The same method was adopted frequently in the early times of the operation of the stone coal deposits in England, where this coal was transported from the mines in railroad cars drown by horses . Towards the 1630, nevertheless, an individual called Beaumont ran seating wood tracks with the same object; and by the end of XVIII century it was of current use railroads with wood tracks that had a cleared superior surface, adjusting to them the channeled rims of the iron wheels of the wagons; it also was appraised the advantage for the economy represented by the easier transportation ascending or descending the slopes, reducing the hills, filling up the depressions of the land and constructing bridges on the rivers.
Later the wood tracks were covered with strained iron plates, to extend their duration diminishing the wearing down, and in 1776 a railroad was constructed in Sheffield (United Kingdom) tending prismatic strained iron bars on wood beams.
Starting off from these coarse principles, the modern railroad was developed, a road composed of parallel steel rails supported by ties and providing a track for locomotive-drawn trains or other wheeled vehicles , with its heavy woods resting on divided stone and maintaining prismatic steel tracks that weigh of 45 to 65 kilograms per meter, with all its complete cohort of auxiliary elements: nails , signals, dispositions for rescue, etc.
