I recently re-discovered TTD after seeing someone playing the game on a train . I'm still new to the game. I have on question: How do i increase the primary industry output?
If you provide good service (at least 67% transported, I believe) the industry will have a 67% chance of increasing its output when decides to change its output.
If you don't, the industry will only have a 33% chance of increasing its output when decides to change its output.
