Residents in the north-east have been warned of overnight works as part of a major railway project.
Network Rail is currently in the middle of a £300 million scheme to dual the track between Aberdeen and Inverness in a bid to improve journey times.
Letters have been sent to properties in Dyce, Kintore and Inverurie warning them of work in the coming months.
Residents have been told that preparation works will now be taking place for the next leg of the project for dualling the line between Dyce and Inverurie.
The work will include the creation of roads for access and work on retaining walls, and will include sites at Kirk of Dyce, Kinaldie, Inverurie and Kintore between November and February 2019.

Network Rail communications manager Stacey Macdonald said in the letter: “These include the use of excavators, vibrating equipment and deliveries of materials and the removal of spoil which will increase the volume of traffic. During this phase of work, 60% of activities will take place during the day.
“However, there will be key locations in which daytime work is not possible for health and safety reasons, and therefore work must take place at night when the trains are not operating to reduce the risks to our staff and contractors.
“The equipment we use means some disturbance is unavoidable, but we will make every effort to minimise any unnecessary noise through best practices.”
The letter goes on to state all sites for the project will be closed from December 21 until January 5 and overnight work will take place between 8pm and 7am Sunday to Thursday.
Closures to the track are expected to take place between Dyce and Inverurie in August 2019.
Residents have been invited to an information evening in Inverurie on Harlaw Road at the project compound.
It will take place December 4 between 4-7pm.
