The first day of February 2010 was very cold and the preceding week or so was equally cold, so cold in fact that Lindores Loch was frozen over. Looking across the ice is Network Rail's class 150 sprinter test unit 950001 working 2Q08 0400 Craigentinny to Craigentinny via the Fife Circle, Dundee, Perth, Westfield, Alloa via the Longannet branch!! Here it is running late heading from Perth to Westfield.
