In this study a light hybrid rail train hydrogen powered is considered and the influence of the payload factor variation on traction energy consumption is investigated. For this purpose, a parametric software has been developed to simulate the train running over a railway path by varying the payload factor. As simulated system, an existing non-electrified single-track line has been taken into consideration and the traction energy requirement has been evaluated as function of the pay load factor. The specific fuel consumptions of a similar Diesel train have been compared under the same operating conditions. The results highlight that a significant fuel saving to be achieved.

Abstract
In this study a light hybrid rail train hydrogen powered is considered and the influence of the payload factor variation on traction energy consumption is investigated. For this purpose, a parametric software has been developed to simulate the train running over a railway path by varying the payload factor. As simulated system, an existing non-electrified single-track line has been taken into consideration and the traction energy requirement has been evaluated as function of the pay load factor. The specific fuel consumptions of a similar Diesel train have been compared under the same operating conditions. The results highlight that a significant fuel saving to be achieved.Pubblicazioni consigliate
