165109 passes Lock Wood, near Culham on 10 December 2012 with the 1P43 11:50 Moreton-in-Marsh to Paddington First Great Western service. The line of the trees in the background is just a small part of Lock Wood, which runs down the steep escarpment on the south side of the River Thames. Ironically, there hasn't been a lock at this location since the eighteenth century.
