In a very brief burst of sunshine, 66239 shunts flyash wagons at Colnbrook on 12 March 2005. The flyash arrives from west Burton Power Station and on this day the shunting operations at Colnbrook had to be suspended for a while as a Class 37 hauled railtour came down the line on the left, and stopped with the train fouling the point that 66239 is seen approaching here.
