The plan

Here is the railway's line diagram of the area, showing the position of all relevant features such as points,catch points,signals and the relation between the railway areas and the surrounding roads. The single line(from Sydney)appears at the top and runs to the station and 2 sidings at bottom. There is also a long storage siding from the station that leads back towards Sydney parallel to the single mainline.

I know the basic order of train operations for Cronulla as it was, but intend to go there and speak with the stationmaster, if possible, to find out more.
