56312 worked the first loaded 6Z92 18:12 Didcot Power Station to Calvert flyash train on 30 October 2012. The following day I went to Calvert to get a picture of the returning empties at the unloading terminal. The loco is pictured prior to working the 6Z91 10:55 Calvert to Didcot Power Station empties on 31 October 2012.
