Hi all,
to avoid opening many threads, I summarize in this post everything that I am unable to do in order to complete all the lines of my map:
1) find the "assign track to mark" option for road vehicles in the map editor
2) allow passengers to board
3) operate the AI buses
I swear that I have read all the lexicon, I've tried in every way but unfortunately I'm stopped here.
EDIT: I'm an idiot
I just managed to find out how to assign polygons to bus stops. Deem the first and second questions null and void
