With the camera's ISO ramped up 66511 passes Roade with
a train of used track panels as the 13.35 Drayton Road to Bescot 6Y62. The track panels have been recovered from what I believe to be the up fast line somewhere between Bletchley and Tring in the vicinity of Cheddington. As the train passes under the A508 road bridge 390123 heads south with the 13.30 Birmingham New Street to Euston Avanti service.
