Under theWhyte notation for the classification ofsteam locomotives,0-4-0 represents one of the simplest possible types, that with two axles and four coupled wheels, all of which are driven. The wheels on the earliest four-coupled locomotives were connected by a singlegear wheel, but from 1825 the wheels were usually connected withcoupling rods to form a single driven set.
The notation0-4-0T indicates atank locomotive of this wheel arrangement on which its water and fuel is carried on board the engine itself, rather than in an attachedtender.
In Britain, the Whyte notation of wheel arrangement was also often used for the classification of electric and diesel-electric locomotives with side-rod-coupled driving wheels.[1]
Under theUIC classification used in Europe and, in more recent years, in simplified form in the United States, a 0-4-0 is classified asB (German and Italian) if the axles are connected by side rods or gearing and 020 (French), independent of axle motoring. The UIC'sBo classification for electric and diesel-electric locomotives indicates that the axles are independently motored, which would be0-2-2-0 under the Whyte notation.
0-4-0 locomotives were built astank locomotives as well astender locomotives. The former were more common in Europe and the latter in the United States, except in the tightest of situations such as that of a shopswitcher locomotive, where overall length was a concern. The earliest 0-4-0 locomotives were tender engines and appeared as early as c. 1802. The 0-4-0tank engines were introduced in the early 1850s. The type was found to be so useful in many locations that they continued to be built for more than a century and existed until the end of the steam era.
Richard Trevithick'sCoalbrookedale (1802),Pen-y-Darren (1804) andNewcastle (1805) locomotives were of the 0-4-0 type, although in their cases the wheels were connected by a single gear wheel. The first 0-4-0 to use coupling rods wasLocomotion No. 1, built byRobert Stephenson and Company for theStockton and Darlington Railway in 1825. Stephenson also built theLancashire Witch in 1828, andTimothy Hackworth builtSans Pareil which ran at theRainhill Trials in 1829. The latter two locomotives later worked on theBolton and Leigh Railway.
A four-wheeled configuration, where all the wheels aredriving wheels, uses all the locomotive's mass for traction but is inherently unstable at speed. The type was therefore mainly used forswitcher locomotives (also known as shunter locomotives in the United Kingdom). Because of the lack of stability,tender engines of this type were only built for a few decades in the United Kingdom. They were built for a longer period in the United States.
The possibletractive effort of an 0-4-0 within normal axle load limits was not enough to move large loads. By 1900, they had therefore largely been superseded for most purposes by locomotives with more complex wheel arrangements. They nevertheless continued to be used in situations where tighter radius curves existed or the shorter length was an advantage. Thus, they were commonly employed indockyard work,industrial tramways, or as shop switchers.
The wheel arrangement was also used on specialised types such asfireless locomotives,crane tank locomotives,tram engines andgeared steam locomotives. It was also widely used onnarrow gauge railways.
In New South Wales,Dorrigo Steam Railway and Museum has preserved twelve 0-4-0 steam locomotives and eight 0-4-0 diesel locomotives, a total of twenty examples, all on the one site.

In Tyrol,Achensee Railway operates three 0-4-0 geared steam cog locomotives on their 1 meter narrow gauge tourist railway and has one on display. The locomotives were originally built by Wiener Lokomotivfabrik, but one has been rebuilt from scavenged parts.
TheCatumbela Sugar Estate inAngola operated a narrow gauge line on the estate. One of their0-4-0 locomotives, Rührthaler Maschinen-Fabrik 963 of 1929, was later rebuilt with a diesel engine.[2]
Finland had the E1 andVk4 classes with an 0-4-0 wheel arrangement.
The E1 was a class of only two locomotives, numbered 76 and 77.
The Vk4 was also a class of only two locomotives, built byBorsig Lokomotiv Werke (AEG) of Germany in 1910. The Vk4s were used at a fortress, and were eventually also used in dismantling the fortress, after which one locomotive went into industrial use and was scrapped in 1951. The other was sold to theFinnish Railways and nicknamedLeena. It became No. 68 and is now the oldest working broad gauge locomotive in Finland, being preserved at theFinnish Railway Museum.
