Editing Steam Locomotive

[[File: Wiki Navy.png|right]]
A [[Steam Locomotive]] is used for mass transit of [[passenger]]s and/or [[cargo]].
* It is a type of [[civilian vehicle]] and a type of [[Railroad Locomotive]].
* It operates on [[train]] networks.
* It is an element of [[infrastructure]].

== Description ([[Specifications]]) ==
Steam locomotives have [[External Combustion|external combustion]] engines: the combustion of [[Ship Fuel|fuel]] within a firebox or burner heats a sealed tank of water, turning it to pressurized steam. This steam powers pistons, which in turn transmit power to the driving wheels through interlocking rods.
* Steam locomotives typically operate on [[Railroad Train|railroad]] networks.
* They are operated using [[Control Panel|mechanical controls]].
* They carry an onboard supply of [[Ship Fuel|fuel]] and [[water]].

Large [[External Combustion|external combustion]] engines (as used in locomotives and maritime vessels where the overall [[power plant|engine]] weight is relatively unimportant) can reach relatively high effective efficiencies. As such they remain an important element of [[infrastructure]] at the end of the [[TL:1-3]] epoch and throughout the [[TL:4-6]] epoch.
* Suitable [[Ship Fuel|fuel]] can be obtained from a variety of sources - its primary characteristic is that it can burn and produce heat. The most commonly used are fossil varieties such as coal, organics such as wood, or refined [[Ship Fuel|hydrocarbons]].
* [[Water]] must be topped up on a regular basis. Allowing the locomotive to run dry can have catastrophic consequences.
