In 1899, the Walvis Bay Railway in the British territory of [[Walvis Bay]], a Cape of Good Hope [[Enclave and exclave|exclave]] in ''[[Deutsch-Südwest-Afrika]]'' (German South West Africa), placed a single tank locomotive in service. The [[Walvis Bay 2-4-2T|engine, named ''Hope'']] and built by [[Kerr, Stuart and Company]], remained in service until 1904 when operations on the railway were suspended. The line was abandoned in 1905, partly as a result of being buried by a sandstorm.<ref name="SAR&H Jan 1948">Espitalier, T.J.; Day, W.A.J. (1948).

===Finland===
A 2-4-2 tank locomotive, built by [[Baldwin Locomotive Works]] in 1899 and used on the private [[Raahe]] track in [[Finland]], was later bought by the [[Finnish State Railways]].

===New Zealand===

In 1877, when the [[New Zealand Railways Department|New Zealand Railways]] needed new motive power, the road turned to the [[Rogers Locomotive and Machine Works|Rogers Locomotive Works]] who supplied eight 2-4-2 tender locomotives between 1877 and 1879 that were designated the "K" class. These were the first American-built locomotives in New Zealand and proved to be quite successful.

Three of these locomotives have been preserved. No. K88 ''Washington'' was used on the first through train between Christchurch and Dunedin in 1877. After fifty years of service, ''Washington'' was dumped in the Oreti River, Southland, as a flood protection measure. In 1974, the locomotive was exhumed from her watery grave and, over the next eight years, restored to full active service.

Sister locomotives numbers K92 and K94 have also been salvaged from the Oreti river. No. K92 has been restored to full active service and has re-established her position on the [[Kingston Flyer]] train, which was made famous by the K class at the end of the 19th century.

===United Kingdom===

The earliest British use of the 2-4-2 wheel arrangement appears to have been no. 21 ''White Raven'', supplied to the [[St Helens Railway]] by James Cross of Sutton Works in 1863. It was soon rebuilt as a [[2-4-0]] [[tender locomotive]] and eventually passed into the stock of the [[London and North Western Railway]] (L&NWR).<ref>{{cite book | title= British Locomotive Catalogue 1825-1923 | last=Baxter | first=Bertram | volume=2A | publisher = Moorland Publishing | date=1978 | isbn= 9780903485517 | oclc= 877634366 | pages=48 }}</ref>

In 1864, [[Robert Sinclair (locomotive engineer)|Robert Sinclair]] of the [[Great Eastern Railway]] designed the first of six 2-4-2 tank classes built by the railway, eventually totalling 262 locomotives by 1912.

[[Francis Webb (engineer)|Francis Webb]] of the [[Locomotives of the London and North Western Railway|London and North Western Railway]] also designed two 2-4-2 classes which eventually totaled 380 locomotives, built between 1879 and 1898.

Other railway companies that built large numbers of the type included the [[Lancashire and Yorkshire Railway]] (L&YR) with 330 locomotives built between 1889 and 1911, the [[North Eastern Railway (UK)|North Eastern Railway]] with 60 locomotives built between 1886 and 1892 and the [[Manchester, Sheffield and Lincolnshire Railway]] with 49 locomotives built between 1889 and 1898. One of [[John Aspinall (engineer)|John Aspinall's]] [[L&YR Class 5|Class 5]] locomotives, built for the L&YR in 1889, is preserved at the [[National Railway Museum]], [[York]].

===United States===
[[File:St. Louis, Iron Mountain & Southern -5 (Porter 2-4-2) - 10570956923.jpg|left|thumb|[[St. Louis, Iron Mountain and Southern Railway 5]] was built as a 2-4-2T, but it was later modified as a tender engine by the [[Crab Orchard and Egyptian Railway]].]]

The tank-type 2-4-2T was common in the U.S. around the dawn of the twentieth century in both suburban passenger service and on logging railroads. The [[Baldwin Locomotive Works]] built a demonstrator tender type engine which was displayed at the Columbian Exposition of 1893, leading to the type's name. This locomotive featured ambitious seven foot tall driving wheels, and was one of the first tender-equipped locomotives with a trailing truck. This freed the firebox from having to sit narrowly between, or above, the drive wheels, and was a very influential design.

This inspired three major U.S. railroads ([[Atlantic Coast Line Railroad|Atlantic Coast Line]], [[Chicago, Burlington and Quincy Railroad|Burlington]] and [[Reading Company|Reading]]) to purchase a few of the type. But the two-wheeled lead truck was never well-suited to high speed service on far-flung North American rails. Some were converted to [[4-4-2 (locomotive)|4-4-2]] Atlantic types and others were converted to [[4-6-0]] Ten Wheelers. The display locomotive was donated to Columbia University. In one respect, however, it was a success. A great many Atlantic types would follow, most based on the design.<ref>{{Cite web|url=https://www.steamlocomotive.com/locobase.php?country=USA&wheel=2-4-2&railroad=baldwin|title = Baldwin 2-4-2 "Columbian" Locomotives in the USA}}</ref>
