A most unwelcome sight at Uffington on 12 February 2008. Instead of the usual Class 60, 66145 turned up on the 6B33 13:30 Theale to Robeston Murco oil empties. Whether this poor choice of traction for this heavy train (admittedly now within the capabilities of a 66, as it is empty) had anything to do with what happened next I am unable to say.
