168325 & 168113 head away from the camera at Oddington on 17 September 2017 with the 1Y56 18:11 Oxford to Marylebone Chiltern Railways service. With a constant procession of DMUs passing this location, there would normally be any reason to take a going away shot. However, I took this because of the fantastic lighting, which as can be guessed from the dark clouds in the background, didn't last for much longer. I particularly like the way the line of electricity poles stand out against the dark surroundings.
