After a largely sunny day, the haar (coastal fog) is rolling in from the sea again and blotting out the background as 170412 weaves round the reverse curves at Cauldcots with the 17:00 Dyce to Edinburgh First ScotRail service on 5 May 2008. In fact as I was waiting for this train to appear, lees and less of the village of Inverkeilor in the background could be seen.
