Thanks. I think my issue was that I couldn't understand why I would avoid deforestation...
Maybe it's silly, but it's weird to have a unit of resource that doesn't clearly correspond to any of the units it's consumed in, so maybe there should be a way to see a train's consumption in MWh/cycle or something, just so that number has any frame of reference. Or maybe I'll just get used to it.
edit: another suggestion with logging camps... it would be cool if trains could automatically recognize a "moved" logging camp as the same one, so that I don't have to find each train that was going to the old location and update its orders.
