Scotrail has said that ground investigation work for the upgrade of rail links between Aberdeen and Inverurie is set to start next weekend.
The upgrade will see the current single track replaced with a double track later this year.
A spokesman from Scotrail said: “In preparation for the main work, some preparation activity will be carried out by Network Rail.
“This includes ground investigation to ensure the suitability and durability of the land, vegetation clearance along the route as well as delivery of materials by rail and road.”
The ground investigation will start on 20 January and much of the work will be carried out overnight.
The new higher capacity rail link is set to open by the end of 2019.
