Running Plate
A footplate provides the structure on which a locomotive driver and fireman stand in the cab to operate a British or continental European steam locomotive. It comprises a large metal plate that rests on top of the locomotive frame, usually it is covered with wooden floorboards. It takes up the full width of the locomotive cab, and in depth it extends from the front of the cab to the coal bunker on the tender. The cab and other superstructure elements are in turn mounted on it. On some locomotives, the footplate is extended beyond the front of the cab to form a walkway around the boiler – usually referred to as the "running board" or "foot board" – to facilitate inspection and maintenance. In Britain, the word remains in use as a synonym for the cab or working in the cab, even in the context of diesel and electric locomotives, as in the expression of working ''on the footplate''. The term can also be applied to the external step along the side of a classical tram. Nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cab (locomotive)
The cab, crew compartment or driver's compartment of a locomotive, or a self-propelled rail vehicle, is the part housing the train driver, fireman or secondman (if any), and the controls necessary for the locomotive or self-propelled rail vehicle's operation. Cab locations On steam locomotives, the cab is normally located to the rear of the firebox, although steam locomotives have sometimes been constructed in a cab forward or camelback configuration. The cab, or crew or driver's compartment of a diesel or electric locomotive will usually be found either inside a cabin attached to a hood unit or cowl unit locomotive, or forming one of the structural elements of a cab unit locomotive. The former arrangement is now the norm in North America for all types of diesel or electric locomotives. In Europe, most modern locomotives are cab units with two cabs, one at each end. However, the locomotives powering some high speed European trains are normally cab units with one cab, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Steam Locomotives Of British Railways
The steam locomotives of British Railways were used by British Railways over the period 1948–1968. The vast majority of these were inherited from its four constituent companies, the " Big Four". In addition, BR built 2,537 steam locomotives in the period 1948–1960, 1,538 to pre-nationalisation designs and 999 to its own standard designs. These locomotives had short working lives, some as little as five years, because of the decision to end the use of steam traction by 1968, against a design life of over 30 years and a theoretical final withdrawal date of between 1990 and 2000. Background British Railways was created on 1 January 1948 principally by the merger of the " Big Four" grouped railway companies: the Great Western Railway (GWR), the London, Midland and Scottish Railway (LMS), the London and North Eastern Railway (LNER) and the Southern Railway (SR). It inherited a wide legacy of locomotives and rolling stock, much of which needed replacing due to the ravages of Wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crewe Works Pilot Geograph-2804155-by-Ben-Brooksbank
Crewe () is a railway town and civil parish in the unitary authority of Cheshire East in Cheshire, England. The Crewe built-up area had a total population of 75,556 in 2011, which also covers parts of the adjacent civil parishes of Willaston, Shavington cum Gresty and Wistaston. Crewe is perhaps best known as a large railway junction and home to Crewe Works; for many years, it was a major railway engineering facility for manufacturing and overhauling locomotives, but now much reduced in size. From 1946 until 2002, it was also the home of Rolls-Royce motor car production. The Pyms Lane factory on the west of the town now exclusively produces Bentley motor cars. Crewe is north of London, south of Manchester city centre, and south of Liverpool city centre. History Medieval The name derives from an Old Welsh word ''criu'', meaning 'weir' or 'crossing'. The earliest record is in the Domesday Book, where it is written as ''Creu''. Modern Until the Grand Junction Railw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firebox (steam Engine)
In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler. Most are somewhat box-shaped, hence the name. The hot gases generated in the firebox are pulled through a rack of tubes running through the boiler. Steam locomotive fire tube firebox In the standard steam locomotive fire-tube boiler, the firebox is surrounded by water space on five sides. The bottom of the firebox is open to atmospheric pressure, but covered by fire grates (solid fuel) or a firing pan (liquid fuel). If the engine burns solid fuel, like wood or coal, there is a grate covering most of the bottom of the firebox to hold the fire. An ashpan, mounted underneath the firebox and below the grates, catches and collects hot embers, ashes, and other solid combustion waste as it falls through the grates. In a coal-burning locomotive, the grates may be shaken to clean dead ash from the bottom of the fire. They are shaken either manually or (in larger locomotiv ...

Tram
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the Unit ...

Running Board
A running board or footboard is a narrow step fitted under the side doors of a tram ( cable car, trolley, or streetcar in North America), car, or truck. It aids entry, especially into high vehicles, and is typical of vintage trams and cars, which had much higher ground clearances than today's vehicles. It is also used as a fashion statement on vehicles that would not otherwise require it. The origin of the name running board is obscure; the first running boards predate automobiles and were installed on carriages as early as the 17th century. History Rail The term also applied to the walkways on top of railway/railroad boxcars. Originally, they were used by brakemen to travel from car to car to apply hand-operated brakes. With the adoption of the air brake this practice was abandoned. However the running board was still used as an observation point to pass hand signals to the train driver (train engineer in North America) when cars were being shunted (switched in No ...

Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...
