A railway line in the west Highlands has been closed to allow for £4.5m worth of upgrades to be carried out over the coming weeks.
The Kyle line stretches more than 50 miles (80km) from Inverness to Kyle of Lochalsh.
Around 4.5 miles (7km) of track will be upgraded between Achnashellach and Strathcarron, with worn rails, sleepers and ballast to be replaced in order to improve the long-term reliability and safety of the route.
To allow the work to be carried out safely, the line will remain closed between Dingwall and Kyle of Lochalsh until Monday 10 November.
The project also includes inspections of bridges and drainage improvements to help prevent flooding and weather-related disruption.
An amended train service has been put in place between Inverness and Dingwall, calling at Beauly, Muir of Ord, and Conon Bridge.
Buses will replace train services between Inverness and Stromeferry, with a shuttle bus connecting Stromeferry and Kyle of Lochalsh.
ScotRail Service Delivery Director Mark Ilderton said: “We’re grateful to customers for their patience and understanding when these vital improvements take place.”
