Editing 4-4-0 (section)

===British development===
The first British locomotives to use this wheel arrangement were the {{RailGauge|7ft0.25in}} [[broad gauge]] 4-4-0 [[tank engine]] designs which appeared from 1849. The first British [[tender (rail)|tender locomotive]] class, although of limited success, was the broad gauge [[GWR Waverley Class|''Waverley'' class]] of the [[Great Western Railway]], designed by [[Daniel Gooch]] and built by [[Robert Stephenson & Company]] in 1855.<ref>{{cite web| url=http://www.laluciole.net/gwr/gwr04a-goochlocos.html| title=A history of Britain's broad gauge railways| author=Richard Marshall| access-date=2010-05-02| archive-url=https://web.archive.org/web/20110723175326/http://www.laluciole.net/gwr/gwr04a-goochlocos.html| archive-date=2011-07-23| url-status=usurped}}</ref>

The first American-style British 4-4-0 tender locomotive on {{RailGauge|4ft8.5in|al=on|allk=on}}, designed by [[William Bouch]] for the [[Stockton & Darlington Railway]] in 1860, followed American practice with two [[Cylinder (locomotive)#Outside cylinders|outside cylinders]].<ref>{{cite web| url=http://www.lner.info/eng/bouch.shtml| title=The London & North Eastern Railway (LNER) Encyclopedia - William Bouch| last=Marsden  |first=Richard| access-date=2007-06-11| archive-url= https://web.archive.org/web/20070707043646/http://www.lner.info/eng/bouch.shtml| archive-date= 7 July 2007 | url-status= live}}</ref>

Britain's major contribution to the development of the 4-4-0 wheel arrangement was the [[Cylinder (locomotive)#Inside cylinders|inside cylinder]] version, which resulted in a steadier locomotive, less prone to oscillation at speed. This type was introduced in Scotland in 1871 by [[Thomas Wheatley (locomotive engineer)|Thomas Wheatley]] of the [[North British Railway]].<ref name="Poultney">{{cite book
