After seeing 56312 at Launton on 31 October 2012 with the 6Z91 10:55 Calvert to Didcot Power Station flyash empties, I stopped off at Islip for another shot, simply because it was on my way home, and also I have very few pictures taken at this particular spot. The previous partly sunny conditions had now given way to miserably dark conditions with rain. The light level was not helped by this deep tree line cutting between the two road bridges. 56312 is pictured passing Islip in the gloom with the camera cranked up to ISO 1600.
