56311 ambles along the Bicester to Oxford line on 6 August 2013 with the 6Z84 10:53 Calvert to Willesden Euro Terminal spoil empties. The train is passing Brookfurlong Farm, near Islip. But for the summer vegetation, this could well be the 6Z91 Calvert to Didcot Power Station flyash empties, that ran earlier in the year. Same loco, same wagons, and exactly the same time! Unfortunately the railway photographer's usual scenario of the preceding DMU being in the sun, and the intended train being in cloud, was in force here!
