{"category":"content","changelog":"---------------------------------------------------------------------------------------------------\nVersion: 2.8.0\nDate: 2026-05-28\n  Changes:\n  Bugfixes:\n    - When a train contains an item with a quality other than normal arrives at a provider that supplies the\n      same item in quality normal, the output got confused and sent out the wrong signal. Reported by @Odhrean in #47\n  Minor Features:\n    - Support locomotive types that do not need refueling. Expose a new remote API where such mods can register with LTN\n      to have their locomotives excluded from refueling.\n---------------------------------------------------------------------------------------------------\nVersion: 2.7.1\nDate: 2026-05-24\n  Changes:\n    - When removing a mod that provides surface connections, clean up existing connection references\n      in deliveries, otherwise on_dispatcher_updated will not fire until all invalid entities have\n      disappeared\n  Bugfixes:\n    - Ensure that no duplicate surface connections are listed when sending dispatcher updates\n    - When trains switch surfaces often, the train_selected count could have gotten lost\n    - If an entity representing a surface connection gets invalidated, the on_dispatcher_updated event\n      may have been silently discarded.\n  Minor Features:\n    - Add clarification and documentation for other mods that use cross-surface connections with LTN.\n      Makes [LTN - Space Exploration Integration](https://mods.factorio.com/mod/ltn-space-exploration) work well.\n---------------------------------------------------------------------------------------------------\nVersion: 2.7.0\nDate: 2026-05-12\n  Bugfixes:\n    - Fixed crash bugs, reported by @kratons123 (#32), @smittythesmith (#34), @afatsum72 (#36),\n      @Giuzu (#40), @tundy (#43, #57), @xyzzycgn (#52), @ArhangeL1790 (#55), @theojk2 (#56), @CoreNest (#58)\n      and many more.\n    - Fix support for double-ended trains (and single endeded stations). Reported by @lamhoangsudo and @Que914\n      on the forums\n  Changes:\n    - Make all .log and .printmsg statements lazy; this should help a bit with FPS.\n  Minor Features:\n    - new startup setting to control Train Limit for depot stations\n---------------------------------------------------------------------------------------------------\nVersion: 2.6.0\nDate: 2025-12-17\n  Changes:\n    - Implement a fairer train selection algorithm that does not select by path length. This\n      is controlled by the `ltn-depot-fudge-factor` setting. If the setting is 0, the old, distance-based\n      algorithm is still used.\n    - Use train_manager to compute travel distance between stations, replace the simple 'shortest path as the crow flies' algorithm\n---------------------------------------------------------------------------------------------------\nVersion: 2.5.1\nDate: 2025-11-24\n  Bugfixes:\n    - fix crash bug when comparing surfaces (reported by many people on the Forum)\n---------------------------------------------------------------------------------------------------\nVersion: 2.5.0\nDate: 2025-11-20\n  Minor Features:\n    - add new event, `on_delivery_reassigned`; gets raised when a delivery moves from one train to another.\n    - add new setting, `Advanced Cross-Surface Delivery` to control deliveries in multi-surface networks.\n  Changes:\n    - when a refuel station has no fuel signals, turn its lamp gray, not cyan\n    - when enabling detailed messages, report if a station uses the default network id (not receiving a\n      network id signal)\n    - remove train limit from LTN stops and remove any signal to change train limits\n    - upper limit for refuel interrupt now uses <=, this allows setting '1' as a value.\n  Bugfixes:\n    - fix crash with fuel station not having fuel signals right after construction\n---------------------------------------------------------------------------------------------------\nVersion: 2.4.3\nDate: 2025-11-17\n  Bugfixes:\n    - remove fuel station and depot status when a stop changes from a depot/fuel station to something else\n---------------------------------------------------------------------------------------------------\nVersion: 2.4.2\nDate: 2025-09-28\n  Changes:\n    - debug logging is now controlled by an int setting to provide different levels of logging.\n  Bugfixes:\n    - fix crash when another mod adds a temporary refueling record at the beginning of the schedule\n    - make sure that any freshly minted train that gets sent to a depot for the first time really gets\n      the wait condition for the depot. Reported by @mikegarrison on the forums\n---------------------------------------------------------------------------------------------------\nVersion: 2.4.1\nDate: 2025-09-27\n  Bugfixes:\n    - fix a crash when using a depot or fuel station that is not connected to a rail (reported by @YenzRahbek on the forum)\n    - fix a crash when reading schedule conditions does not contain a constant (reported by @Generalisator on the forum)\n  Changes:\n    - setting 'ltn-depot-fluid-cleaning' to -1 will always clean all fluids from the train\n---------------------------------------------------------------------------------------------------\nVersion: 2.4.0\nDate: 2025-09-26\n  Changes:\n    - When updating the schedule, try to keep the depot stop valid all the time\n    - Add setting to choose between refueling with an interrupt or dynamic (LTN controlled) refueling\n    - Implement dynamic refueling (controlled by LTN)\n    - Default for 'ltn-provider-ignore-stopped-train' setting is changed from `true` to `false` (Issue #26, reported by @Quetzler on github)\n  Bugfixes:\n    - When a station changes status (depot -> fuel stop or regular stop, fuel stop -> depot etc.),\n      ensure that all status bits are correctly updated. Fixes #28, reported by @Spacey42 on the forum)\n---------------------------------------------------------------------------------------------------\nVersion: 2.3.4\nDate: 2025-06-23\n  Changes:\n    - restore the behavior that the virtual signals for the lamp color are only present on the green wire. Add documentation.\n    - allow negative amount of fuel for refuel station (treat it as positive). Allows using the LTN combinator to provide fuel amounts.\n  Bugfixes:\n    - fuel station lamp switched to blue when train parked, then back to cyan when train leaves\n---------------------------------------------------------------------------------------------------\nVersion: 2.3.3\nDate: 2025-05-09\n  Bugfixes:\n    - fix broken GetNextLogisticStop function (Reported by @harag-on-stream on Github, PR #18. Thank you!)\n    - when a train is put under LTN control, it is removed from a train group first (Suggested by @wchristian on Github, #17. Thank you!)\n  Changes:\n---------------------------------------------------------------------------------------------------\nVersion: 2.3.2\nDate: 2025-03-21\n  Changes:\n    - Make schedule parsing more robust after someone managed to trigger the `assert(record.provider ~= record.requester)` assert. Reported by @labminto on the mod forum.\n---------------------------------------------------------------------------------------------------\nVersion: 2.3.1\nDate: 2025-03-20\n  Bugfixes:\n    - Fix the prototype meld statements\n    - Explicitly initialize the storage depot array. Fixes #14, reported by @ITZtephen on github\n---------------------------------------------------------------------------------------------------\nVersion: 2.3.0\nDate: 2025-03-11\n  Changes:\n    - refactor schedule management with new LuaSchedule API\n    - add new station type 'fuel station'\n    - add new virtual signal 'ltn-fuel-station' to declare a stop to be a fuel station\n    - add configuration option 'ltn-schedule-fuel-station' to enable/disable fuel station support\n    - add configuration option 'ltn-schedule-reset-interrupts' to enable/disable schedule reset\n    - add configuration option 'ltn-schedule-reselect-depot' to enable depot changes within a network\n    - [API] add attribute `is_fuel_station` to `ltn.TrainStop` to show whether this is a fuel station\n    - [API] add attribute `fuel_signals` to `ltn.TrainStop` for the fuel conditions added to the refuel interrupt\n    - trains will reselect a depot in their network when leaving requester and 'delivery ends at requester' is active\n    - Hide LTN internal entities (stop lamp + combinators) from Factoriopedia\n---------------------------------------------------------------------------------------------------\nVersion: 2.2.1\nDate: 2025-02-27\n  Bugfixes:\n    - fix crash when renaming a non-LTN entity (e.g. a spidertron). Reported in the mod forum by @Nekrobot, thank you!\n  Changes:\n---------------------------------------------------------------------------------------------------\nVersion: 2.2.0\nDate: 2025-02-26\n  Bugfixes:\n    - fix typo in dispatcher that caused crashes when recomputing shipmends because of too many stacks\n  Changes:\n    - Changed default network value from -1 (\"all networks\") to 0 (\"no networks\"). This affects any station\n      that has no explicit network id signal connected. Rationale for that change is that before this release,\n      turning off a connected combinator (LTN or constant combinator) will activate the station for all\n      networks instead of turning it off. If your setup relies on the default signal being \"-1\", set it\n      explicitly in the LTN settings.\n    - Add a new setting \"Requesters ignore stopped trains\" that allows ignoring unloading trains when scheduling\n      new requests\n---------------------------------------------------------------------------------------------------\nVersion: 2.1.2\nDate: 2025-02-25\n  Changes:\n    - enforce that only items can be put into a merged delivery (Same as #9 by @abrenneke, thanks for the PR!)\n---------------------------------------------------------------------------------------------------\nVersion: 2.1.1\nDate: 2025-02-23\n  Changes:\n    - support quality for cargo/fluid wagons (they might have larger inventories).\n    - harden the signal processing to only allow item/fluid signals.\n---------------------------------------------------------------------------------------------------\nVersion: 2.1.0\nDate: 2025-02-12\n  Changes:\n    - support item quality for requesters and providers.\n---------------------------------------------------------------------------------------------------\nVersion: 2.0.3\nDate: 2025-02-06\n  Bugfixes:\n    - Fix \"unscheduled cargo\" messages even if everything is ok.

