Innovative Train Technologies Energy Comparison on One Non Electrified Railway

This paper compare the energy performance of several railway traction technologies. After validating the powertrain model of a regional diesel train with experimental measurements, an energy comparison of different green technologies is carried out: hybrid diesel train, battery train and fuel cell train. This initial analysis shows that hybridization, for example, allows energy savings of up to 20% on the nonelectrified track studied, while battery traction alone saves up to 70%. This study is a first step in choosing the use of a green technology, which must be carried out in accordance with a territorial context. The economic aspects, the infrastructure needed and the operating requirements of the railway equipment will have to be integrated in a future study.
