just hook unloading inserters together, set them to output their holded item(s), select "hold" mode and then you only need a circuit that outputs something as soon as the inserters output 0 for longer than one second or use inactivity if you only touch one of the cargo wagons at this stat...

This new condition is in my eyes too specialized to have it as general case in the vanilla; especially cause you will have (at some time) an alternative: to implement such a "specialized" condition would be to built a circuit network and set the train to wait for that circuit condition. I...

Is it possible to add a condition "at least one of the cars is empty" to train stops? I have 4, 6 and 8 car trains to haul the most common resources. I have also standard belt balancers between unload stations and consumer devices. But they do not balance perfectly in that direction and ty...

The only issue I have yet to fix is that in some instances, the drills pick up more than one item. For example, say an iron patch, and there's a bit of copper tucked in there somewhere. I sort everything before I put them on load chests. I try to avoid placing miners on spots where they can produce...

You should set filters in cargo wagons too. Open the inventory window and click a slot with middle button. Select what stuff you want to be in that slot and copy it by normal shift right & shift left operation to all slots. I use always filtered slots in wagons and and filter inserters in unload...

In my opinion advanced oil processing should be the first goal after unlocking basic oil processing. I use always 1 refinery and 1 plastic and sulfur plants in that phase just to produce everything needed for blue science and advanced processing. After that I make a large overhaul and expansion in m...

As far as I know there is no such simple way to prevent expansion in vanilla game but there is a mod for that.

For gameplay terms I guess that nuclear would be just over powered. One 3x3 tile reactor would give at least 250 MW in case of a molten salt reactor (MSR), make no pollution and zero waste (considering that nothing else leaves waste in the game). The mods that use cooling towers etc are just not re...

I think that portable fusion reactor can be renamed to some kind of RTG and it could have exponentially decreasing power. Half life could be for example 3 hours so that player should change them occasionally but not too often. I like also the idea of nuclear bombs. They should be extremely expensive...

Is it possible to change autosaving such that when autosaving time limit is exceeded game waits until player have not moved or pressed buttons for example in 3 seconds? It would prevent most annoying situation in which autosave happens at worst possible moment.

How in your opinion pathfinding should predict the time needed for waiting? It may be too complicated thing to be taken into account. I think that devs do not want to make a large overhaul to train logistics. It would be enough that path finder would compare distance between the shortest free path ...

I bet there are no "roundabouts" for trains anywhere in the world. It's not realistic. But there are several possible routes between cities in every country. I did not mean very realistic traffic but as realistic as practically possible in Factorio. I would like that there would be a poss...

Your network contains loops. 4/10 I know that tree structure would be more optimal in Factorio. However, I want to make more aesthetic, realistic ans practical rail network. It is not huge problem if some train uses couple of extra minutes. However, it is annoying and it would also be very easy and...

Trains have strange logic that if the shortest path is temporarily occupied they calculate an other path. It is problem because I want to make realistic like rail network (and also practical to run from an outpost to another by the work train) which have many routes from station to another. Sometime...

I set filters in car next to the locomotive. I use always filters in resource trains because sometimes trains can stop on wrong stops. I put some requester chests to unload station in the base and load the car with supplies. I unload them to provider chests in outposts. I use one chest per item type...

I consider expanding. I have done it already in couple of steps, my original idea was capacity of 2 full blue belts of iron (about 5 k/min). I have widened my iron bus from 2 to 8 lines, moved most of my production cells, moved rail yard, expanded my base etc. (therefore the layout of my base is som...

No, but it is easy to filter one slot in a car for construction bots and use circuit networks to unload them when needed.

OK. Thanks for the information. I will not care about old belts.

I have a relatively large base able to produce 700 k iron plates per hour and launch a rocket per 5 minutes. It is quite compact, quite optimal and quite aesthetic with concrete tiling and runways. I have isolated about 10 square kilometers by tough defense line. No enemy have ever came through it. ...

I make outposts with solar electric system, mining drills and defenses and bring resources to my base with trains. I put also roboports and repair bots to the outposts immediately or later depending on the research situation. Later I conquer larger connected area, typically couple of square kilomete...