Logistic Train Network\r\n\r\nFactorio mod adding \"logistic-train-stops\" acting as anchor points for building a train powered logistic network.\r\n\r\nIt can handle multiple train configurations and will pick the best available train for a delivery.\r\n\r\n## FAQs\r\n\r\n### I get error messages: \"No station supplying ... found in networks 0x0\"\r\n\r\nLTN uses \"Network Id\" to allow creating multiple networks that can act separately. A lot of examples assume that there is only one network (\"the LTN network\"). When using only a single network, all stations have the same network id. The network id is provided either through a signal sent into the Station Lamp *OR* as a default setting in LTN. Many \"getting started\" examples assume that the stations get their station id from that default setting.\r\n\r\nUp until 2.2.0, the default network id was \"-1\" (which actually translates to \"all LTN networks\"). This is fine, as long as there is only one network.\r\n\r\nFor more elaborate setups with multiple networks, this default value caused a problem: Any station that is built and that does not get an explicit network signal (e.g. through a LTN Combinator) will show up in \"all LTN networks\". This especially happens when the LTN combinator is fully configured but then turned *off*. So trains from all the networks will show up at the station because there was a signal *missing*. This was hard to reason about and hard to debug.\r\n\r\nFor that reason, the \"default network id\" was changed in release 2.2.0 from \"-1\" to \"0\". This means, that a newly built LTN train stop will not be part of *any* network unless there is an explicit network id signal sent into the station. *OR* the default network id is set by the player.\r\n\r\nIf you run a relatively simple setup (only a single LTN network) and do not have you stations provide an explicit network id, you will encounter the `No station supplying ... found in networks 0x0` error message. In that case, go to `Settings -> Mod Settings -> Map -> LTN - Logistic Train Network -> \"Default network ID\"` and change the default value from \"0\" to e.g. \"1\". You can also use the old default (\"-1\").\r\n\r\nIf all your stations have an explicit network id provided (e.g. through LTN Combinators), the default of \"0\" is correct and will avoid that new stations mess up your train schedule.\r\n\r\n### What is 'Advanced Cross-Surface Delivery'?\r\n\r\nIf you are not using a mod like [Space Exploration](https://mods.factorio.com/mod/space-exploration) and the [LTN - Space Exploration](https://mods.factorio.com/mod/ltn-space-exploration) mod, this setting is not for you and you should simply leave it off.\r\n\r\nThis setting is for games where the train network stretches across multiple surfaces *that are connected*. This is not true if you e.g. use the same network id on two planets (e.g. Gleba and Nauvis) that are not connected.\r\n\r\nIf you have a network across multiple surfaces, then normally a train can be dispatched to a provider on the same surface as the depot, go through the space elevator into orbit and deliver to a requester on a different surface, then return back to the depot on the original surface. LTN will not schedule anything else, the provider *must* be on the same surface as the depot.\r\n\r\nWith this setting, LTN will schedule trains to go through the space elevator first if necessary to pick up a delivery from a different surface. It may even schedule a delivery where both provider and requester are on a different surface as the depot. The train will still return to its original depot.\r\n\r\n[LTN - Space Exploration](https://mods.factorio.com/mod/ltn-space-exploration) fully supports this.\r\n\r\nIf you are using [Space Exploration LTN integration](https://mods.factorio.com/mod/se-ltn-glue), you need to verify that it was updated to support advanced scheduling, otherwise your trains will stall with \"No path found\".\r\n\r\n\r\n## Factorio 2.0 Updates\r\n\r\nLTN has been ported to Factorio 2.0. It will get minimal updates (only really glaring bugs). The current plan is to provide a successor that takes advantage of the improved 2.0 trains while maintaining the ease of scheduling and dispatching with LTN.\r\n\r\n### Train Schedule Interrupts (since 2.3.0)\r\n\r\nFactorio 2.0 trains support \"Train Schedule Interrupts\" which trigger under certain conditions. Starting with 2.3.0, LTN will not change any interrupts in the train schedule unless explicitly configured with the `ltn-schedule-reset-interrupts` setting.\r\n\r\n### Refueling support (since 2.3.0)\r\n\r\nStarting with 2.3.0, LTN supports a new station type: 'Fuel Station'. Fuel station support must be explicitly enabled by setting the `ltn-schedule-fuel-station` setting.\r\n\r\nSimilar to a depot, there is a virtual signal that declares a stop to be a fuel station. This stop needs to receive additional signals:\r\n\r\n- A network id signal that describes for which networks this fuel station is valid. Use `-1` for all networks.