Artillery wagon

Lachlan: /* Limitations */

{{Languages}}{{:Infobox:Artillery wagon}}
The '''artillery wagon''' is an end-game wagon added in game version 0.16 mounting a [https://en.wikipedia.org/wiki/Railway_gun rail cannon] that can be added to a train. It fires [[Artillery shell|artillery shells]], relatively slow-moving [[Artillery shell|projectiles]] that explore chunks of terrain they travel across. The wagon gun has both automatic and manual (even longer-ranged) firing modes. Projectiles have sufficient damage to destroy spawners and any type of worm with a single hit, and have a modest area of effect. Infinitely-stacking research upgrades are available for range and firing speed, but not damage.

The [[Artillery turret|artillery turret]] is essentially the same weapon, but deployed as a static structure like other turrets.

== Mechanics ==
Artillery wagons have a massive range, outranging fixed fortifications by a factor of 10 or more. In automatic mode, when the train isn't moving, the artillery wagon will automatically scan for enemy structures (spawners and worms) and shoot at them. Automatic mode cannot target mobile units (biters and spitters); shells do, however, damage mobile units in the vicinity of impact normally.

In manual mode, a special [[Artillery targeting remote|item]] is used to point-and-click anywhere in the world, map, or zoomed-in map; each click corresponds to one shell delivered to that location, so long as any working artillery turrets and / or wagons are in range. Targeting remotes show the number of fire-ready (loaded and, for wagons, stationary) artillery pieces in range of cursor position when held. Manual fire can be ordered on unexplored areas; shells will explore all chunks they travel across (but no surrounding chunks).

Range in automatic mode is 224 tiles (7 chunks); in manual mode, 560 tiles (17.5 chunks). Infinite [[Artillery shell range (research)|research]] is available to increase range, at +30% of base range per level, applied to both automatic and manual range.

== Limitations ==
Aside from the considerable expense of research and assembly for both wagons and shells, there are certain considerations that make these wagons unwise as a full replacement for traditional base defenses, despite their phenomenal range and the advantage of mobility.

Artillery shelling will antagonize enemy mobile units in the vicinity of the impact into rushing the wagon's location at time of firing, regardless of their normal "aggro radius". Artillery wagons are relatively slow-firing, although infinite [[Artillery shell shooting speed (research)|research]] is available to improve firing speed, at +100% per level, affecting both wagons and stationary turrets and applying to both automatic and manual mode. They also cannot target mobile units in automatic mode. Importantly, artillery has a ''minimum'' range as well, which is 32 tiles.

Together, these limitations mean that an artillery wagon needs to be defended, or else moved around rapidly, in the latter case decreasing its value as base defense. For defense, any conventional approach such as walls, gun, laser, and / or flamethrower turrets, or the personal intervention of the player will do. However, players should keep in mind that extensive shelling of large biter-infested areas will produce massive attack waves centered on the position of the artillery piece at time of firing, and should plan close-range defenses accordingly.

Logistic considerations are also important, as artillery shells have a stack size of 1, meaning any-size container can only hold a modest supply and an inserter will only ever move a single shell at a time. Players may wish to consider assembling near artillery wagon stops if practical. The wagon itself can hold a supply of 100 shells (while artillery turrets only hold 15), providing a portable magazine of some size that can be towed around with the weapon without external storage.

== Train Properties ==
The artillery wagon can fire while stopped at a train stop, but '''not''' when stopped at a red signal or when moving. When a train with an artillery wagon is stopped at a train stop, aiming and shooting counts as activity for the purposes of "X seconds of inactivity" departure conditions in the train's schedule.

Artillery wagons weigh as much as 4 [[Cargo wagon|regular wagons]] (or 2 [[Locomotive|locomotives]]) for the purposes of train acceleration calculations. Fortunately, the new [[nuclear fuel]] also introduced in version 0.16 provides a massive 250% boost to acceleration (compared to 180% for rocket fuel, the next best type), making it an attractive fuel for artillery trains.

== Trivia ==
[https://en.wikipedia.org/wiki/Railway_gun Large rail-transported cannon] were built in the late 19th and early 20th century, up until and including World War II. The larger models were heavy and very slow firing and took many hours to set up, but had a greater range and power per shot than any other weapon in existence at the time (considerably greater than battleship-size naval guns, for example). The advent of rocketry, as well as large bomber planes capable of deploying multi-ton bombs, eventually made these guns obsolete.
* Perhaps the best-known examples were the [https://en.wikipedia.org/wiki/Big_Bertha_(howitzer) ''Dicke Bertha''] (Big Bertha, literally "Fat Bertha") and the [https://en.wikipedia.org/wiki/Schwerer_Gustav ''Schwerer Gustav''] (Heavy Gustav), the largest gun ever fired.

Artillery targeting remote

2017-12-15T08:54:17Z

Lachlan:

{{Languages}}{{:Infobox:Artillery targeting remote}}{{Stub}}
'''Artillery targeting remote'''s are used to manually destignate targets for the [[artillery wagon]] and [[artillery turret]] by clicking somewhere with them either from the map or normally from the world. They expire when an artillery wagon shoots the spot they designate as a target or after 1 minute. Clicking somewhere with an artillery targeting remote does not use the item up. The number next to the remote when it is held in hand indicates how many artillery wagons or turrets are in range and contain ammunition.

Fluid wagon

2017-12-14T23:10:52Z

Lachlan:

{{Languages}}
{{:Infobox:Fluid wagon}}

The '''fluid wagon''', also known as the '''rail tanker''', is capable of transporting [[liquids]] by [[rail]]. Fluids can be pumped in and out of the wagon using a [[pump]].
Similar to [[cargo wagon]]s, a [[locomotive]] is required to move the liquid wagon.

