56312 pulls slowly away from Calvert on 31 October 2012 with the 6Z91 10:55 Calvert to Didcot Power Station flyash empties. Empty is a relative term here, as they did not have enough time before the booked departure time to unload all the wagons, and so some flyash (clearly visible in the second wagon) is heading back to the power station! I had gone here as it was a dull morning, and this would be a problematic location if the sun came out, as it is looking virtually straight into the light. Needless to say, that is exactly what happened!
