Rail demo contains no loops, 10/10. Seriously tho, that's awesome.

I'll try to help you figure what's causing that leakage flow. There are two reasons that I can think of. The first is flow direction. Fluids flow left and up first, then right and down. Orientation matters. Yes, it's a lot like redstone in Minecraft. A simple solution is to disconnect the undergroun...

Can you scale it up? Well, yes, simply use the version shown earlier, with 2 tanks, 2 output pumps, 14 boilers and 10 steam engines. It doesn't need the constantly powered input pumps, as an offshore pump = 2 small pumps. That can control and supply up to 170 pumps (85 lines of 14/10). I don't have ...

In the game code, locomotives have a weight of 2000, and cargo wagons 1000 regardless of what's IN either. Every unit has a "friction" value, and I believe its the same for both. Power-to-weight ratio is not the sole determinate to acceleration and top-speed, as the added friction from len...

I've done something very similar a few months ago. Why use water mixing instead of combinators? Instantaneous pickup in a very simple manner. I like your design... it reminds me of mine

Much better. I don't see and light to solid fuel being made, just a gas dump. Oil is kinda hard to balance, but those wire conditions sure do help.

I'd get rid of all those crude oil storage tanks. Literally all they are doing is taking up more space than you need. You can store a LOT more oil in barrels in a storage chest than you can in a storage tank, and you're already using barrels so why even have the tanks? Also, I consider it a sign of ...

The way inserters place items on belts changed between 0.11 and 0.12, so plan accordingly:

Okay, it actually makes me excited that something I've done is the top result in a google search so sit back and enjoy the link: http://bfy.tw/1sLB

Go to edit 3, revised designs 1st set, which is this if you don't want to go through the trouble.

Feedback to improve the factory? First off, I consider the train system a mess. Loops, roundabouts, vertical stations, less than max inserter count stations, all of these things I consider sub-optimal. You have 4 belts for each ore. You can completely fill it with a properly designed single 1-4-1 or...

There is either not enough power draw, or too many boilers, in that self-contained system. Each boilers can support 13 pumps, so unless you have 65 lines up there, you're heating up the water too much. Steam engines behave oddly in small systems like that. They will actually consume less than 6 wate...

[*]The double row of long handed inserters should be faster than a single row of fast inserters that people normally use, but I have not tested this myself. This is something I have tested, and thoroughly. Back in 0.11, double rows of long handed inserters was 50% faster than a single row of fast i...

This is perhaps my least favorite unloader design. Unnecessary: mingling of products, buffer system, lane reblancers. Ineffective unloading (if you aren't using 14 inserters loading directly into chests per wagon it isn't optimal), mixed trains... All in all, a really horrible design that I don't th...

Double headed trains yes, single track no. You can still use that 2-lane system, but without the loops and roundabouts. They really just take up a lot of space for no real benefit and are more difficult to expand later.

If I don't have blue science set up by the 3 hour mark, I consider it a failure. I believe we got that far by the 2 hour mark in the speedrun. You have the seed and map settings, if you think you can do better, go ahead :) I'd love to see someone beat my time. Edit: the terms are as defined by the c...

It doesn't help that the math was wrong, as well. You can't have an output lane more than 100%. In the actual game, the back pressure would build up and force the other side of other splitters to output more, so an iterative process would be needed to calculate what really happens. Well, in previous...

Why do you think, loops are unnessessary? It contains loops, so that a train can just go whereever it wants to go without using a longer ways, instead of going the complete was back to the mainstation. In that way you can create a train schedule with more than two stations. That was the direct repl...

Know your meme, Factorio edition! It all started here and spread from this very forum into other twitch streams. From there, it experienced the memetic mutation from "5/10 contains loops" to "4/10 contains loops" then spread to reddit. Finally, it spread back to this forum, compl...

The roboports still have a power death spiral problem. True, but they have a rather large internal charge, and high priority on power to recharge. Have you factored in the pollution cost of mining coal? No, I considered it "negligible" but feel free to calculate the pollution of miners to...
