[Experiment] Unloading 4 compressed blue belts per wagon.

[eradicator]

[snip] Satisfies all requirements of OP.[snip]

No it doesn't. It breaks tilability [snip]

7 tiles per wagon is tileable - you have to count the space between wagons, so as long as there isn't an adverse interaction (which there doesn't appear to be in this case) you can use 7 spaces.

Eh, please have another very close look at that design, it does not tile. I already noted that a splitter might make it tilable (though why care if my improved version doesn't need one). Theoretically 7-wide tilable designs exist, but i haven't seen one yet. Feel free to contribute.

Why exactly won't it tile? Are you saying something like this wouldn't work:

I dropped the latest tank design into a closed loop with 3-6 trains hauling raw ore to test it out (the same loop that sustains compressed belts with the last build I posted here). Unfortunately, despite the extra unloading inserter it still unloads too slowly to allow for the train cycle time. Adding a line of long handed inserters between the tank and the stack inserters does make up the difference though.

Please add pictures when linking blueprints for the sake of people not having factorio running in the background ;).
The wiki says 4 Long-handed are almost exactly 0.5 stack inserters. According to my shitty math you should have 2000/80 - 2000/(27.7*4.5) ≈ 9 seconds cycle time. Do you have proper inter-wagon signals on the stations? Because 9 seconds sounds feasible for a 3-6 (which is still too short for me anyway :p).

[disentius]

We can fix that:)
Durentis is right, we need extra inserters. His solution works, I have another one:

Nice :). I thought about abusing the "free" side spaces, but i couldn't come up with a quick solution so i gave up yesterday ^^. The two extra stackserters should allow a maximum cycle time of 13 seconds.

(But awesome as that is, I still don't like tanks being usable in this fashion.. -.-)

(I'm totally fine with them being useable, i just don't like doing it myself. Yet this build is so nice that i'm tempted to do it anyway (or at least code me an actual container with the same dimensions so i don't suffer the UPS overhead of cars :p).)

Also i wonder what the speed of inserter-2-inserter transfer is. If it's as fast as to-container you could skip the extra chests and let the corners do direct transfer.

[disentius]

it is a lot slower. quick test says about 70% of the chest to chest speed.
EDIT:
Still works in my testrig (no chests)

On a entirely unrelated note, [proof of concept] loading 4 compressed blue belts per wagon, 12 inserters per wagon
Hardest part was getting the inserters to behave nice.

First we had chests, then cars, then tanks. So the logical next step would be unloading into trains, right?

So here is the next idea:
1) Make a train station where the cargo wagons are diagonal.
2) Place cargo wagons next to it as buffer so 6 inserters can unload the train.
3) Transfer items into e.g. a tank and unload that onto blue belts.
4) copy the whole setup to the other side of the train station.

Unloading the train with 12 inserters but filling the tanks with only 8 should give some time to bring in the next train. So

5) Compute the time to unload one train, time to transfer to the tank and hence the time to bring in new trains. What's the maximum train length for full throughput on the belts?

[eradicator]

Dunno, the inserters seem to behave just fine without line splitting. You can also use more cars if you have spare ones j/k. Also i'd prefer the topic stays about unloading, not loading, as those usually have quite different approaches.

@mrvn: Make your own thread if you want to post a new challenge. Besides diagonal wagons can only have 4 inserters.

It's still the same challenge.

But if diagonal wagons can have only 4 inserters then that isn't a way to get the 4 inserters for a tank back to 6 per wagon.

I guess then you have to be boring and go: cargo wagon -> 6 inserters -> 2 tanks -> 4 inserters (2 each) -> 1 tank -> inserters to belts.

[eradicator]

It's still the same challenge.

Adding arbitrary new rules makes it a different challenge. And besides use of cars is explicitly discouraged for this thread. So please just stop this. It just makes the thread less readable for interested people.

It wasn't new rules. It was just an idea how to improve on the "4 inserters unloading into tanks" idea that has problems with the train cycle times. Meanwhile some else posted a design using a tank and 2 chests that brings it up to 6 inserters per side. So problem fixed.

Anyway, if the use of cars is explicitly discouraged what is the status on cargo wagons? Is using cargo wagons as buffer chests also discouraged?

[disentius]

OK. No loading. Check.

My reasons against cars are UPS and non-blueprintability. Blueprintability might be fixed for wagons in 0.17 (depending on if it works for wagons without locos), but i have no clue about UPS of wagons without locos. I'd suspect they're inbetween chests and cars somewhere. Someone should make a benchmark for that.

Yeah, I don't think that locos are required for blueprints in 0.17 (it would be really nice if it would work for all vehicles). I performance is dependent entirely on inventory size*access rate (i.e. inserters), but I may be wrong.

You are wrong. Cars "consume" more UPS than chests just for existing because of all the additional car logic attached to them (free movement, weapons, rotatable collision, etcpp). Just ask anyone in the car-belt crowd. Ofc it's not "oh noez my UPS dropped to 10" just because you build a hundred cars. But all the things add up. Though yea...the increased inventory size of cars (and the fact that they have more than one inventory) additionally makes them even more expensive for in/out-serting. I have my doubts about blueprintable cars becoming vanilla though. As far as i remember a dev said somewhere (quite a while ago) that they didn't want to give additional incentives to abuse the "weird" car collision boxes.

[golfmiketango]

Damn. totally forgot the unload to splitter thingy. thanks

Oh, God, somebody got a stack inserter plus a longhand feeding a car, and since you can put cars on belts . . .

Perhaps my empathy is just self-pity in disguise but I can't help but think this guy deserves a Fields Medal or something for implementing all that stuff.

Here is my submission to this thread:

Won't be balanced across chests when unloading though.
