56312 has been the regular loco working 6Z92 and the return 6Z91 fly ash trains from Didcot Power Staion to Calvert. After the train was unloaded at Calvert on Monday 3rd December 2012, 56312 failed whilst the train was in the loop at Claydon L&NE Junction. 56301 was on its way to Eastleigh and was diverted to rescue the train, though exactly what happened I'm not sure. Seen on Tuesday morning at Calvert at 11:04, 56312 is leading 56301 as they move along the main running line from south of the unloading gantry to collect the train from Claydon.
