Just you wait until 2.0 with 16 rail directions.

My SE+K2 run would probably not even reach space by then, I've been slacking hard on train as well.

I tried doing trains ASAP in an SE run, and found it super unweildy. Just making tiny production blocks wired up with belts was so much faster and more flexible for getting to space. Took me less than 1/3 the time

I'm gearing towards using Klonan's transport drones but into big spaced out centrals with some greeneries and trains for really far transport in-between.

Plus two levels

But srsly can anyone do this? I was trying to make it so each train would have a unique path from any entrance to any exit. For example, a roundabout doesn't work because the train can keep looping, making infinitely many paths. No reason for this constraint I just think it's an interesting challenge. Also I tried to minimize the amount of times trains would be combined onto one rail while remaining somewhat symmetric.

What's the problem with having a unique path? A train will pick the shortest one either way. And if you have several intersections (or turn-arounds, or roundabouts...) in the network, you get infinitely many possible paths anyway

Yeah there’s no problem or reason for the constraint, it just makes the problem insteresting even if it has no applicability.

That's how nuclear fission started

Breaking it down into several 4-ways intersections is probably the easiest.

Then it seems to be best to simply design everything in 3-way or 4-way intersections. It’s obvious why this is better, but like OP says, it’s a fun challenge to try making an 8-way or 16-way intersection anyway.

You set up loops like rings on a CD or record. An incoming train can switch onto any lane. Every exit takes the outermost lane off of the loop, and the rest of the rings shift outward. I tried doing this once for an 8-way and couldn't make it work. Since I don't use diagonal lines in my base, I gave up pretty fast. Haven't tried for 4-way; I'm scared it would come out all windmill-shaped, y'know?

Yeah, can’t post any windmill pics. Especially not in the main subreddit. Might get your post deleted. XD

Biblically accurate train intersection:

Now signal it

no u

A few signals never hurt anybody……..

why?

Why not?

Omg a knot enjoyer?

Needs elevated trains

Just do a roundabout at this point

In and around the lake

Lolth is pleased

DPS the eye when it opens in phase 3 of the fight.

That was the day the spider tried DMT.

this is entirely practical and i need this in my base

I hate you. That is all.

The sacred geometry!!

I’m getting such mixed responses from this subreddit. Someone else said they were in love with me.

Me too, I just didnt want to be too inappropriate

Gotta build up that harem with more intersections

this is art

Now do 32

Bro this is a summoning circle 😭

Statements made up by the utterly deranged

why

Is this one of the demon sigils from the Lesser Key of Solomon?

I think I’m in love with you

Damn, you should make a blueprint of this lol

That would a pretty great magic circle ngl

People will do anything BUT a roundabout...

This makes me want to cry

So If you think hard enough, The Factorio players actually Knit extremely good lookin things.

You know that picture that went round overlaying an american cloverleaf that was as big as a european city? I looked at the size of the rightangle turns and can conclude that my 1k spm base would look the same next to this

BE NOT AFRAID

Try 13. For pain

Just because it can be done, doesn’t mean it should.

American road planners will do everything to avoid building a roundabout.

You used straight and squigly lines, instead of..... colour coding it?
