56303 rounds the curve at Islip on 26 April 2013 with the 6Z91 10:53 Calvert to Didcot Power Station flyash empties. No apologies for yet another picture of this train, as Devon & Cornwall Railway's involvement must surely soon be at and end, as the closed Didcot Power Station is obviously no longer producing flyash. This location, at Mill Lane level crossing, has recently been cleared of vegetation in readiness for the Oxford to Bletchley route upgrade. I was extremely lucky with the sun here, as by the time I had walked the short distance back to the car, it was raining!
