In 1954, it was celebrated the centenary of railways in Brazil. The date refers to the first section of 14.5 km of railway in Brazil (30/04/1854), in Rio de Janeiro, between Mauá and Fragoso, of the Petropolis Railway Company (Estrada de Ferro Petrópolis). Some of the texts and commemorative events indicated the symbolic values that the railroad took in the Brazilian history. Firstly, on 30.04.1954, the railway section Mauá-Fragoso and steam locomotive “Baroness” (the first used on the track) were declared national monuments(Decree No. 35,447-A, April 30, 1954). Secondly, some entities (Clube de Engenharia, Conselho Nacional de Geografia, Ministério da Viação e Obras Públicas) highlighted the importance of celebrating the Brazilian railway history and its historical significance, economic and geographical. For this, some events was occurred (the commemoration of one hundred years in Rio de Janeiro and Recife on 30.04.1954). Among the texts wrought produced, we highlight the text I Centenary of Brazilian Railroad (1954), released by the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística), and the National Council of Geography (Conselho Nacional de Geografia). The emphasis given to the railway refersto the geographical perspective (territorial expansion), but also makes mention of the Barãode Mauá, the founder of Petropolis Railway Company. We aim to understand the celebration from evocations about the Brazilian railroad history and some ideas that is assigned to the railway (and the Barãode Mauá), and railway heritage (the track and the locomotive “Baroneza”). On basis of this review will seek to understand how it was reconceived the railroad memory in view of these values and material elements.

This paper has as an objetive to present the survey outcomes on the railroad heritage listed by CONDEPHAAT (identification, state of conservation and public politics of use). In one hand, since the 1960s has been formulated the concept of industrial heritage, it would consider the relevance of this concept for the railroad heritage. In the other hand, it is also necessary to understand the concepts that have guided the tipping process of this organ for decades. Anyway, this is to assess the extent to these new concepts of heritage has guided the actions of the São Paulo State Council

This article presents the results of research conducted on full-scale models, studying the behavior of steel sleepers under the action of static loads, in vertical, longitudinal and transverse directions. For the research models were run with rails TR-68, fixed with elastic system on seven sleepers each type, separately, embedded in standard ballast with 35 cm height and on the basis of compacted soil with 30 cm thick. For the load tests were constructed using reaction systems of vertical and horizontal forces with the objective of applying the requests. The system of readings and data acquisition was fully computerized, obtaining in real time the values of forces and displacements. The results were compared with those installed in the same way with sleepers of wood, mono-block and bi-block prestressed concrete. The analyzed results provided unprecedented parameters in Brazil and of great importance for the design of modern railway permanent way, using steel sleepers.
