'''ベルト輸送システム(Belt transport system)'''は、アイテムを異なる場所の間で輸送するために[[player/ja|プレイヤー]]が最初に触れることとなるシステム。[[Railway/ja|列車]]、[[Logistic network/ja|物流ロボット]]と並んで、Factorioにおけるアイテム輸送システムを構成している。
3種類の階級のベルトが使える。[[transport belt/ja|搬送ベルト]]は黄色くて一番遅いが、同時に一番製造コストが安い。次の階級は赤い[[fast transport belt/ja|高速搬送ベルト]]で、通常の2倍速。[[express transport belt/ja|超高速搬送ベルト]]は最も階級が高く、青色で通常の3倍、もしくは赤ベルトの1.5倍。
A deadlock or gridlock can happen when every train is locked by another. In nearly every case two or more trains are standing so that every train blocks (by minimum) one other train.
=== Deadlock occurrence ===
Deadlocks occur when two or more trains are prevented from continuing through an intersection, due to an unsolvable signal conflict. There are a few different types of deadlocks:
# Temporary - These are caused by a temporary hiccup in a train's path, such as a loading train being in the way, or created by closing a signal with the [[circuit network/ja|circuit network/ja]]. These often resolve themselves.
# Semi-permanent - These are the result of a problem with pathing, often created by a fuel-less train or broken rail, and may require player interaction to resolve, or (in the case of broken rails) may be corrected automatically by construction robots.
# Permanent - This type is the worst, and cannot be resolved automatically, often requiring the player to manually drive several trains to get them out of the intersection. These often are caused by incorrect signal placement or unreachable stations.
It's important to remember that deadlocks can happen by chance, and by mistake of the player. Sometimes even perfectly signaled rails have issues. The rate of deadlocks is inversely proportional to the quality of signaling, however.
=== Factors that influence the deadlock chance ===
* Train length (shorter trains will have a lower chance with the same rail/signal layout, due to having less effect on the rails they're on.)
* Size of the blocks: More space for the blocks means lower chance of deadlock.
* Track layout: Some layouts have a higher chance of locking than others.
* Quantity of trains - More trains trying to use an intersection will result in higher chance of deadlock.
* The chance is also much higher if trains need to wait often in areas with rail-crossings.
Knowing the factors, how can deadlocks be reduced?
* Don't use 4-way junctions or roundabouts (circles) to create junctions.
* Use better 3-way junctions. See [http://www.factorioforums.com/forum/viewtopic.php?f=18&t=9044 A Detailed Look at a Bidirectional Three-way Train Intersection]
* Use roundabouts only for changing direction of train, and never for high traffic intersections.
* Build more tracks around junctions. Don't have one junction be the only way to reach a place, add redundancy. This keeps a small problem a small problem.
== Automated transport ==
[[File:train-schedule-gui.png|thumb|300px|The scheduale tab in the train GUI: 1 - switch between automatic and manual driving mode; 2 - add new train station; 3 - delete selected station; 4 - send train to selected station; 5 - add wait condition for selected station; 6 - delete selected wait condition; 7 - change logical mode of selected wait condition/ja|]]
Trains set on "Automatic" choose their destination stop and route on departure, and after waiting at a chain signal for five seconds, and when their destination stop disables itself by circuit condition. They choose the shortest route using a [[Railway/Train_path_finding|path finding algorithm/ja|]] that will get them to an enabled train stop with the right name, taking penalties for any apparent-at-the-time delays into account. If no such train stop exists they will skip the stop and go on to the next.
=== ベルトの合流・分岐 ===
This section covers items used to make trains automatically transport items between stations. The player should be familiar with creating a rail system.
First, the player has to setup a rail system with at least two train stops, which are placed in the right-hand side of the expected train arrival direction. By hovering over the train stop with the mouse you see the positions of the vehicles for better setting up the train station (including (un)loading machinery, refueling/repair installations).
When you set up the train schedule (see below) and fuel the train, you can start the train on it's schedule by switching from manual to automatic driving mode.
The player can set up a list of train stations in the upper window. The train will route to stops in the given order, if it's at the end it will continue with the first. Currently, it's not possible to make a one-time schedule. Stations can be added by clicking button 2 (see picture). A pop-up appears with a list of all stop names. If you select one, another pop-up appears for you to select a wait condition.
Wait conditions are used to tell the train when to leave the station. There are 7 types of wait conditions:
* '''Inventory full''' - All inventories of the train are full.
