The invention provides a method and device for judging the running state of a train, and relates to the technical field of rail transit, and the method comprises the steps: obtaining an acceleration value sensed by an accelerometer, a first train speed value sensed by an axle speed sensor, and a second train speed value sensed by a Doppler radar; performing differential calculation on the acceleration value to obtain an acceleration change rate value; and based on the change trend of the acceleration value, the change trend of the acceleration change rate value, the change trend of the first train speed value and the change trend of the second train speed value, the running state of the train is judged. The accuracy of judging the running state of the train is improved.
