Line optimization

[Arkamaic]

Hey everyone.. So i have been playing comfortably for a little bit. Understanding most things.

The one I'm still having trouble with is line optimization, if I'm not being clear, its when the name of a certain line is blue, which means its making the most money it can.

I can get all my lines to be black, which means they are making money, but have room for improvement.

What are some tips/hints to get this?

I've tried adding more vehicles/cars and taking away trailers, adding trailers, changing wait times.. but i cant seem to get it. :(

Anything help is appreciated. *I have tried searching all the help sites and couldn't find anything.

Unless something was changed without me noticing, you're misinterpreting the colors:

Black is for lines which are profitable, and blue is for those that make profit, but have some outdated vehicles serving them.

Ah.. that makes sense. Then it's a good thing they never turned blue for me 

Thanks for the reply.
