Work is about to get underway on a final phase of embankment and drainage work at Slochd between Perth and Inverness on the Highland Mainline.
The project, which will be ongoing until November will help protect against landslips and rockfall and also address a known flooding risk area which has caused delay and cancellation to passenger journeys twice in the last twelve months.
It represents an investment of £4.8 million to protect the infrastructure.
Work will see installation of a new piped drainage system and earth-bunds, as well as concrete lined ditches to manage the flow of water away from the railway to culverts and natural water courses.
The project, which is being delivered over two kilometres of railway has been on site at Slochd since September 2019 and has targeted known areas of embankment with a history of instability and prone to rock-fall and flooding.
