TRAIN

Train

From Wikipedia, the free encyclopedia

A railway or railroad train is a connected series of vehicles for rail transport that move along a track (permanent way) to transport cargo or passengers from one place to another place. The track usually consists of two, three or four rails, but might also be a monorail or maglev guideway.

Propulsion for the train is provided by a separate locomotive, or from individual motors in self-propelled multiple units. Most modern trains are powered by diesel locomotives or by electricity supplied by overhead wires or additional rails, although historically (from the early 19th century to the mid-20th century) the steam locomotive was the dominant form of locomotive power. Other sources of power (such as horses, rope or wire, gravity, pneumatics, batteries, and gas turbines) are possible.

The word 'train' comes from the Old French trahiner, itself from the Latin trahere 'pull, draw'.

Coal

From Wikipedia, the free encyclopedia

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.

Throughout history, coal has been a useful resource for human consumption. It is primarily burned for the production of electricity and or heat, and is also used for industrial purposes such as refining metals. A fossil fuel, coal forms when dead plant matter is converted into peat, which in turn is converted into lignite, then subbituminous coal, after that bituminous, lastly anthracite. This involves biological and geological processes that take place over a long period of time.

Coal is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of carbon dioxide releases. Gross carbon dioxide emissions from coal usage are slightly more than those from petroleum and about double the amount from natural gas. Coal is extracted from the ground by mining, either underground by shaft mining through the seams or in open pits.

Rail transport

The New York City Subway is the world's largest rapid transit system by number of train stations and by length of routes. Built in 1830, Liverpool Road station in Manchester is the oldest surviving railway terminus building in the world.Broad Green station, Liverpool, shown in 1962, built in 1830, is the oldest used station in the world.

Opened in 2006, Berlin Hauptbahnhof is a large station at the crossing point of two major railways and features modern, abstract architecture. Berlin used to have a ring of terminus stations, similar to London and Paris, but these were gradually replaced with through stations over the period of 1882–1952.

A train station, also called a railroad station (mainly in the United States) or railway station (mainly in the British Commonwealth) and often shortened to just station, is a railway facility where trains regularly stop to load or unload passengers or freight. It generally consists of a platform next to the track and a station building (depot) providing related services such as ticket sales and waiting rooms. If a station is on a single track main line, it usually has a passing loop to facilitate the traffic. The smallest stations are referred to as 'stops' or, mainly in the British Commonwealth, 'halts' (flag stops). Connections may be available to intersecting rail lines or other transport modes such as buses or rapid transit systems.
