A railway vehicle driving device includes a first power converter 1 for driving a three-phase motor 3 by converting DC power input from overhead wiring 2 into three-phase AC power. A power storage device 7 is installed on the vehicle and is capable of charging and discharging DC power. A second power converter 4 controls the current flowing between the power storage device and the first electric power converter and is characterized in that while the first electric power converter is in a power running operation or a regenerative operation, the second electric power converter switches an operation mode of the power storage device to at least two or more operation modes among three operation modes: a charging mode, a discharge mode, and a stop mode, depending on least one of a voltage of the overhead wiring and an input voltage of the first electric power converter.
