Manila Railroad 45 Class
The Manila Railroad 45 class of 1919 were twenty-one ''Ten-wheeler'' steam locomotives. Twenty locomotives were built by American light duty locomotive manufacturer H.K. Porter, Inc. between 1919 and 1921 for the Manila Railroad Company (MRR). The so-called ''Porters'' were the most successful steam locomotive class in Philippine service. They carried express trains for passengers as well as short-range maintenance trains for 70 years and served both the MRR and its successor, the Philippine National Railways. However, like all tender engines from the Manila Railroad era, the last locomotive was scrapped in the 1990s without a single unit preserved. Background The 45 class was intended as a continuation of the 37 class of tender locomotives, both known to the British as the ''D''-class, following the ''A/B/C'' subclasses of the ''Dagupan'' class of tank locomotives. Eight units of the D/37 class were built by Kerr, Stuart and Company in 1906 and were delivered to then-Manila Rai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rain
Rain is a form of precipitation where water drop (liquid), droplets that have condensation, condensed from Water vapor#In Earth's atmosphere, atmospheric water vapor fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectricity, hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convection, convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and ...

Railway Locomotives Introduced In 1919
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in railway track, tracks, which usually consist of two parallel steel railway track, rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and rail freight transport, freight transport globally, thanks to its Energy efficiency in transport, energy efficiency and potentially high-speed rail, high speed.Rolling stock on rails generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by Diesel locomotive, diesel or Electric locomotive, electric locomotives. While railway transport is capital intensity, capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety.

3 Ft 6 In Gauge Locomotives
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th c ...

Steam Locomotives Of The Philippines
Steam is water vapor, often mixed with air or an aerosol of liquid water droplets. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Saturated or superheated steam is invisible; however, wet steam, a visible mist or aerosol of water droplets, is often referred to as "steam". When liquid water becomes steam, it increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapour pressure, it can create a steam explosion. Types of steam and conversions Steam is trad ...

War Film
War film is a film genre concerned with warfare, typically about navy, naval, air force, air, or army, land battles, with combat scenes central to the drama. It has been strongly associated with the 20th century. The fateful nature of battle scenes means that war films often end with them. Themes explored include combat, survival and escape, camaraderie between soldiers, sacrifice, the futility and inhumanity of battle, the effects of war on society, and the moral and human issues raised by war. War films are often categorized by their milieu, such as the Korean War; the most popular subjects are the World War II, Second World War and the American Civil War. The stories told may be fiction, historical drama, or biographical. Critics have noted similarities between the Western (genre), Western and the war film. Nations such as China, Indonesia, Japan, and Russia have their own traditions of war film, centred on their own revolutionary wars but taking varied forms, from action an ...

International Union Of Railways
The International Union of Railways (, UIC) is an international rail transport industry body based in Paris. History The railways of Europe had originated during the nineteenth century as many separate concerns across numerous nations; this led to disparate and conflicting standards emerging and thus onto incompatibility. One prominent example was the British Gauge War, during which different rail transport, railway companies were laying different track gauges across Great Britain, causing inefficiency wherever a break of gauge occurred, prior to an Regulating the Gauge of Railways Act 1846, Act of Parliament the issue in 1846 by establishing one standard gauge of . The early effort towards standardisation somewhat influenced railways aboard as well, however various other track gauges persisted and developed across the world; even through to the twenty first century, incompatible track gauges, let alone other issues, persisted to hinder interoperability efforts.

Railway Coupling
A coupling or coupler is a mechanism, typically located at each end of a rolling stock, rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train. Throughout the history of rail vehicles, a variety of coupler designs and types have been developed worldwide. Key design considerations include strength, reliability, easy and efficient handling, and operator safety. Automatic couplers engage automatically when the cars are pushed together. Modern versions not only provide a mechanical connection, but can also couple brake lines and data lines. Different countries use different types of couplers. While North American railroads and China use Janney couplers, railroads in the former Soviet Union use SA3 couplers and the European countries use Scharfenberg coupler, Scharfenberg and Buffers and chain coupler, screw ...

Buffers And Chain Coupler
Buffers and chain couplers (or couplings) – also known as "buffers and screw", "screw", and "screwlink" – are the de facto International Union of Railways (UIC) standard railway coupling used in the EU and UK, and on some railways in other parts of the world, such as in South America and India, on older rolling stock. Buffers and chain couplers are an assembly of several devices: buffers, hooks and links, or turnbuckle screws. On the modern version of the couplers, rail vehicles are mated by manually connecting the end link of one chain which incorporates a turnbuckle screw into the towing hook of the other wagon, drawing together and slightly compressing the Buffer (rail transport), buffer pairs, one left and one right on each headstock. That limits slack, and lessens Shunting (rail), shunting shocks in moving trains. By contrast, vehicles fitted with the semi-automatic Janney coupler, Janney Type E coupler can experience significant jarring during mating and shunting. V ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its Electricity generation, electricity. Some iron and steel-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train Driver
A train driver is a person who operates a train, railcar, or other rail transport vehicle. The driver is in charge of and is responsible for the mechanical operation of the train, train speed, and all of the train handling (also known as brake handling). Train drivers must follow certain guidelines for driving a train safely. Naming British English terms for a train driver include engine driver, engineman, and locomotive driver. The term in North American English is railroad engineer, but the simpler term engineer is more commonly used. Terms for a train driver in other English dialects include locomotive handler, locomotive engineer, locomotive operator, train operator, and motorman. In American English, a hostler (also known as a switcher) moves engines around rail yards, but does not take them out on the main line tracks; the British English equivalent is a shunter.
