Trains






Train


A train is a mean of transport that circulates by means of mechanical means along of route designed for him. The railroad can go for rails, cables or other routes. They can have locomotive, one or several, being able to be at the top and other one at the tail and coaches, or to be auto rails. In this case the coaches are self-propelled.
The first routes were rails of wood fixed to other chunks of wood.
The coaches ran on wheels of wood.


The first trains of this type, which were pulled by horses were used by the first time in the North-East of England, where they were serving for the load of coal from the local mines to them you grind of a few rivers.







Richard Trevichick was the inventor of this one. With the idea of moving wheels on rails with the energy of the steam. His development of three years led it to trying his invention in 1804 when one of his locomotives dragged 5 coaches loaded during approximately 15 km on an approximate speed of 8 km per hour, in the south of Gales.
George Stephenson benefited from the development of this invention, and was capable of constructing a locomotive that was working adequately. On September 17, 1825, one of his locomotives dragged 38 coaches to speeds that ranged between 20 and 25 km per hour. For the first time, an alternative transport was overcoming the speed of the gallop of the horse.



The first public railroad of the world, in the North-East of England, was inaugurated in 1825 and it was transporting only load. The first public railroad for the transport of passengers and of load that was working exclusively with steam locomotives was that of Liverpool - Manchester, inaugurated in 1830. The 2 projects were directed by George Stephenson.
