Hump Shunting
A classification yard (American and Canadian English (Canadian National Railway use)), marshalling yard (British, Hong Kong, Indian, Australian, and Canadian English (Canadian Pacific Railway use)) or shunting yard (Central Europe) is a railway yard found at some freight train stations, used to separate railway cars onto one of several tracks. First the cars are taken to a track, sometimes called a ''lead'' or a ''drill''. From there the cars are sent through a series of switches called a ''ladder'' onto the classification tracks. Larger yards tend to put the lead on an artificially built hill called a ''hump'' to use the force of gravity to propel the cars through the ladder. Freight trains that consist of isolated cars must be made into trains and divided according to their destinations. Thus the cars must be shunted several times along their route in contrast to a unit train, which carries, for example, cars from the plant to a port, or coal from a mine to the power plant. T ...

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 elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and 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) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. 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. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Readville (MBTA Station)

It is served by MBTA Commuter Rail Fairmount Line and Franklin Line. Readville is the outer terminus for most Fairmount service, though some trips continue as Franklin Line trains. The station is located at a multi-level junction, with the Northeast Corridor tracks at ground level and the Dorchester Branch (used by the Fairmount Line) above; Franklin lines use a connecting track with a separate platform. Platforms are available for the Providence/Stoughton Line on the Northeast Corridor tracks, but they are not regularly used. An MBTA maintenance and storage yard and a CSX Transportation freight yard are located near the station. Passenger service to Dedham Low Plain began in 1834 with the Boston and Providence Railroad (B&P). A branch line to Dedham was built in 1835, and the neighborhood and stat ...

Zawiercie
Zawiercie is a city in the south of Poland located in the Silesian Voivodeship with 49,334 inhabitants (2019). It is situated in the Kraków-Częstochowa Upland near the source of the Warta River. The town lies near the historical region of Silesia, but belongs to Lesser Poland. Name and location Zawiercie, even though currently associated with Silesia, belongs to Lesser Poland. The city lies near the source of the Warta river, and its name probably comes from the location. The inhabitants of the ancient village of Kromołów, to reach another village located on the other side of the river, would go ''behind the Warta'', or in Polish - ''za Wartę''. From the perspective of Kromołów, Zawiercie is located behind the Warta. There is also a theory that the name of the city comes from settlers who ''zawiercili'' (or circled) the settlement area. The town is a gateway to the Polish Jura, where several castles, which used to defend western border of Lesser Poland, are located. Zaw ...

Gravity Yard
A classification yard (American and Canadian English (Canadian National Railway use)), marshalling yard (British, Hong Kong, Indian, Australian, and Canadian English (Canadian Pacific Railway use)) or shunting yard (Central Europe) is a railway yard found at some freight train stations, used to separate railway cars onto one of several tracks. First the cars are taken to a track, sometimes called a ''lead'' or a ''drill''. From there the cars are sent through a series of switches called a ''ladder'' onto the classification tracks. Larger yards tend to put the lead on an artificially built hill called a ''hump'' to use the force of gravity to propel the cars through the ladder. Freight trains that consist of isolated cars must be made into trains and divided according to their destinations. Thus the cars must be shunted several times along their route in contrast to a unit train, which carries, for example, cars from the plant to a port, or coal from a mine to the power plant. ...

Categorization
Categorization is the ability and activity of recognizing shared features or similarities between the elements of the experience of the world (such as Object (philosophy), objects, events, or ideas), organizing and classifying experience by associating them to a more abstract group (that is, a category, class, or type), on the basis of their traits, features, similarities or other criteria that are Universal (metaphysics), universal to the group. Categorization is considered one of the most fundamental cognitive abilities, and as such it is studied particularly by psychology and cognitive linguistics. Categorization is sometimes considered synonymous with classification (cf., Classification (general theory)#Synonyms and near-synonyms, Classification synonyms). Categorization and classification allow humans to organize things, objects, and ideas that exist around them and simplify their understanding of the world. Categorization is something that humans and other organisms ''do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
