ScotRail has announced that it will be withdrawing a number of services across Scotland on Thursday December 16.
Following discussions with Network Rail, the train operator is cancelling several services in the north of the country.
Both the West Highland and Far North lines will be temporarily withdrawn.
In addition, services between Aberdeen and Inverness are to be cancelled – but trains will run between Aberdeen and Inverurie and Inverness and Elgin.
ScotRail is intending to operate Edinburgh-Dunblane services as normal for the morning peak hours before cutting back the frequency of trains to an hourly service.
Weather conditions will be monitored throughout the night and timetable alterations reviewed according to the latest forecasts. Services will be reinstated depending on the actual weather conditions.
