Abstract: An assembly includes a locomotive, equipped with a roof line, electrically connected to a pantograph, a control system and a sensing circuit. The control system orders, depending on the voltage on the roof line detected by the sensing circuit, the open or closed state of a switch between the roof line and a power supply circuit of the motors of the locomotive. The assembly also includes a tender, coupled to the locomotive and carrying batteries suitable for delivering a current for supplying the motors. The tender is electrically connected to the locomotive in such a way that a first terminal of the batteries is connected to the roof line and a second terminal of the batteries is connected to a point of the locomotive set to a reference potential.
