[[Image:Adler May 2008 Fuerth 3.jpg|thumb|Replica of ''Adler'' at Fürth, May 2008]] Under the [[Whyte notation]] for the classification of [[steam locomotive]]s, '''2-2-2''' represents the [[wheel arrangement]] of two [[leading wheel]]s on one axle, two powered [[driving wheel]]s on one axle, and two [[trailing wheel]]s on one axle. The wheel arrangement both provided more stability and enabled a larger [[Firebox (steam engine)|firebox]] than the earlier [[0-2-2]] and [[2-2-0]] types. This configuration was introduced in 1834 on [[Robert Stephenson]]'s '[[Patentee locomotive]]' but it was later popularly named '''Jenny Lind''', after the [[Jenny Lind locomotive]] which in turn was named after the popular singer. They were also sometimes described as '''[[single (locomotive)|Singles]]''', although this name could be used to describe any kind of locomotive with a single pair of driving wheels. ==Equivalent classifications== Other equivalent classifications are: *[[UIC classification]]: '''1A1''' (also known as [[German classification]] and [[Italian classification]]) *[[French classification]]: '''111''' *[[Turkish classification]]: '''13''' *[[Swiss classification]]: '''1/3''' ==History== The 2-2-2 configuration appears to have been developed by [[Robert Stephenson and Company]] in 1834, as an enlargement of their [[2-2-0]] ''Planet'' configuration, offering more stability and a larger [[Firebox (steam engine)|firebox]].

[[File:North Star photograph.jpg|thumb|[[Great Western Railway]] [[North Star (broad gauge locomotive)|North Star]] at Swindon]] ===Later UK developments=== [[Sharp, Roberts and Company]] constructed more than 600 2-2-2 locomotives between 1837 and 1857.

[[John Rennie the Younger|J. & G. Rennie]] supplied 2-2-2 locomotives to the [[London and Croydon Railway]] from 1838 and the [[London and Brighton Railway]] in 1840.<ref>D.L.

B. Longridge and Company]] of [[Bedlington]], Northumberland in 1839. The Great Western Railway continued to order both [[broad gauge]] and [[standard gauge]] locomotives on the railway, including the [[GWR Firefly Class|Firefly]] and [[GWR Sun Class|Sun classes]] (1840–42), which were enlarged versions of [[North Star (broad gauge locomotive)|North Star]]. [[Bury, Curtis, and Kennedy]] supplied six 2-2-2 locomotives to the [[Bristol and Gloucester Railway]] in 1844, and fourteen to the [[Great Southern and Western Railway]] in Ireland in 1848, (the last of these has been preserved at [[Cork Kent railway station]]. [[File:Jenny Lind locomotive.jpg|thumb|left|The original "Jenny Lind" locomotive, 1847.]] The [[Jenny Lind locomotive]], designed by [[David Joy (engineer)|David Joy]] and built in 1847 for the [[London Brighton and South Coast Railway]] by the [[E.B.Wilson and Company]] of [[Leeds]], became the basis of hundreds of similar passenger locomotives built during the 1840s and 1850s by this and other manufacturers for UK railways. The [[London & North Western Railway]] [[LNWR 2-2-2 3020 Cornwall|Cornwall]] locomotive was designed at [[Crewe Works]] as a [[4-2-2]] by [[Francis Trevithick]] in 1847, but was rebuilt as a 2-2-2 in 1858. Although by the 1860s the 2-2-2 configuration was beginning to be superseded by the [[2-4-0]] type with better adhesion, the invention of [[Sandbox (locomotive)|steam sanding]] gave 2-2-2 singles a new lease of life, and they continued to be built until the 1890s.

The [[LDE – Pegasus|Pegasus]] of 1839 was the first locomotive to be built by the [[Sächsische Maschinenbau-Compagnie]] in [[Chemnitz]]. [[August Borsig]] and Company manufactured [[Beuth]] in 1843 which was highly successful; its valve design became de facto standard for locomotives for decades to come.<ref>Christopher Chant, 'The World's Railways, Regency House Publishing (2001)1552671607</ref> By 1846 he had manufactured more than a hundred similar locomotives. Both the [[Leipzig-Dresden Railway]] and [[Royal Bavarian State Railways]] (Königlich Bayerische Staatsbahn) built several 2-2-2 classes 1841-1859.

