A method operates a mobile device in a railway system with at least one optical waveguide which is laid next to at least one railway track and into which light pulses are fed. The optical waveguide is used as a distributed acoustic sensor and detects scattered-back light. In order to be able to identify reliably such a mobile device in a comparatively easy way, the mobile device is provided with a sound generator which can be adjusted with respect to its frequency spectrum in a way which designates the mobile device. The sound generator is adjusted with respect to its frequency spectrum in a way which designates the mobile device by assigning a frequency selection to the mobile device. An identification number signal of the mobile device is acquired by detecting the scattered-back light from the detected frequency selection. A railway system having such a mobile device is also taught.
