more disruptive interventions later. We appreciate the patience of the local community while these essential improvements are carried out, as they will deliver long-term benefits for generations to come."
Mark Ilderton, ScotRail service delivery director, said:
“When this essential improvement work takes place, our priority will be to keep customers moving and provide clear information so they can plan their journeys with confidence. We’ll be working closely with Network Rail to support the safe delivery of these upgrades, which play an important role in maintaining a reliable railway and ensuring the long-term sustainability of the route. Where journeys are impacted, we’ll make sure customers know what their options are, including any rail replacement transport. We appreciate the patience and understanding of everyone travelling during the works, and we encourage our customers to check their journey before they travel.”
All three projects are expected to conclude by late May.
