The possibility of using series-hybrid vehicle drive-train for railway propulsion has not been considered very frequently yet, mainly because of the larger powers and lifetimes required, with respect to the case of automotive applications. However this possibility is promising in particular cases. In case of small trains, powers of the Electric Generator (EG) of around 150-200kW can be adequate and, if the Internal Combustion Engine (ICE) can be a very low-cost diesel or methane engine of automotive derivation. The Fuel-Cell Storage Subsystem (FCSS) solution also implies practically null emissions into the air and very small noise, that can be a critical factor in some urban environments. If the storage subsystem is adequately dimensioned, the drive-train can operate not only in hybrid mode, in which the two sources of energy (EG and SS) are simultaneously active, but also in pure electric mode, in which the propulsion energy is wholly taken from the storage. A possible application of the proposed solution consists of shunter locomotives, commonly used for both switching and line-haul work, especially suitable to be fitted with hybrid drive-trains, to exploit braking recovery. In the present paper the vehicle behavior under a mixed cycle (with pure-electric and hybrid parts) as well as under pure electric cycle are outlined.
