context_page_description: Australian railway signalling varies between the states of Australia as each railway was established under the different colonial governments with separate legislation. As with the notorious situation of having different gauges, there are differing signal systems. New South Wales signalling systems generally follow British precepts, however American influence has increased somewhat since the 1990s. The Victorian Railways use Speed Signalling. This can cause confusion where the systems meet. For example, in New South Wales, Green-over-Red means 'Caution', indicating the next signal is at 'Stop'.
  In Victoria that same aspect, Green-over-Red, means 'Clear Normal Speed', indicating the next signal is anything but at 'Stop'. On the main south line from Sydney, Single Light Colour Light signals are now exclusively used from Spring Creek bridge to Albury on the Victoria border. This forms a buffer zone between the areas giving conflicting signal indications. Gradually the remaining Upper Quadrant signals are being replaced by Single Light Colour Light signals.
  South Australia uses two primary forms of signalling.
context_section_description: The railways of Victoria use a mix of railway signalling practices: British route signalling with home and distant signals (2 position signalling) and American speed signalling (3 position signalling).
  2 Position Signalling is still in use today despite its redundancy. Each signal is either a "Home" or a "Distant" Signal, where Home Signals can display a Red aspect that tell a driver they must stop, and Distant Signals display a "Yellow" aspect that warns the driver that a home signal up ahead is displaying a Red aspect. All signals can display a green aspect that means "Clear".
  Junction direction indications are given by displaying two aspects side by side on the same signal mast. Only the signal to the same side as the selected route will display the relevant aspect, while the other will be Red.
