A train overspeed protection method includes: acquiring, when emergency braking is triggered for a train, an initial speed limit location point of each speed limit region among a preset number of speed limit regions, and a first speed limit value corresponding to each initial speed limit location point so as to obtain a plurality of first speed limit values; acquiring a current traveling location point of the train and a corresponding second speed limit value, and acquiring a current traveling speed of the train; determining a plurality of decelerations of the current traveling speed relative to each first speed limit value, selecting a deceleration satisfying a preset condition from the plurality of decelerations, and determining the initial speed limit location point corresponding to the deceleration satisfying the preset condition as a target speed limit location point; determining an emergency braking speed according to a relative deceleration of the second speed limit value relative to the first speed limit value corresponding to the target speed limit location point, and performing overspeed protection on the train according to the emergency braking speed.
