The Queensland Railways A12 class locomotive was a class of 4-4-0 steam locomotives operated by the Queensland Railways.
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.
A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible material – usually coal, wood, or oil – to produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (drivers). Both fuel and water supplies are carried with the locomotive, either on the locomotive itself or in wagons (tenders) pulled behind.
Queensland Rail, also known as QR, is a railway operator in Queensland, Australia. Owned by the Queensland Government, it operates suburban and long-distance passenger services, as well as owning and maintaining approximately 6,600 kilometres of track.
Between 1882 and 1895, the Queensland Railways took delivery of 43 4-4-0 locomotives built by Baldwin Locomotive Works (18) and Evans, Anderson, Phelan & Co (25). Per Queensland Railway's classification system they were designated the A12 class, A representing they had two driving axles, and the 12 the cylinder diameter in inches. [1]
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.
Evans, Anderson, Phelan & Co was an Australian engineering and railway rolling stock manufacturer, located at Kangaroo Point, Queensland. It manufactured steam locomotives for the Queensland Railways until 1927. The works were not located near a railway, so completed locomotives were delivered along Main Street on temporary track.
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons. On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods ; normally one pair is directly driven by the main rod which is connected to the end of the piston rod; power is transmitted to the others through the side rods.
The Australian Standard Garratt (ASG) was a Garratt steam locomotive designed in Australia during World War II, and used on 3 ft 6 in narrow gauge railway systems in Queensland, South Australia, Western Australia and Tasmania.
The EMD G12 was a class of locomotive built by GM-EMD, and its Canadian affiliate General Motors Diesel. In addition, Australian licensee Clyde Engineering built ten locomotives for New Zealand in 1957, five for Hong Kong, 23 for Queensland, 14 for Western Australia and seven for BHP. Australian licensee Commonwealth Engineering also built 42 for Queensland Rail in 1964–66. Many examples were built in the 1950-1960s for railroads all over the world.
