66126 passes South Marston in fading light on 15 July 2016 with the 6O17 16:32 Barry Docks to Dollands Moor. This train runs from Associated British Port's recently opened intermodal container terminal, and often conveys empty polybulk wagons, which are used for conveying silica sand. However, on this occasion the train is a more or less uniform rake of containers (two per wagon).
