A tram called progress

In Zaragoza already enjoy the advantages of this highly efficient tram thanks to the Kers system.


A young Spanish talent, Isaac Prada, a former racing engineer and winner of the Altan Enginering Academy award, participated in the creation of the F1® Kers system that incorporates this innovative train to store energy at each braking and reuse it when it returns to boot. This reduces pollution and saves energy.
