The aim of this project was to develop a decision making support tool for railway and infrastructure operators to optimize the electricity consumption of the system. To address the objective a software capable of simulating a complete rail network in terms of energy consumption was developed. This software would be able to give a response to the following questions: Which electricity supply contract is more suitable?, Which driving method reduces electricity consumption while maintaining the quality of service?, What return time does it have to have in order to introduce an ATP or a converter change?
