The invention relates to a sensor device (5) for a railway system (1), having at least one fibre element (6) suitable for guiding light, said fibre element having at least one Bragg mirror (7) formed with a first frequency range (14) for reflecting light, at least one light source device (8), which is designed to introduce light of the first frequency range (14) into the at least one fibre element (6), and at least one detector device (10), which is designed to detect reflected light. To simplify the sensor device, the invention proposes that the at least one light source device (8) for introducing light into the fibre element (6) is formed with at least one second frequency range (16) that is suitable for fibre optic sensing. The invention also relates to a method for detecting information.