Replica of Adler at Fürth, May 2008 Under the Whyte notation for the classification of steam locomotives, 2-2-2 represents the wheel arrangement of two leading wheels on one axle, two powered driving wheels on one axle, and two trailing wheels on one axle. The wheel arrangement both provided more stability and enabled a larger firebox than the earlier 0-2-2 and 2-2-0 types. This configuration was introduced in 1834 on Robert Stephenson's 'Patentee locomotive' but it was later popularly named Jenny Lind, after the Jenny Lind locomotive which in turn was named after the popular singer. They were also sometimes described as Singles, although this name could be used to describe any kind of locomotive with a single pair of driving wheels. Contents 1 Equivalent classifications 2 History 2.1 Later UK developments 2.2 Belgium 2.3 Italy 2.4 Germany 2.5 Austria 3 Preserved examples &amp; replicas 4 External links 5 References Equivalent classifications[edit] Other equivalent classifications are: UIC classification: 1A1 (also known as German classification and Italian classification) French classification: 111 Turkish classification: 13 Swiss classification: 1/3 History[edit] The 2-2-2 configuration appears to have been developed by Robert Stephenson and Company in 1834, as an enlargement of their 2-2-0 Planet configuration, offering more stability and a larger firebox. The new type became known as Stephenson's Patentee locomotive.[1] Adler, the first successful locomotive to operate in Germany, was a Patentee supplied by Robert Stephenson and company in component form in December, 1835 was one of the earliest examples. Other examples were exported to the Netherlands, Russia and Italy.[2] By 1838 the 2-2-2 had become the standard passenger design by Robert Stephenson and Company.[3] Eighteen of the first nineteen locomotives ordered by Isambard Kingdom Brunel for the opening of the Great Western Railway in 1837/8 were of the 2-2-2 type.[4] These included six 2-2-2 locomotives built by Charles Tayleur at his Vulcan Foundry. Also in 1837 the successful North Star broad gauge locomotive was delivered to the Great Western Railway by Stephenson, becoming the first of a class of twelve locomotives by 1841. Great Western Railway North Star at Swindon Later UK developments[edit] Sharp, Roberts and Company constructed more than 600 2-2-2 locomotives between 1837 and 1857. Ten of these supplied to the Grand Junction Railway became the basis of Alexander Allan's successful designs for the railway from 1845 (the first of which, formerly named Columbine, is preserved). J. &amp; G. Rennie supplied 2-2-2 locomotives to the London and Croydon Railway from 1838 and the London and Brighton Railway in 1840.[5] Arend (eagle) was one of the two first steam locomotives in the Netherlands, built by R. B. Longridge and Company of Bedlington, Northumberland in 1839. The Great Western Railway continued to order both broad gauge and standard gauge locomotives on the railway, including the Firefly and Sun classes (1840–42), which were enlarged versions of North Star. Bury, Curtis, and Kennedy supplied six 2-2-2 locomotives to the Bristol and Gloucester Railway in 1844, and fourteen to the Great Southern and Western Railway in Ireland in 1848, (the last of these has been preserved at Cork Kent railway station. The original "Jenny Lind" locomotive, 1847. The Jenny Lind locomotive, designed by David Joy and built in 1847 for the London Brighton and South Coast Railway by the E.B.Wilson and Company of Leeds, became the basis of hundreds of similar passenger locomotives built during the 1840s and 1850s by this and other manufacturers for UK railways. The London &amp; North Western Railway Cornwall locomotive was designed at Crewe Works as a 4-2-2 by Francis Trevithick in 1847, but was rebuilt as a 2-2-2 in 1858. Although by the 1860s the 2-2-2 configuration was beginning to be superseded by the 2-4-0 type with better adhesion, the invention of steam sanding gave 2-2-2 singles a new lease of life, and they continued to be built until the 1890s. Notable late examples include William Stroudley's singles of 1874-1880, William Dean's 157 class of 1878-79,[6] and his 3001 class (1891–92),[7][8] both for the Great Western Railway. James Holden of the Great Eastern Railway created some 2-2-2 singles in 1889 by removing the side rod from a 2-4-0. Belgium[edit] Replica of 'Le Belge' 1835 The first steam railway locomotive built in Belgium in 1835, and was built by John Cockerill under license to a design by Robert Stephenson &amp; Co. It was built for use on the first main line on the European mainland, the Brussels-Mechelen line.