This paper presents some results obtained with an electric railway simulator. This tool has been mainly developed for studying energy consumptiom in both AC and DC electrified railway systems. Two case studies have been carried out. The first one analyzes a DC electrified underground system, assessing the energy saving related with the introduction of trains equipped with regenerative braking, reversible substations, etc. The second case study consists in an AC electrified high speed line where improvements due to the introduction of regenerative braking, capacitor banks and enhanced +25 kV/-75kV electrification are analyzed.
