66097 passes a field of oilseed rape near Uffington on 24 April 2021 with the very late running 6C03 10:33 Northolt Sidings to Severnside Sita Binliner. This should have passed here over 2½ hours before the 6B91 12:34 Hayes & Harlington to East Usk Yard stone empties. Instead of that, because 6B91 was 91 minutes early, and this was 103 minutes late, it passed half an hour after 6B91! The delay was caused by the failure of the cab radio in the train's original loco (66096), so the loco was swapped for what turned out to be he next highest numbered Class 66, at Didcot.
