56301 passes through a frosty landscape at Islip on 13 December 2012 with the 6Z91 10:53 Calvert to Didcot Power Station flyash empties. Despite the gloomy conditions, I wasn't going to miss the chance of getting a picture of the Grid in this typical winter setting. Well worth the short wait in freezing conditions! Islip station is just beyond the bridge in the background.
