Max Distance For A signal To Detect Occupancy?

[boleyd]

Is there a maximum distance that a signal will detect occupied track ahead?

The signals do not work on distance but on if a train is on the next track.

A train on the next track is determined by the gs tracksearch which can only extend about 32km or about 19.9 miles.

I am not sure what "next track means". Does it mean the same track but on a different part of that track. I am guessing that the program will look up to 19.9 miles ahead of a train for occupancy. If one or more signals are within that 19.9 miles the program only looks ahead as far as the next signal.
Thanks,

Quite often, subject to the distance mentioned above, it may look up to 3/4 signals ahead depending on the signal type (in order to display the correct indication).

yea that wasnt a very good description. whatever is using the gs tracksearch to find objects along the track spline can only go that far. the tracksearch starts at the object performing it, and either finds what it is looking for before the limit is met or it doesnt. a signal for example can detect a train or anything else for that distance, if another signal is found it typically stops there and lets that signal pick up its own search down the line but some signals may look for other signals to determine their states better. if a search is performed from a train to find some object it follows the same parameter generally but there are ways to specify the distance of the search up to that 32km distance. it can never go beyond that.

I apologize for the repeated message. I totally forgot about the referenced message.
