Like mainline trains in Italy but unusual for a metro, trains use 3000 V DC overhead wires for power, the exact reason for doing so being unknown. It is the only metro outside Brazil to use 3000 V DC overhead power, and only of only two metros worldwide to use 3000 V DC power on standard gauge tracks, the other being the
Salvador Metro in Brazil. Belo Horizonte and Porto Alegre use the same voltage too, but on tracks.
