The South Australian Railways O Class (1st) Locomotives were built by Baldwin Locomotive Works for the South Australian Railways. They entered service in 1881 on the S.A.R. system and were both withdrawn and scrapped by 1904. [1]
These two locomotives built by Baldwin Locomotive Works USA for the South Australian Railways and formed the O class. Their main job was for hauling goods trains on the Intercolonial Railway. When they were first in service they became the largest locomotives on the S.A.R. system. Though it wasn't to be all that it seemed to be, the O class were unsuccessful. They were not successful performers on the Adelaide Hills line and instead were diverted to work on the Northern line. With the great success from the new R class (4-6-0) locomotives that arrived in 1886, the two O class (2-8-0) locomotives were pulled from service in 1904 with only a short working life of 23 years.

The Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1956. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete as demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1956 and went out of business in 1972.
Under the Whyte notation for the classification of steam locomotives, 4-6-2 represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The 4-6-2 locomotive became almost globally known as a Pacific type.
4-4-0 is a locomotive type with a classification that uses the Whyte notation for the classification of steam locomotives by wheel arrangement and represents the arrangement: four leading wheels on two axles, four powered and coupled driving wheels on two axles, and a lack of trailing wheels. Due to the large number of the type that were produced and used in the United States, the 4-4-0 is most commonly known as the American type, but the type subsequently also became popular in the United Kingdom, where large numbers were produced.
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 4-6-0 represents the configuration of four leading wheels on two axles in a leading bogie and six powered and coupled driving wheels on three axles with the absence of trailing wheels. In the mid 19th century, this wheel arrangement became the second most popular configuration for new steam locomotives in the United States, where this type is commonly referred to as a ten-wheeler. As a locomotive pulling trains of lightweight all-wood passenger cars in the 1890–1920s, it was exceptionally stable at near 100 mph (160 km/h) speeds on the New York Central's New York to Chicago Water Level Route and on the Reading Railroad's Camden to Atlantic City, NJ, line. As passenger equipment grew heavier with all steel construction, heavier locomotives replaced the ten-wheeler.
Under the Whyte notation for the classification of steam locomotives, 2-6-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels. This arrangement is commonly called a Mogul.
Under the Whyte notation for the classification of steam locomotives, 2-8-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. In the United States and elsewhere, this wheel arrangement is commonly known as a Consolidation, after the Lehigh and Mahanoy Railroad’s Consolidation, the name of the first 2-8-0.
Under the Whyte notation for the classification of steam locomotives, 2-8-2 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles and two trailing wheels on one axle, usually in a trailing truck. This configuration of steam locomotive is most often referred to as a Mikado, frequently shortened to Mike.
Under the Whyte notation for the classification of steam locomotives, 4-8-0 represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck or bogie, eight powered and coupled driving wheels on four axles and no trailing wheels. In North America and in some other countries the type was usually known as the Twelve-wheeler.
Under the Whyte notation for the classification of steam locomotives, a 2-6-4 locomotive has two leading wheels, six coupled driving wheels and four trailing wheels. This arrangement is commonly called Adriatic.
Under the Whyte notation for the classification of steam locomotives, 2-4-2 represents the wheel arrangement of two leading wheels on one axle, four powered and coupled driving wheels on two axles and two trailing wheels on one axle. The type is sometimes named Columbia after a Baldwin 2-4-2 locomotive was showcased at the 1893 World's Columbian Exposition held at Chicago, Illinois.
Under the Whyte notation for the classification of steam locomotives, 2-6-2 represents the wheel arrangement of two leading wheels, six coupled driving wheels and two trailing wheels. This arrangement is commonly called a Prairie.
Under the Whyte notation for the classification of steam locomotives, 0-4-2 represents the wheel arrangement with no leading wheels, four powered and coupled driving wheels on two axles and two trailing wheels on one axle. While the first locomotives of this wheel arrangement were tender engines, the configuration was later often used for tank engines, which is noted by adding letter suffixes to the configuration, such as 0-4-2T for a conventional side-tank locomotive, 0-4-2ST for a saddle-tank locomotive, 0-4-2WT for a well-tank locomotive and 0-4-2RT for a rack-equipped tank locomotive. The arrangement is sometimes known as Olomana after a Hawaiian 0-4-2 locomotive of 1883.
Under the Whyte notation for the classification of steam locomotives, 0-6-2 represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The type is sometimes known as a Webb or a Branchliner.
The United States Army Transportation Corps S160 Class is a class of 2-8-0 Consolidation steam locomotive designed for use in Europe during World War II for heavy freight work. A total of 2,120 were built and they worked on railroads across the world, including Africa, Asia, all of Europe and South America.
South Australian Railways (SAR) was the statutory corporation through which the Government of South Australia built and operated railways in South Australia from 1854 until March 1978, when its non-urban railways were incorporated into Australian National, and its Adelaide urban lines were transferred to the State Transport Authority.
The South African Railways Class 7E 4-8-0 of 1899 was a steam locomotive from the pre-Union era in the Cape of Good Hope.
The South African Railways Class NG8 4-6-0 of 1904 was a narrow-gauge steam locomotive from the pre-Union era in the Cape of Good Hope.
The Natal Government Railways Class I 2-6-0 of 1902 was a South African steam locomotive from the pre-Union era in the Colony of Natal.
The South Australian Railways C Class Locomotives were built by the Robert Stephenson and Company for the South Australian Railways in 1856. The first locomotive numbered 5 was in service by November 1856, the second locomotive numbered 6 was in service by January 1857. They spent many years with the South Australian Railways and were both rebuilt over the years. They were both withdrawn from service after having a number of years on their service record with No. 5 being withdrawn after 50 years worth of service for the SAR. No. 6 lasted well into Commissioner Webbs era, after being withdrawn in 1926 with almost 70 years of service for the SAR.
The South Australian Railways N Class Locomotives were built in 1881 by the Baldwin Locomotive Works for the South Australian Railways (S.A.R.). They were rebuilt in 1904, which vastly improved their performance and completely changed their look from a typical American locomotive of the time to a more British one.
