In a world where the change towards the use of green energy is increasingly current, mobility must also keep pace. For this reason, Alstom is developing a new type of products based on technological innovation in the energy sector. Among these new products there is the FNM-HMU project. It is an electric train belonging to the Coradia Stream family, intended for Gruppo FNM SpA’s regional railway services for the Brescia-Iseo-Edolo line. The energy necessary for the locomotion of this innovative vehicle is provided by the combined application of fuel cells and electric batteries. This is done to guarantee operability on a non-electrified line, where Diesel traction vehicles are still used today.
