I feel like when I hit around 80k population I kept noticing so much cargo trains just trying to get into the city non stop. If you notice some part of the video I added an extra track next to the other so I can separate the cargo from the passenger so at least the passenger trains can go smoothly, obviously it's kind of wanky because I had to do adjust it while trying to avoid the already developed city around those tracks. I want to know if I did something wrong here, if something is wrong with the game, and what I can do to fix it. Maybe my track structures just suck but I don't have any idea to improve it further without heavily affecting the surrounding districts.