[9] A replica was built at the workshops of Boissellerie Cognaut for the 150th anniversary of the formation of Belgium.[10] Italy[edit] Two 2-2-2 locomotives were imported from Longridge and Co of Bedlington Ironworks England for the Naples–Portici railway in 1839 named Bayard and Vesuvio. A replica of 'Bayard is at the Naples Railway Museum.[11] Germany[edit] Most of the earliest locomotives to operate in what is now Germany before the mid-1840s were 2-2-2s delivered by UK manufacturers. However by 1839 the type was also being built locally see List of Bavarian locomotives and railbuses. The Pegasus of 1839 was the first locomotive to be built by the Sächsische Maschinenbau-Compagnie in Chemnitz. August Borsig and Company manufactured Beuth in 1843 which was highly successful; its valve design became de facto standard for locomotives for decades to come.[12] By 1846 he had manufactured more than a hundred similar locomotives. Both the Leipzig-Dresden Railway and Royal Bavarian State Railways (Königlich Bayerische Staatsbahn) built several 2-2-2 classes 1841-1859. Similarly, the Grand Duchy of Mecklenburg Friedrich-Franz Railway grouped various 2-2-2 steam locomotives procured from German manufacturers between 1848 and 1863 into its Mecklenburg I class. Austria[edit] The Imperial Austrian State Railways (kaiserlich-königliche österreichische Staatsbahnen or kkStB) built two successful locomotives of this wheel arrangement in 1907. Similarly the Federal Railway of Austria (BBÖ) built two examples of an express tank locomotive in 1934 and 1937.

Replica of Adler at Fürth, May 2008 Under the Whyte notation for the classification of steam locomotives, 2-2-2 represents the wheel arrangement of two leading wheels on one axle, two powered driving wheels on one axle, and two trailing wheels on one axle. The wheel arrangement both provided more stability and enabled a larger firebox than the earlier 0-2-2 and 2-2-0 types. This configuration was introduced in 1834 on Robert Stephenson's 'Patentee locomotive' but it was later popularly named Jenny Lind, after the Jenny Lind locomotive which in turn was named after the popular singer. They were also sometimes described as Singles, although this name could be used to describe any kind of locomotive with a single pair of driving wheels. Contents 1 Equivalent classifications 2 History 2.1 Later UK developments 2.2 Belgium 2.3 Italy 2.4 Germany 2.5 Austria 3 Preserved examples &amp; replicas 4 External links 5 References Equivalent classifications[edit] Other equivalent classifications are: UIC classification: 1A1 (also known as German classification and Italian classification) French classification: 111 Turkish classification: 13 Swiss classification: 1/3 History[edit] The 2-2-2 configuration appears to have been developed by Robert Stephenson and Company in 1834, as an enlargement of their 2-2-0 Planet configuration, offering more stability and a larger firebox. The new type became known as Stephenson's Patentee locomotive.[1] Adler, the first successful locomotive to operate in Germany, was a Patentee supplied by Robert Stephenson and company in component form in December, 1835 was one of the earliest examples. Other examples were exported to the Netherlands, Russia and Italy.[2] By 1838 the 2-2-2 had become the standard passenger design by Robert Stephenson and Company.[3] Eighteen of the first nineteen locomotives ordered by Isambard Kingdom Brunel for the opening of the Great Western Railway in 1837/8 were of the 2-2-2 type.