these are the colours
yellow = hypertube
pink = train
green = signal
light pink = conveyor

check out the youtube vid i made - it shows the factory in the map in real life, should make more sense.

I like to build 'with the environment', so it's not one of these floating factories, its a bit more complex. And its more of a logistics hub than a factory really, all the factories feed it by train and conveyor.

I'd need some proper education about these color codes.

I am sure I could learn a whole lot from this one picture.

I tried at many locations (except this cliff) and run each and everytime into space problems.
To dismantle everything and build everything fresh 30 meter higher doesn't feel great. And if you leave your stuff down there and build a new level up there everything down lies in the shadow.

I am a bit in a demotivated phase now and try to figure out where and how to start next. Not a new game start but a new base start. That cliff makes a great impression but it feels so shitty to leave half a dozen other bases back and unfinished. If that makes any sense to you.

It's mostly over the southern end of the harbour which allows you to connect to all the nodes on both sides.
Quartz from the top of the cliff to the east (and processed comes out by train through the tunnel to the west)
Copper lime coal and iron are also on both sides. It's an epic location.

is you base on the cliff (with 3 pure iron + 1x lime and 2x copper and 2x quartz a bit down and 1x coal a bit futher down and 1x sulfur again a bit further down at the lake) ?
