The first step we are going to take is to determine the etymological origin of the term railroad that now concerns us. Specifically, we have to say that it emanates from Latin, since it is the result of the sum of two words of that language:
• "Ferrum", which can be translated as "iron".
• “Carrus”, which was used to refer to any “wheeled vehicle”.
The via created from two lanes arranged in parallel that allow the filming of a train receives the name of railway . The material used to create these lanes is usually the iron ; hence the name of the railroad.
The concept is not only used to name the rail road, but also used to refer to the train (the middle of transport which is formed with several wagons dragged by a locomotive) and to the infrastructure and equipment that allow the development of this means of locomotion.
For example: "The creation of an extensive rail network was very important for the local economy, since it allowed the export of numerous products", "Excuse me, does the railroad reach Puerto San Juan?", “My grandfather came to this country to work on the railroad”.
Throughout history there have been various events that have been fundamental for the development and improvement of the railway. Among those we could highlight the following:
• Year 1550: they begin to establish what were the wooden rails in the narrow-gauge railways that are used in the mines.
• Year 1768: the first iron rail is manufactured.
• Year 1769: Scottish engineer and inventor James Watt patents the steam locomotive.
• Year 1830: the inauguration of the first interurban railway line takes place. Specifically it was Liverpool and Manchester.
• Year 1857: the first steel rails begin to be manufactured.
• Year 1883: the first railway with electricity supply on the track begins to operate. It was an Irish tram, which connected Giant's Causeway and Portrush.
• Year 1964: the first high-speed rail line is inaugurated. It was launched in Japan and responded to the name of Shinkansen.
As a transportation system, the railroad is one of the most popular options worldwide. Unlike bus or the bus , the railway does not cause major damage to environment . The fuel you consume is reduced, as are your polluting emissions.
The railway, on the other hand, has the ability to transport a large number of people on the same trip, since the succession of wagons It confers a good capacity. This makes it usually economical and ecological (it moves many people in the same movement).
The development of the railroad within large cities, however, involves certain risks. It is known as level crossing to the intersection between a road that runs a train and a path (road, route, street, etc.). Although security systems are used as barriers , lights or signals To regulate the passage and prevent collisions, the fluid traffic of vehicles makes accidents quite frequent.
It should be noted that there is also the so-called suburban railway in cities. It is a term that is used to refer to the subway, that other train that runs underground and that allows to communicate quickly and directly different corners of the same population.
