The FS Class E.471 locomotives were prototype three-phase AC electric locomotives designed for the Italian State Railways (FS). They constituted the first Italian experiment in using a phase converter. The final goal was to power them with single-phase alternating current, constituting the first case of a European locomotive of this type designed according to modern criteria. However, the difficulty of the development, and political interference, led to the abandonment of the project.
