A group of rail workers narrowly avoided being struck by a train travelling at 125mph in Dumfries and Galloway.
They were carrying out a track inspection south of Kirtlebridge, on the West Coast main line, when they had to flee to safety.
No-one was hurt during the incident, which involved a Virgin train and happened just after 9am on November 14.
