Thank you. The white circles are called 'Headcode Discs' and are used to tell signalmen what type of train is approaching. At night these would be replaced by lamps. On the Southern network things worked slightly differently where there were two extra headcode positions on either side of the smokebox door whereas other regions only had three along the bufferbeam and one mounted as high as possible (in front of funnel or on top of smokebox door). The Southern headcodes were more to show where the train was headed rather than what it consisted of. While the one I chose was intended to represent a train originating from Folkestone (a place I visited in England in October), most people would recognise it as just an Express code.
If you were interested to learn more about them (and with a better explanation
) these two sites should help.
