width

Renfe can breathe calm. The company has a huge business in the Galician corridor. The volume of travelers Between Madrid and Galicia he has shot to the point that airlines are retreating. Time savings since high speed arrives is such that many are choosing to pass to the train due to pure comfort or time flexibility. The Galician corridor is part of the next package of liberalization of the roads, next to the trains with destination Asturias, Cantabria, Cádiz and Huelva. It will not be, at least, until 2028 when the competition is palpable on the tracks because Adif is not complying with the deadlines planned. But Madrid-Galicia has another peculiarity. It is very likely that in 2028 we will see competition on their ways. To find the reason we have to travel to the nineteenth century. The particular Spanish railroad Each new technology arrives with a good rosary of standards of all kinds. It has happened with electric cars and passed with electricity itself. Also with measurement standards or, as in this case, train tracks. The railroad had started in the early nineteenth century. Although the steam machine was already born in the 18th century, it was not until 1804 when Richard Trevithick built A prototype in which the concept applied to transport. The steam locomotive was born. That one of those huge irons with wheels will pull a kind of drawers and could move the goods faster than they had done seemed like a great idea. So great that it soon caught and in 1830 the first train line was opened with passengers. They were the famous 50 kilometers that separated Liverpool from Manchester whose first trip headed George Stephensonwho was the ideologist of the construction of those first route. Those first trains circulated through some roads of 1,422 millimeters, 4 feet and 8 inches. Shortly after, those same ways widen half inch until reaching the famous 1,435 mm. Then they did not know but they had just adopted the “international width”, which is mounted in most trains in the world. Those measures also served to establish Two categories: narrow path (below those 1,435 mm) and wide via (above). The good results of the first trains made the railroad make the leap to continental Europe and the United States. But, like everything in this life, there were those who thought the system could be improved and that it was worth trying. That person was Isambard Kingdom Brunelan excellent British engineer who would create the Great Railroad of the West, joining London with the southwest, western England and much of Wales. Brunel thought that the higher the width of roads, faster speed could reach a train because the greater the stability achieved. Thus, it extended the track width up to 2,140 mm. Then a war of standards began that ended up resolving the Commission of Railroad Widths in favor of Stenphenson and its width of 1,435 mm. It was 1845. In Spain, at that time, we were engaged in the same fight. Railroad yes, but … how? That doubt was the one that set fire in the middle of the 19th century. Observing the good results that were being achieved outside our borders, the Government began to receive requests for the granting of licenses that allowed them to exploit the roads. Aware that it was necessary to harmonize the matter, they consulted a commission of engineers led by Juan Subercase, number one in the Corps of Engineers, acting president of the Advisory Board and director of the School of Engineers since 1837. He was helped Calixto Santa Cruz, number one of his promotion of 1839, and José Subercase, who in addition to his son was also the number one in his promotion the following year, 1840. Together they drafted the report 17.10.1844, on the Madrid Railroad to Cádiz, which recommended to reject a concession to build a railroad from Madrid to Cádiz. This concession was requested by the French engineer Juqueau Galbrun, which was certainly ironic over the years. Explains J. Moreno Fernández in a document in which the whole story of that controversial decision tells that none of the mentioned engineers had left the country and known firsthand how the railroads were abroad. That, perhaps, was one of the reasons why it was omitted that France had opted for international road width. And it is that Subercase was a firm defender of a width of six feet Castilians. The 1,672 millimeters that would end up receiving the name of “Iberian Width”. The defense is that a higher track width forced to use more powerful locomotives. In those days they thought they could increase vaporization with a wider boiler and that this was essential to, in a mountainous country like Spain, to have sufficient power to move the train. They also defended that a higher track width allowed a more stable step per curve but the truth is that time showed that neither one thing nor the other were key. The international width has been versed enough to be used in mountainous areas and the largest boilers in the trains had the problem of increasing the weight so the gain was diluted. In the government they thought that Subarcase motivations They were correct and they didn’t care that in the neighboring country they bet on a narrower track width. To import, they did not care that our other neighbor, Portugal, also promoted their railroads with the international width. In 1844, it was finally decided that the Spanish measure of the six Spanish feet was the one that should be protagonist for its orographic peculiarities. However, that did not condition the government that gave the approval to two routes built on that international width that was quickly imposing. Portugal pressed to have a railway exit to France that Spain ignored. And that created an urban legend that remains until today First in a line between Barcelona and Mataró, projected from the beginning with that exceptional width for the Spaniards … Read more
