In order to solve the problem of, when the number of self-supply sources within a set train decreases due to a failure or the like and a certain number of drive systems cannot operate, being unable to ensure torque with which a train can be self-propelled and significantly affecting a train operation, this drive control device is provided with: a plurality of power conversion devices comprising a converter for converting a first AC power into a DC power and an inverter for converting the DC power into a second AC power and driving an electric motor; a self-supply source connected to the converter of each of the power conversion devices and supplying the first AC power; and an auxiliary power supply device receiving the supply of the DC power from the DC line of each of arbitrary two power conversion devices via a connection circuit. The auxiliary power supply device has a switching circuit for connecting the DC lines of the respective two power conversion devices and supplies the first AC power supplied by one self-supply source to one or more power conversion devices, the converters of which are not connected to said self-supply source using the connection circuit and the switching circuit.