The fluid wagon consists of three tanks which by default are connected as a single unit to hold a total of 75,000 units of fluid. These tanks can be disconnected from each other to form three separate tanks holding 25k units of fluid each. This way, one fluid wagon can transport three separate fluids without mixing them together. One pump can attach to each of the three tanks.

The fluid wagon weighs three times as much as a regular cargo wagon and will need more locomotives pulling it to move at a similar speed/acceleration to non-fluid trains. It also holds less fluid; a cargo wagon filled with barrels can carry 100,000 units of fluid.

== Troubleshooting ==
To get fluid into the fluid wagon, you need a [[Railway#Stations|train station]] with pumps.

The wagon needs to be aligned with the rail grid; do this by using the [[Automated rail transportation (research)|automated rail transportation]] [[train stop]]s as [[Railway#Train_schedule|train schedule]] destination, and a fueled locomotive.

Also make sure that the [[rail]]s under the Fluid wagon are '''straight rails''' and not '''curved rails'''. The pumps will only work if the wagon is perfectly orthogonal to the grid.

Storage tank

Lachlan: /* Usage */

{{Languages}}
{{:Infobox:Storage tank}}
[[File:storagetank.png|thumb|150px|Four storage tanks linked together to form a large storage facility.]]
The '''storage tank''' is a building that can store up to 25,000 units of a fluid. It is a passive storage - it has no input and no output, depending on pressure to fill it, essentially being a large pipe.

== Usage ==

Storage tanks will only be filled to the same percentage of capacity as pipes that lead to it. Pipe that always carries about 50 water will fill the tank to about 50% of its capacity. [[Pump]]s can be used to fill the entire tank from a low pressure source (such as distant [[pumpjack]]s).

The storage tank is typically used to store excess oils to ensure that [[oil refinery]] works smoothly.

Storage tanks can also be used as a water-based [[accumulator]]s. If steam consumption by [[steam engine]]s changes a lot during the day-night cycle (for example because of [[solar panel]]s or [[laser turret]]s), storage tanks can be filled with steam during low power usage and then emptied during night.

The storage tank can be emptied by ''mining and rebuilding it'' (the fluid is destroyed) or by draining it with a [[pump]].

== Usage as "Energy-Tank" ==

A storage tank filled with [[heat exchanger]] 500°C steam stores around 2.4GJ; a storage tank filled with [[boiler]] 165°C steam stores 750MJ.

* 1 '''Storage tank''' can store 25,000 units of 500ºC steam.

* 1 [[Steam turbine]] can output 5,820kW = 5,820kJ/s using 60 units of 500ºC steam/s.
* 1 Storage tank can keep 1 steam turbine working for 25,000 ∕ 60 ≈ 416.6667s
* A Storage tank can store up to 25,000 ∕ 60 × 5,820 = '''2,425,000kJ''' using 500ºC steam.

* 1 '''Storage tank''' can store 25,000 units of 165ºC steam.

* 1 [[Steam engine]] can output 900kW = 900kJ/s using 30 units of 165ºC steam/s.
* 1 Storage tank can keep 1 steam engine working for 25,000 ∕ 30 ≈ 833.3333s
* A Storage tank can store up to 25,000 ∕ 30 × 900 = '''750,000kJ''' using 165ºC steam.

Solid fuel

Lachlan: /* When to use Solid Fuel as fuel */ rewording

{{languages}}
{{:Infobox:Solid fuel}}
'''Solid Fuel''' is the third kind of [[Fuel]] besides wood and coal and is processed in a [[Chemical plant]].

Besides being useful as fuel in all [[Burner devices]], Solid Fuel is also used to produce [[Rocket fuel]], which is a component of [[Rocket part]]s built in the [[Rocket Silo]].

== Recipes ==

Solid Fuel can be created from [[Heavy Oil]], [[Light Oil]] or [[Petroleum Gas]].

== When to use Solid Fuel as fuel ==

Coal and Solid Fuel production can both be automated, but each has advantages and disadvantages. Solid Fuel is made from oil, and oil supplies are theoretically infinite, since oil spots never run completely dry. However, coal is almost always used first, and if coal is plentiful on the map, it may not be worth it to switch systems over to an oil infrastructure just for fuel.

0.15 has changed all this, since now Solid Fuel gives vehicles greater acceleration and top speed. Also [[Coal liquefaction (research)|Coal liquefaction]] is now available, giving the ability to turn coal into oil.

One unit of Solid Fuel contains 25MJ of energy, over three times the energy value of coal.

== Which Solid Fuel recipe to use ==
* [[Light Oil]] has the best oil to Solid Fuel ratio (10:1), and has little other in-game use, making it the best choice.
* [[Heavy Oil]] has a much worse ratio (20:1) and should be cracked into Light Oil first instead. The cracking process changes the ratio for Heavy Oil to 13:1, which is much better.
* [[Petroleum Gas]] also has a bad 20:1 ratio and should not be used to create solid fuel in most cases.

However, full tanks of Heavy Oil, Light Oil, or Petroleum Gas can back up and block the Oil Refinery from refining more Crude Oil. This can create a situation where, for example, you can't create Petroleum Gas because your Heavy Oil tanks are full. It's advisable to set up some Solid Fuel factories to relieve the pressure in cases like this, particularly once [[Circuit network]]s have been researched and the factories can be switched on automatically once liquid levels reach a certain amount.
