Question

essay about train origin

Answer 1

A train is a form of rail transport consisting of a series of vehicles that usually runs along arail track to transport cargo or passengers. Motive power is provided by a separatelocomotive or individual motors in self-propelled multiple units. Although historicallysteam propulsion dominated, the most common modern forms are diesel and electriclocomotives, the latter supplied by overhead wires or additional rails. Other energy sources include horses, engine or water-driven rope or wire winch, gravity, pneumatics, batteries, andgas turbines. Train tracks usually consist of two running rails, sometimes supplemented by additional rails such as electric conducting rails and rack rails, with a limited number ofmonorails and maglev guideways in the mix.[1]The word 'train' comes from the Old Frenchtrahiner, from the Latin trahere 'pull, draw'.[2]

There are various types of trains that are designed for particular purposes. A train may consist of a combination of one or morelocomotives and attached railroad cars, or a self-propelled multiple unit (or occasionally a single or articulated powered coach, called arailcar). The first trains were rope-hauled, gravity powered or pulled by horses. From the early 19th century almost all were powered bysteam locomotives. From the 1910s onwards the steam locomotives began to be replaced by less labor-intensive and cleaner (but more complex and expensive) diesel locomotivesand electric locomotives, while at about the same time self-propelled multiple unitvehicles of either power system became much more common in passenger service.

A passenger train is one which includes passenger-carrying vehicles which can often be very long and fast. One notable and growing long-distance train category is high-speed rail. In order to achieve much faster operation over 500 km/h (310 mph), innovative Maglev technology has been researched for years. In most countries, such as the United Kingdom, the distinction between a tramway and a railway is precise and defined in law. The term light rail is sometimes used for a modern tram system, but it may also mean an intermediate form between a tram and a train, similar to a heavy rail rapid transit system except that it may have level crossings.
