The increasing necessity for sustainable transportation underscores the importance of implementation and optimization of the railway sector, one of the most efficient and low-emission modes of transport. This thesis focuses on the Eco-Drive Mode, which represent an energy optimization strategy for electric trains, applied on intercity trains. The strategy entails adjusting the number of active motors to match the power demand of the train, taking into account the route morphology, the speed limits and the stops. This enhances energy efficiency by enabling electrical components to operate under nominal load, thereby reducing energy consumption by approximately 3-4%. The implementation of this optimization does not necessitate hardware modification; rather, it is carried out through the utilization of the Eco-Drive tool, which evaluates the optimal motors configuration in all scenarios.