\r\n- Fuel signals ('coal', 'wood', 'solid fuel', 'rocket fuel', 'nuclear fuel' in the base game) with a value that is used as the threshold for refueling. A fuel station does not need to send only the signals for fuels that it provides; the signals are used to create the condition for the fuel interrupt.\r\n\r\nE.g. a station that receives 'wood' = 250 and 'rocket-fuel' = 200 for network id 1 will create a refuel interrupt for all locomotives in the network 1 that will send any locomotive to this refuel stop if they use either wood or rocket fuel and the count drops under 250 for wood or 200 for rocket fuel.\r\n\r\nIf a station receives both the depot and the fuel station signal, it is considered a depot and will not be used as a fuel station.\r\n\r\nA fuel station has a cyan-colored station lamp to signify that it is a fuel station. Starting with 2.5.0, if a fuel station has no actual fuel signal, it will turn its lamp grey.\r\n\r\nTrains arriving at a fuel station will leave if either all locomotives are fully fueled or there are 120 ticks (two seconds) of inactivity. When a train leaves a fuel station, the refuel interrupt is temporarily removed (it gets re-added when the train arrives at a depot that is part of a network that supports refueling).\r\n\r\nLTN refueling is very limited and only looks at the fuel count across all locomotives. By disabling the resetting of Train Schedule interrupts and the builtin refueling support, other mods can be used to control refueling without LTN interfering.\r\n\r\n### Depot changing (since 2.3.0)\r\n\r\nA train that is added to the LTN network will return to a depot when it finishes a delivery. If the 'ltn-schedule-reselect-depot' option is disabled, a train will always return to the depot it was assigned to (the depot that it was sent to when sit registered with the LTN network).\r\n\r\nIf this setting turned on and also 'ltn-dispatcher-requester-delivery-reset' is enabled, then LTN will, as soon as the train leaves the requester, select one of the depots that accepts trains in the current network at random. Trains may go to a different depot in that case. This is especially important if a depot serves multiple networks. A train that gets sent to a depot that serves multiple networks becomes eligible to requests in those networks (assuming that capacity, length etc. also match).\r\n\r\nThis setting has the potential to pile up trains in depots that are too small to accommodate all trains that are sent there. Use with caution.\r\n\r\n### Controlling LTN Stops with the circuit network (or logistics network)\r\n\r\nLTN stops are managed by the central dispatcher and require some settings that will be enforced. Each LTN stop will always have \"Read train contents\" and \"Send to train\" activated, even if no circuit network is connected.\r\n\r\nThe 'Priority' 'Enable/Disable', 'Read stopped train', 'Read train count' and 'Set priority' fields can be manually changed.\r\n\r\n#### Depot stop train limits [Since 2.7.0]\r\n\r\nLTN manages train limits for all stops automatically. For normal operations, it will remove any train limit (and disable setting through the circuit network) as this interferes with the dispatcher. For most stop types (requester, provider and fuel station), this can not be changed.\r\n\r\nThe train limit for depot stops can be modified by changing the startup option 'ltn-depot-stop-limit-trains'. There are three possible values:\r\n\r\n- Reset Train Limit: This is the default. Depot stops behave like all other station types: Any limit is reset and can not be modified\r\n- Set Train Limit to 1: Sets a limit of one train for each depot stop.\r\n- Do not modify Train limit: LTN stops managing the train limit setting for depot stops and it can now managed like the other fields listed above.\r\n\r\n\r\n### API\r\n\r\n[LTN Settings Documentation](https://github.com/hgschmie/factorio-LogisticTrainNetwork/blob/master/SETTINGS.md)\r\n[LTN API Documentation](https://github.com/hgschmie/factorio-LogisticTrainNetwork/blob/master/API.md)\r\n[LTN additional Documentation](https://github.com/hgschmie/factorio-LogisticTrainNetwork/blob/master/MANUAL.md)\r\n\r\nStarting with version 2.1.0, LTN supports quality for requester and provider signals.

logistic-train-stops acting as anchor points for building a fully automated, train logistic network.\r\nIt can handle all possible train configuration. Just send all trains to depots and LTN will pick the best suitable train for a job.\r\nLTN cuts the amount of rolling stock required to run a megabase down to 30% or less.\r\n\r\nWith cargo ships installed also adds a logistic port for ships.","tags":["trains","circuit-network"],"thumbnail":"/assets/0e963b602ac15eb83c7456ea27ac1123fa4b8099.thumb.png","title":"LTN - Logistic Train Network","updated_at":"2026-05-29T04:56:50.351000Z"}
