On 5 April 1997, a rockfall derailed a passenger service near Falls of Cruachan station on the West Highland Line. Thirteen years later, on 6 June 2010, boulders from the slopes of Ben Cruachan struck the Glasgow-to-Oban train at almost exactly the same site, derailing it again. McColl was on duty both times. The 2010 incident left one carriage hanging over a fifty-foot embankment, sixty passengers evacuated with minor injuries, a brief fire from spilled engine oil, and the A85 road and railway closed for a week. No one was killed. The mountain, indifferent to schedules and safety systems, had simply done what it has always done.
