In view of the experience of the Lotschberg Railway,it has been definitely decided to use the single-phase sys-tem. Even if 7500 volts were reserved eventually forthe Gotthard line, 15,000 volts could be adopted for therest of the federal lines, where tunnels are less choice of system is most significant because what-.
