According to yesterday's Press and Journal...
An extensive hill fire on an internationally-important Sutherland nature reserve yesterday was last night blamed on sparks from a passing steam train.
A helicopter was brought in to help firefighters by water-bombing the outbreak which was still raging as darkness fell.
Units from Helmsdale, Thurso, Bettyhill and Tongue joined RSPB staff in fighting the peatland blaze which had a three-mile front at its height.
The bird charity was very concerned about the potential impact on the reserve’s rare bird life as it coincides with the start of the breeding season.
The outbreak was found just before lunchtime on the 20,000-hectare reserve based in the tiny community of Forsinard.
It was reported minutes after a steam train, on a charter run, pulled out of the village station.
