At first glance, this seemed destined to increase the business of railway undertakings, because at that time, this meant that carts and harnesses, would increase earnings of the companies. That is the origin of the roads which are often seen by the side of the tracks. As virtually the railways gave gain until the beginning of the Decade of the thirties, in that way the railroad, began to fund the infrastructure of the medium, so much prejudice would you cause. Each time that we have the opportunity, share reflections on the railway issue in the country, we tend to, cite a guide of the South communications Americans, published in 1925, which can be found at the National Library of the city of Buenos aires. This guide shows the detail of schedules and routes of trains and Argentine passenger vessels and its connections to South America. By way of curiosity, is there announced a combined service from train and boat, which allowed to go from Buenos Aires to Lima in seven days.

Two years earlier, President Alvear, had issued the decree by which air transport was organized in the country. Stopped reading of the above-mentioned Guide, leads us to think about that, to that date it was composed of the transport system in the country, and all I needed was a constant technological updating. The railway South American congresses of 1910 and 1922, reveal the situation of a medium which in fact constituted a monopoly on land transport. However, poco for after the first world war, linked to the emergence of the United States, as a world power, the automotive industry in this country, began to place their products in the country, which obviously began to circulate on those roads that financed a surplus railroad. In the book my life of rail English in argentina, published by Arturo Coleman, in Bahia Blanca in 1949, this author says that when in the year 1931, Sud rail, paid by last time dividends to its shareholders, of gave account that the hegemonic landscape began to change.
