One of the latest trends in the transport field is the increasing interest for the rejuvenation of the railway. It is considered to be a logical consequence of the gradual switch towards a more sustainable future in transports. Terminals and stations are considered to be the junction points between the various lines that constitute the railway network and can simply be described as points of arrival, departure and interchange of passengers or commodities. The most commonly used indicators that measure the level of their performance are time and cost. This study aims at exploring possible improvements that could be implemented to the infrastructure and the operation of terminals and stations in order to increase the efficiency level. Firstly, drawing upon grounded theory about rail infrastructure and terminals, a description is conducted, followed by a comparative analysis of the different types of existing terminals and stations. Secondly, the suggested improvements are presented in accordance with their time frame completion. The main contribution of this study is to illustrate the high significance of terminals, stations and yards, acknowledging them as crucial parts of the railway network, because as characterized and demonstrated in this study, their performance are key factors to the whole network performance, making the identification of their critical points and respective possible solutions, the final objective of this paper. In addition to this, emphasis is given to the need of improving and developing the existing terminal infrastructure and operations.

Uma das últimas tendências na área de transportes é o crescente interesse na modernização da rede ferroviária. Este passo é considerado como uma consequência lógica da mudança progressiva para um futuro mais sustentável em transportes. São considerados terminais e estações os pontos de convergência entre as várias linhas que constituem a rede ferroviária e podem ser simplesmente descritos como pontos de partida, chegada e circulação de passageiros ou mercadorias. Os indicadores mais comuns utilizados para medir os seus níveis de desempenho são o tempo e o custo. Este estudo pretende explorar possíveis melhorias que podem ser implementadas na infraestrutura e na operação de terminais e estações, a fim de melhorar os seus níveis de eficiência. Em primeiro lugar, e baseando-se na teoria fundamentada nos dados, é feita uma descrição, seguida de uma análise comparativa dos diferentes tipos de terminais e estações existentes. Em segundo lugar, são apresentadas as melhorias sugeridas, de acordo com o seu período de implementação. Tem este estudo como principal contribuição, ilustrar a alta importância dos terminais, estações e pátios, uma vez que estes são considerados como partes fundamentais da rede ferroviária. É também dada grande ênfase à necessidade de melhorar e desenvolver a infraestrutura dos terminais existentes, assim como as operações envolvidas.
