FS Class 410
FS Class 410 were steam locomotives which the Italian State Railways (FS) acquired from Rete Sicula (the Sicilian Network) on nationalization in 1906. History The class was designed by the Sicula Network Research Office led by engineer Guglielmo Cappa as part of a renewal and unification programme to replace obsolete rolling stock inherited from the previous management. It was designated as a group F, according to the custom that was then to define with letters the group of locomotives according to their function, and numbered from 301 to 325. When they passed to FS, they were registered as Class 420. They had some technical differences from other FS 0-8-0 locomotives, notably the use of Walschaerts valve gear instead of Stephenson valve gear, Stephenson. They were built in three batches and there were some detail differences between batches. The first unit was ordered from Società Italiana Ernesto Breda, Breda in Milan and delivered in 1892 and a further 21 units came from G ...

Società Italiana Ernesto Breda
Società Italiana Ernesto Breda (), more usually referred to simply as Breda, was an Italian mechanical manufacturing company founded by Ernesto Breda in Milan in 1886. History The firm was founded by Ernesto Breda in Milan in 1886. It originally manufactured locomotives and other railway machinery, but later branched out into armaments and aircraft. Occasionally, not continuously, the company also built trolleybuses. In 1935, it acquired the railway division of Officine Ferroviarie Meridionali and, soon afterwards, the aircraft division of the same company. Breda-designed machine guns such as the Breda Model 30 and Breda Model 37 were standard issue weapons for the Royal Italian Army during the Second Italo-Abyssinian War, the Italian Invasion of Albania and World War 2. At the peak of its wartime production, the company had 26,000 employees. By 1954, its workforce had been reduced to around 8,000. In 1962, Breda was nationalised as part of EFIM, but was liquidated in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saturated Steam
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 i ...

Freight Locomotives
In transportation, cargo refers to goods transported by land, water or air, while freight refers to its conveyance. In economics, freight refers to goods transported at a freight rate for commercial gain. The term cargo is also used in case of goods in the cold-chain, because the perishable inventory is always in transit towards a final end-use, even when it is held in cold storage or other similar climate-controlled facilities, including warehouses. Multi-modal container units, designed as reusable carriers to facilitate unit load handling of the goods contained, are also referred to as cargo, especially by shipping lines and logistics operators. When empty containers are shipped each unit is documented as a cargo and when goods are stored within, the contents are termed containerized cargo. Similarly, aircraft ULD boxes are also documented as cargo, with an associated packing list of the items contained within. Description Marine Seaport terminals handle a wide rang ...

Standard-gauge Locomotives Of Italy
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), international gauge, UIC gauge, uniform gauge, normal gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with about 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, Uzbekistan, and some line sections in Spain. The distance between the inside edges of the heads of the rails is defined to be 1,435 mm except in the United States, Canada, and on some heritage British lines, where it is defined in U.S. customary/ British Imperial units as exactly "four feet eight and one half inches", which is equivalent to 1,435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rail heads) to be used, as the wheels of the rolling stock (locomoti ...

Railway Locomotives Introduced In 1892
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. Precursors of railways driven by human or an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D N2 Locomotives
D, or d, is the fourth Letter (alphabet), letter of the Latin alphabet, used in the English alphabet, modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is English alphabet#Letter names, ''dee'' (pronounced ), plural ''dees''. History The Semitic languages, Semitic letter Daleth, Dāleth may have developed from the logogram for a fish or a door. There are many different Egyptian hieroglyphs that might have inspired this. In Semitic, Ancient Greek and Latin, the letter represented ; in the Etruscan alphabet the letter was archaic but still retained. The equivalent Greek letter is delta, Delta (letter), Δ. The lower case, minuscule (lower-case) form of 'd' consists of a lower-story left Typeface anatomy#Strokes, bowl and a Typeface anatomy#Strokes, stem ascender. It most likely developed by gradual variations on the upper case, majuscule (capital) form 'D', and is now composed as a stem with a full Typeface ...

Footnotes
In publishing, a note is a brief text in which the author comments on the subject and themes of the book and names supporting citations. In the editorial production of books and documents, typographically, a note is usually several lines of text at the bottom of the page, at the end of a chapter, at the end of a volume, or a house-style typographic usage throughout the text. Notes are usually identified with superscript numbers or a symbol.''The Oxford Companion to the English Language'' (1992) p. 709. Footnotes are informational notes located at the foot of the thematically relevant page, whilst endnotes are informational notes published at the end of a chapter, the end of a volume, or the conclusion of a multi-volume book. Unlike footnotes, which require manipulating the page design (text-block and page layouts) to accommodate the additional text, endnotes are advantageous to editorial production because the textual inclusion does not alter the design of the publication.

Slide Valve
The slide valve is a rectilinear valve used to control the admission of steam into and emission of exhaust from the cylinder of a steam engine. Use In the 19th century, most steam locomotives used slide valves to control the flow of steam into and out of the cylinders. In the 20th century, slide valves were gradually superseded by piston valves, particularly in engines using superheated steam. There were two reasons for this: * With piston valves, the steam passages can be made shorter. This reduces resistance to the flow of steam and improves efficiency. * It is difficult to lubricate slide valves adequately in the presence of superheated steam. Murdoch's D slide valve The D slide valve, or more specifically Long D slide valve, is a form of slide valve, invented by William Murdoch and patented in 1799. It is named after the hollow central D-sectioned piston. This valve worked by "connecting the upper and lower valves so as to be worked by one rod or spindle, and in mak ...

Simple Expansion
A compound engine is an engine that has more than one stage for recovering energy from the same working fluid, with the exhaust from the first stage passing through the second stage, and in some cases then on to another subsequent stage or even stages. Originally invented as a means of making steam engines more efficient, the compounding of engines by use of several stages has also been used on internal combustion engines and continues to have niche markets there. The stages of a compound engine may be either of differing or of similar technologies, for example: * In a turbo-compound engine, the exhaust gas from the cylinders passes through a turbine, the two stages being dissimilar. * In a compound steam locomotive, the steam passes from the high-pressure cylinder or cylinders to the low-pressure cylinder or cylinders, the two stages being similar. * In a triple-expansion steam engine, the steam passes through three successive cylinders of increasing size and decreasing pressu ...
