I take it you mean the bus stations? If so, I’d recommend scrapping them as they can only hold a certain amount of passengers (no limit for those on the street) and you can only assign one stop to a line.
bus stations and truck stations. dock selection is needed for both.
I note the limit for the amount of passengers in big bus stop (I wasn’t aware of this limitation) ==> Should be good to have a manual from the devs with all these details that you’ve to learn by trial-and-error method.
How come you say “you can only assing one stop to a line” ? I assign more than one line to my bus stops.
