Hey!
I don't know if it is a bug, but: At my visit in Katowice I noticed, that trains departing from platform IV track 10 to Katowice Zawodzie they get green signal (S2) at signal M10 and E18. Ingame you get signal S12 or S13 at signal M10 and signal S10, S12 or S13 (depends on entry in Zawodzie) at signal E18.
Irl that was a train to Krakow, so it was driving straight ahead to track 4 in Katowice Zawodzie.
As I mentioned, I don't know if it is worth a bug report, but thats what I noticed. Maybe it was renewed between the SimRail-Time and now, but I don't know.
For further "evidence" I searched a cab ride with timestamps. Signal M10 is seen here, signal E18 is seen here.
Here is a video from ingame: click
