Here is your new perspective.
I do not know if there are any North American drivers in here but they are accustomed to call the dispatcher for all signal indications except green. You must understand that distances and accordingly time to travel are not in comparison to the Polish way of life. Most long haul transport is also freight, not passenger. (Big distances you rather travel by air.) Simrail is a hardcore simulation; I am not surprised if the peeps for the other hard core simulation called "Run 8" drive by and use their North American rules.
