DCR (Devon & Cornwall Railways) No. 56312 had run DIT from Doncaster the previous day behind 66005 with 20 empty MBA box wagons to Didcot, arriving very late. The wagons were supposed to be loaded with fly ash at the Power Station but due to lack of time the train ran empty to Calvert as a trial run as 6Z92. It is now returning as 6Z91, 10:55 from Calvert to Didcot Power Station, here approaching Islip station at 12:30, a few minutes late. Tuesday 30th October 2012. Digital Image No. GMPI12767.
