Network Rail engineers have started £3.6 million worth of repairs at the historic Avon Viaduct near Linlithgow.
The project, which is due to be completed by May 2027, will protect the future of the 23-span listed structure and the railway it carries across the River Avon between West Lothian and Falkirk.
The viaduct will undergo a range of improvements as part of the project, including masonry repairs, steelwork repainting and structural strengthening works.
Existing metal parapet handrails will also be replaced with glass reinforced polymer (GRP) parapets.
Network Rail said that, as a listed structure, the work has been carefully planned to respect the viaduct's heritage while addressing essential maintenance needs.

It has worked closely with local authorities and environmental specialists as plans for the project have progressed.
Ecological surveys have also been undertaken to identify and protect local wildlife, including nesting birds and bats, with appropriate mitigation measures being implemented where required.
Allison Flanagan, project manager at Network Rail Scotland, said: “This is an important investment in one of Scotland's historic railway structures. The work will help ensure Avon Viaduct continues to play its role on the railway while preserving its character for future generations.
“As well as extending the life of the structure, the project will help protect an important part of the local landscape and railway heritage for years to come.”
