https://mods.factorio.com/mod/train-trails gives some of what you need in a fun way.

You could also achieve this with basic combinator circuits and display panels scattered around the map.

In the most general form, what you're asking for is a huge amount of data (a usage number for every rail ...

Repair pack and fix it?


Sure, but how do I grab it, physically? You can't select for partial health things to deconstruct, or to grab with an inserter. If you right click on it when an inserter is holding it, it just gets dropped into a yellow chest, and then it arrives again, eventually. I ...

It might only apply when renaming stops with no custom color already set.

Train stations will automatically adopt the color (and train limit) of stations with the same name when you rename them. Haven't seen anything letting you change the color in a blueprint or circuit function.

You don't even have to wait. As soon as the deconstruction order is placed, the signal becomes deactivated. Let the train drive past, and undo the order.

Manually driving the train through the signal IS the button you are asking for. There is no instance where the train should just continue immediately after the red signal like everything was normal. Fix your signalling, drive the trains to where they should be, then set them all back to automatic.

The alt mode icon position can be adjusted by https://lua-api.factorio.com/latest/prototypes/EntityPrototype.html#icon_draw_specification.

This mod tries to make icons less obtrusive by modifying the icon shadow: https://mods.factorio.com/mod/Humble-Alt-Mode-Shadow-2

Ah, thank you! I didn't notice that that part of the preamble is part of the API definition, not merely explanation.

Maybe add support for dragging items across logistics groups?

I also had this issue switching between normal and legendary sciences. My problem could be solved with an "active science" group and an "inactive science" group and dragging items across them.


You can pipette to copy entries in ...

I discovered that ghost infinity chest/wagon/pipe filters can be interacted with just like ghost logistic chests. The following entries should have the note "Also works for ghosts", similar to LuaEntity::get_inventory_filter().

LuaEntity::infinity_container_filters
LuaEntity::remove_unfiltered ...

You can put the same item in more than one group. If you need belts but not splitters and umdergrounds, just add a new section and put it there. Or do like I do, and have the first group be for items I set individually, and the following sections for things I control as groups.

The headless server build already includes the DLC files, so no copying is necessary. Just create a Space Age save file on your client, same the map, and transfer it to the headless server saves directory. It will automatically load the DLC when it detects it in the save. (At least that's how it ...

SelectorCombinatorParameters states that quality_source_static can be specified as type QualityID , which can be either LuaQualityPrototype or the string name of a quality prototype. However, both read and write of quality_source_static are done with a table in the form {name=<quality name>}. This ...

As Loewchen said, use the tutorials and place signals without worrying about priority. Once you split each intersection (each of your pictures shows one "compound intersection" that should be signaled together) with chain signals, and place rail signals at each exit, train pathfinding will produce ...

You can register your Steam purchase on Factorio.com and download it directly from there without using your Steam password, but you are correct that only the Linux headless server package is available without logging in.

It's not stuck. Once the output is emptied of the recipe product, then the spoilage will be moved to the trash slot. It's like this so that idle machines don't constantly load more ingredients that spoil inside them.

Tl;dr it's more work on the backend, especially navigating the full dependency tree, but hopefully they can add it eventually.


I don't think it would need to navigate the full dependency tree, just slap the label whenever a mod is uploaded that adds a dependency with the label or enables a ...

When the configuration changes, the game automatically recalculates which recipes should be unlocked based on all the technologies that have been researched. That way, if a mod adds a new recipe to an early tech, it gets unlocked immediately.

In your case, the recipes are not unlocked by any ...

Why should the robots waste explosives if they can mine it directly?

Is your actual intention to make a cliff that players can mine but robots cannot?
