Better fuels make a locomotive accelerate faster and run faster: solid fuel gives ×1.2 acceleration and ×1.05 top speed, rocket fuel ×1.8 and ×1.15, and nuclear fuel ×2.5 and ×1.15. Wood (2 MJ) and coal (4 MJ) set neither. factorio-logistics/fuel-bonuses

A train's top speed is the average of its rolling stock's top speeds times the average fuel bonus of its locomotives. Wagons set no top speed of their own and drop out of the average, so a train of base-game locomotives tops out at 72 tiles per second on coal and 82.8 on rocket or nuclear fuel (1.2 × 1.15 = 1.38 tiles per tick). factorio-logistics/train-top-speed

Tier 2 because the averaging rule is Wube's documented statement of engine behaviour; the values it combines are read in data. Acceleration also depends on weight, braking force, friction and air resistance, which the engine combines in ways the API doesn't spell out.

Rail signals cut the track into blocks, and a train may enter a block only when no other train is in it; signals keep trains from colliding or blocking each other, while the train already knows its route. factorio-logistics/signals-and-blocks

About: Factorio Rail signalling

Cited by: Factorio, Rail signalling

A chain signal holds a train back not only when the block beyond it is occupied but also when the exit the train will take out of that block isn't free, so a train doesn't enter a junction or a shared single-track section unless it can leave it. factorio-logistics/chain-signal

FFF 81 (2015) announced the chain signal for 0.12. The rule it states is the one the 2.1.23 chain signal still keeps; nothing later that we read changes it.

A train that would have to stop at a red signal tries to find a new path; that is the only part signals play in pathfinding beyond the penalties below. factorio-logistics/repath-at-red

About: Factorio Rail signalling

Written in 2015; the wiki's 2.0 list of repath events still includes braking for a signal the train can't reserve (factorio-wiki-train-path-finder, "Repaths that happen as part of normal train operation").

Cited by: Rail signalling

The train pathfinder searches the rail graph, from both ends of the train when it can drive either way, for any stop with the scheduled name that isn't disabled, scoring each rail segment by its length, plus a penalty for an occupied block of twice its length divided by how many blocks it lies from the start. factorio-logistics/path-cost-length

On top of length, a path pays fixed penalties: 2000 for each train stop it passes, 1000 for a signal the circuit network holds red, 500 for a train standing at a stop (1000 if it has no other valid stop), 100 for a train arriving at a stop or signal, 100 plus 0.1 per tick waited for a train waiting at a signal, 1000 for a train with no path, 2000 for a manually driven train stopped with a passenger and 7000 without one, and 7000 for an automatic train with no schedule. factorio-logistics/path-penalties

2.0 added schedule interrupts: each has a list of conditions and a list of target stops with wait conditions. When a train is about to leave a station it checks its interrupts in order, and the first whose conditions hold pastes its targets into the schedule as temporary stops. Interrupts are shared by name between schedules, and one can't fire inside another unless it has the "In interrupt" condition. factorio-logistics/interrupts

Written in December 2023, before 2.0 shipped. The post also introduces the "Destination full" interrupt condition, made for sending a train to a depot.

Cited by: Factorio

An interrupt can name a wildcard signal (any item, any fluid, any fuel, any signal): the train tests the conditions against each item it carries, and the first that passes replaces the wildcard in the target stop's name and wait conditions, so one interrupt sends any cargo to the stop named for it. factorio-logistics/generic-interrupts

Since 2.0 a train told to go to a stop that doesn't exist reports "No path" instead of skipping it, and a disabled stop acts as if its train limit were 0: a train already on its way still arrives, and one sent there waits as "Destination full". factorio-logistics/missing-and-disabled-stops

About: Factorio Rail transport

In 1.1 a missing or disabled stop was skipped.