TheSamarang-Cheribon Stoomtram Maatschappij or SCS imported 27cape gauge 0-4-0T SCS Class 100 locomotives between 1908 and 1911, originally to operate services from Kalibrodi-Samarang toTanggung and Yogyakarta. They were built bySächsische Maschinenfabrik inChemnitz, Germany. They were a modern locomotive design for the time, equipped with asuperheater.
The largest allocation of SCS 100s were inTegal, Central Java for services toPurwokerto. Some were later converted to tram engines and worked in Tegal andPurwokerto.
AfterJapanese occupation and Indonesian Independence, these locomotives were renumbered to B52 class. All 27 locomotives were in existence at the end of 1960, but by 1970 only 15 units remained. Two locomotives have been preserved, B5212 at the Transportation Museum ofTaman Mini Indonesia Indah and B5210 at theAmbarawa Railway Museum.
TheNZR A class of 1873 consisted of three engine types of similar specification but differing detail. They were British and New Zealand-built and several were preserved.
The only examples of this type in the Philippines were the fiveManila class light-duty tank locomotives built byHunslet Engine Company for the Manila Railway. They were ordered in 1885 for theTranvía system until they were used on theFerrocarril de Manila a Dagupan in the 1890s.[3] After being retired from the Manila Railroad in 1927,Manila was sold to the newly-formedCentral Azucarrera de Tarlac, where it was made into a tank-tender locomotive until the 1980s. The locomotive was scrapped byc. 1991.[citation needed]
In 1847, the government of theCape Colony established harbour boards at its three major ports,Table Bay,Port Elizabeth andEast London. While railway lines were laid at all these harbours, trains were for the most part initially hauled by oxen or mules. The first steam locomotives to see service at these harbours were7 ft 1⁄4 in (2,140 mm) Brunel gauge engines which were placed in service on breakwater construction at Table Bay Harbour in 1862 and East London Harbour in 1874.[4][5]
In September 1859 Messrs. E. & J. Pickering, contractors to the Cape Town Railway and Dock Company for the construction of the Cape Town-Wellington railway line, imported a small4 ft 8+1⁄2 in (1,435 mm) broad gauge 0-4-0 side-tank steam locomotive from England for use during the construction of the railway. This was the first locomotive in South Africa. In 1874 the locomotive was rebuilt to a 0-4-2T configuration before it was shipped toPort Alfred, where it served as construction locomotive on the banks of the Kowie river and wasnicknamedBlackie. It has been declared aheritage object and was plinthed in the main concourse of Cape Town station.[6][10]
The first railway locomotive to run in revenue earning service in South Africa was a small broad gauge 0-4-0WT well tank enginenamedNatal, manufactured by Carrett, Marshall and Company of Leeds. It made its inaugural run from Market Square to Point station in Durban during the official opening of the first operating railway in South Africa on Tuesday, 26 June 1860.[6][11][12][13][14]
In 1865, theNatal Railway Company obtained a saddle-tank locomotive with a0-4-0 wheel arrangement fromKitson and Company. This was the Natal Railway's second locomotive and wasnamedDurban.[6][15]
In 1878, while construction work by the Kowie Harbour Improvement Company was underway at Port Alfred, theCape Government Railways acquired one broad gauge0-4-0ST (Saddle Tank) locomotivenamedAid fromFox, Walker and Company of Bristol for use as construction locomotive on the east bank of the Kowie river.[6]
During the late 19th and early 20th centuries, a number of 0-4-0tank- and saddle-tank locomotives were imported into South Africa, many of them for use in harbours. Many of these locomotives came intoSouth African Railways (SAR) stock in 1912, but were never classified.[8]

Between 1886 and 1888,three well-tank condensing locomotives were placed in service by the Cape Copper Mining Company on its2 ft 6 in (762 mm)Namaqualand Railway betweenPort Nolloth andO'okiep in the Cape Colony. They were the first condensing steam locomotives to enter service in South Africa. They were later rebuilt as conventional well-tank locomotives.[24]
In 1899, Rand Mines acquired two narrow gauge tank steam locomotives from Avonside Engine Company and in 1900 a similar locomotive was delivered to Reynolds Brothers Sugar Estates in Natal. In 1915, when an urgent need arose for additional narrow gauge locomotives in German South West Africa during theFirst World War,these three locomotives were purchased second-hand by the South African Railways.[8][25]