* '''Inventory empty''' - Same as above, but empty.
* '''Item count''' - The train (all cargoes summed) contains a specific amount of a certain item.
* '''Circuit condition''' - The train stop is connectable to the [[Circuit network/ja|Circuit network/ja]], so the signals can used for wait conditions.
* '''Inactivity''' - No items were added or removed for the specified amount of seconds.
* '''Fluid count''' - The train (all fluid wagons summed) contains a specific amount of a certain fluid.
Hereafter the word "term" is used to describe ''one'' type of wait condition, and the words "wait condition" are used to describe the whole set of terms (it turns a bit into maths).
If you add more than one term, you can change the connection of those using the logical operators AND and OR (button 7). An AND condition will result in true if all terms are true. An OR condition will return true if at least one of the terms is true.
=== ベルトスループット ===
[[File:Stack inserters fill express belt.gif|frame|right|[[stack inserter/ja|スタックインサータ]]4つで超高速ベルトを満載できる。左の2つはスタックサイズ12、右の2つはスタックサイズ7。]]
スループットの最大化は、ベルトを効率化するために重要である。そのため、いくつかの定義を導入しよう。
When mixing AND and OR terms, the logic is grouped by the OR terms. When evaluating the wait condition, the first term is evaluated along with all AND terms immediately following up to but excluding the next occurring OR term. If they all evaluate true, the wait condition evaluates true. Otherwise, evaluation continues with that next occurring OR term and all AND terms immediately following it, up to the next OR term. This continues until either an OR group evaluates true and the wait condition is satisfied, or all terms have been checked.
Factorio's wait condition logic is read as disjunctive normal form ([https://en.wikipedia.org/wiki/Disjunctive_normal_form DNF]), and so this last example is processed as (note the parenthesis):
=== 機構 ===
<pre>((Cargo: Iron ore < 500 AND 30 seconds passed) OR (Cargo: Copper ore < 500 AND 30 seconds passed))</pre>
* Another train on the same [[Railway#Segment|segment/ja|]] or [[Railway#Block|block/ja|]]? Make sure the path of the train is unobstructed.
* Train stops placed correctly? Make sure that the yellow arrows when hovering on the stop point towards the end or exit of the stop.
* Is the train allowed to enter signals from the right direction? Are the signals set correctly?
* If a track is supposed to be two-way, the rail signals should be opposite each other. You can verify they match up by hovering the cursor over one. For a matched pair, it will show the other.
==== No path ====
=== バランシング ===
When trains cannot reach the target, a "no path" symbol pops up over the locomotive. Check:
* Can the train reach its current destination by '''only driving forward'''? Build turning slopes or place a locomotive at both ends of a train!
* Are the train stops standing in the right direction? Train stops must be on the right hand side of the track.
* If you use rail signals, check that the signals are all allowing traffic in the correct direction.
* Check for interruptions in the train tracks, drive to the station manually to check there are no rail parts missing. Especially near junctions these can be hard to spot if missing.
If you are still having problems, consider:
{{Main|Balancer mechanics/ja|l1=バランシング機構}}
* Driving the train manually, and as you pass each switch, try switching to automatic. When it works, you will know the rough area of the problem.

ベルト輸送システム(Belt transport system)は、アイテムを異なる場所の間で輸送するためにプレイヤーが最初に触れることとなるシステム。列車、物流ロボットと並んで、Factorioにおけるアイテム輸送システムを構成している。
(訳注:0.16現在、"transport"は搬送ベルトについてのみ「搬送」と訳され、それ以外に於いては「輸送」と訳されている。以下では固有名詞以外は「輸送」に統一する)
Underground belts can be used to cross different flows of items without interfering. They move items like a 通常のベルト.
Underground belts can cross any number of entities and all types of ground, like water and grass. (as long as the input and output endpoints are on land)
Underground belts can cross other underground entities (any number of underground belts or underground pipes). They won't be mixed.
For the connection only the endpoints (entry-side and exit-side) are relevant.
An underground belt pair of that bridges a gap of 4 tiles stores up to 44 items. An express underground belt pair at max length stores up to 72 items.
The half of the underground belt tile with a belt can accept input from the side. The other half (with a tunnel entrance) blocks incoming items.
ベルトレーン分岐
This is built by placing one underground belt and then using R to reverse its direction. This converts the underground belt entrance to an exit (and vice versa).
This can also be used to split the lanes of a belt onto seperate belts instead of using a splitter filter.
