Locomotives Of The Western Australian Government Railways
The Western Australian Government Railways (usually abbreviated to WAGR) operated many unique steam, diesel and electric locomotive classes. Often suffering from lack of available funds the WAGR locomotive fleet often consisted of locomotives far older than their expected operational life. Only one electric locomotive was operated by the government during the WAGR years. Early steam locomotives The first WAGR locomotives were two 1875 2-6-0 tender engines, later classified as the M class, built in England in 1875 and shipped to WA by sea. They operated on the first government railway in Geraldton, some 450 km north of Perth.Geoffrey Higham, (2007).

WAGR N Class
The WAGR N class was a class of steam locomotives operated by the Western Australian Government Railways (WAGR) from 1896 until 1960. History In September 1896, five Neilson & Co built N class entered service hauling suburban trains around Perth between Fremantle and Midland Junction and on the Kalgoorlie-Boulder loop. Robert Stephenson & Co built a further twelve in 1898/99 and Nasmyth, Wilson & Co a further fifteen in 1901. In 1907/08 a further ten were added, when the Midland Railway Workshops converted ten O class. With the cessation of suburban services in Kalgoorlie, all were transferred to Perth. Most remained in service until replaced by Dm and Dd class locomotives in the 1940s and ADH class diesel multiple units in the 1950s. The last two were withdrawn in September 1960. N201 has been preserved at the Western Australian Rail Transport Museum. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garratt
A Garratt (often referred to as a Beyer Garratt) is a type of steam locomotive invented by British engineer Herbert William Garratt that is articulated into three parts. Its boiler, firebox, and cab are mounted on a centre frame or "bridge". The two other parts, one at each end, have a pivot to support the central frame; they consist of a steam engine unit – with driving wheels, trailing wheels, valve gear, and cylinders, and above it, fuel and/or water storage. Articulation permits locomotives to negotiate curves that might restrict large rigid-framed locomotives. The design also provides more driving wheels per unit of locomotive weight, permitting operation on lightly engineered track. Garratt locomotives produced as much as twice the power output of the largest conventional locomotives of railways that introduced them, reducing the need for multiple locomotives and crews. Advantages of the Garratt concept The principal benefit of the Garratt design is that the boil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Msa Garratt
The WAGR Msa class was a class of Garratt-type articulated steam locomotives. The class was built at the Midland Railway Workshops and operated by the Western Australian Government Railways (WAGR) between 1930 and 1963. It was the first Garatt type to be designed and constructed entirely in Australia. History The class was preceded on the WAGR system by the M/Ms class Garratts. The class were used extensively on WAGR lines with light rails and sharp curves, as a consequence many of the smaller older branch lines on the Darling Scarp; as well as those with steep inclines such as those on the Mundaring Weir, Nannup, and Flinders Bay lines. In their later years, the boiler pressure was reduced to match that of the M/Ms class. By this stage they had been concentrated on the Bunbury to Boyup Brook and Pinjarra to Boddington lines. Hearsay evidence suggests that the poor quality of the boilers in the Msa rendered some inoperable by the late 1940s. The last remaining Msa was a ...

Superheater
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres). Types * A radiant superheater is placed directly in radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. * A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. * A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pipes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WAGR Ec Class
The WAGR Ec class was a class of 4-6-2 heavy passenger and goods Vauclain compound locomotives operated by the Western Australian Government Railways (WAGR) between 1901 and 1958. History A total of 20 Ec class engines were built by Baldwin Locomotive Works, Philadelphia Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Sinc ..., in the first half of 1901, and entered service with the WAGR later that year. The following year, Baldwin built the first of two batches of the WAGR C class, C class, a lighter version of the Ec class. Initially, the Ec class' main task was to haul heavy trains on the Eastern Goldfields Railway. Between 1920 and 1923, nine Ec class engines were lightened for use on the lightly laid Northam railway station, Western Australia, Northam to Mullewa line, and reclas ...
