View taken of the SMR NKP Berkshire replica as she awaits permission to exit the carriage shed road. The link line up to the station complex from the engine shed is on the left. The access to the complex is controlled by a signal on the main gantry from the signal box in the distance of this picture. The nearer box houses the communications and PA equipment and is manned at al times of public operation by a controller who takes charge of all dispatching and motive power decisions, movement control being carried out by the duty signalmen.
