This report analyses the use of geosynthetics in railways for subgrade reinforcement and separation of the track layers. Cases of instrumented test sections were studied. These test sections were located in Australia (with geocomposite applications), Brazil (with geotextile and geodrid applications) and China (with geotextile and geodrid applications). Railway design methods using geosynthetics applications were analyzed as well. Based on a studied case for implementation of geosynthetics in a German railway, a railway track was simulated with and without the use of geosynthetics, respectively on PLAXIS v.8 and FERROVIA 3.0 softwares. The performance benefits of the geosynthetics applications in railways were, therefore, confirmed, based on the simulation results

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.
