Thank you very very much guys,
I badly explain you my problem, see picture at the bottom (picture 1) ... I need something like this but I have 2 tracks but in fact it is simillar. I have scripted signals, and I need allow entry TRAIN into mid-station section where is located automatic block signals.
In station "AAA" I set path for train1 to station "BBB". Then I need block all signals in station "BBB". Perfect function has yellow marker because if his direction is against train signals are blocked. BUT there is this problem - I really need by rule or script ROTATE (change direction) of this yellow direction marker. 
Im from Slovakia I dont know how is it named in English but in Slovak it is "TRAŤOVÝ SÚHLAS" ... in English something like " TRACK CONSENT ". 
In picture 2 the first (yellow track means that there is something wrong and track is closed), train 12715 must go throught only one possible track. 
In picture 3 is situation where track 1 and 2 is open (normal state - 2 way traffic).
I really need manage track consent in trainz, best option will be if will be possible ROTATE DIRECTION MARKER (yellow marker) or ADD and DELETE by SCRIPT or RULE. 
Do you understand me what I want to do in trainz (track consent)?
