The invention relates to a pre-charging circuit and a road-guided motor vehicle. The invention relates to a pre-charging circuit (10) for an intermediate circuit capacitor (C) of an electrical drive system with a voltage supply from overhead lines (11, 12), the pre-charging circuit (10) having at least one resistor (R), at least two switching elements (5, 6) and has two voltage measuring devices, the first voltage measuring device (13) being arranged between the switching elements and current collectors (1, 2) for the overhead lines (11, 12) and the second voltage measuring device (14) being arranged parallel to the intermediate circuit capacitor (C), wherein the resistor can be switched on or bridged by at least one switching element (5, 7, 21, 22), at least one control unit (15) is associated with the switching element, the control unit is designed in such a way that the at least one resistor is automatically switched on or its bridging is switched off when the voltage (U1) of the first voltage voltage measuring device is below a first threshold value (Ux).
