Former Fertis Class 56 No. 56091 was in charge of 6Z92/6Z91 for the first time with the outward run on the evening of Wednesday 3rd April and its empty return on Thursday 4th April 2013. It is seen here departing from Calvert at 10:56 with the empty flyash train to Didcot Power Station, running with a reduced rake of fourteen wagons after some of the stock suffered problems with the buffers prior to the Easter break.
