Urban rail systems among the public transport types are increasingly preferred due to the use of more convenient, reliable, clean energy and resulting in less air pollution, higher carrying capacity and faster accessibility. In contrast to all these positive features, the urban rail systems require highly costly investments and therefore the planning and implementation must be carried out in the best possible way. In this study, an evaluation was made by comparing the performances of urban rail transportation systems operated in Turkey with Data Envelopment Analysis. The data is collected from the Transportation Department Presidency and related literature for this study. As a result of the implementation, the recommendation for the efficiency value of each city's rail transportation system and the recommended improvement for the ineffective cities are presented.
