Underground belts can be used to split the left and right lanes of a belt. See this page from the Wiki:

Edit to add: This still needs two inserters. You will have to use red and green wires to limit the amount each inserter will put in the chest.

I am not sure how to answer you. You have made it to robots, so you are not a complete new comer. You talk about moving things around personally, which sounds like a beginner activity. Your question is pretty broad which makes it hard to make a brief answer or one that addresses the problem you enco...

But anyway, for what is the minimap in the Train GUI useful, if I can't use it to navigate to the stations I want to assign to the route and get their name from it? I find it useful when I forgot to add a train refueling station to one of my rail depots. "Now why isn't that train showing up?&q...

The code BenSeidel posted will kill all the biters and spawners in already generated chunks. When you explore more you will generate more chunks and they will contain biters. I am not sure if the pollution cloud will also generate chunks.

Which is way less cool :). Why not have the train do something useful if it is going around the loop anyway? You could put every station on the loop in each schedule, and disable/enable stations as resources are requested and available.... Wow. That sounds like lots of fun when you add a station.

Here are two cheaty ways that might help you. A. Use the console to do a scan even further away. 1. Start by loading a fresh save. 2. Enter this command in the console: /c local radius = 150; game.player.force.chart(game.player.surface, {{game.player.position.x - radius, game.player.position.y - rad...

That really sounds like you are not using 0.15. Just because everything new on this forum and youtube is 0.15 does not mean that it is easy to find. You have to specifically request the experimental build to get 0.15. You can check which version you are playing from the load game screen. Select the ...

You do not need circuits. Put a chest in the corner of the belt and have an inserter take items from the belt on the upstream side and another to put back in the belt on the down stream side. Kind of hard to explain without a picture, so here is an ASCII picture. bbbbbbb ....1.b ....C2b ......b Key:...

If you play with default settings the biters will come to you. Researching better defenses would be valuable.

When I've played with normal biters they seem to attack before I expect them to. As Hellatze implied, they attack when the pollution cloud gets over their base. If you create lots of pollution or have a small starting area they will attack quicker. If you burn trees you will create more pollution. T...

Trees capture CO2 in real life. Some people have made mods that allow growing trees. Some of these could reduce polution.

Nothing has changed for me.

What mods are you using?

Path B is a very long path. Version 15.0 changed rail calculations to make stations real long: Train station adds 2000 tiles penalty when path finding, so trains try to avoid stations not related to their path. Removing station 2 or removing a tile behind the blue train will cause the black train to...

I do not use Bob's, but with no mods I wonder if you are using a level 2 (blue) assembler. The level 1 assembler can only make items with two components. The inserter requires three components (Gear wheels, iron plate and circuit).

PacifyerGrey linked to a good thread on this. One thing that would help, if you want trains to exit both north and south, is to make the exit two one way tracks instead of one two way track. Your north bound would still be slower but south bound should go a bit quicker. I suspect that if you get the...

I was looking at this and found a surprising number of green circuit factories (35) were required to make one high tech science pack per second. I found this hard to believe and checked with a couple other tools and found an error. The number of blue circuit factories seems to be double. Calcorio sa...

I second Koub's recommended threads. F4 gives a menu of debug items. One of them shows which track pieces are part of which blocks. In your picture, it looks like the signal near the south most engine is a rail signal. This should be a chain signal to prevent the train carrying plate and coal from g...

It was taking a lot of time for the logistics bots to bring inserters and belts from the south end of the main bus where they were made to the north where I brought my builder train. So I decided to use active providers where they were built and storage chests near the north station. I made sure to ...

Not sure I'm interested in learning how to do pictures, but I move my red science to the middle of my belt until I'm ready to really start science. My belt goes: Gears Iron Plate Space for more iron plate space for still more iron plate Underground down Underground up Copper Plate. Space for more co...

If you have logistic bots available and do not have the requested number of turrets in inventory I do not know why you are not getting deliveries. Bots can take items from storage chests and both types of provider chests. They cannot take items from requester chests. The only way I know to find whic...
