What is Steam locomotive?
[[File:Stephenson 110 Planet, 1832.jpg|thumb|Drawing of an early steam locomotive (about 1830)]] A '''steam locomotive''' is a [[steam engine|steam powered]] [[locomotive|railway locomotive]]. It was used a lot between about [[1830]] and [[1970]]. Afterwards, [[diesel]] and [[electric]] [[locomotive]]s were used more often. The first [[steam]] locomotive was made by [[Richard Trevithick]] for a railway used for moving [[iron]] at an [[Ironworks]] in [[Wales]]. A steam locomotive works by [[burning]] a [[fuel]] like [[coal]] in a special space called a firebox. This produces hot [[gases]] that rise and go through [[tube]]s in a [[boiler]] - a large space with [[water]] in it. This heats the water, producing [[steam]]. The steam is then taken through another tube to a [[cylinder]]. The steam then pushes the piston which in turn pushes a metal rod that is connected to the wheels, making the locomotive move. The steam then rises out through the [[chimney]]. Early in the 19th century, steam locomotives were created in the UK, and they were utilized for railroad transportation until the mid-1900s.Steam locomotives are still today used in many developing countries where the railways have not yet been electrified. == Other websites == {{commonscat|Steam locomotives}} *[http://commons.wikimedia.org/wiki/Category:671 GKB 671:The longest serving steam locomotive in the world (since 1860)] *[http://www.steamlocomotive.com/ Database of surviving steam locomotives in North America] *[http://steamrailroading.com/ Information on North American steam railroads in operation] *[http://www.heritagerailways.com/ UK heritage railways and preserved locomotives database] *[http://www.5at.co.uk/ Pages for the British project to build a modern steam locomotive.
