😀 lol that’s an oldie! 🙂
By the way, I think the “Contract” scheme would be the fastest, plausible and feasible solution:
– you “sign a contract” with an industry
– industry starts production (volume still depending on goods demand)
– all cargo is dedicated to your line: no 20 min, wait forever on stations, etc.
– you pay penalties for every minute cargo spent waiting
I think this plan can be implemented without huge development time.
What do you think?
