Rogiet were owned by the railway and were only rented to railwaymen. Engine sheds To support the marshalling yard, the junction and the need for banking engines on the tunnel line, a large engine shed developed near the station, towards Caldicot. This closed in the mid-1960s with the withdrawal of steam traction. A far smaller diesel traction maintenance depot replaced it, now only needing to support far fewer locos. This was on the other side of the station, towards Undy. The depot codes were 86E and ST. The main engine shed was located to the north east of the railway station, while the goods yards were to the west. From 1955 to 1974, Class 08 shunters, British Rail Class 14 and 37 locomotives could be seen at the depot. The steam sheds, their turntable, coaling stage and water tower were demolished in the 1960s. The land remains empty and derelict although it was used as a storage depot for new cars during the 1970s, and more recently as a works yard during the electrification of the South Wales main line. The goods yards were located on both sides of the running lines, one for each direction, and used hump shunting to sort individual wagons into trains.
