Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles and two trailing wheels on one axle.
While some locomotives with this wheel arrangement had tenders, the majority were tank locomotives which carried their coal and water onboard.
Finland used two classes of 0-6-2T locomotive, the Vr2 and the Vr5.
The Vr2 class was numbered in the range from 950 to 965. Five of them are preserved in Finland, no. 950 at Joensuu, no. 951 at Tuuri, no. 953 at Haapamäki, no. 961 at Jyväskylä and no. 964 at the Veturimuseo at Toijala.
The Vr5 class was numbered in the range from 1400 to 1423. No. 1422 is preserved at Haapamäki.
Nederlandsch Indische Spoorweg Maatschappij or NIS received 10 0-6-2Ts (skirt tank) from Sächsische Maschinenfabrik (Hartmann) in 1903 and 1912 worked for mixed passenger and freight trains on the 3 ft 6 in (1067 mm) Gundih–Gambringan–Cepu–Surabaya NIS and sugarcane freight train on Solo–Wonogiri–Baturetno lines which managed by them. A 0-6-2T also worked on Batavia–Buitenzorg line.[1] These 0-6-2Ts were classified as NIS Class 350 (351-360) using both wood and coal as fuel. However, the NIS 350s used teak wood more often due to the increasing consumption of coal making it difficult to get it. Teak wood is easy to obtain along the Gundih–Surabaya line, especially in the vicinity of Bojonegoro where there are still many teak forests. These NIS 350s have limitation, technically, the position of the tank is on the side of the wheels and only has a water capacity of 3 m3. This small tank capacity, it limits the operating range of NIS 350s that had to haul NIS essential commodity trains on certain routes. They quickly ran out of water, so they had to frequently stop at the station to fill the tank with water. To overcome this obstacle, especially when entering the dry season, a water tower or reservoir was built at each station. After Japanese occupation and Indonesian Independence, these locomotives were renumbered as C20 class.[2] The C20 locomotive has a length of 9420 mm and weighs 33.5 tons, and able to run a maximum speed of 60 kilometres per hour (37 miles per hour). From 10 of them, only C20 01 is preserved at Ambarawa Railway Museum, Central Java.
There were 30 Dagupan-type locomotives built between 1889 and 1890. All were tank locomotives, weighed 32t and were run a maximum speed of 33km/h.[3] These were divided into two subclasses: the A subclass built by Neilson and Company and the B subclass built by Dübs and Company.[4]
Another 25 locomotives of the C class were built in 1906 by the North British Locomotive Company (which succeeded Dübs) and were regarded as distinct from the Dagupan class.[4]
During the Manila Railroad era, they were replaced in mainline service by American tender locomotives such as the Porter 4-6-0 built in 1919 or the 4-6-2 Pacifics built by Baldwin Locomotive Works between 1926 and 1929.[4]
A B-class locomotive named Urdaneta (No. 17) remained in shunting service until 1963 and is one of only three steam locomotives preserved by the PNR. After its retirement, Urdaneta was first displayed in the Tutuban station. It is now on static display in Dagupan, Pangasinan.[5] The rest were scrapped between 1917 and 1940.[4]
Ma-Ao Sugar Central of Negros Occidental had locomotive No. 8, a rebuild of a saddle tank locomotive built in 1920.[6] It was last seen in January 1982 and was presumed to have been scrapped not long after due to the mill being in a decrepit state during those years.[7]
Between 1890 and 1898, four 0-6-2 tender locomotives were placed in service by the Cape Copper Company on its gauge Namaqualand Railway between Port Nolloth and O'okiep in the Cape Colony. Acquired to meet the traffic needs of the upper mountainous section of the line, they became known as the Mountain type. The first three of these locomotives were later described as the Clara Class, while the fourth was included in this Class by some and included in the subsequent Scotia Class by others.
Between 1900 and 1905, six more Mountain type 0-6-2 tender locomotives were placed in service by the Cape Copper Company. Later described as the Scotia Class, they were similar to the earlier Clara Class locomotives, but with longer boilers, longer fireboxes and larger firegrates.
In 1892 and 1893, the Nederlandsche-Zuid-Afrikaansche Spoorweg-Maatschappij of the Zuid-Afrikaansche Republiek (Transvaal Republic) placed twenty 0-6-2T locomotives in mainline service. Since the railway classified its locomotives according to their weight, these locomotives were known as the .
Three classes of gauge 0-6-2 locomotives were supplied to German South West Africa between 1904 and 1908.
In the United Kingdom, the type was only ever used for tank engines and was first used by William Barton Wright of the Lancashire and Yorkshire Railway in 1880 with the L&YR Barton Wright 0-6-2T.[8]
The arrangement was soon afterwards used by Francis Webb of the London and North Western Railway on his famous Coal Tanks of 1881–1897. Many locomotives of this type were also used to haul coal in the South Wales Valleys by the Great Western Railway and its predecessors.
Several railways around London later used the type for heavy suburban passenger trains, notably the following:
Gresley later improved upon the GER class with various versions of his London and North Eastern Railway (LNER) N7 class, built between 1925 and 1928.
In 1904, the Lambton Railway ordered their first 0-6-2T from Kitson & Co. to use on the collery systems. This proved to be successful over the next few years a further 6 0-6-2T were ordered, 2 in 1907 provided by Kitson, 2 in 1909 provided by Robert Stephenson & Co., another provided by Stephenson in 1920, and a final in 1934 provided by Hawthorn Leslie.[9] In 1931, the railway bought 5 0-6-2Ts from the Great Western Railway, three of which were from the former Taff Vale Railway, and the remainder from the Cardiff Railway.
The primary usage of 0-6-2 types in the United States were Tank locomotives. Many were found in the state of Hawaii on sugar cane railroads across the state. Most notable were the 0-6-2T's of the Mcbryde Sugar Company of Kauai, 3 of which survive and are currently the only original steam engines operating in Hawaii.
