37602 passes Baulking in a lucky patch of sun on 17 August 2009 with the 1Z12 08:57 Derby to Bristol Temple Meads (via Oxford and Newport) Network Rail radio survey test train. 37218 can be seen on the rear of the train. Having already seen the train at Denchworth, there was plenty of time for this second shot, as it waited in Challow loop for 45 minutes.
