This is what happens when you don't maintain your locomotives properly. Because DB Schenker are reluctant to invest in their Class 60 fleet, in particular the heavy overhauls that the 20 year machines require, early 2010 sees only a handful of the heavy freight locos in service. The result is that heavy oil trains from South Wales have to be entrusted to pairs of the inferior Class 66s. 66140 & 66126 pass Circourt Bridge, Denchworth on 30 January 2010 with the 6B33 12:12 Theale to Robeston Murco oil empties. At least I suppose that it now means that having got this picture of the double headed working in good light, there will be no need to venture out to the lineside to see this particular train again until commonsense prevails and the correct traction is reinstated.
