Oh, that's interesting. You are remote manufacturing components.. I think most people just truck coal and super-long-belt everything else, haha. If you need to deliver deeper into your base I can see the size issue. Maybe you can just settle for trucking to the open base outskirts and minibusing to the compartment? Or perhaps ship to a main bus system?
Also, how has trucking worked out for you in spite of space concerns? What would you say are the benefits of shipping completed components and avvoiding megabelts?