In 1900 the British War Office placed two Sirdar class 0-4-0T tank steam locomotives in service on a2 ft (610 mm) narrow gauge line near Germiston in theZuid-Afrikaansche Republiek, where the Royal Engineers had established a siege park during theSecond Boer War. The locomotives were built byKerr, Stuart and Company. At the end of the war, the two Sirdar locomotives were sold to a farmer, who used them on a firewood line betweenPienaarsrivier and Pankop, until the line and locomotives were taken over by theCentral South African Railways (CSAR). In 1912, when these locomotives were assimilated into the SAR, they were renumbered with an "NG" prefix to their numbers. When a system of grouping narrow gauge locomotives into classes was eventually introduced by the SAR somewhere between 1928 and 1930, they were designatedClass NG1.[8][26]
In 1902, the CGR placed a single narrow gauge tank steam locomotive in service on the Avontuur branch, built byManning Wardle, classifiedType C and namedMidget. In 1912, this locomotive was assimilated into the South African Railways and renumbered. It was sold to the West Rand Consolidated Mines near Krugersdorp in 1921.[8][25]
A singlesmall five-ton locomotive, built byKrauss & Company, was purchased by the CGR c. 1903 and placed in service as construction engine on the narrow gaugeAvontuur branch out ofPort Elizabeth.[25][27]
The tank engine versions of the wheel arrangement began to appear in the United Kingdom in the early 1850s, with the first significant class being six saddle tanks designed byRobert Sinclair for theCaledonian Railway.
By 1860 the type was very popular and it continued to be built in significant numbers for bothmainline andindustrial railways, almost to the end of steam traction.Hudswell Clarke were supplyingindustrial saddle tanks until at least 1947,[28] and bothBarclay andRobert Stephenson and Hawthorns until 1949.[29]
An interesting variation on this theme were thetraction engine-based railway locomotives built byAveling and Porter.
The lastBritish Railways0-4-0ST dock shunters were built byHorwich Works as late as 1955 and survived until 1966.
During the 1840s, the wheel arrangement was widely used byEdward Bury on thebar-framed locomotives built for theLondon and Birmingham Railway. However, with the exception of a few isolated examples used by the smaller companies such as theCambrian Railways, theFurness Railway and theTaff Vale Railway, and four examples built byEdward Fletcher (engineer) of theNorth Eastern Railway between 1854 and 1868, the 0-4-0 tender locomotive had been largely superseded on Britain's mainline railways by 1850.[30]

An early example of the 0-4-0 vertical boiler type was theBaltimore and Ohio Railroad'sAtlantic No. 2, built in 1832 byPhineas Davis and Israel Gartner. In the United States, the 0-4-0 tank locomotive was principally used forindustrial railway purposes.
A locomotive based on these also appears inMario Kart 8's N64Rainbow Road and Merry Mountain tracks.
In the United States, theBest Friend of Charleston was the first locomotive to be built entirely within the United States. It was built in 1830 for theSouth Carolina Canal and Rail Road Company by theWest Point Foundry of New York.
TheJohn Bull was built byRobert Stephenson and Company for theCamden and Amboy Railroad in New Jersey in 1831, but was later rebuilt as a2-4-0.
ThePennsylvania Railroad kept producing0-4-0 classes long after all other major railroads had abandoned development of the type, building their finalA5s class into the 1920s. TheA5s was a monster among0-4-0s, larger than many0-6-0 designs, with modern features found on few others of its type, such assuperheating,power reverse, andpiston valves. ThePennsy continued to build the type because it had a large amount of confined and tight industrial track, more than most other railroads had.
The wheel arrangement was also used on a number of small 0-4-0DMdiesel-mechanicalshunters produced byJohn Fowler & Co. and other builders in the 1930s and earlier. Similarly, it was perpetuated on a number of diesel-mechanical and0-4-0DHdiesel-hydraulic classes between 1953 and 1960 (see theList of British Rail modern traction locomotive classes). Many of these were later sold for industrial use.
There are 0-4-0DEdiesel-electric locomotives too, although small in number. The smallest dieselswitchers, such as theEMD Model 40, were of this arrangement.
0-4-0 diesel-mechanical shunters are also PolishPKP class SM02 andPKP class SM03 and narrow gaugeWLs40/50.