A train stop has a priority from 0 to 255, 50 by default and settable by circuit: trains choosing a destination prefer the higher priority, and trains at higher-priority stops leave first. A train the player sends somewhere by hand, or one stuck on the main line with no path or a full destination, gets 255. factorio-logistics/stop-priority

2.0 added a selector combinator, which picks signals out of its input: the signal at a given rank when sorted by value, the count of input signals, a random input signal at a set interval, or an item's stack size. 2.1 added a time mode that outputs the game tick, the time of day and the length of a day, and lets the index mode select the N highest or lowest signals. factorio-logistics/selector-combinator

Spawners, not factories, turn pollution into attacks: each update a spawner absorbs 20 plus 1% of its chunk's pollution (the wiki gives two versions of when it stops or what it takes instead, below), and after absorbing a certain amount it sends one of its units to a gathering point; the gathered group attacks after 1 to 10 minutes. The absorbed pollution pays for sending units, not for spawning them. factorio-logistics/pollution-attacks

About: Factorio Enemy spawning

The wiki's two versions disagree: its spread section says a spawner in a chunk with 20 or less absorbs three times its dearest unit's cost instead, while its spawner section says it keeps absorbing 20 + 1% until it holds more than three times that cost. The values are in spawner-pollution-values; the wiki times an update at 64 ticks.

The comment above medium-biter says its weight starts rising at 0.3, but the point it describes is {0.2, 0.0}: the comment is stale, and the data rules. The weights are normalised per spawner, so the medium biter's share at a given evolution depends on the other entries' weights there.

The three sources add into a total that is squashed into the range 0 to 1 as total / (1 + total), so each gain is cut by (1 − evolution)² and evolution never reaches 1.

By this rule, 0.002 for a spawner is the full gain at evolution 0 and a quarter of it (0.0005) at 0.5, the wiki's own example. Since 2.0 evolution is kept per surface, so this is Nauvis's in the base game.

Enemies expand: between 10 and 60 minutes apart, shorter as evolution rises (60 minutes at evolution 0, 10 at 1, on the curve −e² + 2e), a group of 5 to 10 units times 8 to the power of evolution (so 40 to 80 at evolution 1, at the default enemy base settings; 2.1 also scales it with the map's base-size setting) sets out to a chunk 3 to 5 chunks out from the enemy bases already there, where its members turn into new spawners and worms, one every 30 seconds. factorio-logistics/expansion

2.1 reworked the expansion planner (FFF 445): groups scale with evolution and with the map's base-size setting, and candidate chunks favour open or cleared land over thickening infested areas.

Tier 2 for the 50-a-second figure, which rests on the API's meaning of cooldown; the values alone are T3. Physical damage research and enemy resistances (a flat cut, then a percentage) change what lands.

A laser turret has 1000 health and a 24-tile range and needs no ammunition: each shot, every 40 ticks (1.5 a second), costs 800 kJ from its 801 kJ buffer, so it draws 1.2 MW while firing and 24 kW idle. Each hit of its beam does 10 laser damage, doubled by the turret's damage modifier, and one beam can hit more than once: it lasts 40 ticks with a damage interval of 20. factorio-logistics/laser-turret

How many times a 40-tick beam with a 20-tick damage interval hits, and so the turret's damage per second, depends on engine rules we haven't read; it isn't stated here. Tier 2 for the shot rate and power draw, which rest on the API's meaning of cooldown.

The character has 250 health and a healing_per_tick of 0.15; it carries 80 inventory slots, builds and reaches entities up to 10 tiles away, mines resources within 2.7 tiles, picks up items within 1 tile and loot within 2, and hand-mines at speed 0.5. factorio-logistics/character

The data also sets running_speed 0.15 and ticks_to_stay_in_combat 600 (10 s); the API page doesn't describe either, so the running speed in tiles a second isn't stated, and whether the 600-tick combat timer pauses healing (and so what the character regains per second in practice) is unknown. Research and armour add inventory and health; this is the bare character.

Which resources count as basic-solid, and which also need a fluid (uranium ore needs sulfuric acid, resources.lua L166), is in resources.lua, outside this claim. How the crafting queue orders and crafts intermediates isn't in the data; that is a gap for this set.

A ghost marks where an entity or tile is to be built and does nothing else until it is. Placing a blueprint lays down a ghost for everything in it; once construction robotics is researched, a destroyed building leaves a ghost too (trains excepted). factorio-logistics/ghosts

About: Factorio Structure placement

Cited by: Factorio

Construction robots build a ghost when its materials are in the logistic network and robots are free, or, for a player wearing a personal roboport and carrying construction robots, when the player has the materials. A ghost the player placed lasts for ever; one left by a destroyed building lasts a week of game time. factorio-logistics/ghost-construction

About: Factorio Construction

Each robot carries one item at base (robot-speed), so a ghost costs one trip per item it needs, plus the construction area's limit (roboport).
