Network Rail embarks on a significant £3.5M restoration of the historical Awe viaduct, set to enhance its structural integrity and lifespan.
- The timber deck replacement is scheduled for October 2024, requiring a temporary track closure over two weekends.
- Story, as principal contractor, is tasked with the refurbishment, alongside its scope of work in the £1.3bn Scottish rail improvement commitment.
- The project involves meticulous care in protecting the viaduct’s metallic components, with a three-layer paint system against corrosion from natural elements.
- Residents are being notified to ensure community awareness and understanding as the substantial refurbishment takes place.
The restoration of the 1879-built three-span wrought iron Awe Viaduct is a focal point of Network Rail’s commitment to maintaining and enhancing the nation’s railway infrastructure. Set to commence in October 2024, the project will replace the ageing timber deck over two non-consecutive weekends, necessitating the temporary removal of track to facilitate the installation of new materials. Such undertakings are indispensable to prolong the functional life of this vital structure, which carries the Crianlarich-Oban line over the River Awe in picturesque Argyll and Bute.
Network Rail has engaged the expertise of Story, a principal contractor already earmarked for delivering a host of improvements under a larger £1.3bn initiative for Scotland’s railway network over the ensuing five years. Within this framework, Story, in collaboration with AmcoGiffen, will undertake up to £730M worth of enhancements on various structures including tunnels, underbridges, and coastal defences. As part of its broader remit, Story will also implement a scour protection programme on the Fillan Viaduct, located on the West Highland Line.
The restoration procedure is extensive, requiring the scaffolded and encapsulated preparation of the site to allow for the safe and effective replacement of the timber deck. Engineers will strip away aged paint using a blasting technique and apply a robust three-layer paint system to shield the metal components from rust, significantly reducing the need for future maintenance. This three-layer approach is designed to withstand the region’s climatic challenges, ensuring the viaduct remains a sturdy component of the railway network for decades to come.
Meetings with local residents have been pivotal in ensuring the community remains informed and supportive of the project’s aims. Network Rail project manager Owen Ferry articulates the significance of these efforts, noting: “This significant investment not only improves the structure’s look but will help extend its lifespan as work on this scale won’t be required for at least another 25 years.” Residents have been assured of continued communication as the project unfolds, fostering transparency and cooperation.
This ambitious refurbishment underscores Network Rail’s dedication to safe and sustainable railway operations.
