This dissertation aims to establish indicators for the evaluation of the environmental performance of the railway operations, as well as to establish a hierarchy among them regarding their importance given by specialists in the transportation and environment areas. A survey was carried out through a questionary that was applied to these specialists who gave scores, in a 0 to 10 scale, to 25 indicators. Descriptive Statistics and the Factor Analysis Method were used in the analysis of the answers and the establishment of a hierarchy among the indicators. In average, the indicator Accidents involving dangerous products of classes 1 to 4 received the highest importance, while the indicator unitized cargo that falls over the railway line was considered of no importance. With the help of the SPSS 8.0 software, factors were extracted from groups of indicators according to their degree of interrelation. The first factor, which presented the highest interrelation, gathers indicators related to the emission of noise, gases, and particulates along the railway. The used methodology may help the elaboration of Reference and Railways Environmental Management Systems.
