A method and a corresponding device enable monitoring the speed of rail vehicles. In order to enable a reduction and simplification of the required system components and a speed monitoring that is not only intermittent, it is provided that the rail vehicle emits a signal, the propagation time of which is evaluated on the track side with regard to the speed. The evaluated signal is transmitted back to the rail vehicle.
