Victorian Railways V Class
The Victorian Railways V Class is a steam locomotive, used on the Victorian Railways in the period 1900-1930. History and Description In 1899, the Victorian Railways (VR) imported from the Baldwin Locomotive Works, Philadelphia, USA, a pattern locomotive for a new design of all-lines heavy goods engine. It was the largest that the VR system had operated up to then, and was typically American in design. It had a 2-8-0 ("Consolidation") wheel arrangement, with four cylinders arranged according to the Vauclain compound system of propulsion. The maker's number was 17396 and the pattern locomotive entered service on 30 May 1900 as V Class number 499. Test runs were made with coal trains between Melbourne and Nyora in South Gippsland, where the locomotive quickly demonstrated its worth. It also made a test run to Upper Ferntree Gully, where damage was caused to the cleading and lagging of the low-pressure cylinder, due to it striking the platform, which in those days had an insid ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Canadian Pacific Railway
The Canadian Pacific Railway (french: Chemin de fer Canadien Pacifique) , also known simply as CPR or Canadian Pacific and formerly as CP Rail (1968–1996), is a Canadian Class I railway incorporated in 1881. The railway is owned by Canadian Pacific Railway Limited, which began operations as legal owner in a corporate restructuring in 2001. Headquartered in Calgary, Alberta, the railway owns approximately of track in seven provinces of Canada and into the United States, stretching from Montreal to Vancouver, and as far north as Edmonton. Its rail network also serves Minneapolis–St. Paul, Milwaukee, Detroit, Chicago, and Albany, New York, in the United States. The railway was first built between eastern Canada and British Columbia between 1881 and 1885 (connecting with Ottawa Valley and Georgian Bay area lines built earlier), fulfilling a commitment extended to British Columbia when it entered Confederation in 1871; the CPR was Canada's first transcontinental railway. ...

Victorian Railways C Class
The C class was a mainline goods locomotive of the 2-8-0 'Consolidation' type that ran on the Victorian Railways between 1918 and 1962. Although its original design had some key shortcomings, a number of improvements were made over the class' long career on the VR, many of which were subsequently applied to other locomotive classes on the system. History Designed by Chief Mechanical Engineer W. M. Shannon, the C class was the first goods locomotive designed and built entirely in-house by the Victorian Railways Newport Workshops, following on from the successful Dd and A2 class passenger locomotives. When class leader C 1 was introduced in 1918, it was the heaviest and most powerful steam locomotive in Australia. It had been necessary for Victorian Railways to strengthen bridges at Dudley Street, North Melbourne and along the lines to Woodend and Seymour on which the new locomotive was expected to run. Production The prototype locomotive C 1 was the only one of the cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria (Australia)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolit ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years.

Victorian Railways X Class
The Victorian Railways X class was a mainline goods locomotive of the 2-8-2 'Mikado' type operated by the Victorian Railways (VR) between 1929 and 1960. They were the most powerful goods locomotive on the VR, aside from the single H class, H220, which was confined to the North East line, until the advent of diesel-electric traction, and operated over the key Bendigo, Wodonga, and Gippsland mainlines. History The X class was a development of the earlier C class 2-8-0 goods locomotive, designed to be gauge convertible from to in the event of the Victorian Railways network being converted to standard gauge. The C class, with a narrow firebox between the frames, could not be easily converted. The X class retained the same cylinder and driving wheel dimensions as the C class as well as its valve gear, but introduced a much larger boiler and a trailing truck behind the rear driving axle. The 2-8-2 layout of the X class allowed a wide, deep firebox suited to the high ash, low ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ratchet (device)
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ''ratchet'' is also used informally to refer to a ratcheting socket wrench. __TOC__ Theory of operation A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a '' pawl'' (or ''click'', in clocks and watches) that engages the teeth. The teeth are uniform but are usually asymmetrical, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e. forward) direction, the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing it (often with an audible 'click') into the depression between the teeth as it passes the tip of each tooth. When the teeth move in the opposite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johnson Bar (locomotive)
A Johnson Bar is a control lever on a steam locomotive, used to control the timing of the admission of steam into the locomotive's cylinders. By controlling this timing, the amount of power delivered to the wheels is regulated, as is the direction that the wheels rotate, giving the lever the alternate name of the reversing lever. This is the term employed in British English, while the term 'Johnson Bar' is the norm in the United States. History Historians have not identified the reasons why engineers called the reversing lever a Johnson Bar, but the reversing lever is described in both British, and American railway journals of the time. The best accreditation of the invention is documented under the Walschaerts valve gear. Reversing The reversing lever in locomotive history is documented from about 1842. The American Railway Master Mechanic's Association had members that published illustrations. Parts for the reversing lever are drawn in the "Locomotive Dictionary", 1st e ...

Valve Gear
The valve gear of a steam engine is the mechanism that operates the inlet and exhaust valves to admit steam into the cylinder and allow exhaust steam to escape, respectively, at the correct points in the cycle. It can also serve as a reversing gear. It is sometimes referred to as the "motion". Purpose In the simple case, this can be a relatively simple task as in the internal combustion engine in which the valves always open and close at the same points. This is not the ideal arrangement for a steam engine, though, because greatest power is achieved by keeping the inlet valve open throughout the power stroke (thus having full boiler pressure, minus transmission losses, against the piston throughout the stroke) while peak efficiency is achieved by only having the inlet valve open for a short time and then letting the steam expand in the cylinder (expansive working). The point at which steam stops being admitted to the cylinder is known as the '' cutoff'', and the optimal positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spark Arrestor
A spark arrester (sometimes spark arrestor) is any device which prevents the emission of flammable debris from combustion sources, such as internal combustion engines, fireplaces, and wood burning stoves. Spark arresters play a critical role in the prevention of wildland fire and ignition of explosive atmospheres. Consequently, their use is required by law in many jurisdictions worldwide. Applications Engines Steam Spark arresters for steam locomotives may be internal (in the form of wire mesh inside the smokebox) or external. The earliest platforms for spark arresters in the United States were steam locomotives. Wood- and coal-burning locomotives produce embers which are readily transported by the wind. One popular design was the Radley-Hunter spark arrester, which used a spiral-shaped cone to separate embers from the exhaust flow by centrifugal force. The problem of equipment-started fires continued into the 20th century. University of California, Berkeley researchers J.P ...

Smokebox
A smokebox is one of the major basic parts of a steam locomotive exhaust system. Smoke and hot gases pass from the firebox through tubes where they pass heat to the surrounding water in the boiler. The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney (or funnel). Early locomotives had no smokebox and relied on a long chimney to provide natural draught for the fire but smokeboxes were soon included in the design for two specific reasons. Firstly and most importantly, the blast of exhaust steam from the cylinders, when directed upwards through an airtight smokebox with an appropriate design of exhaust nozzle, effectively draws hot gases through the boiler tubes and flues and, consequently, fresh combustion air into the firebox. Secondly, the smokebox provides a convenient collection point for ash and cinders ("char") drawn through the boiler tubes, which can be easily cleaned out at the end of a working day. Without a smokebox, all char must ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-tube Boiler
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer far greater heating surface area for the same overall boiler volume. The general construction is as a tank of water penetrated by tubes that carry the hot flue gases from the fire. The tank is usually cylindrical for the most part—being the strongest practical shape for a pressurized container—and this cylindrical tank may be either horizontal or vertic ...
