Vegetable oil powered 66004 pulls slowly away from a signal check at Didcot North Junction on 10 October 2022 with the 6E11 12:00 Appleford Sidings to Milford West Sidings containerised flyash empties. We were very lucky to get this in the sun, as while it was sat at the signal it was alternately in sun and cloud, and just after it had passed the sun disappeared again.
