Abstract:

Over the years, due to traffic, environmental problems associated with fossil fuels and related economic problems, the demand for urban rail transit system such as trams, light rail systems and metro has increasing rapidly not only in our country but also all over the world. Since rail public transportation systems require high power, the energy efficiency of the railway system is of great importance. The energy consumption on tram lines is different. Therefore, the factors affecting electricity consumption of trams and metro, especially in metropolitan cities should be examined carefully and the new methods for enhancing energy efficiency of the rail transportation systems should be developed. In this study, tests including different driving styles were carried out for 2 CNR railway vehicles owned by SAMULAŞ A.Ş., which serve in the urban public transportation system in Samsun. The test results were analyzed in terms of traction power and relationship between energy consumption and vehicle weight using the Concerto Maintenance program. The simulation results showed that 20% energy saving was achieved by using the suggested driving scenarios, compared to practical driving at similar vehicle weight. For example, an average of 14 million kWh of energy is consumed annually for rail public transportation systems in Samsun. For this reason, it is thought that the findings obtained in this study will contribute to the reduction of energy consumption of urban rail systems in Turkey.
