The French term train came to our language like train The concept mentions a means of transport formed by a series of wagons that, dragged by a locomotive , move on tracks (composed, in turn, by the so-called rails or rails ).
This is the definition of train in its broadest or most general sense: at present, it is possible to recognize trains that have different characteristics than those mentioned. There are, for example, trains that levitate Thanks to the action of powerful magnets. There are also trains whose wagons have self propel and thus dispense with the locomotive.
Most trains, however, still appeal to the locomotive for the traction . A locomotive is a vehicle that, through diesel oil , electricity or another source of energy, move along the track and drag the train cars, which are linked together.
The trains have different scopes and ends. In big cities, there are urban or metropolitan trains They make several stops at stations located throughout the town. The long distance trains , instead, they allow to reach different cities and even countries . There are, on the other hand, passenger trains (that move people) and freight trains (intended for the transport of goods).
Many transport experts highlight the advantages of the train compared to other means of locomotion. The train spends less Energy and generates less contamination than the plane or the car to transport the same amount of people. It is also considered a very safe means of transport.
The evolution of the train is certainly one of the most attracted by the public, mainly because it is the first land vehicle that did not require the force of a animal for its funtionability; in other words, it was the first autonomous device for transport , and this makes it the spiritual ancestor of all current media.
It is important to note that the first railway to steam It was presented in 1825, and was used to connect Darlington and Stockton, two towns in England. One of the data that makes his invention more interesting is that it was born from the combination between revolutionary inventions and the observation of other fields: the steam engine dates from the 17th century, almost two hundred years before, and the rail was already used in the field of mining.
At present, the different forms and characteristics that a train can adopt continue to feed the mysticism of this fascinating means of transport. In Mauritania, for example, is the longest in the world: it is about two hundred cars driven by three locomotives , with a total length of four kilometers. This colossus of the tracks is so heavy that it takes several minutes to stop completely. As expected, the speed It is not his forte: it does not exceed 40 km / h.
Just cross the Mediterranean Sea to meet a peculiar hanging train ; It is located in Rhineland, Germany, and its name is Wuppertal's Schwebebahn. Despite being unique in its continent, it is not very popular worldwide. However, in his city It is an emblem, and has been operating since the early twentieth century, passing over urbanizations and rivers.
Crossing the snow is especially difficult for us and our machines; And the train is no exception. Already in the year 1869, the first was created in the United States rack train , characterized by having three rails, one of them serrated. That allows movement in slopes greater than 8%. An example of this technology is the Jungfraujoch, which exceeds 3,000 meters high in its tour of the Swiss Alps.
