66745, 14.07 Bescot Yard-Wolverton (via Wembley) (6G57, 48L), site of Roade station
With the converted 'slinger' wagons resplendent in their bright yellow
paint contrasting with a menacing sky the 14.07 Bescot Yard to Wolverton (via a seemingly pointless run to Wembley and back) passes Roade. 66745 is dead on the rear of the train but will lead the infrastructure working north once it reaches London.
