In the very last rays of the setting sun and running 15 minutes early, 31602 Driver Dave Green passes Banbury stone terminal on 17 August 2009 with the 1Q06 17:11 Derby to Selhurst Network Rail Structure Gauging Train. I had correctly identified this location as the most likely local spot where shadows wouldn't be a problem, but of course you can never predict what's coming on the other line! An errant Voyager very nearly gets out the way, but just obscures the rear locomotive, 31465.
