A railway vehicle on which a rotary electric machine is mounted, the railway vehicle comprising, in order to detect slip or slide in an early stage while stabilizing a control system even at the time of slip or slide: a voltage output device for outputting a drive voltage to the rotary electric machine; a current detector for detecting a current flowing through the rotary electric machine; and a control device for estimating and calculating the angular velocity of a rotor of the rotary electric machine. The control device calculates a compensation value for correcting a quantity of state to be used as input for estimating and calculating the angular velocity in order to suppress a steady-state deviation generated in the quantity of state to substantially zero while the rotary electric machine is being accelerated or decelerated, and when the compensation value exceeds a predetermined value, detects the slip or slide of a drive wheel driven by the rotary electric machine.
