A DC traction motor control system includes a plurality of motors each configured to couple with a different axle of a vehicle and rotate the axle to propel the vehicle. The motor is coupled with the direct current bus and is configured to receive direct current via the direct current bus to power the motor. The system also includes a plurality of switch assemblies, each having an H-bridge circuit coupled with a different one of the motors to control rotation of the motor. The system includes a controller configured to transmit a control signal to the switch assembly to individually control the H-bridge circuit to control the torque output by the motor and/or the direction of rotation of the motor.
