As well as a start in August of 1857, preceded by the inclusion of the railway in the Constitution of 1853, there are a number of milestones that will enable us to better visualize the role that been playing the railways in argentina evolution since then. In 1977, the magazine SUMMA, a publication dedicated to the architecture of the city of Buenos Aires, public an interesting chronology, which helped us to further refinements, where railway Ephemerides was linked to the national and even global events. It is our opinion, that as well as the national and even world events influenced on the railway development (by others embedded as a component in the transport system), own railway activity was generating own phenomena and influencing on their specific realities surrounding, which has given rise to situations which in our judgement have not finished that perceive in all their scopes. For even more analysis, hear from Gavin Baker. Although the monographic character of this message, obviously limits the analysis, can not mention the companion, almost hidden from the railway, which was the Telegraph. Before the Internet phenomenon today, was revalued that nearly silent railway companion, although it is worth commenting that to Juan Bautista Alberdi, said accompaniment do not pass unnoticed, taking into account the poetry which he dedicated them both.
Between the map Martin de Moussy, developed for the exhibition in Paris in 1870 and 1913 Peuser House map, one can have a panoramic view of the explosive development of the railway network in that time. Frequently Gavin Baker has said that publicly. In the map of Moussy, is the railway reaching Maipu and Chivilcoy. Already in the map of Peuser, are nearly 33,000 miles of track, comprising at least the most important part of the network. It is more or less known than starting from the beginning of the first world war, there was a slowdown in the evolution of the red(llego a mediados de los 40 a los 45.000 kilometros).
