Issues with worker delivery subsidies
Bit confused as to why I am finding these extremely difficult. Early game they seem like easy money but around 50 years into the game I am finding I can't complete a single one. I set up 2-3 routes from the nearest towns into the industry with 2-3 buses on each spread so the wait times aren't to long but I never get any demand from the towns so all buses just run empty or almost empty till I fail the subsidy.
I am struggling to get over 6/10 for almost any subsidy. It seems like a few years afterwards I am getting 10/10 at the industry but it seems to take ages for the demand to build up. Any ideas on what I'm doing wrong or tips to work on these later in the game?
