The invention relates to a method for operating a rail vehicle (15) in a railway system having at least one optical waveguide (2) which is laid next to at least one railway track (1) and into which light pulses are fed, with said optical waveguide (2) being used as a distributed acoustic sensor, and scattered-back light is detected. In order to configure such a method in such a way that it meets stringent safety requirements relatively easily, a rail vehicle (15) with a sound generator (16) which can be adjusted in terms of its frequency spectrum in such a way that it indicates an emergency is used; when the sound generator (16) is activated, an emergency signal (NS) of the rail vehicle (15) is acquired if a frequency spectrum which corresponds to the adjusted emergency frequency spectrum of the sound generator (16) is detected in the scattered-back light. The invention also relates to a railway system.
