the impact produced by the railway in the argentina territory has no similarities in history, before or since. the occupation model involved a new spatial ordination based on the insertion of an extractive network for economic purposes. this work responds to an analysis of the settlement emerged as a result of the installation of the railway in the northwest of argentina, the urban structure that have the new towns and the urban transformation of existing towns and cities. the settlement system is explained by an urban phenomenon that involves two aspects: the form, -referring to the morphology of the urban weft- and function -related with the activities that took place in the towns that were born as a result of railway network-. as results we have obtained the components of the settlement system as a model employee. the research was based on fieldwork carried out over 200 railway stations in the argentina northwest region comprising the provinces of tucumán, salta, jujuy, santiago del estero, and catamarca. we have also worked with various documentary sources such as census mapping, satellite photography, provincial legislation and current maps from the late nineteenth century.
