Since I got this game 3 days ago I've been hooked to my screen, watching gameplay videos and browsing the wiki, while fooling around a bit with the first level of the campaign.
So now I decided I want to have a swing at freeplay mode, and try to make a bus design. I setup a double line of furnaces for both iron and copper, turned it on, researched the level 2 factory and fast inserters, and build this by hand. I turned it on, and so far it seems to be working. I do need to research the smart box and wiring though, to improve the production of the various inserters. They aren't getting quite enough green electronics as is now. conditions on the fast and smart inserter boxes should fix that, if I understand things right.
Please comment. Did I do something horribly wrong yet? Excuses for the many tunnels, which might obscure the main 4 iron / copper plate lines a bit.

Here's a closer up view of the basic production hub. I added a few spliiters to balance out the main lines after I posted the first picture:
