It doesn’t. What matter is the amount of time the materials goes out of the mine or factory, walks it self to the station. Then picked up and the whole travel time to the next station, then walk it self rom the station to the factory or city.
The travel time is the same, no matter how frequently you pick the material, the travel time cannot be decreased, only with faster trains.
P.S.: Yes, what you said. I’m just thinking ahead. When number of trains doesn’t matter anymore because distance is too far. And for that, distance doesn’t need to be that long. That is what it bother me. Plus if you increase frequency to try to reach TTT under 20 min, is when you have train with few wagons.
