the red light means stop. All junctions and control points are set with a defalt stop signal as a protection rule. If the signals display anything outher than a red light than a train is about to pass that location.

On railroads equipped with automatic block signals (and in some cases, at intermediate signals on CTC railroads), a green aspect can mean there is no train in either direction.
What is this topic doing in the photography forum?
Well it depends. If the default setting for that signal is perhaps an approach and you see a stop signal it could mean that a train is coming from the other direction. An example of this could be on CSX's Riverline at CP7. On the main track there is the 7N signal that when any train is in the block is yellow over red. But if a train is coming from the other direction on that track the signal will be lit red over red.
