Abstract. Light rail vehicles (LRVs) have historically sourced power from overhead power lines. However, in recent years, catenary-free operations are fast gaining prominence. Catenary-free refers to the removal of the overhead power line equipments from the vehicle system. Power for such systems is sourced on-board energy storage

Currently, lithium batteries are characterized by higher energy density but they require an accurate charge and discharge profile to increase its lifetime, and it is not easily to be obtained feeding urban railway systems. On the other hand, supercapacitors are powerful components, which can deliver very high power pulse for both traction and braking
In this paper, a decoupled model of a train including an on-board hybrid accumulation system is presented to be used in DC traction networks. The train and the accumulation system behavior are modeled separately, and the results are then combined in order to study the effect of the whole system on the traction electrical network. The
