Just before sunset on 29 July 1999, 66129 has a clear path along the down main line at Circourt Bridge, Denchworth, with the 6C72 20:03 Didcot Power Station to Avonmouth MGR empties. In the 1990s the vegetation on the north side of the line consisted of just a few small bushes and lots of Ragwort. Later a line of trees would cause shadow problems here, even before the 25kV catenary completely blocked out the view.