[4] These included six 2-2-2 locomotives built by Charles Tayleur at his Vulcan Foundry. Also in 1837 the successful North Star broad gauge locomotive was delivered to the Great Western Railway by Stephenson, becoming the first of a class of twelve locomotives by 1841. Great Western Railway North Star at Swindon Later UK developments[edit] Sharp, Roberts and Company constructed more than 600 2-2-2 locomotives between 1837 and 1857. Ten of these supplied to the Grand Junction Railway became the basis of Alexander Allan's successful designs for the railway from 1845 (the first of which, formerly named Columbine, is preserved). J. &amp; G. Rennie supplied 2-2-2 locomotives to the London and Croydon Railway from 1838 and the London and Brighton Railway in 1840.[5] Arend (eagle) was one of the two first steam locomotives in the Netherlands, built by R. B. Longridge and Company of Bedlington, Northumberland in 1839. The Great Western Railway continued to order both broad gauge and standard gauge locomotives on the railway, including the Firefly and Sun classes (1840–42), which were enlarged versions of North Star. Bury, Curtis, and Kennedy supplied six 2-2-2 locomotives to the Bristol and Gloucester Railway in 1844, and fourteen to the Great Southern and Western Railway in Ireland in 1848, (the last of these has been preserved at Cork Kent railway station. The original "Jenny Lind" locomotive, 1847. The Jenny Lind locomotive, designed by David Joy and built in 1847 for the London Brighton and South Coast Railway by the E.B.Wilson and Company of Leeds, became the basis of hundreds of similar passenger locomotives built during the 1840s and 1850s by this and other manufacturers for UK railways. The London &amp; North Western Railway Cornwall locomotive was designed at Crewe Works as a 4-2-2 by Francis Trevithick in 1847, but was rebuilt as a 2-2-2 in 1858. Although by the 1860s the 2-2-2 configuration was beginning to be superseded by the 2-4-0 type with better adhesion, the invention of steam sanding gave 2-2-2 singles a new lease of life, and they continued to be built until the 1890s. Notable late examples include William Stroudley's singles of 1874-1880, William Dean's 157 class of 1878-79,[6] and his 3001 class (1891–92),[7][8] both for the Great Western Railway. James Holden of the Great Eastern Railway created some 2-2-2 singles in 1889 by removing the side rod from a 2-4-0. Belgium[edit] Replica of 'Le Belge' 1835 The first steam railway locomotive built in Belgium in 1835, and was built by John Cockerill under license to a design by Robert Stephenson &amp; Co. It was built for use on the first main line on the European mainland, the Brussels-Mechelen line.[9] A replica was built at the workshops of Boissellerie Cognaut for the 150th anniversary of the formation of Belgium.[10] Italy[edit] Two 2-2-2 locomotives were imported from Longridge and Co of Bedlington Ironworks England for the Naples–Portici railway in 1839 named Bayard and Vesuvio. A replica of 'Bayard is at the Naples Railway Museum.[11] Germany[edit] Most of the earliest locomotives to operate in what is now Germany before the mid-1840s were 2-2-2s delivered by UK manufacturers. However by 1839 the type was also being built locally see List of Bavarian locomotives and railbuses. The Pegasus of 1839 was the first locomotive to be built by the Sächsische Maschinenbau-Compagnie in Chemnitz. August Borsig and Company manufactured Beuth in 1843 which was highly successful; its valve design became de facto standard for locomotives for decades to come.[12] By 1846 he had manufactured more than a hundred similar locomotives. Both the Leipzig-Dresden Railway and Royal Bavarian State Railways (Königlich Bayerische Staatsbahn) built several 2-2-2 classes 1841-1859. Similarly, the Grand Duchy of Mecklenburg Friedrich-Franz Railway grouped various 2-2-2 steam locomotives procured from German manufacturers between 1848 and 1863 into its Mecklenburg I class. Austria[edit] The Imperial Austrian State Railways (kaiserlich-königliche österreichische Staatsbahnen or kkStB) built two successful locomotives of this wheel arrangement in 1907. Similarly the Federal Railway of Austria (BBÖ) built two examples of an express tank locomotive in 1934 and 1937. Preserved examples &amp; replicas[edit] The locomotive "Pioneer" in service on the Cumberland Valley Railroad in the 1880s or 1890s.
