The supply station comprises an electric power source 6 at a voltage lower than a desired catenary voltage, said electric power source being connected to a transformer 5 which is arranged to connect an auxiliary feeding line 3 to a catenary 1. The power source 6 may comprise a public grid, a DC-linked frequency and phase converter, an AC generator, a reactive power source such as a shunt capacitor, or an energy storage means. |
