66951 & 66606 run along the down relief line at Denchworth on 8 September 2014 with the 11:56 Neasden Charrington to Stoke Gifford light engine move. I wouldn't normally bother to photograph something like this, but with perfect lighting, and just the right size clear gap under the signal gantry, why not! It is also interesting in that it is a pair of Freightliner locos from two different sub-classes, both of which only contain a relatively small number of locos. 66/9 (7 locos) and 66/6 (25 locos).
