Has anyone considered having a train long enough to be loaded by multiple patches? Load e.g. 4 wagons per patch then advance the train by 4 wagons and repeat till it's all full. Or have lots of locomotives to fill the gap between patches or simply leave cars empty.

I do not think this would help. This technique would reduce the total number of trains at the expense of more rolling stock. As the biggest UPS hit from trains is for the collision checks on the rolling stock this is likely to be a bad trade off.

Although it would look fairly cool!

I'm not sure any kind of buffer chest will be efficient enough to win.

No cars, no belts, no buffer chests. Just direct inserting everywhere.

Nice work DaveMcW. Just waiting to beat us all until things had stagnated a bit .

For those who are interested, there's been a lot of design discussion happening in the Technical Factorio discord: https://discord.gg/8RqPQYM

Congrats on the sub 40 second time, Dave.

what my brain is like after the last few entries:

It isnt going to beat dave (the master) McW

But here is the latest refinement of my train map. I have reordered the smelters so the smelter with fewer beacons is in a different place on each row, this has made a huge difference of over 0.1 ms / tick on my pc. (from .486 -> .367) the other changes are largely cosmetic.

Well, looks like I have some catching up to do.

flame_Sla is now the leader in "belts only" category!

I took the liberty of cloning each design up to 1M/m since performance scaling is often not linear.

I ran each map until it appeared to be stable, then took a save. For trains this meant long times, belt based designs not-so-much.

I cloned each map in a chunk aligned manner so it's unlikely that positional asymmetry creeped in.

A few maps remained fairly unstable, or didn't quite reach 1M cleanly. Take with a grain of salt.

Anything entitled legalized (to vanilla, not this contest) means I modified stuff:
- moving the character probably to not gen chunks
- making all cars active

Aside from that everything was brought up to 0.17.75.

I made a *very* marginal improvement to my belt-only build.

Well, I was going to do this, but it turns out my build would require more ore patches and I guess I would be allowed to add more, but at that point I'm just not interested enough. Probably wasn't gonna work.

What did you have in mind? I thought my build took up quite a lot of room, but it still only took up 9 patches.

If your build involves putting max beacons around every mining drill, I confirm it won't work. At Mining productivity 44, a beacon boosting only 1 mining drill is a net loss of UPS.
