A lightning strike has disrupted train services in Aberdeenshire.
On Saturday, Scotrail tweeted to say there was a fault with its signalling system in the Huntly area.
As a result, trains on the Aberdeen to Inverness line have been delayed.
Network Rail engineers found that a lightning strike had damaged some equipment in the area.
Scotrail has warned that trains will be disrupted for the next few hours while engineers source a new part to fix the issue.
